Answer:
The magnitude of magnetic field decreases in comparison to previous case.
Explanation:
Let current flowing in two conductors are and
Magnetic field in wire,
Magnetic field due to current I1
Magnetic field due to current I2
When two parallel conductors are carrying currents in the same direction then the magnetic field will be added.
When the direction of one of the current is reversed then the magnitude of the magnetic field midway between them
Hence, the magnitude of magnetic field decreases in comparison to previous case.
Answer:
Answer:
15.67 seconds
Explanation:
Using first equation of Motion
Final Velocity= Initial Velocity + (Acceleration * Time)
v= u + at
v=3
u=50
a= - 4 (negative acceleration or deceleration)
3= 50 +( -4 * t)
-47/-4 = t
Time = 15.67 seconds
Answer:
A longitudinal wave is a wave where the movement of the medium is in the same direction as the wave. On the other hand, a transverse wave is a wave where the movement of the medium is at a right angle to the wave direction.
