<h3>Solution for the above question : -</h3>
Ohm's law states that :
the terms used are :
let's solve for electric current :

Note: I'm not sure what do you mean by "weight 0.05 kg/L". I assume it means the mass per unit of length, so it should be "0.05 kg/m".
Solution:
The fundamental frequency in a standing wave is given by

where L is the length of the string, T the tension and m its mass. If we plug the data of the problem into the equation, we find

The wavelength of the standing wave is instead twice the length of the string:

So the speed of the wave is

And the time the pulse takes to reach the shop is the distance covered divided by the speed:
The genotype for all offspring will be Pp making the flower color white.
The answer is 5. To find the advantage you just divide 20 by 4.
