Answer:
0.02
Explanation:
Force, where N is normal reaction and coefficient of kinetic friction is . Also, N is equivalent to mg ie N=mg where m is mass of an object and g is acceleration due to gravity. Making the subject of the formula then
Substituting F with 2 N, m with 10 kg and g with 9.81 then
Answer:
I believe that is A. Inclined plane
Explanation:
<span>Answer: 124eV
Explanation: Apply Planck - Einstein Relation to calculate the energy of an X-Ray photon that has a frequency of 3.00 x 10^16 Hz and the energy of a photon is proportional to its frequency
E= hv
where E - the energy of the photon
h - Planck's constant, equal to 6.626 x 10^-34 Js
v - the frequency of the photon
and 1 Hz is equal to 1 s^-1
Thus E= 1.988 x 10^-17J
Now convert the energy of photon from joules to eV
Therefore we get 1.988 x 10^-17J x ( 1 eV / 1.6022 x 10^-19 J)
= 124 eV.</span>
