The current in the wire has created a magnetic field with its north pole at the top of the rod. A magnetic field influences electric currents.
<h3>What is a magnetic field?</h3>
A magnetic field is a type of field that influences the position and direction of the electric current.
The magnetic field also refers to the one where magnetic forces act to shape an electrical current.
The only material and/or body capable of altering an electrical current in a magnetic field is the presence of another magnetic field.

In a circuit, if the resistors were decreased by a factor of 1,000, it is true that the current would increase by a factor of 1,000, according to Ohm's Law.
<h3>What is Ohm's Law?</h3><h3 />
It is a law in electricity that posits that the voltage that goes through a conductor is directly proportional to the current.
<h3>How does Ohm'slaw explain the change in current?</h3>
One formula in Ohm's law is:
Voltage = Current x Resistance
If the resistance were to decrease by a factor of 1,000, the current would have to increase by a factor of 1,000 as well in order to give the same voltage.

Answer:
Ionosphere
Explanation:
The thermosphere reaches 600 kilometres just above mesosphere and begins immediately above the mesosphere. This layer is where the aurora and satellites appear.
The ionosphere is the comprehensive career of the mesosphere because most of the thermosphere, located 80–400 kilometres just above ground atmosphere.
Auroras — magnificent flowing streaks of light seen in the night sky – appear in this location.
The answer is d) The 1.5 kg ball because it has more momentum.
Momentum = Impulse = Mass + Velocity
= 2 * 10 = 20 kg*m/s
= 1.5 * 20 = 30 kg*m/s
hence the 1.5 kg ball has greater momentum and impulse.

Answer:
There are 5847.95 lines per cm for the grating.
Explanation:
Given that,
Wavelength of mercury line,
Angle in the third order spectrum,
Using the grating equation, we get :
Here, m = 3
Let there are N lines for the grating. So,
So, there are 5847.95 lines per cm for the grating.
