They move faster and move farther apart
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.
<h2>Answer:</h2>
The option C is the correct answer.
Which is, "He varies the nitrogen and carbon dioxide levels in the air from one trial to the next".
<h3>Explanation:</h3>
The hypothesis of Malik was about the effect of increased oxygen level on the growth of the red-legged grasshoppers.
So the areas of his experiment should be the:
- Grasshopper type.
- High oxygen level.
- Rate of growth of grasshopper.
So all the given options are relevant to his experiment except the third one.
So varying the nitrogen and carbon dioxide level in air could not contribute in his experiment.

Dehydration? I think that’s it.
Answer:
Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy. which are called magnetic fields.
