Answer: The correct option is that the axe handle applying a force to the person's hand.
Explanation:
This reaction force is due to Newton's third law of motion. This law states that for every action there is equal and opposite reaction to it. This implies that when a force is being exerted on a surface, the surface must exert a force that is equal and opposite in direction to the exerting force. This law represents a certain symmetry in nature that forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
A typical example of Newton's third law includes:
--> When you hit a tree with an axe: with your hand you exert a force on the tree with the intention to cut it down(action force). The same force you excreted on the tree would be felt in your hands (reaction force).
--> when air rushes out of a balloon: when air escapes for a balloon, the opposite reaction is that the balloon flies up.
Answer:
Correct answer: F = 5.075 N
Explanation:
The formula for Newton's Second Law is
F = m · a = 0.145 · 35 = 5.075 N

Solve to magnetic field
The charge and mass of the proton are:
,
Replacing numeric
There is only one pressure this situation would be a "constant pressure" process
Answer:
2.1406 × m/sec
Explanation:
we know that energy is always conserved
so from the law of energy conservation
here V is the potential difference
we know that mass of proton = 1.67× kg
we have given speed =50000m/sec
so potential difference
now mass of electron =9.11×
so for electron
so the velocity of electron will be 2.1406× m/sec
