To raise 1 kg by 1C, it will take 129 joules.
To raise 0.015 kg by (85-22)C, it will take (129*0.015)*22 = 42.57 joules.
Which of the following pairings are more likely to be held together with the strong nuclear force
Explanation:
1.What does a strong nuclear force do in an atom? It repels electrons from other electrons. It repels protons from other protons. It attracts protons and neutrons.
2.The chain reaction requires both the release of neutrons from fissile isotopes undergoing nuclear fission and the subsequent absorption of some of these neutrons in fissile isotopes.
3.The strong nuclear force holds most ordinary matter together because it confines quarks into hadron particles such as the proton and neutron. In addition, the strong force binds these neutrons and protons to create atomic nuclei.
Answer with Explanation:
We are given that
Diameter of coil=d=0.115mm
Radius, r=
Using 
Electric field=E=0.235V/m

(a).We know that
Substitute the values
(b).Current density,
Using the formula
c.Total current,I=JA
Where 
Using the formula
I=0.076A
d.Length of wire=l=2m
Substitute the values
