Answer:
3.71 eV
Explanation:
λ = Wavelength of light = 224 nm = 224 x 10⁻⁹ m
c = speed of electromagnetic wave = 3 x 10⁸ m/s
V₀ = stopping potential = 1.84 volts
W₀ = Work function of the metal = ?
Using the equation


= 5.94 x 10⁻¹⁹
= 3.71 eV
Answer:

Explanation:
F = Force = 
m = Mass of proton = 
t = Time taken = 
Acceleration is given by


The velocity of the proton is 
At point E
- the kinetic energy of the rollercoaster is small compared to the potential energy
- the potential energy is greater than the kinetic energy
- the total energy is a mixture of potential and kinetic energy
<h3>What is the energy of the roller coaster at point E?</h3>
The energy of a roller coaster could either be potential energy, kinetic energy or a combination of both potential and kinetic energy.
Using analogies, the energy of the roller coaster at point E can be compared to a falling fruit from a tree which falls onto a pavement and is the rolling towards the floor. Point E can be compared to the midpoint of the fall of the fruit.
At point E
- the kinetic energy of the rollercoaster is small compared to the potential energy
- the potential energy is greater than the kinetic energy
- the total energy is a mixture of potential and kinetic energy
In conclusion, the energy of the rollercoaster at E is both Kinetic and potential energy,

A mid ocean ridge is a under water mountain range, knowing this what would you say it is most similar to on land? hope this helped!
