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.

Answer:
distance covered is 4.5km or 1.25m
Explanation:
GIVEN DATA:
SPEED=v=3km/h
TIME=t=1.5h
TO FIND:
DISTANCE COVERED=d=?
SOLUTION:
As we know that
speed=distance covered /time taken
here we have to find distance
speed×time taken=distance covered
3km/h×1.5h=distance covered
4.5km=distance covered or in international system of unit the answer is 1.25m
