Ocean breezes are due to which method of heat transfer?
A. conduction
B. convection
C. greenhouse gases
D. radiation
E. geothermal energy

Answers

Answer 1
It’s convection. Land warms and cools faster than water, so At night the heat moves from the land into the ocean. That kind of movement is called convection, where heat moves to cool places.
Answer 2

Ocean breezes are primarily due to convection, which is the transfer of heat through the movement of fluids or gases.  The correct option is B.

What is convection?

Convection is a method of heat transfer that occurs in fluids (liquids and gases) and involves the movement of material carrying thermal energy. In convection, heat is transferred by the movement of hot fluid from one place to another, which then causes the transfer of heat from the hot fluid to the cooler fluid or surface it comes into contact with.

Convection can occur in two ways:

Natural convection: It occurs due to the density differences caused by temperature variations within a fluid. When a fluid is heated, its density decreases, making it lighter and causing it to rise. As it rises, it cools, becomes denser and falls back down, creating a cycle that is known as a convection current.

Forced convection: In this type of convection, a fluid is forced to flow over a surface or through a channel, by an external agent like a fan or pump. The forced flow enhances the rate of heat transfer from the surface or through the channel, as compared to natural convection, where the fluid flow is driven only by buoyancy forces.

Convection is a very important process for heat transfer in many natural and industrial applications, including heating and cooling systems, meteorology, oceanography, and more.

Here in the Question,

Ocean breezes are primarily due to convection, which is the transfer of heat through the movement of fluids or gases. As the sun heats up the surface of the ocean, the air above it also heats up and rises. This creates a low pressure area that draws in cooler air from over the land, resulting in a breeze that blows from the ocean towards the shore. This is why sea breezes are generally felt during the day, when the land is warmer than the sea, and why they tend to die down at night, when the opposite occurs.

Therefore, The correct answer is B i.e convection.

If a motor is rated at 5.6KW, work done in 20minutes is equal to:​

Answers

Answer:

given Power= 5.6×1000=5600watt

t=20min=20×60=1200sec. work done=?

P=w/t

w=pt=5600×1200=672×10^4Joule

The amount of work done by the motor is equal to 6.72 Megajoules.

Given the following data:

Time = 20 minutesPower = 5.6 Kilowatt = 5600 Watts.

Conversion:

1 minute = 60 seconds20 minutes = [tex]20 \times 60 = 1200[/tex] seconds.

To determine the amount of work done by the motor:

Mathematically, the work done by an object with respect to power and time is given by the formula:

[tex]Work\;done = power \times time[/tex]

Substituting the given parameters into the formula, we have;

[tex]Work\;done = 5600 \times 1200[/tex]

Work done = 6,720,000 Joules

Note: 1,000,000 Joules = 1 Megajoules.

Work done = 6.72 Megajoules.

The electric field at a point 23 cm from a charged particle is 102424 N/C toward the particle. What is the charge on the particle? (Take k=9x109 Nm2/C2 )

Answers

Answer:

2.62×10⁻⁶ C

Explanation:

From the question,

Electric Field (E) = kq/r²....................... Equation 1

Where q = charge on the particle, r = distance of the electric field from  the charge,  k = coloumb's constant.

make q the subject of the equation

q = Er²/k.............................. Equation 2

Given: E = 102424 N/C, r = 23 cm = 0.23 m, k = 9×10⁹ Nm²/C².

Substitute these values into equation 2

q = (102424×0.23)/(9×10⁹)

q = 2.62×10⁻⁶ C

Hence the charge on the particle is 2.62×10⁻⁶ C

Answers

Answer:

Some electrons move from the neutral object to the positively charged object. Both objects become positively charged, but the object that started positively charged is less positively charged than it was initially.

Explanation:

This is because since protons do not move from the nucleus, but, electrons on the surface move, the electrons from the neutral object move to the positively charged object until there is no net movement of electrons between both objects. At this point, both objects carry the same charge and the positively charged object becomes less positively than it was initially.

