The photon can be absorbed and the energy of the photon is exactly equal to the energy-level difference between the ground state and the level d.
Answer:
Magnitude of the acceleration due to gravity on the planet = 2.34 m/s²
Explanation:
Time period of simple pendulum is given by
, l is the length of pendulum, g is acceleration due to gravity value.
We can solve acceleration due to gravity as
Here
Length of pendulum = 1.20 m
Pendulum executes simple harmonic motion and makes 100 complete oscillations in 450 s.
Period,
Substituting
Magnitude of the acceleration due to gravity on the planet = 2.34 m/s²
B.because electromagnetic waves transmit energy without compressing the particles of the medium
3, 1 could be.
And there's always Heisenberg's uncertainty principle !!!
