How does the matter and energy in a system naturally change over time?

Calculate the acceleration of a car (in km/h•s) that can go from rest to 100 km/h in 10s

Determine the maximum theoretical speed that may be achieved over a distance of 66 m by a car starting from rest, knowing that the coefficient of static friction is 0.

Select the statement that correctly describes how light travels. Light cannot travel in a vacuum because it travels slower when the light source is moving. Light cannot travel in a vacuum because the light source is stationary.

A wave has a speed of 50 m/sec. If its frequency is 100 Hz, what is its wavelength? Dis placement vs. Position

I) sin^2 A sec^2 B + tan^2 B cos^2 A = sin^2A + tan²B

How does a message travel across the gap at a synapse?

Two speakers are 3.0 m apart and play identical tones of frequency 170 Hz. Sam stands directly in front of one speaker at a distance of 4.0 m. Is this a loud spot or a quiet spot? Assume that the speed of sound in air is 340 m/s.

Height formula in physics

What do we expect to happen to Earth's air temperature if the amount of energy from the sun that reaches the Earth's surface is reduced by half?

The gravitational force between two objects increases as mass A. decreases or distance decreases. B. decreases or distance increases. C. increases or distance decreases. D. increases or distance increases.
