Answer:
Sound Waves
Explanation:
I remember doing a experiment where there was a bell in a vacuum. When the vacuum was turned on, over time, the bell was sound was drained out.
Answer:
DU = 20 Joules
Explanation:
Given the following data;
Heat absorbed, Q = 60J
Workdone, W = 40J
To find the internal energy;
We would use first law of thermodynamics given by the formula;
Change in internal energy (DU) = Q - W
where;
U is internal energy.
Q is the heat absorbed.
W is the work done.
Substituting into the equation, we have;
DU = 60 - 40
DU = 20 Joules
Answer:
Explanation:
Because you have no values on this graph, the only thing one can possibly state about this graph is that the object is experiencing a negative acceleration.
The white fur reflects all colors, so would appear green.
The black fur reflects no colors, so would still appear black.
