B. it accelerates at a rate of 9.8m/s/
F = mass * acceleration
The 80kg hockey player was travelling at 5 m/s when he hit the wall.He stopped in .2 s, which means that he decelerated by 5m/s in .2 seconds.
This means this deceleration was 5 m / 0.2 s² = 25 m/s²
To calculate Force, multiply mass times acceleration
80kg times 25m/s² = 2,000 N
Answer: I think the last one, I am not sure but from what I learned what it looks like.
Explanation:
Answer:
B
Explanation:
I am pretty sure it is B as the speed is obviously constant but the velocity is not constant as it defines as the rate of speed AND DIRECTION meaning that it is not constant as it always changes direction. And angular velocity is constant.
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.
