What is effect of intensity of light? Intensity cannot change the cut off frequency or stopping potential. High intensity means more number of photons, so chances of hitting to electron by them increase and hence more photo electron are emitted i.e., photo current increases. Why intensity decreases as distance from the light source increases this […]
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 […]
Can electrons exist alone?
Can electrons exist alone? Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well. What happens to the atoms […]
What is the relationship between temperature and kinetic energy answers?
What is the relationship between temperature and kinetic energy answers? Kinetic energy is directly proportional to the temperature applied. Basically with increase in temperature the vibration / collision of molecules increase hence kinetic energy increases. What is the relationship between the kinetic energy of molecules in an object? Explanation: The kinetic energy of the molecules […]
What are 5 scientific laws?
What are 5 scientific laws? What are the five scientific laws? The five most popular scientific laws are Hooke’s Law of Elasticity, Archimedes’ Principle of Buoyancy, Dalton’s Law of Partial Pressures, Bernoulli’s Law of Fluid Dynamics and Fourier’s Law of Heat Conduction. Do scientific laws and legal laws have anything in common? Scientific laws may […]
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 […]
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, […]
Why red is more energetic than yellow?
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 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 […]
