PLEASE HELP ME!! If the acceleration of gravity is 9.8 m/s?, then that means an object falling at
90° will be traveling 9.8 m/s after 1 second, 19.6 m/s after 2 seconds, and so on.
Use the data values in your table to sketch a rough graph of velocity versus time
for the 10° angle and another for the 40° angle. What value do the slopes of these
graphs represent? Which graph has the greater slope? Why?

Which is not a characteristic of a heat pump? a. it is used in air conditioners. b. it uses a refrigerant. c. it requires no work. d. it reverses the normal flow of thermal energy.

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates
