The equation of a transverse wave traveling in a string is given by y=A sin(k x??t). The tension in the string is 18.0 N, A = 1 mm, k = 22 rad/m, ? = 325 rad/s. What is the linear density of the string. I have the speed of the wave but i cant get the algebra to work out for some reason.
How much time elapses between first splash and second splash
What are changes in the object's momentum and velocity. How much work is done if the similar tension is directed parallel to the snow.
A 3.5 k and a 1.5 k resistor are connected in parallel and this combination is connected in series with a 1.8 k resistor. If each resistor is rated at 1/2 W, what is the highest voltage that can be applied across the whole network.
Using the data calculate the average speed of blood flow in the major arteries of the body which have a total cross-sectional area of about 2.0 cm2.
0.20g of hydrogen gas are held in a rigid container. The temperature of the gas is changed from 50 K to 80 K. How much heat is needed.
