What is the total mechanical energy of a rock falling off a cliff at a time when its potential energy is 500 J and its kinetic energy is 600 J?
The total mechanical energy of the rock is the sum of its potential energy and kinetic energy. In this case, the total mechanical energy would be 1100 J (500 J + 600 J).
A pendulum has a kinetic energy of 65 J and a gravitational potential energy of 78 J. What is its mechanical energy?
The mechanical energy of the pendulum is the sum of its kinetic energy and gravitational potential energy. Therefore, its mechanical energy is 65 J + 78 J = 143 J.
What is the energy of a photon that emits a light of frequency 4.47X 1014 Hz?
2.96 x 10^-19 J
What will be the kinetic energy of an arrow having a potential energy of 50J after its shot from a bow?
Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.
What is the energy of a photon that emits a light of freqeuncy7.21x1014hz?
The energy of a photon is given by the equation E = hf, where E is the energy, h is Planck's constant (6.63x10^-34 J-s), and f is the frequency of the light. Plugging in the values, the energy of the photon is approximately 4.78x10^-19 joules.
What is the efficiency formula?
Efficiency=Useful energy output divided by the energy input. i.e. 100 J is the energy input and you get 5 J light energy from a lamp, the waste energy would be 5 J.
What is the energy of 405 nm light in joules?
Each photon has an energy of 4.9*10^-19 J.
The light reactions of photosynthesis convert what energy to what energy?
During photosynthesis plants transform light energy from the sun to chemical energy.
Is there a science word that has to do with light or sound that starts with j?
There are very limited science words that start with J and none of them are related to light and sound. However, aÊjoule is a unit of electrical, mechanical, or heat energy.
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?
18,000 J
What is the energy of a photon the emits a light of frequency 6.42 1014 Hz?
4.25 10-19 j
What is the energy of a photon of green light with a frequency of 5.89 1014 s-1?
The energy of a photon is given by E = hf, where h is Planck's constant (6.626 x 10^-34 J·s) and f is the frequency. Plugging in the values, the energy of a photon of green light with a frequency of 5.89 x 10^14 s^-1 is approximately 3.48 x 10^-19 Joules.
What is the energy J of photon with a wavelength of 601nm?
The energy of a photon can be calculated using the equation E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Plugging in the values, we get E = (6.626 x 10^-34 J s * 3.00 x 10^8 m/s) / 601 x 10^-9 m. Solving this will give you the energy of the photon.
