Answer:

Explanation:
From the question we are told that
Temp of first bolts
Temp of 2nd bolt 
Generally the equation showing the relationship between heat & temperature is given by

Generally heat released by the iron bolt = heat gained by the iron bolt
Generally solving mathematically





Therefore
is the final temperature inside the container
Explanation:
Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Before we can write down Newton’s second law as a simple equation giving the exact relationship of force, mass, and acceleration, we need to sharpen some ideas that have already been mentioned.
First, what do we mean by a change in motion? The answer is that a change in motion is equivalent to a change in velocity. A change in velocity means, by definition, that there is an acceleration. Newton’s first law says that a net external force causes a change in motion; thus, we see that a net external force causes acceleration.
Answer:
5 n
Explanation:
25 and 25 cancel each other out and 50-45 is 5
