Answer:
I think its uniform I dont really know
Answer
From
V=Distance/time
The distance round a circular path or Object is 2πr
so
v=2πr/T
Making T(period) subject
T=2πr/v
where v is the linear velocity.
We don't have the velocity but we can get it.
The Moon and Earth exert gravitational force on each other and the Moon is kept in Orbit by Centripetal force.
Since the Moon doesn't fly out of Orbit... it must mean that the Gravitational force being exerted on it by the Earth is equal to its centripetal Force.
Equating Both (Fg=Fc)
Fg=GMm/R²
Fc=mv²/r
GMm/R² = mv²/R
Canceling out "m" and "r" on both sides
we're left with
V²=GM/R
V=√GM/R
Where M= Mass of Earth (5.98x10^24)
R=Distance between the center of earth and the Moon
G= Gravitational Constant(Value 6.67x10^-11)
V=√6.67x10^-11 x 5.98x10^24/(3.82x10^8)
V=1021.84meters per second.
Now
T=2πr/v
=2π x 3.82x10^8 / 1021.84
T=2.35x10^6seconds
Converting to days by dividing by(24 x 3600)
You have
T=27.2days approx.

The net force applied to it is 6311.9 N.
To calculate the net force to the car, first, we need to find the acceleration using the equation of motion.
Force: This as be defined as the product of mass and acceleration of a body. The S.I unit of force is Newton (N)
⇒ Formula
- S = ut+at²/2................. Equation 1
⇒ Where:
- u = Initial velocity
- S = Distance
- t = Time
- a = acceleration
From the question,
⇒Given:
- S = 40 m
- t = 3.0 s
- u = 0 m/s (at rest)
⇒ Substitute these values into equation 1
⇒ Solve for a
- 9a = 80
- a = 80/9
- a = 8.89 m/s²
⇒ To get the force, we use the formula below
- F = ma .................... Equation 2
⇒ Where:
- F = Force applied
- m = mass of the car
⇒ Given:
⇒ Substitute these values into equation 2
Hence the net force applied to it is 6311.9 N.

Answer:
Protons
Explanation:
Have a charge of +1 and a mass of 1
Yes. The line is increasing. The flat line at the top of the graph is where there is not acceleration and the decreasing line is deceleration.
