Aproton and an alpha particle (helium nucleus consisting of two protons and two neutrons) are accelerated from rest across the same potential difference. assume the proton mass and the neutron mass are roughly the same and neglect any relativistic effect. compared to the final speed of the proton, the final speed of the alpha particle is? 1. less by a factor of 22. less by a factor of √ 23. less by a factor of 44. greater by a factor of 25. the same

option B

Explanation:

we know,

change in energy is equal to

proton mass and the neutron mass are roughly the same

so,

now,

we know,

mass of alpha particle is four times mass of the mass of proton. 

mα = 4 m_p

less by a factor of √2

Hence, the correct answer is option B

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
