Answer:
0.50
Explanation:
The maximum height is given by here h is the maximum height u is the initial velocity and is the angle of projection
So we can see from the relation that height is universally proportional to the gravity now in question it is given that the planet has the twice the surface gravity than the earth so the height will be half
Answer:
True
Explanation:
An electric field is a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
The water is already at its boiling point
, therefore we don't need additional heat to increase its temperature. Instead, we have to give the heat necessary to make it evaporate. The energy needed is equal to
where
m is the mass of the water
Lv is the latent heat of evaporation
The latent heat of evaporation of water is
, and the mass of this sample of water is
, therefore the heat needed to vaporize the water is
Answer:
The vertical distance that the ski jumper fell is 417.45 m.
Explanation:
Given;
initial horizontal velocity of the jumper, = 26 m/s
horizontal distance of the jumper, dx = 240 m
The time of the motion is given by;
dx = Vₓt
t = dx / Vₓ
t = 240 / 26
t = 9.23 s
The vertical distance traveled by the diver is given by;
initial vertical velocity, , = 0
Therefore, the vertical distance that the ski jumper fell is 417.45 m.
