Answer: In ocean, the less denser warm water due to the heat from the sun, rises up to the ocean surface and tends to move towards higher latitudinal areas. The wind generates the ocean currents and it slowly loses heat and becomes cold and denser as it approaches the polar region and then it sinks down, moves back towards the equatorial region. This constant motion of these water current in the ocean is known as the convection current.

      In the atmosphere, similar mechanism occurs. the air gets warm due to the heating of the sun and rises up to the atmosphere and as it rises up, it slowly becomes dense and again at one point it falls back because of its higher density. This continuous motion of air represents the convection current within the atmosphere.

This two phenomenon is the same as the convection that occurs at the earth's mantle, in which the hot molten magma because of its lower density rises up and gets cooled when it reaches the upper part, becoming dense again falls back.

What is statement can most likey be useing in the shock waves of atmoic bomb
Neko [114]

Answer:

The initial energy emission occurs by 80% or more in the form of gamma rays but these are quickly absorbed and dispersed mostly by air in little more than a microsecond, converting gamma radiation into thermal radiation (thermal pulse ) and kinetic energy (shock wave) which are actually the two dominant effects in the initial moments of the explosion. The rest of the energy is released in the form of delayed radiation (fallout or fallout) and is not always counted when measuring the performance of the explosion.

Explanation:

High altitude explosions produce greater damage and extreme radiation flux due to lower air density (photons encounter less opposition) and consequently a higher blast wave is generated.

Father drove 176 km in 7 hours. For the first 92 km, he spent
Verizon [17]

Answer:

28km/h

Explanation:

92km = 4 hours

176 - 92 = 84

84km = 3 hours

84/3 = 28

28km/h

Hopefully this helps you :)

In a research facility, a person lies on a horizontal platform which floats on a film of air. When the person's heart beats, it
anastassius [24]

Answer: 3.48g

Explanation:

here, we will be using conservation of momentum to solve the problem. i.e the total momentum remains unchanged, unless an external force acts on the system. We'll in thus question, there is no external force acting in the system.

Remember, momentum = mass * velocity, then

mass of blood * velocity of blood = combined mass of subject and pallet * velocity of subject and pallet

Velocity of blood = 56.5cm = 0.565m

mass of blood * 0.565 = 54kg * (0.000063/0.160)

mass of blood * 0.565 = 54 * 0.00039375

mass of blood * 0.565 = 0.001969

mass of blood = 0.00348kg

Thus, the mass of blood that leaves the heart is 3.48g

Which phenomenon support only the wave theory of light? Check all that apply
lys-0071 [83]

Answer:

Diffraction and Interference of light support the wave theory of light.

Explanation:

Complete Question

Which phenomena support only the wave theory of light? Check all that apply.

1.reflection

2.refraction

3.diffraction

4.interference

5.photoelectric effect

Solution

There are two theories/schools of thoughts that light possesses wave and particle properties.

The wave properties of light explain that light is made as a result of interactions of electric and magnetic fields, hence, light is regarded as an electromagnetic wave that propagates without the need for a material medium and moves in a direction perpendicular to the direction of the oscillations or direction of the cause/source of the light waves.

Properties that support the wave properties of light are diffraction (ability to navigate or bend around obstacles) and Interference (two light waves can combine or superimpose to form a single resultant light wave with amplitude greater, lower or equal to the amplitudes of the two constituting light waves).

Hope this Helps!!!
