A) A 3.00 gram lead bullet is moving at 180. m/s andenters a bag of sand and stops. By what amount does the temperature of the bullet change if all its kinetic energy becomes thermal energy.
B) A certain mass of hydrogen gas occupies a volume of 370. ml at 16.0'c and 150. kPa. Calculate the volume at-21'c and 420 kPa.
A series RC circuit is driven by an alternating voltage source at a frequency of 103 Hz. By what phase angle does the capacitor voltage lead (positive) or lag (negative) relative to the resistor voltage
A coating is applied to a lens to minimize reflections. The index of refraction of the coating is 1.50, and that of the lens is 1.48. If the coating is 177.5 nm thick, what wavelength is minimally reflected for normal incidence in the lowest order? n..

What is the density of Neon gas at standard temperature and pressure? The atomic mass of Neon is 20.18 atomic mass unit
Suppose an asteroid is found that appears to be heading directly toward Earth (using Earth's location at the time of discovery). It is 4.2 A.U. away (i.e., 4.2 times the Earth-Sun distance), and travelling through the Solar System with a speed of ..
At one instant a bicyclist is 43 m due east of a park's flagpole, going due south with a speed of 12 m/s. Then 22 s later, the cyclist is 43 m due north of the flagpole, going due east with a speed of 12 m/s.
