Answer:
Normal force of 10,000N
Explanation:
From the question, the weight the car exerts on the pavement is 10,000N.
The pavement exerts upward and perpendicular contact force called normal force on the car to support its weight. Also, the normal force is equal and opposite to the weigh of the car.
Hence the pavement exerts normal force of 10,000N back on the car to prevent it from passing through it.
PRE stands for progressive resistance exercises. This refers to exercises which progressively increase the load applied to the muscles. Here are some guidelines for safe PRE:
1. Do the exercises slowly, surely and smoothly. Avoid doing abrupt movements so as not to strain your muscles.
2. When doing the exercises, make your you execute them properly. For example, when lifting weights, lift them all the way up and all the way down.
3. Use spotters for support and to avoid accidents.
Yes its D. Molecules is the answer because A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
Answer:
Force between two charges is given as 1.296 N
Explanation:
As we know that the two charges will attract or repel each other when they are placed near to each other
Here we know that electrostatic force is given as
here we have
distance between two charges is given as
r = 0.50 m
so we have