Answers

Answer:

the correct answer is C,      E’= 4E

Explanation:

In this exercise you are asked to calculate the electric field at a given point

         E = [tex]k \frac{q}{r^2}[/tex]

indicates that the field is E for r = 2m

         E = [tex]\frac{ k q}{4}[/tex]                  (1)

the field is requested for a distance r = 1 m

         E ’= k \frac{q}{r'^2}

         E ’= k q / 1

 

from equation 1

         4E = k q

       

we substitute

        E’= 4E

The correct answer is - 200000 J

Explanation:

We use the formula of kinetic energy:

The formula to calculate kinetic energy is,

Here,

Ec =1/2 x  m x v^2

The mass of the roller coaster is,  m  =  1000  k g

The speed of the roller coaster is, v = 20.0 m/s

 Therefore,

Ec=1/2 x 1000kg x (20m/s)^2 = 200.000Joule

Se calienta para templar y endurecer, una llave española de acero de 200 gramos, elevando su temperatura hasta los 550°C y se introduce dentro de un recipiente de aluminio de 250 gramos de masa que contiene 220 gramos de agua. A 18°C. Determinar la temperatura final, cuando se alcanza el equilibrio térmico. Considere El CeHierro= 0.499cal/g°C; CeAluminio= 0.217cal/g°C; Ce agua=1cal/g°C

Answers

Answer:

La temperatura final es de aproximadamente 159,94°C

Explanation:

Los parámetros dados son;

La masa de la llave española de acero, m₁ = 200 gramos

La temperatura de la llave, T₁ = 550 ° C

La masa del recipiente de aluminio que contiene agua, m₂ = 250 gramos

La masa del agua en el recipiente de aluminio, m₃ = 220 gramos

La capacidad calorífica específica del hierro, [tex]C_{planchar}[/tex], c₁ = 0.499 ca/(g·°C)

La capacidad calorífica específica del aluminio, [tex]C_{Aluminio}[/tex], c₂ = 0.217 cal/(g·°C)

La capacidad calorífica específica del agua, [tex]C_{Agua}[/tex], c₃= 1 cal/(g·°C)

En equilibrio térmico, tenemos;

m₁·c₁·(T₁ - T) = m₂·c₂·(T -T₂) + m₃·c₃·(T - T₂)

Conectando los valores, da;

200 × 0.499 × (550 - T) = 250 × 0.217 × (T -18) + 220 × 1  × (T - 18)

Simplificando, usando una calculadora gráfica, obtenemos;

[tex]\dfrac{274450-499\cdot T}{5} = \dfrac{1097 \cdot T-19746}{4}[/tex]

De también encontramos 'T' al convertirlo en el tema de la ecuación anterior aún usando una calculadora gráfica;

T = 1196530/7481 °C ≈ 159.94°C

La temperatura final,T ≈ 159.94°C.

The final temperature, when thermal equilibrium is reached is 144°C.

Given the following data:

Mass of key = 200 gramsFinal temperature of key = 550°CMass of aluminum = 250 gramsMass of water = 220 gramsInitial temperature of water = 18°CSpecific heat capacity of key = 0.499 cal/g°CSpecific heat capacity of aluminum = 0.217 cal/g°CSpecific heat capacity of water = 1 cal/g°C

To determine the final temperature, when thermal equilibrium is reached:

Mathematically, heat capacity or quantity of heat is given by the formula;

[tex]Q = mc\theta[/tex]

Where:

Q represents the quantity of heat.m represents the mass of an object.c represents the specific heat capacity.∅ represents the change in temperature.

At an equilibrium state, the quantity of heat for the three substances is given by the equation:

[tex]M_kC_k(\theta_2 - \theta_1) = M_aC_a(\theta_2 - \theta_1) + M_wC_w(\theta_2 - \theta_1)\\\\200 \times 0.499 \times (500 - \theta_2) = 250 \times 0.217 \times (\theta_2 - 18) + 220 \times 1 \times (\theta_2 - 18)\\\\99.8(500 - \theta_2) = 54.25(\theta_2 - 18) + 220(\theta_2 - 18)\\\\49900 -99.8\theta_2 = 54.25\theta_2 - 976.5 + 220\theta_2 - 3960\\\\220\theta_2 + 99.8\theta_2 + 54.25\theta_2 = 49900 + 3960\\\\374.05\theta_2 = 53860\\\\\theta_2 = \frac{53860}{374.05}[/tex]
