51. suppose you measure the terminal voltage of a 3.200-v lithium cell having an internal resistance of 5.00ω by placing a 1.00-kω voltmeter across its terminals. (a) what current flows? (b) find the terminal voltage. (c) to see how close the measured terminal voltage is to the emf, calculate their ratio.

Explanation:

Given that,

Terminal voltage = 3.200 V

Internal resistance

(a). We need to calculate the current

Using rule of loop

Where, E = emf

R = resistance

r = internal resistance

Put the value into the formula

(b). We need to calculate the terminal voltage

Using formula of terminal voltage

Where, V = terminal voltage

I = current

r = internal resistance

Put the value into the formula

(c). We need to calculate the ratio of the terminal voltage of voltmeter equal to emf

Hence, This is the required solution.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
