Hi there!
We can use Newton's Second Law:
ΣF = Net force (N)
m = mass (kg)
a = acceleration (m/s²)
We can rearrange the equation to solve for the acceleration.
Answer:
The existance of dark energy was suggested to help explain measurements, using Type Ia supernovae as distance indicators, that the expansion of the universe is speeding up and its acceleration requires a source of energy. Scientists suggested that It may be a new form of energy for which there is not yet a theoretical explanation. quantum mechanics predict that it may be the vacuum energy associated with "empty" space itself.
Polarization of light is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.
<h3>What is polarization of light?</h3>
The question is unclear but I will try to explain what is meant by polarization of light. We know that light is an electromagetic wave and vibrates in all directions.
The polarization of light enables light to vibrate in a specified direction. This is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.

The answer that would best complete the given sentence above is cubic meter. The standard unit for measuring volume is the cubic meter (m^3). Volume is the quantity or the measurement of the amount of space that can be or is being occupied by matter. The metric unit for volume includes "liters" and "milliliters".
<h2>Answer:</h2>
False:
<h2>Explanation:</h2>
Jet streams are like rivers of wind high above in the atmosphere which have a huge influence on climate because they can push air masses and affect weather patterns. Jet streams travel in the tropopause which is the boundary between the turbulent troposphere and the calm, cold stratosphere. So we can say that jet streams lie in stratosphere and not in mesosphere.
