Answer:
Explanation:
Given:
Four more crests pass in a time of 38.4 s and the distance between the crests is 32 m.
We have to determine five terms.
Lets start with one-one basis.
a.
Period = Time taken by a wave to pass though.
⇒ 
⇒ 
⇒ 
b.
Frequency = Reciprocal of time period in Hertz.
⇒ 
⇒
⇒ 
c)
Wavelength = Distance between two consecutive trough and crest.
⇒ 
d.
Speed (v) = Product of frequency and wavelength.
⇒ 
⇒ 
⇒
e)
Amplitude = The maximum displacement or half the distance from crest to trough.
⇒ Here it can't be determined.
⇒ Impossible.
Answer:
Electric and magnetic fields:
Maxwell's equations tell us that
a changing magnetic field creates a changing electric field and
a changing electric field creates a changing magnetic field

Answer:
(1)
(2)
but 
transition not allowed.
Explanation:
Atoms can be described by the quantum number n, spin quantum number S, angular momentum quantum number L, and total angular momentum quantum number J. Based on approximation Russel- Saunders electron coupling, the atomic term symbol can be written as 
.
The conditions or selection rule to promoting the electron are discussed below:
(1) The total spin should not change that is .
(2) The total angular momentum change should be, but transition not allowed.
Answer:
As the car travels up the coaster it is gaining potential energy.
Explanation:
Because It has the greatest in amount of potential energy at the top of the coaster. when the car travels down the roller coaster it obtains speed and kinetic energy.
