On a hot dry day, the amount of water vapour present in atmosphere is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. Hence, a desert cooler cools better on a hot dry day.
Answer:
If he's 500 kg and 1 kg = 10 N then it would be 5,000 N
Explanation:
The surface area is unimportant and they'll use it to trick you.
The container that contains a greater volume of water will contain a greater mass of water.
The volume of the cube is given by:
V = s³
V = volume, s = side length
Given values:
s = 3m
Plug in and solve for V:
V = 3³
<em>V = 27m³</em>

The volume of the sphere is given by:
V = 4πr³/3
V = volume, r = radius
Given values:
r = 3m
Plug in and solve for V:
V = 4π3³/3
<em>V = 113m³</em>
<em />
The sphere contains more mass.

Explanation:
To find density you need mass and volume
to find mass use a digital balance and record it. Ex - 50g
to find the volume of the object
use a measuring cylinder and lets say you fill it up to 50cm³
then add the irregular object to the cylinder and record the new volume Ex - 54cm³
to find the volume of the object subract the final volume from the intial volume
54cm³-50cm³=4cm³
now that you have mass and volume use the equation D=M/V
Density = <u> Mass </u> = <u>50g </u> = 12.5g/cm³<u>
</u> Volume 4cm³
