Does salt or fresh water make a difference in floating of ships? plz answer ASAP will give brainliest to the best answer

The density of salt water is more than that of density of fresh water, so so salt and fresh water makes a difference in floating of ships.

Yes, salt or fresh water makes a difference in floating of ships.

Explanation:

Salt water is heavier than freshwater, the ships float higher in salt water than fresh water.

The density is higher, so less salt water will be displaced, and the ship will float higher.

f=ma newton

f=100x2.5=250n

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
