These collisions are: "a Vehicle Collision, a Human Collision, Internal Collision." A vehicle collision is a collision that involves two or more vehicles and is when the vehicles collide against each other creating a unbalanced force since how the force comes from opposite directions. A human collision would involve a vehicle and a human which would also be a unbalanced force but the human wouldn't have much affect of it's speed. A internal collision is when something happens inside the vehicle which decreases, or increases the vehicles speed.

We have that the electric field at the center of the metal ball due only to the charges on the surface of the metal ball is
From the question we are told that
A solid metal ball of radius 1.5 cm
bearing a charge of -15 nC is located near a hollow plastic ball of radius 1.9 cm bearing
uniformly distributed charge of -7 nC
The distance between the centers of the balls is 9 cm
Generally the equation for the electric field is mathematically given as

Explanation:
Solution,
Given:-
- Length=10 cm
- Width= 20 cm
- Height= 5 cm
- Volume =?
Now,
By using the formula of volume of a cuboid, we have
- volume=length×width×height
- volume=10 cm×20 cm×5 cm
- volume=1000 cm³
- volume= 1×10×10×10×10 cm³
- volume=(1×10⁴) cm³
Hence, last option is the correct answer.
Answer:
11.72 mm
Explanation:
The gravitational potential energy equals the potential energy of the spring hence
where m is the mass of object, g is the acceleration due to gravity, h is the height, k is the spring constant and x is the extension of the spring
where \theta is the angle of inclination and d is the sliding distance
Making x the subject then
Substituting the given values then
Answer:
The rate at which work is done would be power. Bonus: The SI unit of work is Joules.
