Answer and Explanation:
The answer is attached below
Explanation:
Well it depends on what type of energy all plants produce energy for them to survive but if its a certain energy your looking for make sure to put it in you quesion
The pendulum movement is a famous situation manifesting the force of tension by the rope and the force of gravity coming into play. There are already derived equations explaining the behavior of the pendulum movement.
Period = t = 2π√(L/g)
Since, we don't have exact values for the parameters, let's just find the ratio to provide comparison. Let's find the ratio of the pendulum on the moon (t,moon) to the period of the pendulum on earth (t,earth).
t,moon/t,earth = 2π√(L/g/6) ÷ 2π√(L/g) = √6
Therefore, the period of the pendulum on the moon is the square root of 6 times that of in the earth.
Answer:
1 eV
Explanation:
Given:
Work function, ∅ = 2.00 eV
Kinetic energy of the ejected of the electron, K.E = 4.0 eV
Now,
using the photoelectric equation
, we have
Energy of the photon (E) = ∅ + K.E
also,
E = hc/λ
where, h is plank's constant
c is the speed of the light
λ is the wavelength
thus, we have
hc/λ = 2 + 4 = 6 eV
Energy of photon = 6eV
Now,
for the second case
λ' = 2λ
when Wavelength is doubled , E is halved
thus,
E' = hc/λ'
or
E' = hc/2λ
or
E' = E/2 = 6/2 = 3 eV
also,
E' = ∅ + KE
'
thus on substituting the values,
3 = 2 + KE'
or
KE' = 1 eV
Hence, the maximum kinetic energy for the second case is 1 eV
