Answer:
24.21 m/s
Explanation:
x = Displacement in x direction = 55 m
y = Displacement in x direction = 0
= Height of the ball when the ball is kicked = 1 m
t = Time taken = 4.2 s
= Acceleration due to gravity = 
u = Initial velocity of ball
Displacement in x direction is given by
Displacement in y direction is given by
The ball should be kicked at an angle of
The initial speed of the ball is 24.21 m/s.
When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. The vaporization is the opposite process of condensation.
hope this helped <3
I think it would be by the change in speed
For example if light travels from air to water it will slow down causing it to travel at a different angle/direction
E force needed to accelerate a 68 kilogram-skier at a rate of

) and multiply them together
Answer:
D all of the above
Explanation:
electricity moves easily through all of them and none of them prevent the flow of electricity
