Answer:
Explanation:
Given the following data;
Mass = 35 kg
Velocity = 3 m/s
To find the kinetic energy of the child;
K.E = ½mv²
Another common household items is AA Alkaline batteries , I found these weigh approx 23 gram of them would have a mass of around 500 +/-5%. Never or unused , same mass
Answer is a.)
Given: Mass m = 70 Kg Height h = 10 m; g = 10 m/s²
Required. Gravitational Potential Energy or P.E
Formula: P.E = mgh
= (70 Kg)(10 m/s²)( 10 m)
P.E = 7,000 Kg.m²/s² or
P.E = 7,000 J
Answer:
a
When
b
When
Explanation:
From the question we are told that
The radius is R
The current is I
The distance from the center
Ampere's law is mathematically represented as
When
=>
But when
It’s the second one if I am correct
