Answer:
The time taken by to arrive on an area of
is
.
Explanation:
Given the intensity of the energy is
And the arriving energy is
Also, the area in which energy is being arriving is
Now, we will use relation between energy , intensity of energy
, area
and time
.
Where energy is in Joule, intensity is in , area is in
and time is in seconds.
The equation is
So, the time taken by to arrive on an area of
is
.
Answer:
The equal and opposite force is equal to the sum of any frictional force to the product of the mass of the wagon and the acceleration of the wagon
Explanation:
Newton's third law states that for every action, or force, there is an equal and opposite reaction
The equal and opposite force = The mass of the Wagon, m × The acceleration of the wagon, a + Any frictional force present,
Whereby the force with which the horse pulls the wagon = F, mathematically, we have;
The equal and opposite force = -F = m × a + .
