Answer:
Faults are found in collisions zones, and tectonic plates push up against mountain ranges for example the Himalayas or the Rocky Mountains.
Explanation:
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
Observation: You saw/ observed something and you are stating that.
Inference: You are predicting something to be true. If so and so, then this will occur.
Answer:
A) r= 4081.63m
B) Fc= 519.205 kN
Explanation:
Given
A)
The radius of the circle is:
B)
The centripetal force
C)
The force of lift according to Bernoulli law the force of lift is equal to the force make the F-14 jet flying
Equation:
p=density of the air in the moment the jet in flying ≅1-1.5 and the area is going to be the area of the wings where is the force of lift acting have to be more that Fc
An inclined plane has less of a mechanical advantage because it has to have more work to take so,etching up than down. I hope this makes sense.
