Answer:
Light has the unique property that it can be described in physics as both a wave and as a stream of particles called photons
Explanation:
Considering the magnetic force is providing the centripetal force,
we get, mv^2/r = qvB
so, r = mv/qB
as the Kinetic energy, K of the particle is given by.5mv^2
so, v = sqrt(2K/m)
substituting the in radius equation,
<span>r = m*sqrt(2K/m)/qB
r = sqrt(2Km)/qB</span>
The frictional force acts upwards, so as to oppose the downward force of gravity. The reason that pressing against the wall harder makes the book stick more is because the reaction force from the wall increases and frictional force is directly proportional to reaction force.
Answer:
The pitch stays the same I think
Explanation:
Do length times width if u don't wanna do water displacement
