Two concurrent forces are represented in the diagram below. What is the magnitude of the vector sum of the two forces, in N to the nearest tenth?

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
