The electrical energy consumed by a toaster is 0.033 Kwh.
<u>Explanation</u>:
The power utilized by the toaster is 400 W.
The toaster is operated for 5 Minutes.
We know that,
Substitute the values in the above formula to obtain electrical energy,
Electrical energy = 0.4 × 0.083
Electrical energy is 0.033 Kwh.
Answer:
Induced current,
Explanation:
Given that,
Area of cross section of the wire,
Time, t = 2.2 s
Initial magnetic field,
Final magnetic field,
Resistance of the coil, R = 8 ohms
The expression for the induced emf is given by :
= magnetic flux
So, the induced emf in the loop is 0.023 volts. The induced current can be calculated using Ohm's law as :
So, the magnitude of the induced current in the loop of wire is . Hence, this is the required solution.

Answer:
Explanation:
Given
mass of satellite
orbital radius
mass of Earth
Minimum amount of Energy to move Satellite from its orbit to an infinite distance is sum of Potential Energy + Kinetic Energy of Satellite
Where
i.e. Energy is required to provide to move Satellite out of its orbit
The coefficient of expansion is 13 * 10^-6 m per meter length.per oK
The temperature difference = 42 - - 8 = 50 oC
delta T = (42 + 273) - (-8 + 273) = 50 oK
delta L = L * 13* 10^6 m/oK
oK = 50 oK delta L = 19.5 cm = 19.5 cm [1m / 100 cm] = 0.195m
So we need to find the length and it is computed by:
0.195= L * 13 * 10^-6 * 50 L = 0.195 / (13*10^-6*50) L = 300 m
