Group of physics students are asked to demonstrate Ohm’s Law in parallel circuits. Using their knowledge of Ohm’s Law and the r
ules governing voltage, current, and resistance in series and parallel circuits they must set up an investigation using batteries, wires, three light bulbs of unknown resistance, a voltmeter, and an ammeter. Their task is to determine the resistance of each bulb. Given the equipment at hand, the groups determine that they will collect data to determine the voltage and current at each element in the circuit and use those values to calculate resistance. Four students offered their suggestions on which measurements must be taken to determine the resistance provided by each bulb. Which student’s suggestion below would provide enough evidence to be able to determine the value of each resistor?

Answer:
The net power needed to change the speed of the vehicle is 275,000 W
Explanation:
Given;
mass of the sport vehicle, m = 1600 kg
initial velocity of the vehicle, u = 15 m/s
final velocity of the vehicle, v = 40 m/s
time of motion, t = 4 s
The force needed to change the speed of the sport vehicle;
The net power needed to change the speed of the vehicle is calculated as;
Three complete orders on each side of the m=0 order can be produced in addition to the m=0 order.
The ruling separation is d=1/(470mm-1)
Diffraction lines occurs at an angle θ such that dsin=mλ,when λ is the wavelength and m is an integer.
Notice that for a given order,the line associated with a long wavelength is produced at a greater angle than the line associated with shorter wavelength.
we take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.
That is,find the greater integer value of m for which mλ<d.
since,d/λ
There are three complete orders on each side of the m=0 order.
The second and third orders overlap.
