Answer:
6.97 E 16
Explanation:
Frequency is a function of velocity of light to it's wavelength.
Mathematically written as
F = Velocity / wavelength
Velocity of light = 3 x 10^8
Wavelength =430 nm =430 x 10^-9 m
converting wavelength from nanaometer to meter we divide by 10^9
Frequency = (3 x 10^8)/(430 x10^-9) =6.97 E 16

Answer:

Explanation:
- We have to make a hollow sphere of inner radius
and outer radius
.
Then the mass of the material required to make such a sphere would be calculated as:
Total volume of the spherical shell:

And the volume of the hollow space in the sphere:

Therefore the net volume of material required to make the sphere:


- Now let the density of the of the material be
.
<u>Then the mass of the material used is:</u>


The charge transported as a result of charging is 43200C .
we can note the following data from the statement :
Current (i) = 3A
Time interval (t) = 4 hrs = 14400secs
As we know ,
Current is defined as the rate of flow of the charges between two points when a potential difference is applied between them.
Mathematically , it can be written as
Current(i) = charge (q)/ time(t)
Q = i × t
= 3 × 14400
= 43200 C
By dividing the value of the current passed through the circuit by the time for which the charge is passed gives out the value of the charge passed .
