Lightning occurs when there is a flow of electrons between the ground and thethunder cloud. The maximum rate of flow (current) i

s about 20,000 C/s (amps), andit lasts for about 100 microseconds. How much charge flows between the groundand the cloud in this time? How many electrons flow during this time?

Answer:

Explanation:

Given

maximum rate of flow is  \frac{\mathrm{d} i}{\mathrm{d} t}=20,000\ C/s

Time of flow t=100\ \mu s

Charge flows during this process

=\frac{\mathrm{d} i}{\mathrm{d} t}\times t

Q=20,000\times 100\times 10^{-6}

Q=2\ C

(b)Total no of electron(n)

If charge on one electron is q=1.6\times 10^{-19}

n=\frac{Q}{q}=\frac{2}{1.6\times 10^{-19}}=1.25\times 10^{19}

You would convert from grams to moles by using the ___________ of the substance.
Firdavs [7]

You would convert from grams to moles by using the molar mass of the substance. The answer is letter B. for example, the molar mass Carbon dioxide is 44.01 g/mol. It means that for 1 mole of carbon dioxide, it contains 44.01 grams of Carbon dioxide.

What is the strength of an electric field that will balance the weight of a 3.3 g plastic sphere that has been charged to -7.6 n
sp2606 [1]

As the plastic sphere is charged, therefore it experience an electric force when placed in an electric fields and also experiences gravitational force acts downward so the electric force must act upward.

Let  F_{E} is electric force and F_{G} is gravitational force.

If these forces are balanced, thereforeF_{E} = F_{G}

or                                                                      \left | q \right |E=mg\\\\\ E=\frac{mg}{\left | q \right |}

Given, q=-7.6 nC=-7.6\times10^{-9} C and  m=3.3 g= 3.3\times10^{-3} kg.

Substituting these values in above equation we get,

E=\frac{3.3\times10^{-3} kg\times9.8 m/s^{2} }{7.6\times10^{-9} C}\\\\E=4.2\times10^{6} N/C

Thus, the magnitude of electric field is 4.2\times10^{6} N/C.

As the charge is negative, the electric field at the location of the plastic sphere must be pointing downward.

In what direction does the induced current flow in the loop?
bogdanovich [222]

Answer:

Clockwise and counter clockwises, depands.

Explanation:

The direction of current in a loop of wire in a magnatic field depands on the direction in which the loop is moved and the applied magnatic field.

this is determined by what is called right hand rule.

I will give one scenario, let's say that the loop is moved upwards and the applied magnatic field is into the page (if you drew the loop in 2D on a piece of paper), in this case the direction would be clockwise.
