Answer:
I think the Bulb No. 2 will stop emitting light if the bulb No. 1 burns out.
Answer:
Explanation:
A motor converts electrical energy to mechanical energy. A current carrying coil is placed between electromagnets. A magnetic force is exerted on the coil which makes it rotate. The direction of current changes twice during the rotation of the coil. An outside source of electric current is used.
Thus, the wrong statement is D. It converts mechanical energy into electrical energy. It is the generator which converts mechanical energy into electrical energy.
When practicing an oral presentation, you can prepare by writing a draft and practice reading aloud what you are going to say before your oral presentation.
Answer:
A symbol for a battery.
Explanation:
A battery, because every sinlge circuit AC or DC must have a source of energy, to supply it to every single device that is part of the circuit.
The voltage is defined by the Ohm's law and it is equal to the product of the current by the resistance.
Answer:
e) Be four times greater
Explanation:
Here we have to use Newton's gravitational law that relates the gravitational force between two objects with their masses (
& 
) and the distance between them (
) in the next way:
(2)
Now if distance between asteroids is halved:
Note that 
because (1) is F so:
It's four times greater!
