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.
Yes they are equivalent because 7x5=35 and 8x x 5=48x
Explanation:
Below is an attachment containing the solution.
It would be 24 candelas because since you have 6 lux and 4 meters all you do is multiply 6x4=24
Answer:
Option C) 14N
Explanation:
we know that
To find out the horizontal component of the force acting at X, multiply the tension in the string by the cosine of 30 degrees
so

Round to the nearest whole number
