8. As you throw a 2.00 x 102 g baseball, your hand moves a distance of 80.0 cm before you release the ball. If you exert an average force of 55.0 N on the ball while it is in your hand, determine:
Answer:
v = 21.0 m / s
Explanation:
In this exercise, it is generally asked to determine the final speed of the ball.
Let's start by finding the acceleration of it
F = ma
a = F / m
let's reduce the magnitudes to the SI system
m = 2.00 102 g (1kg / 1000g) = 0.200 kg
x = 80.0 cm (1m / 100 cm) = 0.800 m
we calculate
a = 55.0 / 0.200
a = 275 m / s
now we can use kinematics, where the ball has an initial velocity of zero and travels a distance x = 80 cm with the force
v² = v₀² + 2 a x
v² = 0 + 2ax
v = [tex]\sqrt{2ax}[/tex]
let's calculate
v = [tex]\sqrt{2 \ 275 \ 0.800}[/tex]Ra 2 275 0.800
v = 20.98 m / s
if we use the criteria of significant figures
v = 21.0 m / s

if you put a pencil in a cup of water, it looks as if it is broken and larger in the water. This is because light waves
Answer:
When light enters from air to water i.e. it is moving from rarer to denser medium, it changes its original path as there is a change of speed of light and deflects itself towards the normal. This is known as the refraction of light and this is why a pencil in a cup of water looks as if it is broken and larger.

A coin falls off a table and is traveling to the ground. Which claim about the forces acting on the coin must be true?
(Choice A)
There is a net force on the coin.
(Choice B)
There are no forces on the coin.
(Choice C)
There is no net force on the coin.
(Choice D)
There is not enough information.
A coin falls off a table and is traveling to the ground. There is a net force on the coin which is responsible for the motion of the coin. Thus, the correct option is A.
What is Net force?The net force can be defined as is the sum of all the forces which are acting on an object. Net force acting upon an object can accelerate its mass. Some other forces also acts on a body either at rest or motion. The net force is used in a system when there is a significant number of forces acting on the object.
A coin which falls off a table and is still traveling to the ground. Then, it can be concluded that there is a net force which is acting on that coin which is responsible for the motion of the coin.
Therefore, the correct option is A.

What is the electromagnetic spectrum?The electromagnetic spectrum refers to the variety of frequencies (the spectrum) of electromagnetic radiation, as well as the wavelengths and photon energies associated with each frequency.
The goal of the electromagnetic spectrum experiment is to determine what elements are present in the atmospheres of the planets and moons by examining their absorption spectrums.
The electromagnetic spectrum encompasses electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz,
The frequency corresponds to wavelengths ranging from thousands of kilometers to a fraction of an atomic nucleus's size.
The electromagnetic waves within each frequency band are given various names, starting at the low frequency (long wavelength) end of the spectrum.
Hence the dependent variable is the one that changes as a result of the independent variable.

What happens to the force between two charged particles if the distance between them is cut in fourth?
Answer: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if the distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

What is the interference of waves?The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.
The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.
From the constructive interference;
[tex]\rm L_1-L_2 = 2 \lambda \\\\ 2\lambda=8-6 \\\\ \lambda= 1 \ m[/tex]
The frequency is;

Explanation:
For an investigation, a teacher dropped a metal bolt into a container of maple syrup and asked students to remove the bolt without touching the syrup. The students first tried to use a strong magnet to remove the bolt, but it remained on the bottom of the container. They finally poured the syrup into another container to get the bolt out. Which of these best describes the bolt’s physical properties?
A.
The bolt is magnetic and less dense than the maple syrup.
B.
The bot is non magnetic and less dense than the maple syrup.
C.
The bolt is non magnetic and more dense than the maple syrup.
D.
The bolt is magnetic and has the same density as the maple syrup.
Choice-C is the right one.
-- The bolt didn't react to the magnet, and just laid there. That tells you that the bolt was made of a non-magnetic material.
-- The bolt didn't float. It went straight to the bottom. That tells you that it's more dense than the fluid around it.
Explain How do the attractions between particles in a fluid determine viscosity?
Answer: Viscosity is due to particle mass, particle shape, and the strength of the attraction between the particles of a liquid. In general, the stronger the attractive forces between particles, the higher the viscosity. For many liquids, viscosity decreases when heat is applied.

how does the sun rise and set
a.earth orbit around the sun
b.The sun is center of solar system
c.earth rotates on it tilted axis and orbit around the sun at the same time
Answer:
c. earth rotates on it tilted axis and orbit around the sun at the same time
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.
Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time
