First, report this to your instructor. Small cuts should be cleaned
and checked for broken glass. Bandages and dressings are available in the
First-Aid Kit found in the laboratory. If bleeding is not stopping, apply
pressure to the wound or affected area. Any treatment outside emergency first
aid will be referred to the student infirmary. Severe emergencies will be
referred to the Hospital emergency room.
To solve this problem it is necessary to apply the concepts related to entropy. Entropy can be defined as the change between heat energy and body temperature. For this case we will analyze the entropy in the cold body and later in the hot body. From there we will find the entropy difference
Entropy can be defined as,
Here,
Q = Heat Flow
T = Temperature
The entropy of the hot reservoir goes down by
The entropy of the "cool" reservoir increases by
As expected, entropy increased in this process; the entropy lost by the hot side was less than the entropy gained by the cool side.
The answer will be
(1) correct
(2) correct
(3) the force of the soccer ball on the net
(4) Will not change
Hope this help
A would be the best answer to this question
Answer:
Explanation:
The resistance of a conductor is directly proportional to its length and is inversely proportional to its cross-sectional area, this dependence is given by:
is the material's resistance, L is the legth and A is the cross-sectional area.
For the first and second coils, we have:
For the third and fourth coils, we have:
