Perseverance, good mind set, and work ethic
Answer:
W = 12.96 J
Explanation:
The force acting in the direction of motion of the sand paper is the frictional force. So, we first calculate the frictional force:
F = μR
where,
F = Friction Force = ?
μ = 0.92
R = Normal Force = 2.6 N
Therefore,
F = (0.92)(2.6 N)
F = 2.4 N
Now, the displacement is given as:
d = (0.12 m)(45)
d = 5.4 m
So, the work done will be:
W = F d
W = (2.4 N)(5.4 m)
<u>W = 12.96 J</u>
Answer:12,352 cal
Explanation:
Given
to change 16 gm ice at 
First we need to take ice to
then change its state to water and then raises water temperature from 0 to
.
After it change water phase to steam and then raise its temperature to 
+
Q=12,352 cal
D, it depends. For water, the solubility increases as it get hotter, up to 100 degrees, but in some cases, liquids behave the opposite way.
I think it is a insulator because plastic is a poor conductor of heat
