Any Acellus folk figure out the answer to this one??? I CANNOT for the life of me.
Olin [163]

Answer:

-0.10472\frac{rad}{s}

Explanation:

Remember that any <u><em>clockwise</em></u> rotation is considered negative, and any <u><em>counterclockwise</em></u> rotation is considered positive.

The formula for period is:

T = \dfrac{2\pi}{\omega}

Solve for \omega\\ and you get:

\omega=\dfrac{2\pi}{T}

The period is 60 seconds so make that division and you're left with -0.10472\frac{rad}{s} or -0.10\frac{rad}{s} if significant figures apply (negative because the rotation is clockwise).

alekssr [168]

Complete Question

A step-up transformer is connected to a generator that is delivering 197 v and 113 A. The ratio of the turns on the secondary to the turns on the primary is 600 to 5. What is the voltage across the secondary

Answer:

The voltage is V_s  =  23640  \  V

Explanation:

From the question we are told that

   The  voltage is  V_p  = 197  \ V

    The current is  I  =  113  \  A

   The  number of turn on the secondary is  N_s =  600 \ turns

    The  number of turn on the primary is  N_p =  5 \  turns

Generally from the Transformer Turns ratio equation

    \frac{N_s}{N_p} = \frac{V_s}{V_p}

=>  \frac{ 600}{ 5} = \frac{V_s}{197 }

=>  V_s  =  23640  \  V

At what point in a projectile’s trajectory does it experience a minimum velocity?
ad-work [718]
Minimum velocity occurs at the top of the trajectory, where
the projectile stops rising and starts falling.  For a split second,
it has no vertical speed at all, and its velocity is only the horizontal
speed (which doesn't change).
