Answer:
D. A record of all the physical activity you complete in one week.
Explanation:
A "Fitness Log" allows you to keep track of your workout or exercise. Therefore, it is <em><u>a record of the different workout you've managed to complete within a time frame</u></em>. It gives you several information such as the<em> type of workout you've completed, its duration and the time of the day it was performed</em>. This makes a person motivated to exercise because he can see his progress. He may also include <em>his mood before and after workout</em> in order to become more mindful in exercising and many other things.
When the object slides across the rough surface some of its potential energy will be lost to friction.
<h3>Conservation of mechanical energy</h3>
The law of conservation of mechanical energy states that the total mechanical energy of an isolated system is always constant.
M.A = P.E + K.E
When the object slides across the rough surface, some of the potential energy of the object will be converted into kinetic energy while the remaining potential energy will be converted into thermal energy due to frictional force of the rough surface.
P.E = K.E + thermal energy

Answer:
A, 30V
Explanation:
First combine all resistors to an equivalent resistor. Since they are in series, the equivalent resistance is the sum of all resistor
Req = 20 + 40 + 60 = 120Ω
Using Ohm's law, find the current in the circuit
V = I * R
I = V / R
I = 60V / 120Ω
I = 0.5 A
Now the potential drop across the resistor R3 is the current times R3 resistance, therefore:
Vdrop = 0.5A * 60Ω = 30V
So the potential drop across resistor R3 is 30 V
