Answer:
4×10⁴ seconds
Explanation:
Assuming you have a calculator on hand, inputting 300 ÷ .0081 give should give you 37037.0370...
In scientific notation, that number would be 3.70370370...×10⁴ and when taking into account the rounding rules for significant figures, the answer is 4×10⁴ seconds.
The latent heat of fusion, Lf. This is the heat per kilogram needed to make the change between the solid and liquid phases, as when water turns to ice or ice turns to water.
The latent heat of vaporization, Lv.This is the heat per kilogram needed to make the change between the liquid and gas phases, as when water boils or when steam condenses into water.
The latent heat of sublimation, Ls. This is the heat per kilogram needed to make the change between the solid and gas phases, as when dry ice evaporates.

Opposite to gravity is the normal force. ... The normalforce<span> is always equal in magnitude and opposite in direction to gravity. An </span>object<span> may also have friction</span>acting<span> on it. Friction is a </span>force<span> that occurs when two</span>objects<span> rub against each other, restricting or preventing motion.</span>
It's a measure of the acceleration
