Answer:
g, downward
Explanation:
It is given that, a baseball is thrown straight upward. The force acting on the stone is force of gravity. It is moving under the action of gravity. We know that the force of gravity always acts in a downward direction.
At the highest point, the velocity of the stone will be equal to 0. It will move will constant acceleration equal to g and it always acts in downward direction.
Hence, the correct option is (e) "downward direction".
Answer:
Applying 200 N of force to the chair from the right
Explanation:
Answer:
part a: 4.25s
part b: 180.625m
Explanation:
part a:
what we know: vi=42.5m/s
t=?
vf=0
g= -10m/s^2
----------------------------------------------------------
equation: vf-vi/g=t
plug in: -42.5m/s/ - 10m/s^2 = 4.25s
-----------------------------------------------------------
part b: 42.5m/s x(times) 4.25s = 180.625m
Explanation:
Effective nuclear charge is defined as he net positive charge experienced by an electron in an atom. It is termed "effective" because the shielding effect of electrons prevents higher orbital electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner-layer electrons.
The 1s is the closest shell to the nucleus of an therefore maximum nuclear charge is experienced. The formula for effective nuclear charge is:
Zeff = Z – S
where
Z = the number of protons in the nucleus, and
S = the shielding constant, the average number of electrons between the nucleus and the electron.
Hence, the energy required to remove an electron from the 1s orbital is the strongest.
