The correct option is A: the force exerted on the wall by the sledgehammer is - 1000 N
<h3>Newton's third law</h3>
Newton's third law of motion states that for every action or force, there is an equal but oppositely directed force.
<h3>Application of the newton's third law</h3>
Force with which the sledgehammer hits the wall = 1000 N
- From the Newton's third law, an equal but oppositely directed force is exerted on the sledgehammer by the wall.
Thus, the force exerted by the sledgehammer on the wall = -1000 N
- The negative sign indicates that the force acts in a direction opposite to that of the sledgehammer.
Thus, the correct option is A: the force exerted on the wall by the sledgehammer is - 1000 N

Force = [Mass x (velocity)^2]/Radius
Therefore,
The mass and the force are directly proportional.If you double the mass,the force will be doubled too.
A. Its centripetal force would <span>be doubled.</span>
Answer:A
Explanation:
In R-L circuit current is given by
![i=i_0\left [ 1-e^{\frac{-t}{L/R}}\right ]](https://tex.z-dn.net/?f=i%3Di_0%5Cleft%20%5B%201-e%5E%7B%5Cfrac%7B-t%7D%7BL%2FR%7D%7D%5Cright%20%5D)
where i=current at any time t

R=resistance
L=Inductance
at t=0
approaches to 1
therefore ![i=i_0\left [ 1-1\right ]](https://tex.z-dn.net/?f=i%3Di_0%5Cleft%20%5B%201-1%5Cright%20%5D)
i=0
when t approaches to
,
approaches to zero
thus 
thus we can say that initially circuit act as broken wire with zero current
and it increases exponentially with time and act as ordinary connecting wire
