Arock is thrown horizontally from the top of a radio tower lands 17.0 m from the base of the tower. if the speed at which the object was projected was 9.50 m/s, how high is the tower?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

How do i solve this physics problem?
