Answer:

When the tin is heated, the air within and water molecules expand. As the volume expands, so does the tin container up to a limit.

**Explanation:**

weight of water displaced=weight of sphere,

Since, plastic sphere floats in water with 50.0% of its volume submerged

so, water=2 sphere,

so sphere's density = 1/2 of water's density

Now, weight of glycerin displaced=weight of sphere,

Also given This same sphere floats in glycerin with 40.0% of its volume submerged.

so glycerin =2.5 sphere,

so sphere's density = .4 of glycerin's = 1/2 of water's.

So glycerin = 1.25 water

B is or answer because they are both the same heat

B, a mixture in which its components retain their identity.

Their **velocity **(in m/s) just after impact if they cling together is **-0.9 m/s.**

**Final speed of the two players**</h3>

Apply the principle of conservation of **linear momentum;**

Pi = Pf

where;

- Pi is initial momentum of the players
- Pf is final momentum of the players

(92.5)(5.5) + (116)(-6) = v(92.5 + 116)

508.75 - 696 = v(208.5)

-187.25 = 208.5v

v = -187.25/208.5

v = -0.9 m/s

Thus, their **velocity **(in m/s) just after impact if they cling together is **-0.9 m/s.**
