Why red is more energetic than yellow? Since, red light has lower frequency than yellow, yellow has higher momentum than red, not mass. In a way, it’s the momentum of photons which cause the radiation pressure. If the hotter an object, the brighter it glows (more energy), then why is a blue flame less visible […]
What is the difference between solar time and solar day?
What is the difference between solar time and solar day? The sidereal day is measured with respect to the stars, while the solar day is the length of time measured from noon to noon. By noon, we mean the time when the Sun passes the celestial meridian, reaching its maximum height in the sky. How […]
What are the steps in set and drift?
What are the steps in set and drift? Set and drift are two terms used to describe the effect currents have on your boat…. Find the distance to your destination in nautical miles. Divide this distance by your average speed in knots. Multiply this time by the average speed (drift) of the current. From your […]
Where does etc occur?
Where does etc occur? Steps of the ETC The electron transport chain occurs across the inner mitochondrial membrane. Its main function is to build an electrochemical gradient across the inner membrane using protons. The ETC pumps hydrogen ions out of the matrix of the mitochondria and into the intermembrane space. What is the main purpose […]
Why are the intestines shorter in a living person than in a dead person?
Is damped oscillation?
Is damped oscillation? An oscillator is anything that has a rhythmic periodic response. A damped oscillation means an oscillation that fades away with time. Examples include a swinging pendulum, a weight on a spring, and also a resistor – inductor – capacitor (RLC) circuit. What causes damped oscillation? a decrease in intensity of oscillations with […]
Does photoelectric current depend on frequency?
Does photoelectric current depend on frequency? Photoelectric effect can be explained as: it takes a specific energy to launch an electron from a metal surface. This energy is the work function which relies upon the metal. Electrons can pick up energy by collaborating with photons. Current is not dependent on the frequency of photons. What […]
What are the advantages and disadvantages of coal power?
What are the advantages and disadvantages of coal power? Coal energy is an affordable energy source because of the coal’s stable price compared to other fuel sources. Coal is easy to burn. Coal produces high energy upon combustion. Coal energy is inexpensive. Why should we not use coal? In 2012, coal accounted for 37.4% of […]
How do you arrange negative numbers in ascending order?
How do you arrange negative numbers in ascending order? Arrange the following integers in ascending order, putting the smallest first. Look at the negative numbers first. The smallest negative number is -35, then -2. Then look at the positive numbers. How are numbers arranged in increasing or decreasing order? Suppose for example, 81, 97, 123, […]
