A.
According to the equation: v=λ*f
λ stands for wavelength. wavelength increases, the frequency will decrease. lower frequency deserves low energy.
The point on the graph is above or below the 3rd division on the x-axis. But that's all we know, since you've told us nothing about the motion.
Explanation:
Given that,
Mass of the particle, m = 4 kg
Speed of the particle, v = 2.5 m/s
The radius of the circle, r = 2 m
We need to find the angular momentum about the center of the circle. The formula for the angular momentum is given by :
Substitute all the values,
So, the angular momentum of the particle is 20 kg-m² s.
Answer:
1.Identify the atoms on each side,
2. Count the atoms on each side,
3.Use coefficients to increase the number of atoms on each side,
4.Check to make sure you have same number of each type of atom on each side
