Explanation:
If V is the original volume, V' is the new volume, T is the original Kelvin temperature, and T' is the new Kelvin temperature, how is Charles's law expressed mathematically
Answer:
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]
Explanation:
Given the following data;
Original volume = V
New volume = V'
Original temperature = T
New temperature = T'
To write an expression for Charles's law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles law is given by the formula;
[tex] \frac {V}{T} = K[/tex]
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]

A marble block of mass 2 kg lying on ice when given a velocity of 6 m/s is stopped by a friction in 10s then what is the coefficient of friction?
Answer:
[tex]\mu=0.06[/tex]
Explanation:
Given that,
Mass of a block, m = 2 kg
Velocity of the block, v = 6 m/s
It stopped in 10 s
We need to find the coefficient of friction.
The frictional force is balanced by the opposing force such that,
[tex]\mu mg=ma\\\\\mu=\dfrac{a}{g}[/tex]
Where
a is acceleration, a = 6/10 = 0.6 m/s
So,
[tex]\mu=\dfrac{0.6}{10}\\\\\mu=0.06[/tex]
So, the coefficient of friction is equal to 0.06.

How many electrons does an atom require to have a stable configuration? How is this achieved in an ionic bond? How is this achieved in a covalent bond?
Answer:
How many electrons does an atom require to have a stable configuration?
eight electrons
In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
How is this achieved in an ionic bond?
Ionic bonds are a class of chemical bonds that result from the exchange of one or more valence electrons from one atom, typically a metal, to another, typically a nonmetal. This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond.
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outermost (valence) electrons, atoms can fill up their outer electron shell and gain stability.

A person in a kayak starts paddling, and it accelerates from 0 to 0.509 m/s in a distance of 0.555 m. If the combined mass of the person and the kayak is 63.4 kg, what is the magnitude of the net force acting on the kayak
Answer:
the magnitude of the net force acting on the kayak is 14.77 N.
Explanation:
Given;
initial velocity of the kayak, u = 0
final velocity of the kayak, v = 0.509 m/s
distance traveled by the kayak, d = 0.555 m
combined mass of the person and kayak, m = 63.4 kg
Determine the acceleration of the kayak by using the following kinematic equation;
v² = u² + 2ad
(0.509)² = 0 + (2 x 0.555)a
0.259081 = 1.11a
a = 0.259081 / 1.11
a = 0.233 m/s²
The magnitude of the net force acting on the kayak is calculated by using Newton's second law of motion;
F = ma
F = 63.4 x 0.233
F = 14.77 N
Therefore, the magnitude of the net force acting on the kayak is 14.77 N.

Dish-shaped reflectors are used to steer microwaves in order to establish communications links between nearby buildings. Those reflectors are often made from metal mesh. Why don't they have to be made from solid metal sheets
A "screen" or even just a set of parallel bars are highly reflective to electromagnetic waves as long as the open spaces are small compared to the wavelengths.
"Grid" dishes work fine ... with less weight and less wind resistance ... for frequencies below about 3 GHz. (Wavelengths of at least 10 cm.)
(I even worked on a microwave system in South America where huge grid dishes were used on a 90-mile link.)

c)
The image is real, inverted, and enlarged.
d)
There is no image.
Answer:
C
Explanation:

The image results when the object is located between 2f (2 focal lengths) and f (the focal point) of a convex lens will be real, inverted, and enlarged.
What is a convex lens ?An optical lens is made up of two spherical surfaces is a convex lens The lens is called a biconvex lens or simply convex lens if those surfaces are curved outwards.
Converging lens is another name for it. It's because it brings all the light rays that are parallel to the primary axis together at the focus point (F).
The image results when the object is located between 2f (2 focal lengths) and f (the focal point) of a convex lens will be real, inverted, and enlarged.
Hence, option C is correct.

5.) What is the missing element? *
a. Hydrogen
b. Helium
c. Boron
d. Oxygen
Answer:
Explanation:
This question is showing a stoichiometric reaction. But the out put is Helium and nitrogen. while the input has Hydrogen and something else. Hydrogen doesn't turn into different elements. So I think the question is wrong. But, He is missing , and so is the nitrogen, but since that's not a choice, maybe they hope you'll put He ?? :/ But like I said , the question is just wrong.

An object is traveling on a circle with a radius of 6 feet. If in 80 seconds a central angle of 9/4 radians is swept out, then find both the angular speed and the linear speed of the object. Give exact answers. DO NOT provide a decimal approximation.
Answer:
The angular speed of the object is 0.0281 rad/s
The linear speed of the object is 0.169 ft/s
Explanation:
Given;
radius of the circle, r = 6 ft
time of motion of the object around the circle, t = 80 s
central angle formed by the object during the motion, θ = 9/4 rad = 2.25 rad
The angular speed of the object is calculated as;
[tex]\omega = \frac{\theta }{t} = \frac{2.25 \ rad}{80 \ s} = 0.0281 \ rad/s[/tex]
The linear speed of the object is calculated as;
v = ωr
v = 0.0281 rad/s x 6ft
v = 0.169 ft/s

If all your cells were the same, could you still do everything you do now?
Explain.
Answer:
No, you couldn't function the same as you do now.
Explanation:
This is because each cell follows individual tasks, and makes up specific parts of a body. For example, if all of your cells were those of an eye, you would be missing the components of arms, legs, etc.
Answer: No
Explanation: If all the cells of our body were of the same size, shape and volume, then they would all perform the same function and the multitude of other important functions cannot be carried out, without which human life itself would not be possible.
If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a __________________ on a heating curve, which occur at the __________________ and ____________________.
Answer:
1. Plateau where the temperature stays constant
2. Melting
3. Boiling points of the substance
Explanation:
The relationship between kinetic energy and temperature is given as follows;
[tex]\overline E = \dfrac{3}{2} \times \dfrac{R}{N_A} \times T[/tex]
Where;
[tex]\overline E[/tex] = The average kinetic energy of the atom
R = The universal gas constant
[tex]N_A[/tex] = Avogadro's number
T = The temperature in Kelvin
Therefore, the kinetic energy increases as the temperature increases, however when the energy is not being converted into kinetic energy, the energy is stored as internal potential energy in the melted or evaporated state of the substance
Therefore, we have;
If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a 1. plateau where the temperature stays constant on a heating curve, which occur at the 2. melting and 3. boiling points of the substance.
Hi, please help me this question
A student connects a circuit
with a cell, an ammeter, and a
buzzer and listens to the buzzer.
She adds another cell.
Describe and explain what
happens to the current
Answer:
let the voltages of the cell be V and R the equivalent resistance of the circuit.
I1=RV∵ only one cell connected ;
I2=RV+V=R2V∵ two cells connected in series ;
I3=RV+RV=R2V∵ two cells connected in parallel ⇒ total current is same as sum of the currents due to each.
Now ,
LHS = 3I3I2=3R2VR2V=3(R24V2)
RHS = 2I3(I1+I2)=2R2V(RV+R2V)=2R2VR3V=3R2therefore, LHS = RHS
