An astronaut of 66.0kg mass is in preparation for launch to a distant planet. a) knowing that the gravitational acceleration on the surface of that planet is 0.33 of the gravitational acceleration g, what would be the weight of the astronaut on the planet? b) what is the mass of the astronaut on the planet? c) what would be the weight of the astronaut on the earth?

Part a)

Weight on surface of other planet = 213.4 N

Part b)

Mass of the Astronaut = 66.0 kg

Part c)

Weight of the Astronaut on Earth = 646.8 N

Explanation:

Part A)

Weight of the Astronaut on the surface of the planet is given as

here we will have

also we have

now we have

Part B)

Mass of the Astronaut will always remains the same

So it will be same at all positions and all planets

So its mass will be

m = 66.0 kg

Part C)

Weight of the Astronaut on Earth is given as

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
