A model shows what is inside of a cell and maybe how it functions. In a real cell all those characteristics are in the cell also. That is how a model of a atom is similar to the real one.
P.S. can u make me the braniest ....Need like 2 more brainest answers

Answer:
The fraction of the time is 38.67%.
Explanation:
Given that,
Energy = 4.68 KJ
Resistance = 60
Voltage =110 V
If the rate of heat energy supplied by the coil to the oil bath = Q
We need to calculate the power released by the resistor at voltage
Put the value into the formula
We need to calculate the fraction of the time
Put the value into the formula
The percentage of time is
Hence, The fraction of the time is 38.67%.
Answer:
W = 307.45 joules
Explanation:
the work done is defined as the product of force applied in the direction of displacement and the displacement.
Use the formula for work directly
(work) = (force) x (displacement)
Work is a scalar quantity and its SI unit is Joule.
W = F x d
F = 71.5 N
d = 4.30 m
W = 71.5 × 4.30
W = 307.45 joules
