Answer:
The answer is below
Explanation:
Density is the amount of matter contained in a certain space. Objects that are dense are very heavy compared to their size while objects that are not dense are very light compared their size. Therefore most dense objects sink when placed in water while less dense objects floats in water.
Density is the ratio of mass to volume. It is given by:
Density = mass / volume
Crust has a density of 2.2 - 2.9 g/cm³ while core has a density of 9.9 - 12.2 g/cm³ for its outer and 12.8 - 13.1 g/cm³ for its inner.
Therefore if the same amount of a piece of crust is compared to a piece of core, the core would be more heavier since it has more density than the crust.

About 50 000 years ago, in an area located outside Flagstaff, Arizona, a giant
4.5 x 107-kg meteor fell and struck the earth, leaving a 180-m-deep hole now
known as Barringer crater. If the meteor was traveling at 20 000 m/s upon
impact, with what average force did the meteor hit the earth?
Answer:
F_A =5.625*10^1^6N
Explanation:
From the question we are told that
50,000 years ago,
A giant 4.5 107-kg meteor
180-m-deep hole
20,000 m/s

The can-chiller decreases the temperature of the liquid in the can by 15 °C.
The mass of liquid is 0.33 kg.
The specific heat capacity of the liquid is 4200 J / kg °C.
Calculate the energy transferred from the liquid as it cools.
Answer:
Energy transferred, Q = 20790 J
Explanation:
Given that,
The change in temperature of the liquid, [tex]\Delta T = 15^{\circ} C[/tex]
The mass of liquid, m = 0.33 kg
The specific heat capacity of the liquid is 4200 J/kg°C.
We need to find the energy transferred from the liquid as it cools. The energy transferred is given by :
[tex]Q=mc\Delta T\\\\Q=0.33\times 4200 \times 15\\\\Q=20790\ J[/tex]
So, 20790 J of energy is transferred from the liquid as it cools.

How does air outside the cup affect the knetic energy of the particles in the wall and the cold water
Answer:
Air outside the cup affect the kinetic energy of the particles in the wall and the cold water by transferring its heat to the cup and cold water.
Explanation:
The air outside the cup has a high temperature as compared to that of the cold water with in the cup.
As this hot and moist air it comes in contact of cup, it transfers its heat energy and become cool itself thereby leaving water droplet on the outer side of the cup.
Due to heat imparted to the cup, the atoms with in the cup and cold water starts vibrating and hence there kinetic energy increase.

What is the difference between a pure
substance, solution, and mixture?
A pure substance cannot physically be separated, and is made out of one atom (or molecule). Unlike a mixture, however, which are made out of two or more atoms or molecules. A solution in itself is the example of a mixture. (The composition of a pure substance being fixed, and a mixture's being varying depending on which.) And a solution branching off from a mixture into being either homogeneous mixtures or heterogeneous mixtures.
srry it kinda turned into a paragraph lol, feel free to add or take away anything :)

Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = T[/tex]
Hence ,option B is correct ✓
Over many years a limestone surface is exposed to slightly acidic rain. Which result is likely to occur in the limestone
Answer:
calcium carbonate is transformed into calcium sulfate
Explanation:
Limestone stones are formed by calcium carbonate (Ca Co3), when acid rain falls with a little H2SO2, a chemical reaction of the type
Ca Co3 + H2SO4 → CO2 + H2O + CaSo4
Calcium sulfate is much weaker than alatium carbonate, which is why the stone tends to break under its weigh

He asks you if you think positive incentives would work better than negative incentives.He is considering these options: - Raising or lowering prices - Applying discounts or fees - Offering exclusive memberships Bond's Gym should use to help solve the problem. If the owner of Bond's Gym raises his prices, the demand for membership will most likely . If the owner of Bond's Gym decides to raise his prices, he could make money per monthly membership.
Answer: Negative Incentives
Decrease
More
Explanation:
Took it on EDG 2021
Price can be defined as the amount of money that must be paid by a buyer (customer) to a seller (producer or owner), so as to acquire goods and services.
This ultimately implies that, it is an amount of money a customer that is buying goods and services are willing to pay to the seller (producer or owner) for the goods and services being offered.
In this scenario, we can deduce the following points:
If the prices of Bond's Gym services are raised, the demand for membership will most likely decrease.If the prices of Bond's Gym services are raised, the owner could make more money per monthly membership.Read more on price here: https://brainly.com/question/11898489
tony walks at an average speed of 70 m/min from his home to his school.If the distance between his home and the school is 2100 , how much time does it take for tony to walk to school
It takes 30 minutes for Tony to get to school.
2100 divided by 70 is 30, which would represent the amount of minutes.
Also he is walking very fast to be getting 70 in a minute.
Hope this helps and have a nice day.

Many people love roller coasters. Some people call them scream machines. They agree that riding a roller coaster is a thrilling experience. What you may not realize while you are going 60 miles an hour is that a roller coaster has no engine. You are not being propelled around the track by a motor or pulled by anything. A roller coaster moves on its own. How do you think that can happen?
HELP PLEASE!
Answer:
gravity & inertia
Explanation:
what goes up must come down & an object in motion will stay in motion until stopped
When two things are the same temperature:
А
Heat transfer between the two things stops
B
Their molecules stop moving
They have the same number of molecules
D
Their molecules move at the same average speed
Answer:
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.
