Answer:
The value is
Explanation:
From the question we are told that
The power is
The wavelength is
Gnerally the number of photon produced is mathematically represented as
Here is the Planck's constant with a value
c is the speed of light with value
So
=>
You've built quite a convoluted question there, Thelo.
If you wrote what you mean and I read it correctly, then the phrase
in the blank is "... the loss of energy to friction in the machine ...".
Friction is used to refer to forces that resist relative motion, in general,whereas viscosity refers specifically to resistive forces that occur between layers of a fluid when fluids attempt to flow. Fluid friction is the force that resists the movement of a solid object through a fluid(liquid or gas). Sky divers falling down through the sky experience a type of fluid frictioncalled air resistance.
Opposite to the direction of the velocity which led it to its current position.
Explanation:
The direction of momentum when a vertically oscillating block comes to the rest momentarily will be opposite to the direction of the velocity that it has just followed to reach reach its current position.
The direction of change in momentum at the bottom will be upwards and at the top will be downwards.
The change in momentum is mathematically defined as:
where:
mass of the block
final velocity of the block
initial velocity of the block
When the block comes to rest it is due to the result of continuously decreasing velocity.
