Answer:
Explanation:
V = J/C
V = 20/1
= 20 v
Option A is the correct answer
Answer:
the answer is 27
Explanation:
1/2mv^2 = KE
if mass is 3, and velocity is 3 (3^2 = 9)
then KE increases by a factor of 27
Answer:
Speed, S = 0.5m/s
Explanation:
Given the following data;
Distance = 30 meters
Time = 1 minute = 60 seconds
To find the speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;

Substituting into the above formula;

Speed, S = 0.5m/s
