A liquid has a density of 0.85 g/cm. If you pour some of the liquid into a glass of water, will the liquid float?
muminat

Answer:

Yes, it will float.

Explanation:

It is given that,

A liquid has a density of 0.85 g/cm³.

We know that, the density of water is 1 g/cm³.

The density of the liquid is less than that of water. If the density of the liquid is less than that of water, it will float in it. Hence, if you pour some of the liquid into a glass of water, it will float.

KATRIN_1 [288]

Students and scientists construct scale models of natural phenomena to better observe patterns and relationships.

What is natural phenomena?

Things that happen naturally—phenomena—occur or show up without human intervention. Gravity, tides, moons, planets, volcanic lightning, starling swarms, ant armies, sandstorms, biological processes and oscillation, among countless more events, are examples of natural phenomena.

Scientists and students  use models to help them visualize their current understanding of a system in the condition that it is in right now.

Mrrafil [7]

Answer:

v_1  = 3.5 \ m/s

Explanation:

Given that :

mass of the SUV is  = 2140 kg

moment of inertia about G , i.e I_G = 875 kg.m²

We know from the conservation of angular momentum that:

H_1= H_2

mv_1 *0.765 = [I+m(0.765^2+0.895^2)] \omega_2

2140v_1*0.765 = [875+2140(0.765^2+0.895^2)] \omega_2

1637.1 v_1 = 3841.575 \omega_2

\omega_2 = \frac{1637.1 v_1}{3841.575}

\omega _2 = 0.4626 \ v_1

From the conservation of energy as well;we have :

T_2 +V_{2  \to 3} = T_3 \\ \\ \\  \frac{1}{2} I_A \omega_2^2 - mgh =0

[\frac{1}{2} [875+2140(0.765^2+0.895^2)](0.4262 \ v_1)^2 -2140(9.81)[\sqrt{0.76^2+0.895^2} -0.765]] =0

706.93 \ v_1^2 - 8657.49 =0

706.93 \ v_1^2  = 8657.49

v_1^2  =  \frac{8657.49}{706.93 }

v_1 ^2 =  12.25

v_1  = \sqrt{ 12.25

v_1  = 3.5 \ m/s
