Answer: 2.7 m/s
Explanation:
Given the following :
Period (T) = 8.2 seconds
Radius = 3.5 m
The tangential speed is given as:
V = Radius × ω
ω = angular speed = (2 × pi) / T
ω = (2 × 22/7) / 8.2
ω = 6.2857142 / 8.2
ω = 0.7665505
Therefore, tangential speed (V) equals;
r × ω
3.5 × 0.7665505 = 2.6829268 m/s
2.7 m/s
When evaporation occurs liquid absorbs heat from the surroundings to get converted to its vapour form as a result, there is an overall decrease in the heat leading to cooling of the liquid.

<span>Force is needed to change an objects state of motion and it is always a part of a mutual action that involves another force. The force can be push or pull.</span>
A ball that moves when kicked <span>describes a force acting on an object.
</span><span>The force is a vector quantity, because it that needs both magnitude and direction in order to be defined.</span>
