Entropy tends to increase. Apex
Answer:
Explanation:
Given,
initial angular speed, ω = 3,700 rev/min
=
final angular speed = 0 rad/s
Number of time it rotates= 46 times
angular displacement, θ = 2π x 46 = 92 π
Angular acceleration
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.
They are formed by cooling 0f molten magna on Earth's surface.
The bike is maintaining "constant velocity". He's moving at 15 m/s when we see him for the first time, 15 m/s later that day, and 15 m/s next week.
The car starts from zero, and goes 4.0 m/s FASTER each second. After one second, it's going 4.0 m/s. After 2 seconds, it's going 8 m/s. And after 3 seconds, it's going 12 m/s.
This is the point at which the question wants us to compare them ... 3 seconds. The bike is moving at 15 m/s and the car has sped up to 12 m/s. <em>The bike is moving faster than the car.</em>
If we hung around and kept watching for another second, the car would then be moving at 16 m/s, and would be moving faster than the bike. But we lost interest after answering the question, and we left at 3 seconds.
