Try practicing basketball in your free time and learn to love it. You can also apply to schools or teams that teaches basketball more. Get good teachers.
Answer:
23.49m
Explanation:
Distance = velocity x time
8.7 x 2.7 = 23.49m
Answer:
M = 6.32 x 10⁻⁶ H
Explanation:
given,
Length of solenoid = 10 cm = 0.1 m
diameter = 0.40 cm
radius = 0.2 cm = 0.002
number of turns, N₁ = 800
N₂ = 50
mutual inductance will be equal to


M = 6.32 x 10⁻⁶ H
hence, mutual inductance of the combination of two coil is equal to M = 6.32 x 10⁻⁶ H
What it looks to be that you found in A was the "initial"...b/c the question asks:
<span>"how much energy does the electron have 'initially' in the n=4 excited state?" </span>
<span>"final" would be where it 'finally' ends up at, ie. its last stop...as for this question...the 'ground state' as in its lowest energy level. </span>
The answer comes to: <span>−1.36×10^−19 J</span>
You use the same equation for the second part as for part a.
<span>just have to subract the 2 as in the only diff for part 2 is that you use 1squared rather than 4squared & subract "final -initial" & you should get -2.05*10^-18 as your answer. </span>
