Answer:c=0.213 J/g/K
Explanation:
Given
sample mass
initial temperature of mineral
mass of water
Water initial temperature
Heat capacity of calorimeter =15.3 J/k
Final Temperature is 24.8
let c be the specific heat of mineral
Heat released by mineral sample=heat absorbed by calorimeter and water

Look first for the relation between deBroglie wavelength (λ) and kinetic energy (K):
K = ½mv²
v = √(2K/m)
λ = h/(mv)
= h/(m√(2K/m))
= h/√(2Km)
So λ is proportional to 1/√K.
in the potential well the potential energy is zero, so completely the electron's energy is in the shape of kinetic energy:
K = 6U₀
Outer the potential well the potential energy is U₀, so
K = 5U₀
(because kinetic and potential energies add up to 6U₀)
Therefore, the ratio of the de Broglie wavelength of the electron in the region x>L (outside the well) to the wavelength for 0<x<L (inside the well) is:
1/√(5U₀) : 1/√(6U₀)
= √6 : √5
You fallow the steps to figure out the complete answer of the question.
Answer:
angle of incidence for the second mirror is 55.4 degree
Explanation:
Given data;
Angle between two mirror is 90 degree
Incident angle on first mirror is 34.6 degree
For first mirror
Angle of incidence is equal to angle of reflection
34.6 degree = angle of reflection

Now , for the triangle ABC [from figure]



The angle of incidence for
angle of incidence for the second mirror is 55.4 degree
