Answer:

B. Longer than t s,

Explanation:

Gravitational accln on earth is 9.8 m/s^2,

and one you provided as on moon is 1.6 m/s^2

that mean on moon gr. accl. is lesser!

now the time taken on earth will be lesser cuz from the same height if you drop the object from rest!

since accln on earth is higher,the object will attain higher velocity as compare to that of on moon!

✌️:)

Choose the items that help to fully describe voltage.
Zina [86]

Answer:

the easy way to describe this is to use a light as an example.

Explanation:

Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.

Your friend is trying to construct a clock for a craft show and asks you for some advice. She has decided to construct the clock
Anastasy [175]

Answer:

The period of the pendulum is  T  =  1.68 \  sec

Explanation:

The diagram illustrating this setup is shown on the first uploaded image

From the question we are told that

     The length of the rod is L =  80 \ cm

       The diameter of the ring is d = 10 \ cm

       The distance of the hole from the one end  D =  15cm

From the diagram we see that point A is the center of the brass ring

 So the length from the axis of  rotation is mathematically evaluated as

          AP = 80 + 10 -5 -15  

          AP =  70 \ cm =  \frac{70}{100}  =  0.7 \ m

Now the period of the pendulum is mathematically represented as

             T  = 2 \pi  \sqrt{\frac{AP}{g} }

             T  =  2 \pi \sqrt{\frac{0.7}{9.8 } }

             T  =  1.68 \  sec
