A block of mass 8 m can move without friction
nekit [7.7K]

Answer:

Let M1 = 8 kg and M2 = 34 kg

F = M a = (M1 + M2) a

F = M2 g     the net force accelerating the system

M2 g = (M1 + M2) a

a = M2 / (M1 + M2) g = 34 / (42) g = .81 g = 7.9 m/s^2

9. Luke is an astronaut that moves his position in the space shuttle by climbing a
BartSMP [9]

Explanation:

Remember that power is defined as how much Work is done per unit of time.

P = \frac{dW}{dt}

Work is defined as the amount of force applied across a certain distance.  

W = F*d

Since in both cases of climbing the ladder (on Earth and the moon), Luke coveres the same amount of <em>distance </em>in the same amount of <em>time</em>, we are only left with one difference between the two cases - gravity.

If you were to carry your backpack on the moon with the same load of text books, it would take less force to pick it up on the moon. Therefore, Luke expends less effort on the environment with less gravity - the moon.

To find the difference factor - you would want to divid the gravitational contants between earth and the moon.

As you drive away from a radio transmitter, the radio signal you receive from the station is shifted to longer wavelengths.
mylen [45]

Answer:

True

Explanation:

{Apparent}.wavelength = (True.wavelength)(1 +\frac{recession.velocity}{wave.speed})

As one drive away from the radio station, the recession velocity increases and causes the apparent wavelength to increase accordingly, which in turn causes the True wavelength received from the radio station to increase as well because of their direct relationship as shown in the equation above.
