Explanation:

Every 15 degree eastwards the time is 1 hour later so that when it is 2 pm in london, it is 8 pm in dhaka. at this time, what do the clocks in manila say 10 pm.

Based on the given information, we know that London is at 0 degrees longitude and Dhaka is at 90 degrees east longitude. Therefore, the time difference between London and Dhaka is 6 hours (15 degrees eastwards = 1 hour later, so 90 degrees eastwards = 6 hours later).

If it is 8 pm in Dhaka, then it would be 2 pm in London - this is the time difference we already know.

To find out what the time in Manila is, we need to know its longitude. Manila is located at approximately 120 degrees east longitude.

Every 15 degrees eastwards from London means an hour later, so we can calculate the time difference between London and Manila as follows:

- London to Manila is 120 degrees eastwards from London
- 120 divided by 15 is 8
- Therefore, the time difference between London and Manila is 8 hours

If it is 2 pm in London and the time difference between London and Manila is 8 hours, then the time in Manila would be 10 pm.

Therefore, the clocks in Manila would say 10 pm at this time.

Monopolistic competition is separated from pure or perfect competition by product differentiation.

In a monopolistically competitive market, firms produce differentiated products, which means that each firm has some degree of market power to charge a slightly higher price than competitors. This differs from perfect competition, where all firms produce identical products and have no market power.

Hope that helps! Good luck! :)

Monopolistic competition is separated from pure or perfect competition by product differentiation. In pure or perfect competition, all firms in the market produce homogenous goods and have no control over the price.

On the other hand, monopolistic competition has firms that produce slightly different products, and they have a certain level of control over the price of their products. This is because consumers may be willing to pay more for a particular product, even if it is similar to another.

Moreover, in monopolistic competition, firms have a profit motive, which drives them to produce the best possible product and to be efficient in their production. Inadequate competition and oligopolies are characteristics of other market structures such as monopolies and oligopolies, respectively.

In conclusion, product differentiation is the main characteristic that distinguishes monopolistic competition from pure or perfect competition. This differentiation allows firms to have some control over price and to strive for profits, which is not the case in pure or perfect competition.

Explanation:

a. A price floor is a government-imposed minimum price that is set above the equilibrium price of a good or service in a market. The minimum wage is an example of a price floor, as it sets a minimum wage rate that employers must pay to their workers. Therefore, the minimum wage is a specific type of price floor.

b. Rationing is a system of allocating scarce resources, such as food or fuel, based on a set of criteria or rules. In times of shortage, a black market may emerge, which is an illegal market in which goods or services are bought and sold at prices that are higher than the legally established price. Rationing and black markets are related because they both arise as a response to scarcity, but they represent two different ways of allocating resources. Rationing is a legal and controlled method of allocating scarce resources, while black markets are illegal and uncontrolled.

A river or stream cutting through existing rock strata to create a new route for the water to travel is referred to as superimposed drainage. When the land's surface is raised or when the river's base level falls, this process can take place.

Unless there is a considerable change in the topography, a river or stream is unlikely to change its course once it has made a new passage through the rock strata. This is due to the fact that the structure and makeup of the rock strata, as well as the slope of the ground, both affect the river's course. Even while the river could wash away the rocks over time, it is unlikely that it will alter its path until the slope or make-up of the terrain significantly changes.

For instance, if the ground falls or is elevated, the land's slope may vary, changing the river's flow. The river, even if it is overlaid on top of preexisting rock strata, is likely to continue running along its established course if the ground is stable.

answer: it would have 6.28 square feet

Answer:

Warm temperature at sea surfaces.

Coriolis force impact area that forms a low-pressure zone.

Atmospheric instability.

Increased humidity in the lower to middle levels of the troposphere.

Low vertical wind shear.

Explanation:

Warm, moist air over the ocean rises due to less density. This air rises up and away from the ocean surface, leaving less air near the surface, creating a low-pressure zone.

Due to the surrounding high-pressure areas, air flows into this low-pressure area and eventually warms up, forming a cycle.

Now, this cycle makes the warm air above the ocean rise and cool the water below to generate clouds. With the constant heating and evaporating process, the entire cloud and wind system spins and grows.

With more speed, cyclone eye formation takes place in the centre. This zone signifies the lowest air pressure and is calm and clear. The high-pressure air from above flows down into this region.

When the wind’s rotating speed reaches 63 kmph, it is called a tropical storm. However, when wind speed reaches 119 kmph, tropical cyclone formation takes place.

Now that you know how a cyclone is formed, let's look at the categories of a cyclone.

To produce a commercially viable oil deposit, there must be a source rock, a reservoir rock, a seal rock, and a trap that denies the oil passage to the surface.

The source rock is typically a sedimentary rock rich in organic materials, which under heat and pressure, generate hydrocarbons like oil and gas. The reservoir rock is a porous and permeable rock that stores the hydrocarbons, allowing them to flow through its interconnected pore spaces. Common reservoir rocks include sandstones and limestones.

The seal rock is an impermeable layer that prevents the hydrocarbons from escaping and migrating to the surface. Seal rocks, often made of shale or mudstone, create a barrier that keeps the hydrocarbons within the reservoir rock. Lastly, the trap is a crucial geological feature that stops the oil from reaching the surface. Various types of traps can be found, including structural traps (formed by deformation, such as folds and faults) and stratigraphic traps (created by changes in rock properties like permeability).

Together, these elements make up a complete petroleum system, which is necessary for the formation of a commercially viable oil deposit. Without any of these components, the oil may not accumulate in significant quantities, or it may not be economically feasible to extract it.

Therefore the correct answer is a trap that denies the oil passage to the surface.

Explanation:

The particles of sediment that are most likely to be transported as suspended load are small, low-density particles. These particles have a small enough size and low enough density to be easily carried along by the flow of water or air without settling out too quickly.

Pebbles of average density (Option B) are too large and heavy to be transported as suspended load. Instead, they are typically transported as bed load or rolled along the bottom of a river or stream.

Sand and gravel of relatively high density (Option C) can be transported as suspended load in very fast-moving water, such as during floods or other high-energy events. However, they are more likely to be transported as bed load.

Dissolved ions in solution (Option D) are not considered sediment and are transported as part of the water itself, not as suspended load.

Therefore, the correct answer is Option A: small, low density particles.

All of the mentioned answers are advantages of sustainable farming including less water pollution, not killing of insects and preventing soil degradation for the farmer/environment. The right answer is d.
