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.

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.

Speed : The distance travelled by a body per unit time is know as speed.

Hope it will help.

Answer:

Momento = 170.8 Kgm/s

Explanation:

Dados los siguientes datos;

Masa = 3,05 kg

Velocidad = 56 m/s

Para encontrar el impulso;

El momento se puede definir como la multiplicación (producto) de la masa que posee un objeto y su velocidad. El momento se considera una cantidad vectorial porque tiene magnitud y dirección.

Matemáticamente, el momento viene dado por la fórmula;

[tex] Momento = masa * velocidad [/tex]

Sustituyendo en la fórmula, tenemos;

[tex] Momento = 3.05 * 56 [/tex]

Momento = 170.8 Kgm/s

Answer:

Part A

The distance travel by the rock is approximately 132.496 m

Part B

The speed when the rock hits the ground is approximately 50.96 m/s

Explanation:

Part A

The question is focused on the kinetics equation of a free falling object

The given parameter is the time it takes the rock to hit the ground, t = 5.2 s

For an object in free fall, we have;

h = 1/2·g·t²

Where;

h = The height from which the object is dropped

g = The acceleration due to gravity ≈ 9.8 m/s²

t = The time taken to travel the distance, h = 5.2 s

∴ h = 1/2 × 9.8 m/s² × (5.2 s)² ≈ 132.496 m

The distance travel by the rock, h ≈ 132.496 m

Part B

The speed, 'v', when the rock hits the ground, is given by the following kinematic equation,

v = g·t

∴ v = 9.8 m/s² × 5.2 s = 50.96 m/s

The speed when the rock hits the ground, v ≈ 50.96 m/s.

Answer:

the thermal energy absorbed is 46,893 J

Explanation:

Given;

mass of the water, m = 145 g = 0.145 kg

initial temperature of the water,  t₁ = 23 ⁰C

final temperature of the water, t₂ = 100 ⁰C

specific heat capacity of water, c = 4,200 J/kg.⁰C

The thermal energy absorbed is calculated as;

H = mcΔt

H = 0.145 x 4,200 x (100 - 23)

H = 46,893J

Therefore, the thermal energy absorbed is 46,893J

Answer:

Harish went 1.92 Km in 2 minutes.

Explanation:

Harish is running at 16 m/s (Meters per second) and we need to find how far he goes in 2 minutes.

We can use this formula to calulate the distance:

m/s x time

We know that Harish is going 16m/s so let's plug that in:

16 (m/s) x time

We also should know that 2 minutes is 120 seconds - Let's plug that in too:

16 (m/s) x 120 (Seconds)

Now we calculate:

16 x 120 = 1920

Harish went 1,920 meters in 2 minutes.

Even though we have a correct answer, we can still make it easier to read by converting meters into kilometers.

1 Kilometer (Km) is equal to 1,000 meters.

All we need to do now is divide 1,920 by 1,000 and that will gove us our simplified answer of:

1.92 Km

Answer:

1.92 km

Explanation:

I will explain you:

2×60=120

Explanation:

Answer:

See Explanation

Explanation:

The question is incomplete, as there are no diagrams or options to provide more information to the question.

The general explanation is as follows:

For the object not to move

(1): The forces acting on the object must opposite each other. i.e. if force A acts at the right (or positive direction), force B will act at the left (or negative direction).

(2) The two forces must be equal.

So, for instance:

If the pair of forces are 5N and 5N in opposite directions, the object wil not move.

However, if one of the forces is greater, the object will move towards the direction of the greater force.

Answer: The items listed in the attached file is correctly matched below.

Explanation:

51.) Temperature --> ( Kelvin). This is the correct option as the standard international unit of temperature is measured in Kelvin.

52.) Needle --> ( wedge). An example of a wedge is a needle as they are simple machine designed to make work easier.

53.) Wood --> ( non - magnetic material). This is the correct option as wood can not be attracted by a magnet.

54.) Door knob--> (wheel and axle). The door knob is a type of wheel and axle as it has a wheel portion which is the knob and an axle which is the rod in the door that turns the same axis.

55.) Ramp --> (inclined plane). A ramp is an inclined plane which has a sloping surface.

56.) Like forces --> (repels each other). In an electrostatic field, two charged objects repels each other if they have like forces.

57.) Mass --> ( kilogram). This is the correct option as the standard international unit of mass is measured in kilogram.

58.) Friction --> ( oppose motion). This is correct as friction is the force that poses resistance to a moving object.

59.) Cobalt coin -->( magnetic material). This is the correct option as cobalt coin can be attracted by a magnet.

60.) Lemon crusher --> ( Class 2 lever). This is correct as the lemon (load) is at the middle of the fulcrum ( squeezer) and the effort (hand)

61.) Sew saw -->( Class 1 lever). This is correct as in first class lever type of machine, the fulcrum is in-between the load and the effort.

62.) Wheel and axle --> ( Grooved wheel with rope around)

63.) Unlike forces --> ( attracts each other). In an electrostatic field, two charged objects attracts each other if they have unlike forces ( that is, one is positive and the other is negative).

64.) Earth pulls everything towards --> (Gravitational force). This is correct as stated by Newton's law of universal gravitation. This law states that every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Answer:

B) 5 ft

C) Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick

Explanation:

A) Total distance covered by the dog = 20 + 15

                                  = 35 ft

B) Since the other distance covered by the dog before chewing the stick, after the retrieval, was in an opposite direction to the initial direction, then;

total displacement of the dog = 20 - 15

                                  = 5 ft

C) Net displacement = distance covered by the dog to retrieve the stick + distance covered before the dog starts chewing the stick

But, displacement involves a specified direction. The distance covered before the dog starts chewing the stick was in an opposite direction to the initial direction.

Thus,

Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick
