What is the meaning of external development? External growth (also known as inorganic growth) refers to growth of a company that results from using external resources and capabilities rather than from internal business activities. The main advantage of external growth over internal growth is that the former provides a faster way to expand the business. […]

How many types of frequency are there? Wavelength: ELF EXTREMELY LOW FREQUENCY Frequency: 3 KHz to 30 KHz Wavelength: 100 km to 10 km HF HIGH FREQUENCY Frequency: 3 MHz to 30 MHz Wavelength: 100 m to 10 m VHF VERY HIGH FREQUENCY Frequency: 30 MHz to 300 MHz Wavelength: 10 m to 1 m […]

How many car lengths should you leave? Figure one car length for every ten miles an hour,” Barndt said. “So if you’re doing 55 miles an hour you should have six car lengths between you so that if something happens to the car in front of you, you have time to stop or react.” The […]

Which has the longest wavelength Brainly? Red Which color has the shortest wavelength Brainly? violet Which color has the highest frequency the shortest wavelength? Violet Does light vibrate at a low frequency? Our eyes perceive different wavelengths of light as the rainbow hues of colors. Red light has relatively long waves, around 700 nm long. […]

How do huge stars die? All stars eventually run out of their hydrogen gas fuel and die. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. Why do most stars […]

What is gravitational potential energy in simple words? Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object. What is the meaning of gravitational potential? The gravitational potential at […]

What is the advantage of PIN photo diodes? Advantages and Disadvantages of PIN Photodiode The advantage is its high-frequency response and its frequency response is also greater than Cadmium – Sulphide photodetector. It is inexpensive and the response time is in nanoseconds which make it appropriate for electronic circuitry. What are PIN diodes used for? […]

Is thermal energy removed or added in boiling? particles, rise to the top of the liquid and escape from the container. In the graph above, notice the energy changes that occur as thermal energy is added. The kinetic energy of particles increases until the liquid reaches its boiling point. At the boiling point, the potential […]

When discussing magnetic fields we could say that 2 points? When discussing magnetic fields we could say that metals can become magnetic if they have many spinning electrons that create magnetic fields. metals are magnets because they have more electrons than non–magnetic materials. non–paired electrons spin in opposite directions creating a magnetic field. What are […]

Is it normal to hate roller coasters? While roller coasters are a popular theme park attraction, certain people feel nauseated, afraid, dizzy, or unsafe when riding roller coasters. In many cases, this fear is related to other phobias – such as acrophobia, claustrophobia or emetophobia – a condition like vertigo, or to a traumatic event. […]
