I need help with these questions :
(see image)

Initial velocity =

Height = H = 100 m

Acceleration due to gravity = g = 10 m/s^2

Time of flight = ?

Angle of projection= θ(theta) = ?

Range attained = ?

A) The Relation between Height and Total time of flight is given by,

B) Total time of flight is given by,

Square root on both sides,

C) The range attained is given by,

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

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

hope this ! this is not copied! search it up, it's free of plagiarism!
