Alarge crate is lifted vertically at constant speed by a rope attached to a helicopter. consider the following four forces that arise in this situation: (1) the weight of the helicopter, (2) the weight of the crate, (3) the force of the crate pulling on the earth, and (4) the force of the helicopter pulling on the rope. which one of the following relationships concerning the forces or their magnitudes is correct? a) the magnitude of force 4 is greater than that of force 2.b) the magnitude of force 4 is greater than that of force 1.c) forces 3 and 4 are equal in magnitude, but oppositely directed. d) forces 2 and 4 are equal in magnitude, but oppositely directed. e) the magnitude of force 1 is less than that of force 2.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

  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.
