A projectile is fired from the edge of cliff , with initial velocity component of v0x=60 and v0y=175 . The projectile rises and then falls into sea. time of the flight of projectile is 40.0 s. what is the height of the cliff of the air resistance is negligible

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
