Answer:
2 charges of electron (2C)
Explanation:
I = Q/t
2 = Q/1
Q = 2×1= 2C
Q = 2 charge of electron
-- She went up for 0.4 sec and down for 0.4 sec.
-- The vertical distance traveled in gravity during ' t ' seconds is
D = (1/2) x (g) x (t)²
= (1/2) (9.8 m/s²) (0.4 sec)²
= (4.9 m/s²) x (0.16 s²)
= 0.784 meter ( B )
the electrons shared between the oxygen and hydrogen atoms spend more time around the oxygen atom nucleus than around the hydrogen atom nucleus
Answer:
4.4721m
Explanation:
#Use Pythagorean theorem to find the distance between the two speakers:

There are antinodes 1/4,1/2 and 3/4 of the distance between speakers.
The greatest antinode is 3/4-1/4=1/2
#Distance between consecutive antinodes is:

Hence, the maximum possible wavelength of the sound waves is 4.4721m
Answer:
Nuclear Forces
Explanation:
Because strong nuclear forces work best within shorter distance.
