Answer 1
Answer:

Surface winds on Earth are primarily caused by differences in Air density due to unequal heating of Earth's surface. The answer is letter A. Surface currents are driven by winds that blow in certain patterns. They are caused by the Earth’s spin and the Coriolis effect. Evaporation adds water to the atmosphere. It is the change from liquid to gas wherein liquid molecules tends to go the gas phase and increases the number of molecules. 

Explanation:

Causes of Different Pressure on the Earth's Exterior. Differences in pressures across the cover of the Earth are fundamentally produced by irregular heating of the surface by the Sun.
Answer 2
Answer:

Final answer:

Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. The Hadley circulation and the Coriolis effect influence the direction and patterns of these winds.

Explanation:

Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. When the sun's rays hit the equator, the air at this latitude becomes heated and rises, creating an area of low pressure. This causes air from cooler, higher pressure areas to flow towards the equator, resulting in surface winds.

This circulation pattern is known as the Hadley circulation and is responsible for the trade winds, which blow from east to west near the equator. Similarly, the temperature differences between the poles and the equator create the polar easterlies and the prevailing westerlies.

As the Earth rotates on its axis, the Coriolis effect comes into play, causing the wind to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is why trade winds blow from east to west and prevailing westerlies blow from west to east.

A piston above a liquid in a closed container has an area of 1m2. The piston carries a load of 350 kg. What will be the external pressure on the upper surface of the liquid?

Answers

Pressure is defined as the force exerted per unit of area. From the information given, the force exerted can be attributed to the mass of the load carried by the piston. This means that its weight is equivalent to the force it exerts.

Weight = mass(9.81) = 3433.5 Newtons
Area of piston = 1 m^2
Pressure = Force/Area = 3433.5/1 = 3433.5 N/m^2 or Pascals.

In the modern quantum-based atomic theory, what is the name given to a particular space around the nucleus in which an electron moves?

Answers

In the modern quantum based atomic theory, the name given to a particular space around the nucleus in which an electron moves is called orbital. You might be interested to know a little more about the term orbital. Atomic orbital is actually a mathematical function that describes the wave like nature of a single electron or a pair of electrons within an atom.

Answer:

When the orientation of the Moon is just right, the high tides from the lunar bulge and the solar bulge line up, causing a very strong "Spring tide" --- an especially high high tide and a very low low tide. At what Moon phase(s) will you see a Spring tide?

Answers

Answer:

The correct answer is we see a Spring tide just after a full moon or no moon phase i.e. twice each lunar month.

Explanation:

A spring tide is popularly known as the "King Tide". As the name suggest, it has nothing to do with the season of spring. It gets its name from the idea of "springing forth". During a spring tide, the tidal range i.e. the difference between high and low water, is maximum. This happens when sun and the moon are on the same side of the earth (new moon) as well as when sun and moon are on the opposite side of the earth (full moon).

How does inertia affect a person who is not wearing a seatbelt during a collision?

Answers

A person who is not wearing a seatbelt during a collision will be thrown forward because it maintains forward motion

Further explanation

In Newton's law, it is stated that if the resultant force acting on an object of magnitude is zero,  it can be formulated :

\large{\boxed{\bold{\Sigma F = 0}}}

then the object tends to defend itself from its state. So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called inertia

The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.

In objects with mass m that move translatively, the object will maintain its linear velocity

When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal accidents or collisions.

The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.

Explanation:

The inertia of a body is a property contained by the body by virtue of its mass. Higher the mass of a body, higher will be the inertia.

According to the Newton's first law of motion i.e. law of Inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body to change its state.

When a car is moving on a road, the car is in motion and the body of the person in the car is also in the motion along with the car. Now if the car faces any collision, the car will suddenly come to rest.

But the body of the person sitting in the car continues to be in motion as there is no external force acting on the body. If the person is not wearing the seat-belt, the body moves forward and the person may hit the dashboard very hard.

The seat-belt stops the person's body to move ahead and hit the dashboard. So, the seat-belt prevents the person from injury by stopping the body.

Thus, The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.
