Please answer the following essay question:

Physics
1 answer:
g100num [7]3 years ago
5 0

Explanation:

The atoms of elements such as hydrogen, sodium and potassium have only one electron in their outermost electron shell while atoms such as calcium, iron and chromium have several loosely held electrons. The bond would be almost entirely covalent. Ionic bonds form between atoms of very different electronegativities, e.g. sodium and chlorine, in which case the electron is largely removed from the sodium atom and transferred to the chlorine atom, resulting in sodium(+) chloride(-) ionic bonding

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-
Tanya [424]

Explanation:

Given that,

Terminal voltage = 3.200 V

Internal resistance r= 5.00\ \Omega

(a). We need to calculate the current

Using rule of loop

E-IR-Ir=0

I=\dfrac{E}{R+r}

Where, E = emf

R = resistance

r = internal resistance

Put the value into the formula

I=\dfrac{3.200}{1.00\times10^{3}+5.00}

I=3.184\times10^{-3}\ A

(b). We need to calculate the terminal voltage

Using formula of terminal voltage

V=E-Ir

Where, V = terminal voltage

I = current

r = internal resistance

Put the value into the formula

V=3.200-3.184\times10^{-3}\times5.00

V=3.18\ V

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

\dfrac{Terminal\ voltage}{emf}=\dfrac{3.18}{3.200 }

\dfrac{Terminal\ voltage}{emf}= \dfrac{159}{160}

Hence, This is the required solution.
