Nucleotides are organic compounds made up of a phosphate and a nucleoside. They function as monomeric units of the key macromolecules found in all living forms on Earth, deoxyribonucleic acid (DNA), and ribonucleic acid (RNA), which are both nucleic acid polymers. In addition to being produced by the liver from common nutrients, nucleotides can also be received through diet.
A nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group made up of one to three phosphates are the three component molecules that make up a nucleotide. Guanine, adenine, cytosine, and thymine are the four nucleobases found in DNA; uracil is used in place of thymine in RNA. These four nucleobases are necessary for a variety of cellular processes, such as the synthesis of amino acids, proteins, and cell membranes, as well as for moving the entire cell and its constituent parts.

we investigated a jet landing on an aircraft carrier. in a later maneuver, the jet comes in for a landing on solid ground with a speed of 87 m/s, and its acceleration can have a maximum magnitude of 8.55 m/s2 as it comes to rest. (a) from the instant the jet touches the runway, what is the minimum time interval needed before it can come to rest? (b) can this jet land on a small tropical island airport where the runway is 0.800 km long? (c) explain your answer.
For a successful landing the aircraft will need:
(a) A time from the instant the jet touches the runway of: 10.1754 s(b) A distance of: 0.44263 km(c) Due to the jet need just 0.44263 km of distance to landing it can land on a small tropical island airport where the runway is 0.800 km longThe formula for uniformly varied rectilinear motion (UVRM) and procedure we will use to solve this exercise is:
vf = vi + (a * t)x = (vf²-vi²)/ (2a)Where:
x = distancevf = final velocityvi = initial velocitya = accelerationInformation about the problem:
vf= 0 m/svi = 87 m/sa = -8.55 m/s²t =?x= ?Applying the final velocity formula, and clearing the time we get:
vf = vi + (a * t)
t = (vf – vi) /a
t = (0 m/s – 87 m/s) /-8.55 m/s²
t = -87 m/s/ -8.55 m/s²
t = 10.1754 s
Applying the distance formula, we get:
x = (vf²-vi²)/ (2a)
x = [(0 m/s)²- (87 m/s)²]/ (2 * -8.55 m/s²)
x = (0 m²/s²- 7569 m²/s²)/ -17.1 m/s²
x = -7569 m²/s²/ -17.1 m/s²
x = 442.63 m

four point charges, each of magnitude 9.66 µc, are placed at the corners of a square 87.1 cm on a side. if three of the charges are positive and one is negative, find the magnitude of the force experienced by the negative charge. the value of coulomb’s constant is 8.98755 × 109 n · m2 /c 2 .
The magnitude of the force experienced by the negative charge is 0.198N.
The Coulombs law is an expression that states that magnitude of the force between two charges q and Q separated by a distance r is given by
F=k|Q|q|r2
where k is Coulomb constant.
Answer and Explanation:
Let us visualize corners of the square as four points on the xy-axis. The four points would be origin (0,0), then (78.9 cm, 0), then (0, 78.9 cm) and (78.9 cm, 78.9 cm). These points are corners of the square described in the question. Let negative charge be at origin. Let charge 1 be located at (78.9 cm, 0), that is, its located along x-axis, a distance 78.9 cm away from the negative charge. The force due to this charge 1 acts in positive x-direction as the two charges attract. Let charge 2 be at point (0, 78.9 cm) and the force due to this charge acts in the positive y-direction. Charge 2 is also 78.9 cm away from negative charge. Let charge 3 be located at point (78.9 cm, 78.9 cm). Force due to this charge has the x and y-components. The angle this force makes with positive x-axis is 45 degrees since this is a square. The distance between charge 3 and negative charge is
√(78.9cm)2+(78.9 cm)2 =111.5814501cm.
Now we can calculate force on the negative charge due to each individual positive charge. Force due to the charge 1 is [tex]F_{1} =k|+q||-q| r^{2}(8.98755*109N.m^{2}/C^{2})*(2.68*106)*(2.68*106)^{2}(0.789m)^{2} =0.1036947816N[/tex]
in positive x-direction. Force due to the charge 2 has same magnitude as force due to charge 1, but acts in the positive y-direction.
F2 =0.1036947816N
The force due to the charge 3 is
[tex]F_{3}=k|+q||-q| r^{2} =(8.98755*109N.m^{2}/C^{2})*2.68*10^{-6} )^{2}(1.115814501m)^{2}= 0.05184739076N[/tex]
The x and y-components of force due to charge 3 are
F3,x=F3cos45=(0.05184739076√22)N=0.03666164159N
in positive x-direction, and
F3,y=F3sin45=(0.05184739076√22)N=0.03666164159N
in positive y-direction.
Therefore, x-component of the resultant force experienced by the negative charge is
Fx=F1+F3,x=0.1036947816N+0.03666164159N=0.1403564232N
and y-component is
Fy=F2+F3,y=0.1036947816N+0.03666164159N=0.1403564232N
Therefore, magnitude of the force experienced by the negative charge is
[tex]F= \sqrt{Fx_{2}+F_{2y} }= \sqrt{(0.1403564232N)^{2}+(0.140356432N)^{2} } =0.198493973N[/tex] =0.198N

If a tennis ball bounces on the floor three times. if each time it loses 22% of its energy due to heating, the height it will rise after the third bounce, provided we released it 3.1 m from the floor is 1.4725 m.
What is energy loss due to heating?
The deliberate or accidental transfer of heat from one material to another is known as heat loss. Radiation, convection, and conduction can all contribute to this. When a component comes in direct touch with another component, whether it is insulated or not, conduction frequently happens. When a pipe, electric heater, or other component has an air barrier surrounding it, convection occurs. When there is no touch and heat is transmitted as waves, radiation results.
given,
Height = 3.1 m
Energy loss = 22%
Let, the total energy be equal to 1 unit
Balance of energy after first collision = 0.78 x 1 unit
= 0.78 unit
Balance after second collision = 0.78 ^2 unit
= 0.6084 unit
Balance after third collision = 0.78 ^3 unit
= 0.475 unit
Height achieved by the third collision will be equal to energy remained
H be the height achieved after 3 collision
0.475 ( m g h) = m g H
H = 0.475 x h
H = 0.475 x 3.1 m
H = 1.4725 m

