An electron is moving through a magnetic field whose magnitude is 9.21 × 10^-4 t. the electron experiences only a magnetic force and has an acceleration of magnitude 2.30 × 10^14 m/s^2. at a certain instant, it has a speed of 7.69 × 10^6 m/s. determine the angle (less than 90°) between the electron's velocity and the magnetic field.

The specific heat of silver is 0.057 calories/gram°c. if 10.0 grams of silver were heated and the temperature of the sample changed by 20.0°c, how many calories of heat energy were absorbed by the sample?

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
