(a) How much gravitational potential energy (relative to the ground on which it is built) is stored in an Egyptian pyramid, give
1 answer:
Answer:
Or
2,668,320,000
Explanation:
Potential energy is given as the product of mass, acceleration due to gravity and height.
PE=mgh
Where m is the mass of pyramid, g is acceleration due to gravity and h is height at any point.
In reference to the earth, we substitute h for 34.0 m and g with 9.81 m/s2 then taking m as 8000000000 kg we get that
PE=mgh=8000000*9.81*34.0=2,668,320,000 J
In scientific notafion, this is expressed as

Answer:
Option B, Fix the piston in place so the volume of the pas remains constant
Explanation:
As we know
The effect on variable due to another variable can be studied by keeping the third variable constant.
Hence, in order the study the variation of temperature with pressure or vice versa, the volume needs to fixed at a certain value.
Hence, option B is correct
