Explanation:
The energy stored in an elastic objects as a result of deformation is called elastic potential energy. The energy stored in a spring is given by :
Where
k = spring constant
x = compression or stretching in an spring
While gravitational potential energy is given by :
PE = mgh
where
m = mass
g = acceleration due to gravity
h = height from ground
So, the factor affecting elastic potential energy but not gravitational potential energy is " spring constant ".
The electric current is measured in coulombs per second.<u> A flow of one coulomb per second is called one ampere</u>
Answer:
a) the Tunguska meteoric impact
Explanation:
The Tunguska Event, sometimes known as the Tungus Meteorite is thought to have resulted from an asteroid or comet entering the earth's atmosphere and exploding. The event released as much energy as fifteen one-megaton atomic bombs. As well as blasting an enormous amount of dust into the atmosphere, felling 60 million trees over an area of more than 2000 square kilometres. Shaidurov suggests that this explosion would have caused "considerable stirring of the high layers of atmosphere and change its structure." Such meteoric disruption was the trigger for the subsequent rise in global temperatures
According to Vladimir Shaidurov of the Russian Academy of Sciences, the apparent rise in average global temperature recorded by scientists over the last hundred years or so could be due to atmospheric changes that are not connected to human emissions of carbon dioxide from the burning of natural gas and oil.
Answer:
Q=∆U+W
Explanation:
work done+ change in internal energy = heat supplied to change the internal energy
(1st law of thermodynamics)
