Answer:
The current in the heater is 12.5 A
Explanation:
It is given that,
Power of electric heater, P₁ = 1400 W
Power of toaster, P₂ = 1150 W
Power of electric grill, P₃ = 1560 W
All three appliances are connected in parallel across a 112 V emf source. We need to find the current in the heater. We know that in parallel combination of resistors the current flowing in every branch of resistor divides while the voltage is same.
Electric power, 



So, the current in the heater is 12.5 A. Hence, this is the required solution.
For the rest 3 km
Bholu need to run in 5 minutes so
He need to 3 × 1000 / 5 × 60 m/s
3000/ 300 = 10 m/s
So , his speed should be 1 m/s to reach in 5 minute

Answer:
<h3>The 28 loops wound on the square armature</h3>
Explanation:
Peak output voltage
V
Area of square armature 
Magnetic field
T
Angular frequency 
According to the law of electromagnetic induction,

Where
number of loops of wire.

≅ 28
Thus, 28 loops of wire should be wound on the square armature.
