Water flows in a rectangular channel with a velocity of 2 m/s and depth of 4 m. Find the minimum specific energy of the flow.

If you touch a hot light bulb and get burned, that is an example of a. radiation b. convection c. conduction

Photons with the highest energy have the longest period

Aforce of 40n applied at the end of length 4m and diameter 2.00mm process and extension of 0.24mm, calculate the stress on the wire, strain in the wire and the young modulus for the material of the wire
