No. There are stronger and more powerful nuclear weapons, but nothing is stronger than a nuclear weapon.
Conduction requires objects to have direct contact; convection does not.
Answer:
Explanation:
chemical energy of 1 kg coal is 3 million joules .
If this energy is used to lift one kg of coal , let height attained be h
chemical energy = gravitational energy of 1 kg of coal
3 x 10⁶ = m g h = 1 x 10 x h
h = 3 x 10⁵ m
= 300 x 10³ m
= 300 km .
i kg coal can be lifted by height of 300 km .
Answer:
14 ft 7 inches
step-by-step explanation:
since each model inch corresponds to 25 real inches, 7 model inches will correspond to
7×25" = 175"
at 12" per foot, that is 14 feet, 7 inches.
Explanation:
<span> We look for

happening in real-time because they happen over large time scales, or
large spatial scales. But we can observe the effects of these
phenomenon and make predictions about what other effects we should see. </span>
