A certain transverse wave is described byY(x,t)= B cos [ 2pi (x/L - t/T) ]where B= 5.30mm , L = 29.0cm , and = 3.10×10^?2 s.Determine the wave's amplitude.Determine the wave's wavelength.Determine the wave's frequency.Determine the wave's speed of propagation. Determine the wave's direction of propagation.
A researcher would like to perform an experiment in a zero magnetic field, which means that the field of the earth must be cancelled. What current is needed in the solenoid's wires
Waves on a 10 meter rope travel at 20 m/s. You shake the rope back and forth until you get a standing wave with a single antinode. find the wavelength and frequency of each standing wave
A baseball leaves the batter's bat at 30 degrees above horizontal. with what speed does the ball leave the bat
a golfer tees off on the fourth hole on a level golf course, giving the ball an initial speed of 42.0 m/s and an initial direction of 35 degrees above the horizontal. How far from the golfer does the ball land
When the temperature of a coin is raised by 83.1 C°, the coin's diameter increases by 2.60 x 10-5 m. If the original diameter is 1.61 x 10-2 m, find the coefficient of linear expansion.
The weight of the block on the table is 484 N and that of the hanging block is 165 N. Ignore all frictional effects, and assuming the pulley to be massless. Find the acceleration of the two blocks
An insulated Thermos contains 152 cm3 of hot coffee at 90 °C. You put a 12.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached?
The electric motor of a model train accelerates the train from rest to 0.540 m/s in 31.0 ms. Find the average power delivered to the train during its acceleration
Calculate the acceptance cone angle for a fiber optic cable that has an index of 1.70 for the fiber core and a 1.47 index for the cladding. What is the acceptance cone angle
