Answer:
Rocks get older as we go away from the Mid Atlantic Ridge towards the continents
Explanation:
As the plates move away from each other, new ocean lithosphere is created at the ridge. This also widens the ocean basin and leads to sea floor spreading.
The rock of the ocean floor are symmetrically aligned and they get become older as they move away from the crest of the ridge.
Thus, rocks get older as we go away from the Mid Atlantic Ridge towards the continents
A truck at the top of the hill has higher gravitational potential energy then when it is at the bottom of the hill. Why does it roll downhill?
1. To increase its kinetic energy
2. To lower its potential energy
3. To increase the entropy of the universe
4. To decrease the entropy of the universe
Answer:
An object that goes up a hill will be going at a slower speed at the top than at the bottom of the hill. This is because moving up or down a hill changes one kind of energy into another. Objects at the bottom of the hill have more kinetic energy, which means they are moving faster.

Anatom of an element has no electron,will that atom have any mass or not? Can antom exist
without electron? if so give an example.
Answer:
Generally, all atoms of elements contain three sub-atomic particles- Protons(Positively-charged), Neutrons(Neutral) and Electrons(Negatively-charged).
The Magnitude of the Positive Charge possessed by the Protons and the Magnitude of the Negative Charge possessed by the Electrons cancel each other, which make the atom electrically neutral.
Hence,
Without any electrons, the magnitude of the positive and negative charges wouldn't balance, and the atom would be unstable and disintegrate almost immediately. Hence, all stable atoms should have electrons revolving around them, where the number of protons and electrons are the same, under normal conditions.
To Conclude,
Every atom of an element will have electrons arranged in different shells, or matter couldn't exist without electrons.
Q7: Your car has a mass of 1000 kg. If your car produces a force of 3000 N, how fast will it accelerate?
Answer:
3 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]acceleration = \frac{force}{mass} \\[/tex]
We have

What makes a gas a gas?
Answer:
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).

Someone said that light bent around a corner to reach an object. Is this possible?
Answer: Yes, light can bend around corners. ... The ability of light to bend around corners is also known as "diffraction". There are two mechanisms that cause light to bend around corners. Light waves indeed bend around corners because of diffraction, as shown in this illustration.

Two elements are in the same group of the Periodic Table.
Which property will be the same for both elements?
A the charge on their ions
B their electronic structure
C their melting point
D their reactivity with water or acids
Answer:
A. the charge on their ions
Explanation:
Elements are grouped into the same group in the periodic table if they have the same valence electrons. However, the number of valence electrons an element has, determines the number of charges it can possess.
According to this question, two elements in the same group of the periodic table will have the same charge on their ions because they both have the same number of valence electrons.

4. Ionic compounds conduct electricity when they are in the __ state
Answer:
Salts do not conduct electricity at the solid state since the ions are in a fixed position in the lattice. However, at the molten state or in solution, the ions are free and they can move within the liquid phase to serve as electrons shuttles and therefore, they become conductive.
Explanation:
A gas occupies 56 L at 73°C. What volume will the gas occupy if the temp. cools to 0°C?
Answer:
44.2 L
Explanation:
Use Charles Law:
[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]
We have all the values except for V₂; this is what we're solving for. Input the values:
[tex]\frac{56 L}{346K} =\frac{V2}{273K}[/tex] - make sure that your temperature is in Kelvin
From here, we need to get V₂ by itself. To do this, multiply by 273 on both sides:
[tex]\frac{56*273}{346} = V2[/tex]
Therefore, V₂ = 44.2 L
It's also helpful to know that temperature and volume are linearly related. So, when temperature drops, so will volume and vice versa.
How many milliliters of a 3.28 M copper (II) nitrate Cu(NO3)2
solution are needed to provide a total of 146.59 g of Cu(NO3)2?
Use 187.56 g/mol as the molar mass of solute. Solve your answer
to two decimal places.
Answer:
237.80mL
Explanation:
Molarity of a solution can be calculated using the formula;
Molarity = number of moles (n) ÷ volume (V)
However, we first need to calculate the number of moles of Cu(NO3)2 by using the formula:
moles = mass/molar mass
Molar mass of Cu(NO3)2 = 187.56 g/mol
moles = 146.59 ÷ 187.56
moles = 0.782moles
Molarity = n/V
3.28 = 0.78/V
V = 0.78/3.28
V = 0.2378L
In milliliters (mL), 0.24 litres = 0.24 × 1000
= 237.80mL

A chemical reaction is carried out in a closed container. the energy absorbed by the chemical reaction is 100 kj. What is the energy liberated from the air or the walls of the container?
A. 100 kJ
B. 50 kJ
C. 25 kJ
D. 75kJ
Answer:
Option A
Explanation:
The total heat absorbed during the chemical reaction is the total heat released by the surrounding.
Net change of heat is equal to zero
Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj
Thus, option A is correct
Jennifer has a jar full of stones. For one year, Jennifer shakes the jar several times each day. The illustration below shows the changes that occurred after one year. What process does this illustration show?
Jennifer has a jar full of stones. For one year, Jennifer shakes the jar several times each day. The illustration below shows the changes that occurred after one year, and this shows that because of the fragmentation, this happens.
Initially, before a year, there were many rocks, but as she continuously shrank the box, that led to the fragmentation. Due to vibration for a long time, the larger rocks break into the smaller particles as a result of the amount of rocks converted into the small particles and sands. These smaller stone fragments may then accumulate at the bottom of the jar as a result of this there is a decrease in the overall number of stones in the jar.

[ ]True
Answer:
I am not sure this one is False.
Explanation:
Answer:
False
Explanation:
This is false because the outer part of earth is cooler than the inner. For example, the inner is filled with lava, and all kinds of stuff, so this is technically saying that the outer is much cooler, It has dirt, and dirt can be cool.
why should we put a glass on candles for experiments and why should we put candles on sand trays ?
Answer:
1, you should use candles for experiments because, You created an area of low pressure! When the experiment is run you can see tiny bubbles escaping under the glass which shows that the increased air pressure from the heated air as the candle burns. Once the candle runs out of oxygen, the candle burns out and the remaining air inside cools down.
2. you should put candles on sand trays, Pour layers of sand into a glass vase, alternating colors with each layer. For a more interesting look, try uneven layers in various heights. Keep layering sand until you're a few inches from the top of the vase. Place your votive candle in the center of the sand.

The graph shows a heating curve for water.
Which point on the graph indicates that all of the liquid water has been converted to water vapor?
1
2
3
4
Answer:
4
Explanation:
water starts to boil into water vapor at 100'C. at this point, temperature becomes costant at 100'C as heat energy is used up by the particles to overcome the intermolecular forces between the molecules.
once the forces holding the particles together have been overcome, the temperature will start to rise again showing that all the liquid water has been converted into water vapor
