Calculate the work function that requires a 475 nm photon to eject an electron of 1.25 eV.

lapo4ka [179]

The work function has the formula
E = h v

where
E is the energy
h is the constant
v is the frequency

Since the given is wavelength, we use the relationship between frequency and wavelength
v = c / λ
where
c is the speed of light
λ is the wavelength

So.
E = h c / λ
h = Eλ / c = 1.25 eV (475x10-9m) / (3x10^8 m/s)
h = 1.9792 x 10^-15

The work function is:
E = 1.9792 x 10-15 v

Define liquid pressure

Stella [2.4K]

The pressure of a liquid on the surface of its container or on the surface of any body in the liquid is equal to the weight of a column of the liquid whose height equals the depth of the liquid at that certain point.

A punter wants to kick a football so that the football has a total flight time of 3.7 s and lands 56m away (measured along the g

Irina18 [472]

The maximum height is 16.8 m

Explanation:

In order to find the maximum height reached by the football, we can just analyze its vertical motion.

The vertical motion of the ball is a free fall motion, affected only by the force of gravity. So it is a uniformly accelerated motion, and we can use suvat equations.

First of all, we notice that the motion of the ball is symmetrical, so the time taken to reach the maximum height is equal to the time needed to fall down: Since the total time of flight is

T = 3.7 s

It means that the time to reach the maximum height is

$t=\frac{T}{2}=\frac{3.7}{2}=1.85 s$
