What expression gives the amount of light energy (in J per photon) that is converted to other forms between the fluorescence exc

itation and emission events?
Physics
1 answer:
erastovalidia [21]3 years ago
8 0

Answer:

E = hf or E=\dfrac{hc}{\lambda}

Explanation:

The expression that gives the amount of light energy that is converted to other forms between the fluorescence excitation and emission events is given by :

E = hf

f is the frequency

E=\dfrac{hc}{\lambda}

c is the speed of light

\lambda is the wavelength

Hence, this is the required solution.

7. Reid runs away from Joharri after an intense political debate. His initial acceleration is
disa [49]

Answer:

0.6944 m/sec^2

Explanation:

The computation of the average acceleration is given below:

a = v - u ÷ t

where

a denotes average acceleration

v denotes final velocity

u denotes initial velocity

t denotes time

So, the average acceleration is

= (25 - 0) ÷ 10

= 0.6944 m/sec^2

Why does the vertical component of velocity for a projectile change with time, whereas the horizontal component of velocity does
dlinn [17]

Answer

When a body moves in projectile motion it has two components. One of the components is a horizontal component of the velocity and another is a vertical component.

The velocity along the horizontal component does not change because there is no acceleration long horizontal component.  

Whereas velocity along vertical direction keeps on changing because the acceleration due to gravity is acting on the object. At a maximum height of the projectile velocity is equal to zero.

A thin, 100 g disk with a diameter of 8.0 cm rotates about an axis through its center with 0.15 J of kinetic energy. What is the
butalik [34]

Answer:

v=2.45 m/s

Explanation:

The rotational kinetic energy is calculated with:

K=\frac{I\omega^2}{2}

The moment of inertia of a disk is:

I=\frac{mr^2}{2}

A point on the rim of a disk will have a speed of:

v=r\omega

Putting all together:

v=r\sqrt{\frac{2K}{I}}=r\sqrt{\frac{2(2K)}{mr^2}}=2\sqrt{\frac{K}{m}}

Which for our values is:

v=2\sqrt{\frac{0.15J}{0.1Kg}}=2.45m/s

In which collision scenario is the difference in total momentum before and total momentum after the collision the greatest?
Hitman42 [59]

Answer:

The law states that when two objects collide in a closed system, the total momentum of the two objects before the collision is the same as the total momentum of the two objects after the collision. The momentum of each object may change, but the total momentum must remain the same.
