How big should a mirror be above a fireplace? Ideally the maximum height of the mirror frame should be at least 4″-5″ below a cornice, or 2″ below a picture rail. 3. The mirror frame should not extend beyond the end of the mantelpiece shelf. Where do you hang a mirror over a fireplace? Mirror […]

What is L in double slit equation? the distance between the slits or sources of the two light waves (d) the perpendicular distance from the point P to a point on the central antinodal line (y) the distance from point P to the sources (L) What is Young’s double slit formula? The equation d sin […]

What are the phases of a star? Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 – A region of condensing matter will begin to […]

Why does cooking oil have a higher boiling point than water? So when I say that oil has a higher boiling point than water, what I am actually saying is that the chemical bonds that hold oil together are stronger than the ones holding water together – it takes more heat to break them apart. […]

How fast is a light year? In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km). Why do we use light years to measure distance […]

What is an example of a stationary object? For example, a heavy bag resting on a bed pushes on the bed because of its downward weight force and the bed pushes back up on the bag with a balancing force as it is squashed under the load. What is the force of a stationary object? […]

What type of electromagnetic waves is used in radar? Radar uses radio waves which are electromagnetic waves and travel at a speed of 300,000,000 m/s. What are the 2 types of radar? Radars can be classified into the following two types based on the type of signal with which Radar can be operated. Pulse Radar. […]

Which type of resistors are most often used nowadays? Fixed resistors are available in axial leaded and surface mount packages as well as more customized packages depending on their application. While axial leaded resistors used to be the most used resistors, nowadays the advantages of surface mount devices make the SMD resistors the most popular. […]

What is a mesocyclone Brainly? A rapidly rotating air mass within a thunderstorm that often gives rise to a tornado. What is one of the conditions necessary for a thunderstorm to develop? There are three basic ingredients needed for thunderstorm development: moisture, an unstable atmosphere, and some way to start the atmosphere moving. What are […]
