An advantage of electron microscopes compared to light microscopes is that electron microscopes are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes do not have higher resolution that

Suppose a car is moving in a straight line and steadily increases its speed. It moves from 35 km/h to 40 km/h the first second and from 40 km/h to 45 km/h the next second. What is the car acceleration?

Calculate the magnitude of the force the jumper must exert on the ground to produce an upward acceleration 4.00 times the acceleration due to gravity.

Q) Suppose, you are in a sporting event. You notice that everyone stands up when it's his turn, creating a wave that moves through the crowd and they sit back down again after a while.
