PLEASE HELP ASAP 4. Which statement best describes elastic and inelastic collisions most accurately?
a. Momentum is not conserved in both elastic and inelastic collisions
b. Momentum is only sometimes conserved in both types of collisions, because sometimes
an object slows down after a collision, which means the object lost momentum.
Momentum is always conserved in elastic collisions, but only sometimes conserved in
inelastic collisions because momentum is lost when the objects stick together.
d. Elastic collisions have objects that bounce apart after the collision, while in inelastic
collisions the objects stick together. Momentum is conserved in both types of collision.

Why is air warmer near Earth's surface?
A.
The Sun heats Earth's surface, and in turn the air above it is heated.
B.
Warm air is more dense and sits on top of Earth's surface.
C.
Warm air is less dense and sits on Earth's surface HELP PLZ!!
Answer:
I am pretty sure it is A!
:D
The air is warmer near Earth's surface because warm air is denser and sits on top of the Earth's surface. The correct option is B.
What is air density?The mass of the air per unit volume is known as the air density. Its unit is kg/m³.
Due to the lower pressures in the air above, air expands when it rises. cooling air expands.
The hottest temperatures in the troposphere are often found at the earth's surface because the sun heats the atmosphere predominantly from the surface and because the air cools as it ascends.
Because warm air is denser and lies on top of the surface of the Earth, it is warmer near the surface of the earth.
Hence, the correct option is B.

Newton theorized that the apple would experience the accelerating effect of the force of gravity no matter how far from the Earth the apple was. He expanded this idea to all objects near the Earth. What was Newton's explanation for why the moon doesn't crash to the Earth due to gravitational force? Do we use this principle for any application today? Give an example, if so.
Answer:
The moon also falls towards the Earth, but having a tangential speed, the acceleration it has is used in the change of direction of its speed,
Explanation:
Newton explained that all objects attract each other, as the Earth is much greater than the apple, it is this that falls towards the Earth.
The moon also falls towards the Earth, but having a tangential speed, the acceleration it has is used in the change of direction of its speed, in general this acceleration is called centripetal
[tex]a_{c} = g[/tex]
This principle is used in all circular motion devices, for example the merry-go-round in parks, the radius of the circle is proportional to the speed of the turn and therefore to the centripetal acceleration of the device.

Which type of electromagnetic waves make up the colors of a rainbow seen after a storm?
A. visible light
B. infrared light
C. X-rays
D. ultraviolet light
Answer:
we conclude that visible light is that electromagnetic wave that makes up the colors of a rainbow seen after a storm.
Hence, option A is correct.
Explanation:
Generally, after the storm, we can witness the presence of a rainbow with our naked eyes. Rainbow, visible to our eyes, consists of all the seven constituent colors of white light. Those seven colors range from violet to red, all having different wavelengths. When water particles present in our atmosphere get exposed to light, all the constituent colors of a white light tend to deviate at a variety of angles. It happens due to their refraction through water particles; thus, a spectrum is obtained.
As we cannot see X-rays, UV rays, and infrared waves through our naked eye, visible light is the kind of electromagnetic wave that makes anyone able to see the objects.
Please note that all the constitute colors of a beautiful rainbow associate with the visible region of the electromagnetic spectrum.
Therefore, we conclude that visible light is that electromagnetic wave that makes up the colors of a rainbow seen after a storm.
Hence, option A is correct.
Answer: A.) Visible light

A book of a mass 0.5kg is dropped from a height of 2.8m. How much mechanical energy does it have right before it hits the ground? (Assume there is no air resistance.) Acceleration due to gravity is g= 9.8 m/s^2.
Answer:
13.7 J
Explanation:
In absence of air resistance, the mechanical energy of the object is conserved during the fall: this means that the initial gravitational potential energy that it has at the beginning of the fall will be entirely converted into kinetic energy when the book is just about the hit the ground.
Therefore, this also means that we can calculate the mechanical energy at the beginning of the fall, as this will be equal to the mechanical energy just before the book hits the ground.
At the beginning of the fall, the mechanical energy is all gravitational potential energy:
where
m = 0.5 kg is the mass of the book
is the acceleration of gravity
h = 2.8 m is the height above the ground
Substituting,
The more oxygen the muscles receive, the more energy you have

