Explanation:
Our solar system is formed by a dust storm, which created the planets. This info is grabbed by NASA, and people believe this is how the Solar System is formed. The sun is formed like this too.
Answer:
Well a lot of people believes in evolution. But in fact evolution is actually clearly impossible because how can dead which is Non-Living bacteria and dirt make something alive like living. And anyway there's a lot of thing's in nature that shows there is a creator. Like how does bees know when there honey comb is to warm to start fanning there wings to cool the honey comb down? And like human beings for example we didn't generate from aps. Yes there smart like us and sorta human like but the way our bodies are designed is wayyyyy to complicated. For example our brain its a computer we dont shut it on and off it's always running constantly and we dont have to worry about turning our brain on or off. I know this wasent what u have asked but i made me think about it and also someone created the universe because the whole universe hangs on nothing but they stay aligned. So this shows that there is a creator though.

10.(a) At what water depth is the pressure twice atmospheric pressure?
(b) What is the pressure at the bottom of the 11-km-deep in the ocean? Take
atmospheric pressure as 100 kPa and the density of water as 1000 kg/m3.
Answer:
Answer. Pressure under water is given by the sum of atmospheric pressure and pressure of fluid. Thus, depth in water at which pressure will be equal to twice the atmospheric pressure is 10.2 m.

A tuna traveling at 12 m/s starts to decelerate steadily. It comes to a complete stop in 10 seconds. What is its acceleration?
Answer:
a = -1.2 m/s^2
Explanation:
Vi = 12 m/s
Vf = 0 m/s
t = 10 s
Plug those values into the following equation:
Vf = Vi + at
0 = 12 + 10a
---> a = -1.2 m/s^2

If three components are arranged to form a parallel circuit, and the individual resistance of these components are r1, r2, and r3 respectively, the formula for finding the total resistance R is: 1R=1r1+1r2+1r3.
What is the kinetic energy of a
54 kg person, diving into a pool
at a speed of 30 m/s?
Answer:
Explanation:
Formula
KE = 1/2 m v^3
Givens
m = 54 kg
v = 30 m/s
Solution
KE = 1/2 54 * 30^2
KE = 1/2 54 * 900
KE = 27 * 900
KE = 24300 Joules
The work done in lifting a brick of mass 2kg through a height of 5m above the ground will be
(A)2.5J
(B)10J
(C)50J
(D)100J
Answer:
D. 100 J
Explanation:
Given
Mass (m) = 2 kg
Height (h) = 5 m
Acceleration due to gravity (g) = 10 m/s²
Now
Work done(W)
= m * g * h
= 2 * 10 * 5
= 100 Joule
Hope it will help :)❤
The work done in uplifting a brick having a mass of 2kg along with a height of 5m above ground level would be:
D). 100 J
Given that,
Mass of the brick [tex]= 2Kg[/tex]
Height of the brick [tex]= 5m[/tex]
As we know,
Work Done (W) [tex]= mgh[/tex]
where
m = Mass
g = Acceleration due to gravity
h = height
A.T.Q.
By substituting the given values, we get;
[tex]Work Done (W)[/tex] [tex]= 2[/tex] × [tex]10[/tex] × [tex]5[/tex] (taking [tex]g = 10 m/s^2[/tex])
[tex]= 100 J[/tex]
Thus, the work done is 100 J and hence, option D is the correct answer.

Arthur conducts a controlled experiment several times. The results of each test show that his hypothesis is not supported. Which of these best describes why
this hypothesis is still valuable?
Hello. You did not inform the experiment that Arthur is conducting, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The hypothesis is an assumption that is made before the experiment is carried out. This hypothesis is formed with the observation of some phenomenon of nature where the researcher believes that two or more elements interact to form a result. In this case, the experiment is carried out to determine whether the assumption, that is, the hypothesis is false or true. In the event that an experiment determines that the hypothesis is false, two things may have occurred: (a) the experiment was set up, or analyzed incorrectly, (b) the elements tested have no relation to the observed phenomenon.
What is an object in the classroom that has a loose end? Please help!!
Answer:
student's tie cause if the tie is too tight then no need of hanging to fan.
An example of an object in a classroom that has a loose end could be a frayed electrical cord on a piece of electronic equipment such as a computer or a lamp.
What is a classroom?A classroom is an educational circumstance in an academic institution where important personalities are developed and career-building skills are learned.
A frayed electrical cord on a piece of electronic equipment, such as a computer or a lamp, is an example of a loose end in a classroom.
Over time, the cord can become worn or damaged and the outer protective layer can start to come apart, leaving exposed wires and a "loose end" that can be potentially dangerous if not addressed.
This loose end can become a safety hazard as it increases the risk of electrical shock or fire. It is important to address any loose or frayed cords as soon as they are noticed and either repair or replace the equipment to ensure a safe learning environment for students and teachers alike.

How do you increase the potential energy between two south magnetic
poles?
Answer:
A south pole of one magnet can approach the north pole of another. The magnetic fields are aligned. This makes an attractive force between the two magnets. The farther apart they are, the higher their potential energy.
A wave has a wavelength of 4.9 m and a velocity of 9.8 m/s. The medium through which this wave is traveling is then heated so that the velocity is doubled. If the frequency remains constant, what is the wavelength of the heated wave? 2.5 m 9.8 m 14.7 m 19.6 m
Answer:
the wavelength is 9.8 meters
Explanation:
We can use the relationship:
Velocity = wavelenght*frequency.
Initially we have:
wavelenght = 4.9m
velocity = 9.8m/s
then:
9.8m/s = 4.9m*f
f = 9.8m/s/4.9m = 2*1/s
now, if the velocity is doubled and the frequency remains the same, we have:
2*9.8m/s = wavelenght*2*1/s
wavelenght = (2*9.8m/s)*(1/2)s = 9.8 m
Answer:
9.8

What types of changes in motion cause acceleration?
Answer:
Change in velocity and direction over a specific period of time.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate the acceleration of an object.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Hence, the types of changes in motion that cause acceleration is a change in velocity and direction over a specific period of time.
A man stands in front of a vertical plane mirror which is fixed on a
wall as shown in the diagram below. The image formed by the
mirror is also shown.
The man looks at the image of his feet.
a. Complete the ray diagram to show how the man is able to see the
image of his feet in the mirror.
b. What is the purpose of the normal line in the diagram?
c. State which angle does x represent.
d. What's the type and direction of the image formed by the mirror?
Answer:
a) ray horizontal and ray leaves his feet
b) The normal line respect to which the angles are measured,
c) The angle x is the reflected angle
d) virtual image, right image
Explanation:
a) To complete the rays, you must draw a horizontal ray at the height of the man's head, this ray touches the mirror perpendicularly, therefore it bounces in the same direction.
The other ray leaves his feet and touches the mirror at one point, it is reflected with the same angle, by the law of reflection and reaches the eyes of man, the brain creates an extension of this ray and at the point of the floor creates the image point.
b) The normal line is a line perpendicular to the surface with respect to which the angles are measured,
c) The angle x is the reflected angle, which is equal to the incident angle according to the law of reflection
d) The image is formed by the prolongation of the rays of light, therefore it is a virtual image and as it has the same direction of the man it is a right image
