It is the thermal energy transferred from a hot object to a cool object.
The following statement listed above is correct.
Answer: True.
Answer:
W = 68.6 N
Explanation:
Given that,
Force acting on a right side = 30 N
Mass of the object, m = 7 kg
The force of friction acting on the car = 3 N
We need to find the weight of the object.
The weight of an object is given by :
W = mg
Substitute all the values,
W = 7 × 9.8
W = 68.6 N
So, the weight of the object is 68.6 N.
The graph shows the production of Fe.
You can see from the graph that it increases rapidly and then slowly increases.
The answer is (A).
Cheers.
