Answer:
Explanation:
The sense of weightlessness in orbiting satellite is because of the lack of any contact-forces. ... Thus, both the astronaut and the satellite have the same value of g, which is again equal to the centripetal acceleration of the satellite. These two neutralize each other, causing everything to appear weightless.

Answer:
the ratio of protons to neutrons
Explanation:
Nuclear stability is based on the ratio of protons to neutrons. The nuclear space is made up of protons and neutrons that occupies the nucleus of an atom.
For every atomic nucleus, there is a specific neutron/proton ratio which ensures the stability of the nucleus.
For sodium, Na, the neutron/proton ratio for stability is 12/11.
Any nucleus with a neutron/proton combination different from its stability ratio will be unstable.
Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. Explanation:
mass = 177 x 1.0 g/mL= 177 g mass ethanol = 177 x 10.6/100 = 18.8 g moles = 18.8 g/46.069 g/mol = 0.408 1367 kJ/mol x 0.408 mol= 557.9 kJ
The answer would be A, because power is defined as the rate of doing work. Hence power = work / time then you obtain watts. Work is the product of force and displacement (distance). Hence in formula, w = F x s.
