D, when a moving car suddenly stops, your body is still moving forward until the seatbelt stops you.
When things move, there is always friction. It's what makes cars move in the first place. The inside of the car doesn't move, however the wheels on the car are moving at a rapid pace. When the car stops violently, everything inside the car is thrown. The seat belt acts as a safety precaution if an accident happens.

Answer:
Explanation:
The three main particles that make an atom are:
- Proton: its mass is , it carries an electric charge of +e (
), and it is located in the nucles of the atom
- Neutron: its mass is 
, it carries no electric charge, and it is also located in the nucleus of the atom
- Electron: its mass is 
, it carries an electric charge of -e (), and it is located outside the nucleus
Answer:
9N
Explanation:
static friction=normal force x coefficient of static friction
so static friction =30N x 0.3= 9N
Answer:
The crate was being lifted by a height of 1.48 meters.
Explanation:
In an attempt o move a crate;
Force applied = 2470 N
Work done by the force = 3650 J
We know that the work done is defined as the force used to move an object to a distance.
Given the Force used and the work done by that Force, we need to find out the distance the crate was lifted to.
Work done is defined as:
Work = Force*distance covered in the direction of the force
3650 = 2470*distance
distance = 3650/2470
distance = 1.48 meters
