In a stronger gravitational field a given mass will have a larger weight.
Answer;
- Nuclear fusion
Explanation;
-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.
-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.
-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.

Answer:
1.45m
Explanation:
Detailed explanation and calculation is shown in the image below
Answer: a) 222k/m
b) 42.5W
c) if cold: 26.7C
If hot: 73.3C
Explanation:
If TH and TC are at the ends of the rod in the figure, then;
(A) 100 K / 45 cm = 2.22 K/cm or 222 K/m
(B) thermal conductivity constant for copper is 390 W/(m K).
Then the heat flow rate = Q/t
Q/t = [390 W/(m K)] (100 K) [ pi (0.0125 m)^2 ] / (0.45 m)
= 42.5 watts
(C) 12/45 = 4/15 = 0.2667
If the left end is the cold end, the answer will be 26.7 C
If the left end is the hot end, the answer will be 73.3 C
