Unlike freshwater fish, saltwater fish
Olin [163]


The best answer is A

Saltwater fish are hypotonic to their surroundings. This means their blood has a higher water concentration than the surrounding sea water.

Due to the fact that there is more salt and less water outside their bodies, there is a tendency to take in salt and lose water.

To counter this, salt water fish drink a lot of the sea water and urinate very little. Special cells in the gills actively eliminate salt at the cost of extra energy and these fishes do not absorb any salt from the water they drink.

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
