Answer:
I think the answer might be A
Explanation:
because if its called Pillars creation then something important might be being born maybe
Answer:
Explanation:
we know that the time rate of change of velocity is called acceleration mathmetically;
a=Δv/Δt
Δv=a*Δt
a=10 m/s²
t=10 sec
Δv=10*10=100 m/s
Answer:
-730KJ
Explanation:
According to the first law of thermodynamics;
Let the total energy of the system be ∆E
Let heat be q and let work the w
Since the energy decreases ∆E is negative
Since work is done on the system w= positive
So;
- 250 = 480 + q
q = -250 - 480
q=-730KJ
Answer:
Option B) The fuel for nuclear fusion comes from sea water
Explanation:
Nuclear fusion can not be carried out by using any type of water as water is composed of stable water molecules (
which is quite difficult to be decayed by any simple method.
Moreover, fusion reactions demands the combination of nuclei of lighter elements for which it makes use of the heavy isotopes of Hydrogen that are Deuterium and Tritium as fuel to carry out the nuclear fusion.
