On Earth, when Sally runs and jumps at an angle of 45° above the horizontal, her range is 3.3 m. What is her range on (a) the Moon where the gravitational acceleration is g/6, and (b) on Mars where the gravitational acceleration is 0.38g?

explanation:

newton's third law, for every action there is an equal and opposite reaction.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
