It makes calculations with very large and small numbers easier.
Scientific notation is a system used in order to It makes calculations with very large and small numbers easier. It is useful as it allows very large number that would take a lot of space to write otherwise, and it allows them to be calculated easier. 
for example is a incredible large number, but written in this form is immediately understandable and useful for calculation.
Explanation:
1) The bob of pendulum should be displaced with a small angle. 2) The amplitude of the oscillation of a simple pendulum should be small. 3) Fans should be switched off to reduce the air resistance. 4)The simple pendulum should be oscillate in a vertical plane only.Feb 23, 2019
Answi am sorry but i do not know the answer
Explanation:
According to Charles law, if pressure remains constant, volume varies directly with temperature. so we can infer that :
So, we can use this formula to find out the final temperature of the gas ~
Note : Take temperature in Kelvin ( 100°C = 373 K )
Now, convert it to Celsius ~
i.e 746 - 273 = 473° C
So, the final temperature of the gas will be equal to 473° C
(1,500 meters) x (1 sec/330 meters) =
(1,500 / 330) (meters-sec/meters) =
4.55 seconds
