Answer:
Part a)
Work done is given as
W = -121.5 J
Part b)
Potential energy of the system is given as
Explanation:
As we know that work done by variable force is given as
here we know that
so we have
so we have
here we displace it from x = 2 to x = 5
so we will have
Part b)
As we know that change in Potential energy = work done
Answer:
Explanation:
The sun is made up of 6 parts. Namely:
- The core
- The radiation zone
- The convection zone
- The photosphere
- The chromosphere and
- The corona
The convection area is just above the radiation zone. As materials from the suns core are heated, they rise above the radiation zone towards the EDGE of the convection area then sinks back again into the radiative zone for more heat.
The radiative zone is 12.6 million Fahrenheit hot and is just above the core.
The core of the son is not solid but plasma whose motion is like gas. Its temperature stands at 48 million Fahrenheit
