The climate of a location is affected by the presence of A Oceans.

There are some climates factors that might affect the temperature of a location, these factors are latitude and attitude as well as distance from waterly places such as oceans (ocean currents).
Places along the coasts would be prevented from extremes hot or cold climates.

The answer is; oceans. I think this is the answer as the others do not make sense.

Hope this helped! :)

The correct answer of the given question above would be option B. The statement that is not correct is that, a steady magnetic field produces a steady current. The rest of the statements are all correct. An unchanging/static magnetic field (relative to a wire/circuit) induces zero current.

A motorcycle at a stoplight takes 4.22 seconds to accelerate 28.0 m/s after the light turns green. what is the acceleration?

stira [4]

Acceleration=velocity/time
acceleration=28/4.22
therefore, acceleration=6.64

A constant torque of 3 Nm is applied to an unloaded motor at rest at time t = 0. The motor reaches a speed of 1,393 rpm in 4 s.

Answer:

The moment of inertia of the motor is 0.0823 Newton-meter-square seconds.

Explanation:

From Newton's Laws of Motion and Principle of Motion of D'Alembert, the net torque of a system ( $\tau$ ), measured in Newton-meters, is:

$\tau = I\cdot \alpha$ (1)

Where:

$I$ - Moment of inertia, measured in Newton-meter-square seconds.

$\alpha$ - Angular acceleration, measured in radians per square second.

If motor have an uniform acceleration, then we can calculate acceleration by this formula:

$\alpha = \frac{\omega - \omega_{o}}{t}$ (2)

Where:

$\omega_{o}$ - Initial angular speed, measured in radians per second.

$\omega$ - Final angular speed, measured in radians per second.

$t$ - Time, measured in seconds.

If we know that $\tau = 3\,N\cdot m$ , $\omega_{o} = 0\,\frac{rad}{s }$ , $\omega = 145.875\,\frac{rad}{s}$ and $t = 4\,s$ , then the moment of inertia of the motor is:
