Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity. Good luck on your assignment and have a great day! :D
Remains the same
Explanation:
According to Gauss's law, the electric flux through a closed surface is proportional to the charge enclosed by the surface. So no matter how big or small we make the surface that encloses the charge, the electric flux remains the same because it only depends on the enclosed charge, not surface area.
Answer:
20,000,000 N
Explanation:
First find the acceleration:
a = Δv / Δt
a = (0 − 40 m/s) / 0.010 s
a = -4000 m/s²
Next use Newton's second law to find the force on the car:
F = ma
F = (5000 kg) (-4000 m/s²)
F = -20,000,000 N
According to Newton's third law, the force on the wall is equal and opposite the force on the car.
F = 20,000,000 N
Answer:

Explanation:
The equations of kinematics will be used to solve this question:

At its maximum height, the projectile has zero velocity in the y-direction. But its velocity in the x-direction is unaffected.
First, let's apply the above equations to the x-direction.
There is no acceleration in the x-direction. So, its velocity in the x-direction is constant during the motion.

Therefore, the velocity vector of the projectile is

The speed of the projectile is the same.
The acceleration vector is constant during the motion and equal to the gravitational acceleration, which is -9.8 downwards.
