Gekata [30.6K]
Water molecules are COHESIVE due to HYDROGEN bonding. This property of water allows the individual molecules to stick to each other and allows for movement of water from roots to leaves. 

The correct answer is B. 
Water has certain qualities that allows it to be incorporated into the bodies of living organisms. Water forms hydrogen bonds because it is a polar molecule. The formation of these bonds leads to the cohesive nature of the substance making it suitable as a biological solvent.

A force is applied to a particle along its direction of motion. At what speed is the magnitude of force required to produce a gi
krek1111 [17]

Answer:

Explanation:

The detailed steps are as shown below

  • Recalling from F = ma
  • a = F/m
  • but magnitude of force F = √ [ 1 - v²/c²]

but acceleration twice as great as the force required to produce the same acceleration;

  • 2m = m / √[ 1 - v²/c²]
  • 2 = 1 / √ [ 1 - v²/c²]
  • square both sides ;

4 = 1 / [ 1 - v²/c²]

1/4 = 1 - v²/c²

v²/c² = 3/4

v/c = √ [3/4]

v = 0.87c

but speed of light c = 3 x 10^8m/s

v = speed of the particle =  0.87( 3 x 10^8m/s)

v = 2.61m/s
