Acceleration = (change in speed) / (time for the change)

Change in speed = (ending speed) - (starting speed)

Change in speed = (20 m/s) - (10 m/s)  

Change in speed =  10 m/s

Acceleration = (10 m/s) / (5 sec)

Acceleration = <em>2 m/s² forward</em>

Answer:

a = 2 m/s²

Explanation:

average acceleration = change of velocity / change of time

a = Δv/Δt = (20 - 10) / 5 = 10/5 = 2

What is the energy of photons emitted by the led at a frequency of 610 thz mcat?
Ksju [112]

The photon energy is the energy carried by a single proton.

The equation used for calculating photon energy is:

E = hc / λ

where h = Planck constant 

c  = speed of light and

λ = wavelength of photon

frequency = f = c / λ

replace c /λ with f in the equation of photon energy

E = hf

frequency = 610 thz = 6.1 x 10¹⁴hz

h = 6.26 x 10⁻³⁴ js

E = 6.26 x 10⁻³⁴ x 6.1 x 10¹⁴

<span>E = 3.8 x 10</span>⁻¹⁹ j
