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.

-- If the force is applied in the <em>same direction</em> as the object is moving, then the object's momentum in that direction will <em>increase</em>.
-- If the force is applied in the direction <em>OPPOSITE </em>to the way the object is moving, then the object's momentum will <em>decrease</em>.
-- In either case, the CHANGE in the object's momentum will be
(strength of the force) x (length of time the force is applied) .
This quantity is also called "impulse".
Answer:
83 protons 126 neutrons. Bismuth Atom
Explanation:
The largest number of stable nuclei which could ever exist is the bismuth atom. A nuclei which is higher than that 83 protons is unstable and the nucleus will eventually breakdown through radioactivity.
