To investigate absorption, Hector cuts two rectangles from five different-colored sheets of construction paper. He then staples three sides of each pair of rectangles to make a pocket and inserts a thermometer into each.
He takes the thermometers in the construction paper pockets outside, where it is clear and sunny. The initial temperature of each thermometer is 22°C. The image shows the thermometers after being outside for 15 minutes.
A thermometer in black paper reads 38 degrees Celsius, a thermometer in white paper reads 24 degrees Celsius, a thermometer in green paper reads 29 degrees Celsius, a thermometer in red paper reads 31 degrees Celsius, and a thermometer in blue paper reads 33 degrees Celsius.
Complete Hector's table by recording the final temperature and calculating the temperature change for each thermometer.

Answer:
The dimension of power is energy divided by the time or
Explanation:
Power =
We can derive Dimensions of Power from both formula.
Power = Force * Velocity
As,
Force = mass * acceleration
Therefore, Dimensions of
Force =
Since,
Velocity =
Now, Dimension of
Velocity =
We have Both Dimensions,Now we can derive Dimensions Of Power,
Power = Force * Velocity
Power =
Power =
<u>Answer:</u>
In an <u>inelastic collision</u> the kinetic energy is not conserved, but <u>the total momentum of the system is conserved</u>.
In other words; the Initial momentum is equal to the Final Momentum
:
Then:
<h2>
This means that after the collision the kinetic energy is transformed (dissipated) into another type of energy (caloric energy, for example); and there may be deformation in the blocks.
Therefore, the sentence that best describes this situation is:
<h2>The total momentum is zero. </h2>
