Answer:
Atoms with a low electronegativity, like lithium, have a weak attractive force for electrons because they have few valence electrons and aren't close to having eight valence electrons.
Explanation:
Just did this question, guessed, and somehow got it right. Hope this helps!!!
Answer:
If there is a large difference between the concentration of one fluid and the concentration of the other, then the particles will diffuse faster. In the experiment, the dye particles in the food coloring are very concentrated.
Explanation:
Answer: no I don’t think so
Explanation:
(a) 6.04 rev/s
The speed of the ball is given by:
where
is the angular speed
r is the distance of the ball from the centre of the circle
In situation 1), we have
r = 0.600 m
So the speed of the ball is
In situation 2), we have
r = 0.900 m
So the speed of the ball is
So, the ball has greater speed when rotating at 6.04 rev/s.
(b)
The centripetal acceleration of the ball is given by
where
v is the speed
r is the distance of the ball from the centre of the trajectory
For situation 1),
v = 30.6 m/s
r = 0.600 m
So the centripetal acceleration is
(c)
For situation 2 we have
v = 34.1 m/s
r = 0.900 m
So the centripetal acceleration is
