A wall, acted upon by a force of 20 N, does not move. The work done on the wall in this process is
jenyasd209 [6]

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.

A rare butterfly (0.01 kg) is slowly flapping its wings and moving across a road. An unsuspecting driver in a large car (1000 kg
aliya0001 [1]

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.

Which of the following statements might be used to defend the Act of 1848​
d1i1m1o1n [39]
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.
