Answer:
a) 1.2*10^-7 m
b) 1.0*10^-7 m
c) 9.7*10^-8 m
d) ultraviolet region
Explanation:
To find the different wavelengths you use the following formula:
RH: Rydberg constant = 1.097 x 10^7 m^−1.
(a) n=2
(b)
(c)
(d) The three lines belong to the ultraviolet region.
Answer:
Charge enter a 0.100 mm length of the axon is 
Explanation:
Electric field E at a point due to a point charge is given by
where 
is the constant =
is the magnitude of point charge and 
is the distance from the point charge
Charges entering one meter of axon is 
Charges entering 0.100 mm of axon is 
substituting the value of 
in above equation, we get charge enter a 0.100 mm length of the axon is
I think the right answer is the first one. If she stops moving her Position does not change any more-and the Graph Shows that after 6 seconds she stays at the Position of 5 m. If she Went Back to the start point the Graph would have Developed Back to 0m(decreased).
Answer:
heat and sound.
Explanation:
Though some would argue that the heat is not useful. I guess it depends on if your hands are cold.
The reading on the scale is the tension on the string that connects the two objecst. In order to support the blocks it must pull the weights by a force magnitude of W. So, the tension of the rope is W. Therefore, the reading on the scale is W, D.
