Answer:
88.3
Explanation:
Emf in a rotating coil is given by rate of change of flux:
E= dФ/dt=(NABcos∅)/ dt
N: number of turns in the coil= 80
A: area of the coil= 0.25×0.40= 0.1
B: magnetic field strength= 1.1
Ф: angle of rotation= 90- 37= 53
dt= 0.06s
E= (80 × 0.4× 0.25×1.10 × cos53)/0.06= 88.3V

Answer:
P = 1235.7646 W
Explanation:
Given data:
height of raised sewage = 5.49 m
rate of sewage =1.89*10^6 lt/day
density of sewage = 1.050 kg/m^3
power is written as
work = m g h
h -height
mass lifted per day 
= 1984500 kg
time = 24 hours* 3600 seconds per hour
power
P = 1235.7646 W
Answer: option B: The resistor has a tolerance of 20%.
Explanation:
Resistors are color coded to identify their value and function. For a 3- Band resistor, reading from the left, first band denotes first digit, second band depicts second digit and third color depicts the multiplier. The absence of fourth band means the resistor has tolerance 20%.
Hence, the correct answer is option B. The resistor has a tolerance of 20%.
The answer is shown below:
"The diurnal motion" of the stars is defined as the apparent daily motion of stars around the Earth. The cause for this "apparent motion of stars" was proposed by Heraclides (who was a Greek philosopher and astronomer). He afirmed that this was created by the Earth's rotation on its axis, which is completed in 23 hours, 56 minutes and 4.09 seconds.
