Answer:
Magnetic field lines form closed loops around current carrying straight wires.
Explanation:
Magnetic field lines is known to form closed loop (which also serves as a bar magnet) around current carrying conductor in a magnetic field. This direction of the loop around the conductor either clockwise or anticlockwise will determine the direction of current in the conductor.
This directions can be determined using the Maxwell cockscrew or clenched fist rule.
According to clenched fist rule which states if the conductor is grasp with the right hand, the curled finger will point in the direction of the magnetic field and the thumb will point in the direction of the current.
Note that the magnetic field lines around the conductor also behaves like a bar magnet.
The velocity of B after elastic collision is 3.45m/s
This type of collision is an elastic collision and we can use a formula to solve this problem.
<h3>Elastic Collision</h3>

The data given are;
- m1 = 281kg
- u1 = 2.82m/s
- m2 = 209kg
- u2 = -1.72m/s
- v1 = ?
Let's substitute the values into the equation.

From the calculation above, the final velocity of the car B after elastic collision is 3.45m/s.

There must be the presence of Deuterium to define stars. Deuterium fusion, commonly known as deuterium burning, is a nuclear fusion event in which a proton and a deuterium nucleus fuse to generate a helium-3 nucleus in stars and some substellar objects.
The main characteristic that distinguishes genuine stars from ordinary gas-filled balls, or brown dwarfs as they are frequently referred as, is the presence of nuclear fusion at the core. The temperatures are therefore high enough for nuclear fusion to take place, resulting in the fusion of protons to create help. Other items on the h r diagram that aren't necessarily actual stars would be things like white dwarfs and brown dwarfs. Other particles are accepted in the process, but that's kind of the general notion. Particularly for brown dwarfs, they don't actually have fusion taking place. You can plot a star as a point on the H-R diagram once you know its brightness and temperature (or color). With brighter stars positioned higher on the y-axis, plot luminosity.
