The period is the reciprocal of the frequency.

                    T  =  1 / f .

'Hz' = 'Hertz' means 'per second' or ' /sec '.

       440 Hz  =  440/sec .

The period (reciprocal)  =  sec/440  =  0.0022727... repeating

                                                             =  2-3/11 milliseconds

What is drag? In what situations might it act on the force of gravity?
stepan [7]
Drag is passive, therefore it does not act on gravity. Drag is a mechanical resistance to motion. If the motion in question was induced by gravity drag it can impede that motion, but has no effect on the gravity. 

hope this helps!

How much time does it take a power drill accelerating at 64.3 rad/s2 to achieve
Diano4ka-milaya [45]

Answer;

= 0.244 seconds

Explanation;

500 rpm is equivalent to; 1500 × 2π radians per minute

   = 9424.8 rad/minute  

To get revolutions per second we divide by 60

  = 9424.8/60  

   = 157.08 radians per second.  

Then we divide by 64.3 rad/s^2 to get time;

    = 157.08/64.3

     = 0.244 seconds.
