Two blocks of masses 20 kg and 8.0 kg are connected togetherby
a light string and rest on a frictionless level surface. attached to
the 8-kg mass is a second light string, which a personuses to pull
both blocks horizontally. if the two blocks systemacdereates at 0.5
m/s2, what is the tension in the second stringattached to the 8-kg
mass?

14 N

Explanation:

The tension in the second string is puling both the masses of 20 kg and 8 kg with acceleration of 0.5 m s⁻²

So tension in the second string = total mass x acceleration

= 28 x .5 = 14 N . Ans..

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
