Answer:
the answer is UV Radiation
Answer:
21s
Explanation:
Given parameters;
Radius = 10m
Speed or velocity = 3m/s
Unknown:
Period = ?
Solution:
To solve this problem, use the expression:
v =
r is the radius
T is the unknown
Input the parameters and solve for T;
3 =
62.84 = 3T
T = 21s
Any unit of acceleration must have the dimensions (form) of
(a unit of length) / (a unit of time)²
Potential energy due to gravity = Ep = mgh [symbols have their usual meaning ]
Evidently, HALVING the mass will make Ep , HALF its previous value. So, It will be halved.
