When a high-energy proton or pion traveling near the speed of light collides with a nucleus, it may travel 2.5 x 10-15 m before interacting. from this information, find the time interval required for the strong interaction to occur.

Explanation:

It is given that,

When a high-energy proton or pion traveling near the speed of light collides with a nucleus,

Speed of light,

Let t is the time interval required for the strong interaction to occur. The speed is given by :

So, the time interval required for the strong interaction to occur is . Hence, this is the required solution.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
