Given:
heat generated by John's cooling system, 
= 45 W (1)
If ρ, A, and v corresponds to John's cooling system then let 
be the variables for Mike's system then:
Formula use:
Heat generated,
where,
= density
A = area
v = velocity
Solution:
for Mike's cooling system:
= 
⇒ = 
× A × 
= 4.513
A
Using eqn (1) in the above eqn, we get:
= 4.513 × 45 = 203.09 W
Answer:
a) 0.2399 mi³
b) 440.8 × 10³ Pounds
Explanation:
Given:
Volume of cumulus cloud, V = 1 km³
Liquid water content = 0.2 g/m³
Now,
a) 1 km = 
thus,
1 km³ = 
1 km³ = 0.2399 mi³
Hence, volume of cloud in cubic miles is 0.2399 mi³
b)
Liquid water content = 0.2 g/m³
Now,
1 Km = 1000 m
thus,
1 km³ = 1000³ m³
Therefore,
Liquid water content in 1 Km³ of cloud = 0.2 g/m³ × 1000³ m³
= 200 × 10⁶ gram
or
= 200 × 10³ Kg
also,
1 kilogram = 2.204 pounds
Therefore,
200 × 10³ Kg = 200 × 10³ × 2.204 pounds = 440.8 × 10³ Pounds
I would say d if I remember right I think that’s what I put and got right sorry if it’s wrong
If we use the sun as a distant object to calculate the convex lens's focal length, we obtain a number that is more closely related to the actual convex lens value.
We need to learn more about a convex lens's focal length in order to locate the solution.
<h3>Why, if we concentrate the sun, do we obtain a focal length that is closer to the correct value?</h3>
- An optical system's focal length is a measurement of how sharply the light converges or diverges.
- The distance between the convex lens's pole and its focus is known as its focal length.
- Convex lenses focus all of the rays from the distant object at their focal point to create a true image.
- We receive a crisper image if the object is farther away from the lens.
- Away from the focal point, an image will form if we concentrate on a neighboring window.
- To get the focal point on a distant tree, we must move the screen in the direction of the lens.
We can therefore draw the conclusion that if we use the sun as a distant object, we will obtain a value that is closer to the convex lens's actual value.

Since the specific heat of silver is given to be 0.057 calories/gram*C, obtaining the amount of calories should be as easy as multiplying the specific heat by the given values of the weight and the temperature to do unit cancellation. This is shown below:
(<span>0.057 calories/gram*C</span>)(10 grams)(20 C) = 11.4 calories
