To solve this problem we will apply the concepts related to energy conservation. From this conservation we will find the magnitude of the amplitude. Later for the second part, we will need to find the period, from which it will be possible to obtain the speed of the body.
A) Conservation of Energy,
Here,
m = Mass
v = Velocity
k = Spring constant
A = Amplitude
Rearranging to find the Amplitude we have,
Replacing,
(B) For this part we will begin by applying the concept of Period, this in order to find the speed defined in the mass-spring systems.
The Period is defined as
Replacing,
Now the velocity is described as,
We have all the values, then replacing,
The correct answer is option #4. The greatest obstacle to developing solar energy is large areas required to collect sufficient energy. Solar energy is the energy that is the sun is producing and being converted into thermal energy that can be used for everyone's daily lives.
The wind Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
the answer is Jupiter

Answer:
(a): The frequency received by the observers is f'= 138,062.28 Hz.
(b): When the plane flies directly away from them, they receive a frequency of f'= 1772.46 Hz.
Explanation:
Vf= 333.33 m/s
Vo= 0 m/s
V= 342 m/s
f= 3500 Hz
(a) f' = f * ( V / (V - Vf) )
f'= 138062.28 Hz
(b) f'= f* ( V / (V - (- Vf) )
f'= 1772.46 Hz
