C) it cleans the air

A transverse wave on a string is modeled with the wave function y (x, t) = (0.20 cm) sin (2.00 m^-1 x - 3.00 s^-1 t + pi/16) What is the height of the string with respect to the equilibrium position at a position x = 4.00m and a time t = 10.00 s a.

What's the relationship between work done and force applied

What Is Coulomb's Force?

The height h (in feet) of an object shot into the air from a tall building is given by the function h (t) = 650 + 80t - 16t2, where t is the time elapsed in seconds. (a) Write a formula for the velocity of the object as a function of time t.

Which is a valid velocity reading for an object? A) 45 m/s B) 45 m/s north C) 0 m/s south D) 0 m/s

A baseball player is dashing toward home plate with a speed of 3.8 m/s when she decides to hit the dirt. She slides for 1.3 s, just reaching the plate as she stops (safe, of course).

The water that powers the generators enters and leaves the system at a low speed (thus we can neglect its change of kinetic energy) and loses 160 m of altitude during the process.

Why is gravitational potential energy negative?

Imagine an elevator crowded with too many passengers for such a small space. This situation would be a good analogy for a substance with what property
