Answer: cold and warm air masses interact in an unstable environment.
Explanation: Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to heavy gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone .According to the polar-front theory, extratropical cyclones develop when a wave forms on a frontal surface separating a warm air mass from a cold air mass. As the amplitude of the wave increases, the pressure at the centre of disturbance falls, eventually intensifying to the point at which a cyclonic circulation begins. The decay of such a system results when the cold air from the north in the Northern Hemisphere, or from the south in the Southern Hemisphere, on the western side of such a cyclone sweeps under all of the warm tropical air of the system so that the entire cyclone is composed of the cold air mass. This action is known as occlusion.Extratropical cyclones arise through a process called cyclogenesis, in which cold and warm air masses interact in an unstable environment.
Answer:
Explanation:
Variable MOH rate variance = Actual Hours × (Actual Rate - Standard Rate)
= 4050 × ($7.50 - $4.50)
= 12150
Answer:
The answer is $75
Explanation:
The formula to reach out value addition is
Value Addition=Sales Value-Cost of manufacture or input added
In our Case
Sales Price=$450
Cost of Manufacture or Input=200+75=$275
So by entering above numbers in Value Addition formula we get
Value Addition=$450-$275
Value Addition=$175
Answer:
General overhead= $3.81 per direct labor hour
Explanation:
Given the following information:
General Overhead $80,000 Number of direct labor hours
Number of direct labor hours 9,000 12,000= 21,000
<u>To calculate the activity rate, we need to use the following formula:</u>
Activity rate= estimated costs / total amount of allocation rate
General Overhead= 80,000 / 21,000
General overhead= $3.81 per direct labor hour
