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.
False. you have to find out how many seconds are in the 25 min. 60 x 25 is 1500sec. Then multiply 1500 by .75 to get 1,125m. There are 0.001 kilometers in a meter. Move the decimal point three spaces to convert m to km. 1,125m becomes 1.125km

GiveN:
- Initial velocity = 9.8 m/s²
- Accleration due to gravity = -9.8 m/s²
- Time taken = 1 s
To FinD:
- Final velocity of the ball?
Step-by-step Explanation:
Using the first Equation of motion,
⇒ v = u + gt
⇒ v = 9.8 + -9.8(1)
⇒ v = 0 m/s
The final velocity is hence <u>0</u><u> </u><u>m</u><u>/</u><u>s</u><u>.</u>

Note:</h3>
- While solving questions of under gravity motions using equations of motion, remember the sign convection to avoid mistakes.
- You can consider positive above the ground and negative for towards it.
