The length of the rope Leo needs to purchase will be 45.3125 ft.
<h3 /><h3>How can you find out surface area ?</h3>
Surface area is calculated for common forms such as circles, triangles, parallelograms, rectangles, trapezoids, and so on.
When a form that isn't a standard figure appears, we slice it into standard shapes to get its area. The area of those component forms is then calculated and added together.
The surface area of the prism is,35 ft²
The length of the rope Leo needs to purchase;
L=5 ×9.0652
L=45.3125 ft
Hence,the length of the rope Leo needs to purchase will be 45.3125 ft.

<u>Answer</u>
1/4
<u>Explanation</u>
half life = 15 years
decay period = 30 years
The number of half-lives = 30 ÷ 15
= 2 half lives
1 ⇒(<em>after 1st half life</em>) ⇒ 1/2 ⇒ (<em>after 2nd half life</em>) ⇒ 1/4
The fraction that remained is 1/4.
Answer:
43,555 W
Explanation:
Since the speed is constant, this means that the force applied to lift the equipment is equal to the weight of the equipment. So we can write:
where
m = 1000 kg is the mass
is the acceleration due to gravity
So,
Then the work done in lifting the equipment is:
where
d = 200 m is the displacement of the equpment
Substituting,
Finally, the power used to lift the equipment is the ratio between the work done and time taken:
where
t = 45 s is the time taken
Solving,
Answer:
In the electric field, the like charges repel each other, and the unlike charges attract each other, whereas in a magnetic field the like poles repel each other and the unlike poles attract each other.
