Answer:
The temperature of the windings are 60.61 °C
Explanation:
Step 1: Data given
Resistance = 50 Ω
Temperature = 20.0 °C
After the motor has run for several hours the resistance rises to 58Ω.
Step 2: Calculate the new temperature
Formula: R = Rref(1 + α(T-Tref))
⇒with α = temperature coëfficiënt of Cupper at 20 °C = 0.00394/°C
⇒with Tref = reference temperature = 20°C
⇒with T = end temperature = TO BE DETERMINED
⇒with R = resistance at end temperature = 58Ω
⇒with Rref = resistance at reference temperature = 50 Ω
==> T = (R/Rref - 1)/α + Tref
T = (58/50) - 1 )/ 0.00394 + 20
T = 60.61 °C
The temperature of the windings are 60.61 °C
Answer:
<u>2600 cubic centimeters</u>
Explanation:
Volume of the edible fruit is equal to :
⇒ Volume (fruit) - Volume (seed)
⇒ 4/3π(3r)³ - 4/3πr³
⇒ 27 x 4/3πr³ - 4/3πr³
⇒ 100 (27 - 1)
<u>⇒ 2600 cubic centimeters</u>

Answer:
The strength of the magnetic field is 0.0842 mT
Explanation:
Given:
Velocity of rod

Length of rod
m
Induced emf across the rod
V
According to the faraday's law
We have a special case for moving rod in magnetic field.
Induced emf in moving rod is given by,

Where
strength of magnetic field


T
mT
Therefore, the strength of the magnetic field is 0.0842 mT
