Force of attraction between one atom and another within a compound formed by sharing of electrons or the loss and gain of electrons this is a bond
Answer:
heat energy
Explanation:
Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer.
the football player has speed
Answer:
30 C
Explanation:
Given:
Current flowing in the circuit (I) = 50 A
Start-up time (t) = 0.60 s
Now, we know that, charge drawn in through a cross sectional area of the circuit is given as:

Where, 'q' is the amount of charge drawn, 'I' is the current and 't' is the start-up time.
Now, plug in 50 A for 'I', 0.60 s for 't' and solve for 'q'. This gives,

Therefore, the amount of charge drawn in the circuit at the start-up of the compressor of an air conditioner is 30 C.
D) the mass of the star is the correct answer.
