4.00 kg glass coffee cup is 30.0°C at room temperature. It is then plunged into hot dishwater at a temperature of 90.0°C, as shown in Figure below. If the temperature of the cup reaches that of the dishwater, how much heat does the cup absorb? C glass = 837 (J/kg.C)*

Answers

Answer:

Q = 200800 Joules.

Explanation:

Given the following data;

Mass = 4kg

Initial temperature = 30.0°C

Final temperature = 90.0°C

Specific heat capacity of glass = 837 J/kg°C

To find the quantity of heat absorbed;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt = T2 - T1

dt = 90 - 30

dt = 60°C

Substituting the values into the equation, we have;

[tex] Q = 4*837*60[/tex]

Q = 200800 Joules.

Therefore, the amount of heat absorbed is 200800 Joules.

A zebra drinks from a watering hole and is ambushed by a crocodile. What's more important and why: the zebra having a high maximum speed or a high acceleration?

Answers

Answer:

before this type of attack, high acceleration is the most important thing.

Explanation:

As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.

Consequently, before this type of attack, high acceleration is the most important thing.

D. Informatioŋ can be encoded in the wave speed.

Answers

I believe the answer is C or A but I’m not sure

One reason that electromagnetic waves are used in long-distance communication is, that they do not lose energy over long distances. So Option C   is correct

What are electromagnetic waves ?

Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields. They are propagated through space or through a material medium, and they have the ability to travel through a vacuum, which is the absence of matter. Electromagnetic waves have a wide range of frequencies, which determines the type of electromagnetic wave. The most familiar types of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

One of the property of the electromagnetic waves is that they do not lose energy over long distances.

Assuming complete dominance, the genotype for the dominant trait will always have at least one "capital" allele, so a creature with 2 arms would have genotype either AA (homzygous dominant) or Aa (heterozygous), while a creature with the recessive trait of having 4 arms will always be homzygous recessive with genotype aa.

Why is average global temperature the most important value when talking about climate change?

Answers

Answer:

The most important number's formal name is "equilibrium climate sensitivity," and it's meant to represent the new equilibrium in surface temperatures after a change in the amount of the Sun's energy trapped here on Earth rather than radiated back to space.

Explanation:

please give me brain list and follow

The average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.

What is temperature?

The temperature is the degree of hotness or coldness of the object.

The equilibrium climate sensitivity is the equilibrium in Earth's surface temperature. After the Sun's trapped energy is reduced, the climate changes accordingly.

Thus, the average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.

An 80 kg diver jumps from a 10 m high platform. What is the gravitational potential energy of the diver right before they jump (top of platform)

Answers

Answer:

0 Joules.

Explanation:

Given the following data;

Mass = 80kg

Height = 10m

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

We know that acceleration due to gravity is equal to 9.8m/s²

But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.

Gravitational potential energy= mgh

Gravitational potential energy = 80*9.8*0

Gravitational potential energy = 0 Joules.

This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.

This is True

Explanation:

Communities cooperate by simply co-existing and working together to benefit the community and offering their goods and services. Some programs in a community offer social work, like volunteering and charities, which help people in need in a community.

They can also be competitive because there are lots of the same goods and services offered throughout the city, so businesses have to compete for sales to attract consumers in the communities.

Explanation:

ay wants to buy a new fireplace insert that will burn gas instead of wood. She normally uses two cords of wood in the winter. Wood costs $250/cord. She is interested in knowing how much she will save if she burns gas in the fireplace insert. Gas costs $0.91 per therm. One therm is 100,000 BTU. The fireplace insert burns 33,000 BTU per hour. Kay figures she will burn the fireplace 5 hours per day for 120 days. How much will she save in one winter if she burns gas instead of wood

Answers

Answer:

Saved Money = $ 319.82

Explanation:

First, we will calculate the cost of wood:

[tex]Wood\ Cost = (No.\ of\ Cords)(Unit\ Cost)\\Wood\ Cost = (2 cords)(\$ 250/cord)\\Wood\ Cost = \$ 500\\[/tex]

Now, we calculate the time to burn gas:

[tex]Time\ to\ burn\ gas = (5\ hours/day)(120\ days)\\Time\ to\ burn\ gas = 600\ hr\\[/tex]

Now, we calculate the energy:

[tex]Energy\ Required = (600\ hr)(33000\ BTU/hr)(\frac{1\ therm}{100000\ BTU})\\\\Energy\ Required = 198\ therm\\[/tex]

Now, we will calculate the cost of gas:

[tex]Gas\ Cost = (Energy\ Required)(Unit\ Cost)\\Gas\ Cost = (198\ therm)(\$\ 0.91/therm)\\Gas\ Cost = \$\ 180.18\\[/tex]

Now, we will calculate the amount of money saved:

[tex]Saved\ Money = Wood\ Cost - Gas\ Cost\\Saved\ Money = \$\ 500 - \$\ 180.18\\[/tex]

Saved Money = $ 319.82

How does convection play a role in hurricanes

Answers

Answer:

Convection is what keeps the hurricane going in till the storm hits land.

Explanation:

Convection is the warm, moist current that rises above sea level and as it cools into water vapor it releases energy which a hurricane runs on. Once the hurricane hits land it continues to lose energy to keep it going because there's no convection from the sea currents rising above sea level to release energy.
