Answer:
Explanation:
The planet can be thought as a solid sphere rotating around its axis. The moment of inertia of a solid sphere rotating arount the axis is
where
M is the mass
R is the radius
For the planet in the problem, we have
Solving the equation for R, we find the radius of the planet:
Using the formula 
for momentum your answer would come out to be: 
Answer:
Voltage is known as potential or in simpler terms “how fast the electrons flow”. Power is a function of voltage times the volume of electrons (current). Power is the ability to do work and is measured in Watts. The higher the voltage the more power you have with the same current (Watts (power) = Volts x Amps.
Explanation:
The coefficient of static friction of the block is 0.068.
<h3 />
<h3>What is static friction?</h3>
This is the force between two bodies in contact and tends to oppose their motion. It is also the force that keeps two bodies at rest
To calculate the coefficient of static friction, we use the formula below.
Formula:
- F = mgμ............. Equation 1
Where:
- F = Horizontal force
- m = mass of the block
- g = acceleration due to gravity
- μ = coefficient of static friction.
Make μ the subject of the equation
- μ = F/mg.............. Equation 2
From the question,
Given:
- m = 3 kg
- g = 9.8 m/s²
- F = 2 N
Substitute these values into equation 2
- μ = 2/(3×9.8)
- μ = 2/29.4
- μ = 0.068.
Hence, The coefficient of static friction of the block is 0.068.

The displacement of your motion during the entire motion is 22.5 m
The given parameters;
- your initial velocity, u = 1.5 m/s
- your final velocity , v = 3 m/s
- time of motion, t = 10 s
The displacement of your motion during the entire motion is calculated from your average velocity and time of motion.
This magnitude of this <em>displacement</em> is calculated as follows;
Thus, the displacement of your motion during the entire motion is 22.5 m.
