Physical science was once defined as "the science of the nonliving world." Explain why that definition is no longer sufficient.

A box is sliding down a ramp how many force vectors does the box have

A 70.0 kg skydiver falls towards the earth. The force due to air resistance is 1200 N. What is the acceleration of the skydiver?

An object with a mass of 62.5 kg accelerates 12.3 m/s2 when an unknown force is applied to it. What is the amount of the force?

Which statement best explains why nonpolar substances have low solubility in water? a) They are much larger than water. b) They are much denser than water. c) They have strong mutual attractions. d) They cannot form hydrogen bonds to water.

A 1.0 kg object moving at 4.5 m/s has a wavelength of: A) 1.5 * 10-34 m B) 2.9 * 10-33 m C) 7.4 * 10-35 m D) 1.4 * 10-34 m E) 2.9 * 10-34 m

An object is undergoing shm with period 0.900 s and amplitude 0.320 m. at t = 0 the object is at x = 0.320 m and is instantaneously at rest. calculate the time it takes the object to go (a) from x = 0.320 m to x = 0.160 m and (b) from x = 0.

Your friend states in a report that the average time required to circle a 1.0-mi track was 49.325 s. This was measured by timing 10 laps using a stopwatch with a precision of 0.01 s. Do you believe his results are reliable? Explain.

The forklift exerts a 300.0 N force on the box and moves it 15.0 m into the air. How much work does the forklift do? A. 500 J B. 1.50 * 10^3 J C. 4.50 * 10^3 J D. 0.00 J

Why the room gets hot even we open the door of refrigerator?
