<span>The larger the current flowing in a wire, the stronger the magnetic field
is that surrounds the wire.
That's why, if you want to make an electromagnet stronger, one way to
do it is to add another battery. By increasing the voltage, you'll increase
the current flowing in the coils of wire, and the electromagnet will be stronger.</span>
Hope this provides some answers
Answer:
The answer to this question is acceleration or as scientist say velocity.
Explanation: We know that when you drive a car the acceleration is effected by the amount of speed you add when you press the gas,so you are accelerating the car faster.
Answer:
0.06 A
Explanation:
We have given mass =0.954 kg
velocity =1.27 m/sec
efficiency =0.361 the output kinetic energy of the motor 
Efficiency =0.361
so input to the motor = output/efficiency
so input to the motor = 
we know that
where E is energy and T is time so 
We know that power P=VI we have given V=4.5 VOLT
So current 
Answer:
D. A 10 kg rock at 15°C
Explanation:
Thermal energy is heat energy, meaning that the hotter rocks will have more energy.
The heavier/larger rocks can store more energy.
So if we combine the largest two variables, we get a 10kg rock at 15°C.
