work done by gravitational force = mass × g × height
= mgh
= 5 × 10 × 8 N
<h3>= 400 N</h3>
Answer:
Explanation:
The collision is inelastic and can be described by the Principle of Momentum Conservation:
The speed after the collision is:
Answer:
θ = 45º
Explanation:
The light that falls on the second polarized is polarized, therefore it is governed by the law of Maluz
I = I₀ cos² θ
in the problem they ask us
I = ½ I₀
let's look for the angles
½ I₀ = I₀ cos² θ
cos θ = √ ½ = 0.707
θ = cos 0.707
θ = 45º
Answer:
Shoe size is continuous because it is a gradual change that changes over time, but stops when our feet is at its full length
