Consider horizontal parallel plates with a fixed potential difference. The upper plate has a voltage difference of 30 V with the

lower plate, and they are separated by 3 cm. You move the two plates carefully to a separation of 4 cm. What is the strength of the electric field between the plates?

relation between potential difference and electric field is given as

E . d = \Delta V

so here we know that

d = 3 cm

\Delta V = 30 V

E \times 0.03 = 30

E = 1000 N/C

So now when plates are separated to 4 cm distance carefully

the potential difference between them will change but the electric field between them will remain constant

So at distance of 4 cm also the electric field will be E = 1000 N/C

an object is producing a sound that has a wavelength in air of 2.69m. If the speed of sound in air is 346m/s, what is the freque
Misha Larkins [42]

Answer:

129.74 Hz

Explanation:

Given:

Wave velocity ( v ) = 346 m / sec

wavelength ( λ ) = 2.69 m

We have to calculate Frequency ( f ) :

We know:

v = λ / t [ f = 1 / t ]

v = λ f

= > f = v / λ

Putting values here we get:

= > f = 346 / 2.69 Hz

= > f = 34600 / 269 Hz

= > f = 129.74 Hz

Hence, frequency of sound is 129.74 Hz.

A 6kg sled sliding on an icy surface experiences a 6-N frictional force exerted by the ice and the air resistive force of 0.6 N.
White raven [17]

The net force on the sled is 6.6 N pointing backwards, opposite to the direction it's sliding. That's why it's slowing down, and will eventually stop.

Describe What It Was Like Before The Big Bang. Vision It In Your Head.
Inessa05 [86]
That's a loaded question. Well to me, through what I have heard from others and theories, I imagine there was other universes before us. It wasn't just nothingness, there was another universe, perhaps in another dimension that either ended or is still around today. Alternate dimensions are a theory, so it was probably just a matter of when ours would be born. We could've been the result of reaching the singularity in a black hole or we could've been the continuation of a grand generation of universes. Either way, I think before us there was other things that filled the void of darkness that we imagine to be before us.
