Q1. A proton moves perpendicular to a uniform magnetic field, B, at 1.6 multiplied by 107 m/s and experiences an acceleration of 1.8 multiplied by 1013 m/s2 in the positive x direction while its velocity is in the positive z direction. Find out the magnitude and direction of the field.
Q2. The front of her sleeper wet from teething, a baby rejoices in the day by crowing and bouncing up and down in her crib. Her mass is 14.0 kg, and the crib mattress can be modelled as a light spring with a force constant 4.70 kN/m. She learns to use the mattress as a trampoline -- losing contact with it for part of each cycle -- as her amplitude exceeds what value?
What is the instantaneous power, at a time of 0.00700 seconds, dissipated by a 200 ohm resistor in a resonant AC circuit powered by a generator with a 21.0 V highest potential difference operating at 5000 rad/s .
A father (m = 70 kg) and son (m = 45 kg) are standing facing each other on a frozen pond. The son pushes on the father and finds himself moving backward at 3 m/s after they have separated. How fast will the father be moving.
Calculate the coil's self-inductance. If the current decreases uniformly from 5.00 to 2.00 in 3.00, estimate the self-induced emf in the coil.
What is magnitude of the force that a concrete support exerts on the bridge at each end. The cloth exerts a friction force of 0.100 N on the mug and the cloth is pulled with a constant acceleration of 3.00 m/s.
