  liquid

Explanation:

If there are no s-waves, the interior must be liquid, where s-waves cannot travel.

Answer:

80C

Explanation:

As a substance gets hotter, or as a substance gets closer to the state of gas, the particles in the substance move faster, become more spread out and have more energy. This is why Gas has the most energy while solids have the least. Therefore, the hotter a substance is the more energy it has.

A glass of water at 80°C will have the most amount of energy

Explanation:

So, from this, we can conclude that glass with water at a higher temperature that is 80°C will have a  higher amount of energy than a glass of water at 20°C.

Answer:

I just finished a unit on Scientific Method in my science class! Anyway, it's defined in the screenshots below. Hope this helps!

Answer:

Your lungs deliver oxygen and remove carbon dioxide from your blood in a process called gas exchange. Gas exchange happens in the capillaries surrounding the alveoli, where the oxygen that is breathed in enters the circulatory system and carbon dioxide in the blood is released to the lungs and then breathed out.

Answer:

8.4 m/s

Explanation:

Initial velocity of the object is 0 as it was at rest.

We need to find the object’s average velocity during the 3 second to 5 second.

We can see from the graph that from 3 s to 5 s, the graph is a straight line. If we take the slope we can find the average velocity during the 3 second to 5 second.

Displacement between 3 s to 5 s is :

D = 24.8 m - 8 m = 16.8 m

Time = 5 s - 3 s = 2 s

Now,

Average velocity,

[tex]v=\dfrac{\Delta y}{\Delta x}\\\\y=\dfrac{16.8\ m}{2\ m}\\\\y=8.4\ m[/tex]

So, the object’s average velocity during the 3 second to 5 second is 8.4 m/s.

Answer:

The Moon’s appearance changes during its orbit around Earth. These changes are called phases.

Explanation:

The oil slick thick = 1.256 x 10⁻⁴ cm

Volume is a derivative quantity derived from the length of the principal

The unit of volume can be expressed in liters or milliliters or cubic meters

The conversion is

1 cc = 1 cm3

1 dm = 1 Liter

1 L = 1.06 quart

so for 1 quart = 0.943 L

[tex]\tt 0.943~L=0.943\times 10^{-3}m^3[/tex]

Volume of oil dumped = volume of swimming pool

[tex]\tt 0.943\times 10^{-3}~m^3=25\times 30\times h(h=thick)\\\\h=\dfrac{0.943\times 10^{-3}}{750~m^2}=1.257\times 10^{-6}~m=\boxed{\bold{1.256\times 10^{-4}~cm}}[/tex]

Answer:

C. I

Explanation:

The elements are categorized in groups and periods. The periods are horizontal and the groups are vertical. The elements in the same group (vertical) have very similar characteristics.

Answer:

osmosis. I

Explanation:

If an object/ cell is placed in a solution where the concentration is more or stronger than itself(hypertonic solution), it shrinks because water moves out of it, but if it is placed where the concentration of the surrounding solution is lesser than its concentration(hypotonic solution), it swells and can burst because water moves into it. So the mass of the egg will decrease because it is placed in an hypertonic solution (salt water) and the concentration of the salt water is stronger than its concentration

Explanation:

a pure substance is when something is made up of one type of thing, whether it be elements, where they are made up of one type of atom or a compound, where its atoms are chemically bonded and cannot be broken down by physical means

Answer:

C. Asthenosphere

Explanation:

Answer:

Breathe. Breathing is the number one thing every human does, and their bodies need it. Think about going in a pool in 6 feet. You realize that its kinda hard to breathe and it feels like something is holding your chest down really hard. Water pressure and air pressure can affect the breathing habits of a human and can also cause suffocation to the lungs.

Explanation:

1. sodium sodium is very reactive metal

2. when it exposed in air it automatically form Na2O.

3. when when it put in water it reacts visoroustly and start burning on water.

( due to this it is called active element)