The resolution of radio telescopes suffers greatly from the large wavelengths of the light they are observing. What can be done to a radio telescope to improve its angular resolution?.
make its dish bigger to improve its angular resolution
Because the wavelengths of radio waves are so larger than the wavelengths of visible light, radio telescopes must be much larger than optical telescopes. The wavelengths of radio waves range from 3 km to 1 cm, while the wavelengths of visible light range from 4 x 10-7 m (ultraviolet) to 7 x 10-7 m. (red). The degree of detail that can be observed in an area of the sky is measured in terms of angular resolution. More detail can be seen at a given wavelength with a larger telescope. The wavelength of the light or radio waves being observed by the telescope (λ) and the telescope's diameter (D) can be used to compute the angular resolution (θ) of the telescope.
θ = 2.5 × 105 × λ/D
θ = 1.22 × λ/D
The ability of any image-forming tool, such as a optical or radio telescope, a microscope, a camera, or an eye, to differentiate minute features of an object is known as angular resolution, and as such, it is a key factor in determining picture resolution.

A catapult can project a projectile at a speed as high as 37.0 m/s. If air resistance can be ignored, how high (in m) would a projectile launched at this speed rise if projected straight up?
The height of the projectile is 69.7 meters when air resistance can be ignored.
The initial speed (u) of the projectile is = 37 m/s
The final speed (v) is 0 because, at a high point, the projectiles come at the rest condition.
The acceleration is negative when the project is thrown in an upward direction. Therefore, the acceleration is, a = -g
Or, a = -9.81 m/s²
Now, by using the kinematics equation, we can find the height of the projectile.
v² = u² + 2gh
(0 m/s)² = (37 m/s)² + 2(-9.81 m/s²)h
2(9.81 m/s²)h = (37 m/s)²
Or, h = (37 m/s)²/ 2(9.81 m/s²)

Newton’s second law relates an object’s acceleration to its mass and the net force acting on it. Does newton’s second law apply to a situation in which there is no net force? select the best explanation.
No, the statement does not justify the situation because when the Net Force is 0 then it means that Inertia is greater than Force. So, it follows Newton's first law of Motion
The first law of motion which is often referred to as the 'Law of Inertia' states that an object tends to remain in the motion it's set in. If the object is set in motion it'll tend to be in motion or if the object is at rest then it'll tend to stay at rest. The object will only change its position when an external force is applied to it.
This tendency to remain in its state of motion is called 'Inertia' which acts as a resistance force when an external force is applied. If the magnitude of the external force is less than the Inertia object will not change its state of motion. So when the net force applied to an object is 0 the object will follow the Law of Inertia.

Since you ran halfway across the stadium, a certain amount of distance has been covered. The only way the average speed can be zero is if you remained stationary over a given interval of time.
In a distance-time graph, at the halfway point in the stadium, slope is equal to zero. So, Instantaneous speed is zero. In a Velocity-time graph, at the halfway point in the stadium, slope is equal to zero. So, Instantaneous acceleration is zero. In a Velocity ( w.r.t. time )-time graph, at the halfway point in the stadium, slope is equal to zero. So, Average acceleration is zero.
Therefore, when you are halfway around the stadium, average speed value cannot be 0.

identify the conditions under which a given system of forces can be reduced to a single force. (check all that apply.)
The condition under which a system of forces is reduced to a single force is - One can replace the force - couple system at O by a single force R acting along a new line of action if R and vector M₀ are mutually perpendicular.
What is a force?
A force is a push or a pull on an object and it is a vector quantity.Therefore, it has both direction and magnitude.Force can cause a change in the velocity of an object.Friction is created because of the force.The formula of force is a product of mass and acceleration.Hence, the only condition is if R and vector M₀ are mutually perpendicular, then the system of forces can be reduced to a single force.

What do you observe when you switch on your light source and hold your largest plastic shopping bag square between the light source and the wall?
When we set the object adjacent to the flashlight and not exactly into its beam of light, we probably won't initially notice a shadow.
However, if we place the object directly in the path, we should be able to see a shadow of it on the wall.
What is shadow?
A shadow, or black place, is produced whilst an opaque item deflects light from a mild source. at the back of a light-emitting gadget, it fills the whole three-dimensional area. A 2-D backward projection of the object obstructing the mild may be used to conceptualise the cross section of a shadow.
mild goes in a directly line, therefore setting an object subsequent to a flashlight however out of the mild's direct route prevents us from seeing a shadow. because the object became out of the mild's direct direction, it was not able to block the light from the flashlight's source.

Can you someone me I’m stuck on this question
alex goes cruising on his dirt bike. he rides 700 m north, 300 m east, 400 m north, 600 m west, 1200 m south 300 m east and finally 100 m north. what distance did he cover? what was his displacement? (use 1cm
He started from point O . After traveled he reached at the same point O.
from the graph given which is attatched :
OA = 700m ab = 300 m bc = 400m
CD = 600m DE = 1200m EF = 300m and FO = 100m
total distance covered = 700+ 300 + 400 + 600 + 1200 + 300 + 100
= 3600m
hence he covered 3600m distance
since, he started from point O and after travelled he reaches the same point from where he started means the initial and final position is same
therefore the total displacement is zero
displacement = 0
