1. Sedimentary rock
2. Metamorphic rock
4. Igneous rock
Umm I’m not 100% sure because I learned all this back in 5th grade and I can’t really remember. But this is what I think I know.
Also for your 2nd question I don’t really know

A microphone is attaced to a spring that is suspended from

kirill115 [55]

To solve this problem we will apply the concept related to the amplitude and the Doppler effect. The difference between the maximum and minimum frequency detected by the microphone would be given by the mathematical function

$f_{max} - f_{min} = 2 f_s (\frac{v_0}{v})$

Here,

$f_s$ = Source Frequency

$v_0$ = Speed of microphone

v = Speed sound

$f_{max} - f_{min} = 2 f_s (\frac{v_0}{v})$

Maximum speed of the microphone is

$v_0 = f_{max} - f_{min} * \frac{v}{2f_s}$

$v_0= \frac{2.1Hz*343m/s}{2*440Hz}$

$v_0= 0.8185 m/s$

Now the amplitude is

$A = \frac{v_0}{2\pi/T}$

Here T means the Period, then

$A= \frac{0.8185 * 2.0}{2\pi}$

A= 0.2605m

Therefore the amplitude of the simple harmonic motion is 0.2605m

Which law of motion accounts for the following statement? "A ball hit by a man travels faster than one hit by a boy."

kifflom [539]

A ball hit by a man is stronger than a ball hit by a man because the man uses more force when hitting the ball than the boy does.
