Answer:

Explanation:

Rocks tell us a great deal about the Earth's history. Igneous rocks tell of past volcanic episodes and can also be used to age-date certain periods in the past. Sedimentary rocks often record past depositional environments (e.g deep ocean, shallow shelf, fluvial) and usually contain the most fossils from past ages.

You have 50L of water, it froze. So find its new volume. Density of water is 1000kg/m^3 or 1kg/L, density of ice is 920kg/m^3 or
ad-work [718]

Answer:

D (density) = Mass / Volume

V (ice) = Mass / Density = 50000 g / .92 kg / L

V = 50 kg / .92 kg / L  

1 Liter of water weighs 1 kilogram = 50 L weighs 50000 g

V = 54.3 L     the mass does not change upon the change of phase (freezing)

Explain how the perfume atomizer works under Bernoulli's principle
ss7ja [257]

Answer:

In an atomizer, or perfume sprayer, you squeeze a rubber bulb to squirt air through a tube. Because of the Bernoulli principle, the air rushing through the tube has a lower pressure than the surrounding atmosphere. ... The perfume is pushed out of the tube and sprays into the air as a fine mist.

A car drives 215km east and then 45km north. What is the magnitude of the cars displacement? Round you answer to nearest whole n
kifflom [539]

Answer: 219.65\ \text{km}

Explanation:

Given

Car drives 215 km east and then 45 km North

Displacement is East direction is

\Rightarrow \vec{r_1}=215\hat{i}

Now, the displacement from that to 45 km North is given by

\Rightarrow \vec{r_{21}}=45\hat{j}

Net displacement is \vec{r_2}

\Rightarrow \vec{r_2}=\vec{r_1}+\vec{r_{21}}\\\Rightarrow \vec{r_2}=215\hat{i}+45\hat{j}

Magnitude of the displacement is

 \Rightarrow \left | r_{2} \right |=\sqrt{\left ( 215 \right )^2+\left ( 45 \right )^2}\\\Rightarrow  \left | r_{2} \right |=\sqrt{48250}\\\Rightarrow  \left | r_{2} \right |=219.65\ \text{km}
