Answer:
1 wave-153 m/s
2 wave-162 m/s
3 wave-171 m/s
4 wave-175 m/s
5 wave-190 m/s
6 wave-202 m/s
7 wave-223 m/s
8 wave-238 m/s
avg speed-188 m/s
Explanation:
How close was your average speed to the calculation of the actual value for the speed of sound in m/s? Give 2 examples of errors that may have occurred during the lab that could have caused your value to be different than the value that you determined using the equation.
My average is pretty close to the actual value.
2 errors that may occur, are, not adding a temperature, and measuring in sm instead of m.

Given that Qc = 100J and QH = 250J, what is the work done?
Answer:
the work done is 150 J.
Explanation:
Given;
heat energy from the hot reservoir, QH = 250 J
heat energy from the cold reservoir, Qc = 100 J
Let the work done = W
The work done is calculated as follows;
W = QH - Qc
W = 250 J - 100 J
W = 150 J
Therefore, the work done is 150 J.

What does the force of gravity do for us?
Answer:
Earth's gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. Objects with more mass have more gravity.
Explanation:
A 41 g Ice cube at -21 C is dropped into a container of water at 0 C. How much water freezes onto the ice? The specific heat of ice is .5 cal/g C and it's heat of fusion of is 80 cal/g.
Answer:
The right solution is "5.38 grams".
Explanation:
The given values are:
Heat of fusion,
L = 80 cal/g
Mass of ice cube,
[tex]m_{ice} = 41 \ g[/tex]
Specific heat of ice,
[tex]C_{ice}=0.5 \ cal/g[/tex]
Let,
Gram of water freezes will be "m".
⇒ [tex]mL=m_{ice} C_{ice} (0+21)[/tex]
Or,
⇒ [tex]m=\frac{m_{ice} C_{ice} (0+21)}{L}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{41\times 0.5\times 21}{80}[/tex]
⇒ [tex]=\frac{430.5}{80}[/tex]
⇒ [tex]=5.38 \ grams[/tex]

What is the smallest height needed to make a wave?
A
6 feet
B
90 millimeters
C
20 millimeters
D
any height
the answer for this question is 6 feet
A wave can be made at any magnitude of amplitude. Therefore, the smallest height needed to make a wave is at any height. The correct answer is option D
A wave is a disturbance which travels through a medium transferring energy from one point to another without causing any permanent displacement of the medium.
The height needed by a wave is its amplitude. We can define amplitude as the maximum displacement of wave from original position.
A wave can be made at any magnitude of amplitude. Therefore, the smallest height needed to make a wave is at any height.
The correct answer is option D
