In astronomy circumpolar constellations are those ones which never set from viewer's perspective like ursa minor, cassiopiea etc.
Because of the rotation of the Earth and its orbit around the Sun, we divide the stars and constellations into two groups. Some stars and constellations never rise nor set, and they are called circumpolar. All the rest are divided into seasonal stars and constellations. Which stars and constellations will be circumpolar and which seasonal depends on your latitude.
PE= mgh
m=mass =?
g=1.62
h= height = 30
PE= m(1.62)(30)
PE = 48.6m Joules
( if you left out the mass by mistake just multiply it by 48.6)
Answer:
Part a)
Part b)
Explanation:
As we know that conducting sphere is treated like spherical capacitor
so we can say
also we know that
so charge on two spheres will be in the ratio of their capacitance
Part a)
Part b)
Now potential difference between two sphere can be given as
Explanation:
The given data is as follows.
= 400 K, = 500 K,
= 25 kJ = 25000 J (as 1 kJ = 1000 J)
Now, we will calculate the change in entropy as follows.
Putting the given values into the above formula as follows.
=
= 250 J/K
Hence, we can conclude that change in entropy is 250 J/K.
Answer:
might collapse
