Answer:
The answer to your question is Ep = 73.6 Joules
Explanation:
Data
mass = 2.5 kg
height = 3 m
gravity = 9,81 m/s²
Potential energy = ?
Potential energy is the energy stored in an object due to its position, the highest the object be, the highest the potential energy.
Formula
Pe = mgh
Substitution
Ep = (2.5)(9.81)(3)
Simplification and result
Ep = 73.6 Joules
Answer: The correct answer is-15 Volts.
Explanation-
Voltage of a battery can be defined as the difference in electric potential that lies between the positive and negative terminals of a battery.
It can be calculated using Ohm's law, which states that the electric potential difference between two points on a circuit is equal to the product of the current that flows between the two points (I) and the total resistance that sis present between the two points. It can be mathematically depicted as-
ΔV = I • R
Putting the value of 'I' and 'R', we get-
ΔV = 5 X 3
= 15 V
Answer:
Explanation:
Let magnetic force F acts towards right and the string makes an angle of θ with the vertical in equilibrium .Let T be tension in equilibrium
T cos θ = mg
T sin θ = F
Dividing
Tan θ = F / mg
F = mg Tanθ
= 51.5 x 9.8 x 10⁻³ x 26 / 20.8 Tanθ = 26 / 20.8 )
= 630.875 X 10⁻³ N
Answer:
