C. The flat and long shoes are used to walk an snow ? why give reason

here's your answer...

it is because ordinary shoes have thin or narrow base as compared to snow shoes so they apply more pressure on the snow as compared to the snow shoes

that is why they help us to walk on snow easily

hope it helps if yes please let me BRAINLIEST!

Tysm!

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

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
