Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maxi

mum rate of charge flow in a lightning bolt is about 20,000C/s; this lasts for 100μs or less. How much charge flows between the ground and the cloud in this time?

Answer:

2C  charge will flow from ground and cloud

Explanation:

We have given rate rate of flow of charge \frac{dq}{dt}=20000C/sec

Time is given as t=100\mu sec=100\times 10^{-6}=10^{-4}sec

WE have to find the how much charge flows between the ground and cloud in this time

So the charge flow is given by \frac{dq}{dt}\times t=20000C/sec\times 10^{-4}=2C

So 2C  charge will flow from ground and cloud

uysha [10]

100000 Pascal

Explanation:

pressure= force/area

Max pressure= force/min area

so f=5

min area= 5×10^-5

5÷5*10^-5 = 100000pascal

If there is a huge boulder on your lawn and you want to determine its density, but it is
Olin [163]

There are different options here but all of them work by approximating and assuming.

i) that the boulder is above ground.

ii) that the bottom surface of the boulder is known.

iii) the shape of the boulder is taken into account.

The most accurate way is measuring it by displacement method but the boulder is immovable hence the volume can be calculated by measuring the boulder or a waterproof box to be built around the boulder and calculate the volume occupied by boulder.

All the above methods are estimating methods.

*Another way to find the density is through specific gravity.

S.G = <u>Density</u><u> </u><u>of</u><u> </u><u>object</u>

Density of water

If the material that makes the boulder is known that is if it's stone or a mineral then the specific gravity can be found.

If the boulder is purely rock then S.G lies between 3 - 3.5 and the density of water is known thus the density of the boulder can be found without moving the boulder.

This is what I think after correction and allthe best!
