Answer:15metre per second squ
I
Explanation:
acceleration=(final velocity-initial velocity)÷t
acceleration=(180-120)÷4
acceleration=60÷4
acceleration=15 metre per second square
Answer:
9,000 N.
Explanation:
Workdone can be defined as the ability to do work. It is also the product of the force and the distance it is being moved.
Mathematically,
W = F * d
= 180,000/2
= 90,000 N.
Weight of the 10 cars = 90,000 N.
Weight of a car = 90000/10
= 9,000N.
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

Static electricity is electricity produced locally that does not flow. It is produced by electrons being rubbed off one object and collecting on another. It cannot flow through a wire like the electricity in your home.
Example:
1) Rub a balloon on your hair and it will stick to the wall. The balloon rubs electrons off your hair and picks up a negative charge. Your hair, in turn, is left with a positive charge. You may even notice your hair has "static" and is standing out from your head.
2) Comb your hair with a plastic comb then use it to pick up small pieces of paper. The comb picks up electrons from your hair and becomes negatively charged. It uses this charge to attract the pieces of paper.
3) Rub your slippered feet on the carpet and then touch something metal like a door knob. The "shock" you feel is static electricity. You pick up electrons from the carpet and discharge them on to the door knob.
