Answer:
Change in Potential energy, pe = Final potential energy - Initial potential energy
Explanation:
∆p.e = Final p.e - Initial p.e
From the equation ∆p.e = (mgh) final - (mgh) initial
Answer:
0 (Zero)
Explanation:
Definition of work done states that ,
Work done on an object is the force applied on that object in the direction of Displacement of the object .
means that ,
W = F.dS (Dot product of Force and displacement)
When the wall is acted upon by the force of 20 N , Wall does not move ,
Thus , displacement of the wall is zero.
So, W = 20×0 = 0.
Thus, Work done on the wall is zero.
"decreasing the distance of the space shuttle from Earth"
F = Gm(1)m(2)/R²
where R is the distance between the 2 objects, as it decreases, the force increases.
Both the butterfly and the large car will have equal forces but in opposite direction.
<h3>
Newton's third law of motion</h3>
Newton's third law of motion states that action and reaction are equal and opposite. That is, the force exerted on an object is equal to the reaction experienced by the object.
Fa = - Fb
where;
- Fa is the force exerted by the large car
- Fb is the force of the butterfly
Thus, both the butterfly and the large car will have equal forces but in opposite direction.

The Public Health Act of 1848 was the result of advocacy by Edwin Chadwick, in response to the deplorable living conditions of poor urban laborers. Prior to the Act there were no uniform regulations regarding provisions for proper sanitation and clean water in cities where poor workers resided. As a result of the Act's passage, local governmental agencies were tasked with the responsibility for providing proper sanitation in urban communities in England and Wales.
