If each wire carries a current of 67 a in the same direction, what is the magnitude of the magnetic force per meter (in nm) exer
1 answer:
The magnitude of the magnetic force per meter (in nm) exerted on each wire is 3.74 * 10^-3 N/m or 3.74v 8 10 ^6 N/nm.
Magnetic force, enchantment or repulsion that arises between electrically charged debris due to their movement. it's miles the basic pressure accountable for such outcomes as the movement of electric cars and the appeal of magnets for iron.
Magnetic pressure is a compass, a motor, the magnets that keep stuff at the fridge, educate tracks, and new curler coasters. All transferring prices supply upward push to a magnetic subject and the costs that flow thru its regions, revel in a force.
Two items containing charge with the equal path of motion have a magnetic enchantment pressure between them. in addition, gadgets with price transferring in contrary instructions have a repulsive force between them. In our article on magnetic fields we found out how transferring rate surrounds itself with a magnetic field.
explanation is given in the image below.
Force per unit length between two wires ,
F/l = μοI₁I₂/2πd
= 4π * 10^-7 *67 *67 / 2π (24 * 10^-2)
= 2 * 10 ^-7 * 67 *67/24 *10 ^ -2
= 4489/12 * 10^-5
= 3.74 * 10 ^-3 N/m

Answer:
<em>Both kinetic energies are equal</em>
Explanation:
<u>Kinetic Energy </u>
Is the type of energy of an object due to its state of motion. It's proportional to the mass and the square of the speed.
The equation for the kinetic energy is:
Where:
m = mass of the object
v = speed of the object
The kinetic energy is expressed in Joules (J)
There are two cars:
Car (A) with mass ma=500 kg and speed va= 2 m/s
Car (B) with mass mb=20,000 gr and speed vb= 10 m/s
Calculate the kinetic energy of both cars:
To calculate the Kb, the mass must be expressed in kg:
mb=20,000/1,000 =20 Kg
Both kinetic energies are equal
