The angle of reflection is the angle that the reflected ray makes with a line drawn perpendicular to the reflecting surface.
Most likely the answer would be John joined a group that studies astrological signs.
Explanation:
use the diagram^
horizontal velocity of the object nvr changes, it'll stay 50m/s till it hits the ground
initial vertical velocity = 0
to find the final vertical velocity, use the formula:
where u = 0m/s, a = 9.8m/s², and s = 2000m
solve for v.
for time taken to reach ground, use the formula:
where v = the value for v u calculated above, u = 0 m/s, a = 9.8m/s² and solve for t.
Upper Mantle produces the magma that causes seafloor spreading and volcanoes. Other term for that is the lithosphere. It is a solid, outer part of the Earth, extending depth of around 100 kilometers. it includes the crust and the brittle upper portion of the mantle. It is the coolest and most rigid part of Earth.
Answer:
An increase in frequency
Explanation:
A photon is an electromagnetic radiation without mass,as the energy of a photon is increased it frequency also increases.
Consider the equation below.
Energy = hf
We're h= is the Planck constant.
F is the frequency measured in Hertz from this a direct relationship exist between the energy and frequency
