1. A physics student reads a problem and is able to write three independent equations that relate the known variables and four unknown variables. Is it possible for him to find a unique solution to the
problem?
A. yes
B. no

When someone slams her books on a table the kinect energy is transferred into vibrations that travel to your ears as sound waves which statement describes the movement of those waves

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
