47. Referring to Figure 2.18, estimate when Vega the fifth-brightest star in our sky (excluding the Sun), will once again be the northern pole star. 48. The apparent diameter of the Moon is approximately $1/20$ How long does it take the moon to move 3600? About how long does it take the Moon to move a distance equal to its own diameter across the sky (starfield)? 50. Earth has an average radius of 6,371 km. If you were standing on the Moon how much larger would Earth appear in the lunar sky than the Moon appears in our shy?

A 2500 kg car initially at rest rolls down a frictionless hill that is inclined at $37.2^{\circ }$ If the hill is 30.0 m long what is the velocity of the car as it reaches the base of the hill? $a=5.93m/s^{2}$ $v_{f}=[?]m/s$

The type of interference that comes from devices that radiate energy is known as __ electromagnetic interference conductive interference capacitive interference radio frequency interference

What is the specific heat capacity of water? the density of the water the amount of heat required to raise the temperature of a specific mass of water the ice required to cool a mass of water by one degree Celsius the temperature of the water

A radioactive substance decays in such a way that the amount of mass remaining after t days is given by the function $m(t)=11e^{-0.014t}$ where $m(t)$ is measured in kilograms. (a) Find the mass at time $t=0$ $\square $ kg (b) How much of the mass remains after 42 days? (Round your answer to one decimal place.) $\square $ kg

Which scenario represents the weakest force? (Assume particles in all scenarios are the same distance apart.) Protons and neutrons are held together inside the nucleus. Two particles are attracted to one another by static electricity. An unstable atom breaks down releasing two radioactive particles. Two rocks of equal mass fall to the ground at the same speed.
