The equation for the energy (E) of the electron may be obtained by the equation,
E = hc / λ
where h is Planck's constant, c and λ are speed of light and wavelength, respectively. Substituting the values,
(-2.179x10^-18 - -8.720x10^-20) = (6.626x10^-34)(2.998x10^8)/ λ
From the equation, the value of λ is approximately equal to 9.496x10^-8 m.
Answer:
Well, to me that person was really and very very different from me.
I didn't met that person by person, but I felt like I was a very happy person,
It did, but it kinda went down.
But I'm always ready to fix it.
Hope it helps.(ツ)
Explanation:
That`s is the answer, just check
Answer:
The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg.
Answer:
Final speed, v = 28.81 m/s
Explanation:
Given that,
Mass of the car, m = 1423 kg
Initial speed of the car, u = 26.4 m/s
Force experience by the car, F = 901 N
Distance, d = 106 m
To find,
The speed of the car after traveling this distance.
Solution,
The force experienced by a car is equal to the product of mass and acceleration.
Let v is the final speed of the car. Using third equation of motion to find it as :
v = 28.81 m/s
So, the final speed of the car is 28.81 m/s.
