Work is the result when force ( F ) acts on object ( here: desk ) and moves it by some distance ( d ).
The formula is: W = F * d
Work = Force * Distance
We have : F = 20 N, d = 10 m
W= 20 N * 10 m = 200 J
Answer: The amount of work is 200 Joules.
Answer:
v = 54.2 m / s
Explanation:
Let's use energy conservation for this problem.
Starting point Higher
Em₀ = U = m g h
Final point. Lower
= K = ½ m v²
Em₀ = Em_{f}
m g h = ½ m v²
v² = 2gh
v = √ 2gh
Let's calculate
v = √ (2 9.8 150)
v = 54.2 m / s
The compound which can exabit the empirical formula of 1:3 is SO₃.
<h3 /><h3>What is empirical formula?</h3>
The simplest whole number ratio of atoms in a molecule is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfuric dioxide's empirical formula, S2O2, are two straightforward examples of this idea.
An empirical formula is a compound's chemical formula that only specifies the ratios of the elements it contains and not the precise number or arrangement of atoms. This would be the compound's element with the lowest whole number ratio.
