A 90-kg astronaut is stranded in space at a point 6.0 m from his spaceship, and he needs to get back in 4.0 min to control the s
Stella [2.4K]

Momentum = 0.5 * 4 = 2 
to conclude the man’s velocity after he throws the piece of equipment, divide this number by the man’s mass. 

v = 2/90 

This is about 0.0222 m/s. To know if he can move 6 meters at velocity in 4minutes, use the following equation. 

d = v * t, t = 4 * 60 = 240 s 
d = 2/90 * 240 = 5⅓ meters. 

This is ⅔ of a meter from the spaceship. To know the velocity that he must have to move 6 meter, use the same equation. 

6 = v * 240 
v = 6/240 
This is about 0.00416 m/s. 
His final momentum = 90 * 6/240 = 2.25 


To know the velocity of the package, divide this number by the mass of the package. 
v = 2.25/0.5 = 4.5 m/s

Light waves travel through space
VladimirAG [237]

C.even though there is almost no material in the interstellar medium, but do transfer  energy.

Explanation:

Light waves travels through space even though there is almost no material in the interstellar medium but do transfer energy.

A wave is any disturbance that transmits energy from one place to another.

  • Light is a form of wave which belongs to the electromagnetic spectrum.
  • They are propagated transverse to their source of energy.
  • These electromagnetic waves are special types of waves.
  • They are distinct because they do not require a material medium for their propagation unlike other waves.
  • In the interstellar medium. a vacuum is in place.
  • There are no matter that can be used for propagating waves.
  • Light waves still passes through because they do not require any medium to propagate.
