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

Answer:
537 N
Explanation:
The force due to gravity of a planet is:
F = GMm / r²
where G is the universal gravitational constant
M is the mass of the planet
m is the mass of the object
and r is the distance between the object and the center of the planet
On Earth, you weigh 716 N, so:
716 N = GMm / r²
On planet X:
F = G (3M) m / (2r)²
F = 3/4 GMm / r²
F = 3/4 (716 N)
F = 537 N
Its false I got It right .
The answer is Conduction: the process of heat is directly transmitted through a substance when there is a difference in temperature.

Explanation:
The legend of King Arthur is well-known in literature. Based on Unsolved Mysteries of History, there is little to suggest it is true. Do you think it is important for people to believe in legends like King Arthur even if there is little evidence to support them? Why or why not? Write a short (3 paragraphs) explanatory essay stating your opinion. Justify your opinion and conclusions with relevant textual evidence (quotes or paraphrased ideas from sources) and background knowledge. Remember to use relevant vocabulary from the text in your essay.l
