A student measured the mass of a rock to be 19.8 grams; the actual mass was 18.6 grams. What was the student's percent deviation?

An airplane begins its take-off run at A with zero velocity and a constant acceleration a. Knowing that it becomes airborne 30 s later at B with a take-off velocity of 270 km/h, determine (a) the acceleration a, (b) distance AB.

What topic in a biology textbook is directly related to physics

An empty capacitor is connected to a 12.0 V battery and charged up. The capacitor is then disconnected from the battery, and a slab of dielectric material (dielectric constant "k" = 2.8) is inserted between the plates.

Seems knows the mass of a basketball. What other information is needed to find the balls potential energy? A. The volume and height the ball reaches B. The volume and shape of the ball C. Acceleration due to gravity and the height the ball reaches D.

What is the number of protons and neutrons in the nucleus of an isotope

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.

What is: the fastest car the fastest animal the fastest human the fastest aeroplane

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
