Answer:do u have a text book so i can see
Explanation:
Answer:
In a closed-loop system, matter is used to generate energy, and the energy generated is used to produce matter, and the cycle goes on without end.
Explanation:
A closed-loop system is one in which materials or energy is recycled without end through a production cycle. This means that a raw material is used to produce a finished product, and the finished product at the end of its use cycle is converted back and used as a raw material to produce more of it again. Energy and matter can also be cycled in the same way in an energy and matter closed-loop system, converting matter to energy, and the energy is put back into the production of more of the matter.
1. b
2. c
3. A. Those are the answers
The options are missing and they are;
Select one:
A. By seeing it flying above the water
B. By listening for it in the air
C. By listening for it underwater
D. None of the above: it won’t be able to detect it in time.
Answer:
OPTION C is the correct answer:By listening for it underwater
Explanation:
Due to the fact that the ships and other boats have underwater microphones because on most cargo ships the engine is to loud so they use microphones underwater to detect torpedos. Thus, the vessel can detect the torpedo by listening under water
Answer:
1.8 x 10⁸ N / m²
Explanation:
Volume of 1000 kg of water = 1 m³
Volume of 1000 kg of ice = 1 / .917 = 1.09 m³
Change in volume = .09 m³
Volume strain = Change in volume / original volume = .09 / 1 = .09
Bulk modulus of elasticity of ice is 2 x 10⁹ N / m²
a ) Bulk modulus = change in pressure / volume strain
change in pressure = bulk modulus x volume strain.
Change in pressure = 2 x 10⁹ x .09 = 1.8 x 10⁸ N./ m².
When water inside the cell freezes it creates huge pressure on the cell wall
breaking it . Even walls of many internal structures of cell are broken leading it to die.
