1st Law Of Motion: An object will often remain at rest or continue moving unless acted upon.
2nd Law Of Motion: Force is equal to mass times acceleration
3rd Law Of Motion: For every action there is an equal or opposite reaction
Answer:
434.0 V/m
Explanation:
The power output of the laser is:
while the radius of the beam is
so the cross-sectional area is
So the intensity of the laser beam is
The intensity of a laser beam is related to the magnitude of the electric field by
where
c is the speed of light
is the vacuum permittivity
Solving the formula for E, we find
In physics, the rate of power in Watts could be determined by multiplying the voltage in volts, by the current in Amperes. In equation, that would be
P = IV
Substituting the values into the equation,
60 W = I*12V
I = 60/12
I = 5 Amperes
Therefore, a current of 5 Amperes is passing through the yellow wire.
As an egg falls towards the floor, it begins to travel faster and faster. When it slams into the floor, the egg is stopped almost immediately. This force of the floor against the eggshell is too large, so it breaks.
