In a diffraction grating experiment, λ = 590 nm and the numberof lines per mm in the grating is N = 100. How many yellow images of the slit can be seen through the grating?
The 5400m 1000-500mb thickness contour is often used as a proxy for the rain/snow line throughout much of the country. Calculate the mean virtual temperature of the layer for this thickness value.

An aluminum rod is 20.0 cm long at 20°C and has a mass of 350 g. If 12,500 J of energy is added to the rod by heat, what is the change in length of the rod
An elevator cable breaks when a 975 kg elevator is 24.5 m above the top of a huge spring (k = 8.00 x 10^4 N/m) at the bottom of the shaft. Calculate the amount the spring compresses
A curve of radius 52.6 m is banked so that a car of mass 1.6 Mg traveling with uniform speed 55 km/hr can round the curve without relying on friction to keep it from slipping on the surface
A grandfather's clock is calibrated at a temperature of 20 C. The pendulum is a thin brass rod with a heavy mass attached to the end. On a hot day, when the temperature is 30 C, does the clock run fast or slow? How much time does it gain or lose i..
The tackler holds onto the receiver, and the two move off together with a velocity of +1.6 m/s. The mass of the tackler is 115 kg. Assuming that momentum is conserved, find the mass of the receiver.
Proton one moves twice as fast as proton two. The magnitude of the magnetic field in which proton one is immersed is twice the magnitude of the magentic field in which proton two is immersed.
