Compute each parts of given question:
Question: A grandfather's clock is calibrated at a temperature of 21°C. Assume that the pendulum is a thin brass rod of negligible mass with a heavy bob attached to the end.
Part A: On a hot day, when the temperature is 32°C, does the clock run fast or slow?
Part B: How much does it gain or lose in a 24 h period?
I don't know how to get that answer for the above question. Please help! Thanks.
A proton (mass= 1.7×10-27 kg, charge= 1.6×10-19 C) travelling with speed 106 m/s enters a region of space containing a uniform magnetic field of 1.2 T. What is the time t required for the proton to re-emerge into the field-free region?
