An incredible amount of electrical energy passes down the funnel of a large tornado every second. Measurements at a distance of 12.8 km from a large tornado showed an almost constant magnetic field of 2.35 × 10−8 T associated with the tornado. What was the average current going down the funnel? (µ0 = 4π × 10−7 T⋅m/A)

The average current going down the funnel is 1504 A.

Explanation:

Given that,

Magnetic field,

Measurements at a distance of 12.8 km from a large tornado, r = 12.8 km

We need to find the average current going down the funnel. We know that the magnetic field due to current carrying conductor is given by :

I is current

So, the average current going down the funnel is 1504 A. Hence, this is the required solution.

your answer is, orbit around the nucleus

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
