Answer:
5.1 m
Explanation:
Assuming gravitational force is 9.8 m/s², the acceleration experience by the ball is -9.8 m/s²
The acceleration is negative because the ball is moving vertically upward and gravitational force acts vertically downward.
The velocity of the ball at maximum height is 0 m/s when it will start falling back to ground at a positive acceleration of 9.8 m/s²
We can use the following formula to calculate the height the ball reaches
v² = u² + 2 a d
where u is the initial velocity, v = final velocity, a = acceleration and d = displacement(in this case the vertical height from ground)
Final velocity is 0 since the ball has reached it maximum height and starts falling downward, Initial velocity u = 10 m/s
Plugging in values we get
0² = 10² - 2 x 9.8 x d
0 = 100 - 19.6d
Subtracting 100 from both sides
-100 = -4.9 d
Divide by -1 both sides
100 = 4.9d
d = 100/4.9 ≈ 5.1 m
So the ball will reach a height of 5.1m
explain your observations: what do you think happened to the light from the lightbulb as it passed through the gas cloud before passing through the spectroscopy telescope?
If a gas of hydrogen atoms lies between you (your telescope + spectrograph) and a continuum light source, it will create an absorption line spectra, and if viewed from a different angle, an emission line spectrum.
Absorption lines allude to the propensity of cool atmospheric gas to absorb the same lines of light, whereas emission lines refer to the fact that burning hot gas produces lines of light.
Some of the light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands. The wavelengths of light released when common materials were heated to form lines that became known as "spectral lines" were recorded.

Sphere A is located at the origin and has a charge of +2.0 × 10- C. Sphere B is located at +0.60 m on the x-axis and has a charge of -3.6 x 10- C.
Sphere C is located at +0.80 m on the x-axis and has a charge of +4.0 x 10-6 C. Determine the net force on sphere A.
Answer:
F = 0.0675 N
Explanation:
The net force under sphere A is the sum of the force made by sphere B with the force made by sphere C.
By Coulomb's Law of force, we have:
F = k * Q*Q/d²
So:
Force (absolute value) of C on A:
F₁₃ = k * Q₁*Q₃/d²
F₁₃ = 9*10⁹ * (2.0*10⁻⁶)*(4.0*10⁻⁶) / (0.80)²
F₁₃ = 9/80 N = 0.1125 N
The vector:
F₁₃ = 0.1125 N (horizontal direction; pointed to the left side: repulsive)
Force (absolute value) of B on A:
F₁₂ = k * Q₁*Q₂/d²
F₁₂ = 9*10⁹ * (2.0*10⁻⁶)*(3.6*10⁻⁶) / (0.60)²
F₁₂ = 9/50 = 0.18 N
The vector:
F₁₂ = 0.18 N (horizontal direction; pointed to the right side: attractive)
The net force is F₁₂ - F₁₃:
F = 0.180 - 0.1125
F = 0.0675 N

Charles's LawCharles's Law consists of the relationship between the volume and temperature of a certain amount of ideal gas.
This law says that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases, and as the temperature decreases, the volume of the gas decreases: the volume is directly proportional to the temperature of the gas.

Timmy is playing on a moving walkway like you find in an airport. He wants to have fun and decides to run backward on the moving walkway at 1.6 m/s with respect to the moving walkway he is on. Both Timmy and the moving walkway are going in the opposite directions. The walkway is going at 6.9 m/s. What speed is Timmy going with respect to a person watching this endeavor who is standing on solid ground beside the walkway?
The relative velocity is obtained as 5.3 m/s from the calculation as shown below.
What is motion?We know that motion refers to the change in the position of an object with time. Give that we know that motion is relative and the position of the two objects that are in motion must always be taken into consideration. In this case, we have the situation in which Timmy and his friends are moving backwards and the runway is moving forward thus they are actually moving in opposite directions as seen.
Let us note that velocity is a vector quantity hence we have to assign the forward direction as positive and the backwards direction as negative. Thus we can then take the relative motion between Timmy and his friend and the walk way can be obtained quite conveniently by the use of;
6.9 m/s - 1.6 m/s = 5.3 m/s
