Answer:
(you can use my exact words) The length and thickness would make it so that the electrons move differently than they would a shorter and thinner wire because with the wire being longer the electrons would have a longer trip and with the wire being thicker the electrons would be more spread out and move be able to move more freely
It does not hurt when an empty hangs lightly against a wall because the wall applies an
equal and opposite reaction force on you. In this case, Newton's third law is applicable.
Our hand hurts, when we are carrying a heavy load. This is because; the downward force acts or
our hand. This downward force depends on the weight of load. In this case, Newton's second law
is applicable.
Pls mark me brainliest answer
Every instrument has some uncertainty. No instrument is accurate. It depends on the least count of the instrument. The accuracy of a measurement is given by its uncertainty. The uncertainty is generally calculated as 50% of the least count of the instrument. Let us say, a clock can measure precisely till 1 s. it means it has a least count of 1 s. Then uncertainty of this clock would be 50% of 1 s= 0.5 s. Odometer is an instrument in a vehicle which measures and displays the total distance traveled. Let us say the odometer has a least count of 1 km. Then, its uncertainty would be = 50% of 1 km=0.5 km.
Answer:
A. Doubles.
Explanation:
In an electromagnetic device such as a generator, when a wire (conductor) moves through the magnetic field between the South and North poles of a magnet, an electromotive force (e.m.f) is usually induced across a wire
The mode of operation of a generator is that a metal core with copper tightly wound to it (conductor coil) rotates rapidly between the two (2) poles of a horseshoe magnet type. Thus when the conductor coil rotates rapidly, it cuts the magnetic field existing between the poles of the horseshoe magnet and then induces the flow of current.
When a high-resistance voltmeter is connected to an electric circuit, a deflection will arise due to the flow of electricity. Moving the magnet towards the coil of wire will cause the needle of the high-resistance voltmeter to move in one direction. Also, as the magnet is moved out from the coil of wire, the needle of the high-resistance voltmeter moves in the opposite direction.
In this scenario, a magnet is moved in and out of a coil of wire connected to a high-resistance voltmeter. If the number of coils doubles, the induced voltage doubles because the number of turns (voltage) in the primary winding is directly proportional to the number of turns (voltage) in the secondary winding.
Answer:
D
Explanation:
The car comes to a full stop meaning its initial velocity is 0 m/s.
Therefore, the final velocity of the car after 10 seconds is 50 meters per second or option D.
