C. longest wavelength
Explanation:
Photons with the lowest energy have the longest wavelength and the shortest frequency.
The energy of photons is given as:
E = hf =
where f is the frequency of photon
h is the planck's constant
∧ is wavelength
c is the speed of light
The more the frequency, the higher the energy of the photon.
Photons with low energy have long wavelength.

Drag from her armas would slow her down if she was spinning at a fast speed
Im pretty sure its called a tendon. :/
Answer:
The train is moving with a speed of 57.6 m/s.
Explanation:
Given that,
Distance of observer from the road, d = 40 m (due south)
Velocity of the train, v = 60 m/s (due east)
So,
t is time
Net displacement is given by :
Differentiating above equation wrt t as :
Put t = 4 s
So, the train is moving with a speed of 57.6 m/s.
Answer:
A=4
B=3
c=2
D=1
Explanation:
since the person moving in opposite direction so displacement =distance in east/west - distance in west/east
