Weight = mass × gravity
W = 50 kg * 10.5 m/s^2
W = 525 kg * m/s^2 or 525 N
hope this helps :)
protons and nuetrons are all attracted to each another as the result of the strong nuclear force
Answer:
Explanation:
Work done = Force * Displacement
There is no displacement vertical so only the horizontal part of force did work.
The horizontal force = Force * cos(angle with floor)
Work done = 40*cos(40°)*2
= 61.28 J
As cos(65°) is less than cos(40°), work done will be less at 65°.
Chemical nomenclature .... I believe this is right
