The answer for the following question is explained below.
- <u><em>Therefore the work done is 130 kilo Joules.</em></u>
Explanation:
Work:
A force causing the movement or displacement of an object.
Given:
mass of the person (m) = 65 kg
height of the cliff (h) = 2000 m
To calculate:
work done (W)
We know;
According to the formula:
<u>W = m × g × h</u>
Where;
m represents mass of the person
g represents the acceleration due to gravity
where the value of g is;
<u> g = 10 m/ s²</u>
h represents the height of the cliff
From the above formula;
W = 65 × 10 × 2000
W = 130,000 J
W = 130 Kilo Joules
<u><em>Therefore the work done is 130 kilo Joules.</em></u>
4) They have non-moving magnetic fields.
Answer:
100 m
Explanation:
if the car travels at 10 m/s for 10 seconds it would travel 100 m during that time.
10*10 = 100
Answer:
correct order 2,4,3,1
Explanation: correct on edge
Answer:
<h2>
The number of tree is 2</h2>
Explanation:
the diagonal of the rectangular plot of land can be found using Pythagoras theorem (the diagonal is the hypotenuse)
Given
length of land x= 48m
width of land y= 20m
digonal z= ?
substituting the values of x and y into the equation we can solve for z
The diagonal is 52m
Hence since the interval = 22m the number if treee is
The number of trees must be whole numbers , the number of tree is 2
