Along jumper can jump a distance of 7.4 m when he takes off at an angle of 45° with respect to the horizontal. assuming he can jump with the same initial speed at all angles, how much distance does he lose (in m) by taking off at 429?

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
