Answer:

v=u+at

15=10+a x 5

15-10= 5a

5= 5a

a=1 m/sec^2

A neutron has a kinetic energy of 10 MeV. What size aperture would be necessary to observe diffraction effects?
Sedaia [141]

Answer: 9.33fm

Explanation:

Similarly as with a cut diffraction happens when part of the proliferating wave is cut off. This will occur for any object of request with a similar size as the wavelength of the diffracting wave.

Note, the object is moving at 14% of the speed of light. Be that as it may, the gamma factor is just 1% so taking care of the issue either relativistic or non relativistic conditions offers comparative responses.

Note: The size of the object has to be of the order of the wavelength of 10MeV. Therefore, size apperture that would be necessary to observe diffraction effect would be 9.33fm.

The calculations are in the attachment below:

A quarterback throws releases a 400. g football 1.2 meters off of the ground with a speed of 25 m/s. Determine the total energy
Usimov [2.4K]
Kinetic energy is an expression of the fact that a moving object can do work on anything it hits; it quantifies the amount of work the object could do as a result of its motion. And potential energy <span>is the </span>energy<span> that is stored in an object due to its position relative to some zero position. </span><span> We calculate as follows:

KE + PE = mv^2 / 2 + mgh 
Total energy = .4(25)^2/2 + .4(9.81)(1.2)
Total energy = 129.71 J = 130 J <------- OPTION A</span>
