Answer:

C. Oil is made of non-polar molecules, and water is made of polar molecules.

Explanation:

Non-polar molecules = hydrophobic (water-fearing, doesn’t readily dissolve in water)

Ions & Polar molecules: hydrophilic (water-loving, does readily dissolve in water)

What happens when exhale

polet [3.4K]

When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

Please i need your help w/h/w you make the following measurements if an object:42kg, and 22m

Rufina [12.5K]

Answer:

$1.9 kg/m^3$

Explanation:

The density of an object is given by

$d=\frac{m}{V}$

where

m is the mass of the object

V is its volume

In this problem,

m = 42 kg

V = 22 m^3

Substituting into the equation, we find the object's density:

$d=\frac{42 kg}{22 m^3}=1.9 kg/m^3$

Answer:

Explanation:

Let the required velocity of rocket be v .

We shall use the formula of time dilation to find the velocity of rocket .

t = $\frac{t'}{\sqrt{1-\frac{v^2}{c^2} } }$

t = 430

t' = 38

$430=\frac{38}{\sqrt{1-\frac{v^2}{c^2} } }$

$\sqrt{1-\frac{v^2}{c^2} } }=\frac{38}{430}$

$1-\frac{v^2}{c^2}$ = .0078

$\frac{v^2}{c^2}$ =.9922

$\frac{v}{c}$ = .996

v = .996 x 3 x 10⁸ m /s

= 2.988 x 10⁸ m /s

B )

Kinetic energy of rocket

= 1/2 m v²

= .5 x 20000 x (2.988 x 10⁸ )²

= 8.9 x 10²⁰ J .

C )

This energy is 8.9 times the energy requirement of United states in the year 2005 .
