Answer:
Infrared photons carry lower radiation energy than the visible light.
Explanation:
- Each photon carries an energy that is directly proportional to its frequency, being this proportionality constant the Planck's constant h.
- So, we can write the energy of a single photon as follows:
- Since there exists an inverse relationship between wavelength and frequency, and infrared radiation has longer wavelengths, this means that its frequency is lower than the one of the visible light.
- So, an infrared photon carries less energy that one of the visible light.
Answer:
Δp = 620 N.s
Explanation:
- Newton's second law, was originally conceived as follows:
- In this way, a net force applied on an object, is equal to the rate of change of the momentum of the object regarding time.
for m= constant, it reduces to F= m*a.
- Replacing in (1) F= 62 N, and Δt = 10.0 s, we can solve for Δp (object's change in momentum) , as follows:
