(8c1p14) Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons). Some rotate at a rate that is highly stable, sending out a radio beacon that sweeps briefly across Earth once with each rotation, like a light-house beacon. Pulsar PSR 1937 + 21 is an example, it rotates once every 1.55780644887275 ± 3 ms, where the trailing ±3 indicates the uncertainty in the last decimal place (it does not mean ±3 ms). How many times does it rotate in 3.50 days?
What is the mass of gasoline (? = 0.680 g/cm3) in a 94.6 L gasoline tank? (kg)
A 3.0 m long rigid beam with a mass of 120 kg is supported at each end. An 85 kg student stands 2.0 m from support 1. Explain by how much upward force does each support exert on the beam?
When the tire surface is rotating at the maximum speed of 12 m/s stone flies out of the tread. The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 1.8 N. suppose that only static friction supplies centripet..
The value of acceleration found in (b)iii, along with numerical values for the given quantities and your answer to (c), can be used to determine the rotational inertia of the pulley. The pulley is removed from its support and its rotational inerti..
