Aneutron in a reactor makes an elastic headon collision with the nucleus of an atom initially at rest. assume: the mass of the atomic nucleus is about 14.8 the mass of the neutron. what fraction of the neutron’s kinetic energy is transferred to the atomic nucleus? 017 (part 2 of 2) 10.0 points if the initial kinetic energy of the neutron is 2.66 × 10−13 j, find its final kinetic energy. answer in units of j.

that would be b i just took the test : )

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
