That statement is <em>false</em>.
"Condense" is what a gas does when it turns into liquid, and that's something that happens when the gas is cooled, not heated.
Answer:
80.33F
Explanation:
(300-273.15)*9/5+32=80.33
Answer:
From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star.
Answer: (a) 5Joules
(b) 10m/s
(c) 1.0kgm/s
(d) 33.3N
Explanation:
(a) P E = mass * gravity * height
= 0.1*10*5 = 5Joules
(b) All PE is converted to KE
Therefore;
KE = 1/2 * mass * velocity^2
5 = 1/2 * 0.1 * v^2
V = sqrt(100)
v = 10m/s
(c) change in momentum = mass * velocity
= 0.1 * 10
= 1.0kgm/s
(d) impulse = change in momentum
Change in momentum = force * time
1.0 = force * 0.03
Force = 1.0/0.03
Force = 33.3N
Therefore, the force acting on the egg is 33.3N
Coal is burned to get energy. By burning coal, green houses gases like carbon dioxide, nitrogen oxides and suphur oxides are produced.
Rest of the energy sources given in the option are clean energies.
Answer is A.
