Answer:



Explanation:
The Intensity
of the beam is

The diameter of the beam is 0.900mm; therefore, the area is


and since
, the intensity of the beam is


Now, the intensity
is related to
by the relation

solving for
we get

putting in the numbers we get:


The amplitude of magnetic field
is related to
by

putting in numerical values we get:


The average energy density of the laser light is



A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy
Answer:
A) 854.46 kPa
Explanation:
P₁ = initial pressure of the gas = 400 kPa
P₂ = final pressure of the gas = ?
T₁ = initial temperature of the gas = 110 K
T₂ = final temperature of the gas = 235 K
Using the equation

Inserting the values

P₂ = 854.46 kPa
Because its a vacuum, there's no air resistance, they will fall at same time
Applying gravity acceleration rule g=9.8m/s which is taken as 10m/s sometimes.
<span>Data organization is extremely important in science. One must be able to display data in a way that others can look at it and easily understand what's being said. This takes us to line charts, which are great for showing how something increases or decreases over an amount of time. Another example would be a pie chart which could show the percentages of different matter that makes up a full object.</span>
