Answer:
GPE = 199.92 Joules
Work = 199.92 Joules
Explanation:
A 5.1 kg beer cub weighs 49.98N
Mg = F
g = F/M
g = 49.98/5.1
g = 9.8 m/s²
GPE = mgh
GPE = 5.1 * 9.8 * 4
GPE = 199.92 Joules
The work done by the mother is equal to the GPE , because
Force*distance = work
Force = 49.98N
Distance = 4m
Work = 199.92 Joules

Explanation:
DRACO SEASON WITH THE BOOK BAG
A )voltage
(i.e differance in electricity field)
Answer:
141.13636 kg
Explanation:
= Mass of plane =
= Maximum mass that the baggage compartment can hold
= Mass of person = 75 kg
= Distance between pilot and center of gravity
= Distance between baggage and center of gravity
= Distance between center of gravity with pilot and without pilot
As moment of the system is conserved we have the relation
The maximum mass that the baggage compartment can hold is 141.13636 kg
Answer:
Current, I = 1.08 A
Explanation:
Given that,
Length of the copper wire, l = 12 cm = 0.12 m
Mass of the wire, m = 16 g = 0.016 kg
Magnetic field, B = 1.2 T
The magnetic field is oriented perpendicular to the wire. We need to find the current in the wire.
Magnetic force, F = BIL
Force of gravity, F' = mg
F' = F
I = 1.08 A
So, the current through the wire is 1.08 A. Hence, this is the required solution.