The pink car has a velocity of 4.4 m/s to the right while the blue car has a velocity of 6.8 m/s to the left. If the two cars crashed and stuck together, what would their combined momentum be afterwards and what direction would they be moving
Given :
The pink car has a velocity of 4.4 m/s to the right while the blue car has a velocity of 6.8 m/s to the left.
To Find :
If the two cars crashed and stuck together, what would their combined momentum be afterwards and what direction would they be moving.
Solution :
Let, combined velocity of the car is v.
Also, let us assume that mass of both the cars are equal and it is m.
By conservation of momentum :
Initial momentum = Final momentum
m( 6.8 ) - m( 4.4 ) = 2mv
2mv =2.4m
v = 1.2 m/s
Therefore, the velocity of combined car after crash is 1.2 m/s .

A fish is 4.7 cm from the front surface of a fish bowl of radius 21 cm. Where does the fish appear to be to someone in air viewing it from in front of the bowl? Do not forget the proper sign. (Give your answer in cm.)
______ cm
Where does the fish appear to be when it is 38.9 cm from the front surface of the bowl? (Give your answer in cm.)
______ cm
Answer:
Explanation:
From the information given:
We can properly determine the distance where the fish appear in the air viewing it from in front of the bowl by using the formula:
[tex]\dfrac{n_i}{d_o}+\dfrac{n_2}{d_1}= \dfrac{n_2-n_1}{r}[/tex]
where;
[tex]n_1[/tex] = refractive index in the air; = 1.33 &
[tex]n_2[/tex] = refractive index in water. = 1
[tex]\dfrac{n_2}{d_i}= \dfrac{n_2-n_1}{r}-\dfrac{n_1}{d_o}[/tex]
[tex]\dfrac{1}{d_i}= \dfrac{1-1.33}{-21 \ cm}-\dfrac{1.33}{4.7\ cm}[/tex]
[tex]\dfrac{1}{d_i}= - 0.26726 \ cm[/tex]
[tex]d_i =\dfrac{1}{ - 0.26726 \ cm}[/tex]
[tex]\mathbf{d_i }[/tex] = - 3.74 cm
2)
To determine where the fish appear to be when it is 38.9 cm from the front surface of the bowl by using the formula:
[tex]\dfrac{n_2}{d_i}= \dfrac{n_2-n_1}{r}-\dfrac{n_1}{d_o}[/tex]
[tex]\dfrac{1}{d_i}= \dfrac{1-1.33}{-21 \ cm}-\dfrac{1.33}{38.9\ cm}[/tex]
[tex]\dfrac{1}{d_i}=- 0.0184759 \ cm[/tex]

After 4 half-lives, I ended up with 10 gram sample of
Carbon-14. What was the original amount of Carbon-14
that I started with?
Answer:
80g
Explanation:
The half - life is the time taken for half of radioactive substance to decay to half of its original composition.
After 4 half lives, the carbon - 14 sample is 10grams
Now let us trace the decay of this substance;
At the 3rd half life, it will have double the amount at the 4th half life;
2 x 10 = 20g
At the 2nd half life, there will be double the amount at the 3rd half life;
20 x 2 = 40g
Originally, we are going to have;
40 x 2 = 80g

A 0.50-kg ball is thrown vertically upward with an initial velocity of 35 m/s. Approximately, how high will the ball rise?
Answer:
62.5m
Explanation:
Given parameters:
Mass of the ball = 0.5kg
Initial velocity = 35m/s
At the maximum height final velocity is 0m/s
Unknown:
Height of the rise of the ball = ?
Solution:
To solve this problem, we apply the right motion equation which is shown below;
v² = u² - 2gh
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
h is the height
Now insert the parameters and solve;
0² = 35² - 2(9.8)(h)
-1225 = -19.6h
h = 62.5m
