Gravity adds 9.8 m/s to the downward speed of a falling object every second. (On Earth.)

In 7 seconds, gravity adds (7 x 9.8 m/s) = <em>68.6 m/s</em> to the downward speed of a falling object.

(IF air resistance has no effect on the object.)

scoray [572]

Answer:

BA

0

\dfrac{NBA}{\Delta t}

Explanation:

B = Magnetic field

A = Area

\theta = Angle

t = Time taken

Before rotation the magnetic flux is given by

\phi_i=BAsin\theta\\\Rightarrow \phi_i=BAsin90\\\Rightarrow \phi_i=BA

Magnetic flux is BA

After rotation the magnetic flux is given by

\phi_i=BAsin\theta\\\Rightarrow \phi_i=BAsin0\\\Rightarrow \phi_i=0

The magnetic flux is 0

Magnitude of emf is given by

\epsilon=NA\dfrac{d\phi}{dt}\\\Rightarrow \epsilon=\dfrac{NBA}{\Delta t}

The magnitude of the average emf induced in the entire coil is \dfrac{NBA}{\Delta t}

For the answer to the question, ergonomics<span> is the science of fitting the job to the worker. When there is a mismatch between the physical requirements of the job and the physical capacity of the worker, work-related musculoskeletal disorders (MSDs) can result. Ergonomics is the practice of designing equipment and work tasks to conform to the capability of the worker, it provides a means for adjusting the work environment and work practices to prevent injuries before they occur.</span>
