Which interaction between x-ray photons and matter results in total absorption of the incident photon?
Leno4ka [110]

Answer:

Photoelectric effect        

Explanation:

In the photoelectric effect, when an x-ray strikes on a metal surface, the energy is completely absorbed by the metal. If the energy would be equal to or more than work function of  metal, electron ejects out. The kinetic energy of the electron which is ejected depends on the energy of the incident radiation and work function of the metal.

If a projectile travels in the air for 8 seconds when does a projectile reach its highest point
emmainna [20.7K]

Given

The projectile is in air for a time of t=8 sec

To find

The time it takes to reach the highest point

Explanation

A projectile moves up to the highest point and then again moves down following a parabolic path.

So it will reach the highest point at a time half the time it requires to follow teh parabolic path.

The time taken to reach the highest point is 4 sec

Conclusion

The time taken is 4 sec.

The force of repulsion between to like charge table tennis balls is 8.2 X 10 ^-7 N if the charge on the two objects a 6.7 X10^-9
Svetllana [295]

Answer:

0.702 m

Explanation:

The magnitude of the electrostatic force between two charged objects is given by Coulomb's Law:

F=k\frac{q_1 q_2}{r^2}

where

k is the Coulomb's constant

q1, q2 are the two charges

r is the separation between the objects

And the force is:

- Attractive if the two charges have opposite signs (+-)

- Repulsive if the two charges have same sign (++ or --)

In this problem we have:

F=8.2\cdot 10^{-7}N is the force between the two balls

q_1 = q_2 = 6.7\cdot 10^{-9}C is the charge on each ball

Solving for r, we find the separation between the balls:

r=\sqrt{\frac{kq_1 q_2}{F}}=\sqrt{\frac{(9\cdot 10^9)(6.7\cdot 10^{-9})^2}{8.2\cdot 10^{-7}}}=0.702 m
