Answer:
Time period is the time taken by the body to complete one oscillation and it is noted more than once to get accurate reading from averaging of all the observed values.
Answer:
<h2>9.48*10^-5J</h2>
Explanation:
Step one:
given data
mass of ball m=0.43kg
speed v= 75m/h >>>>> to m/s = 75*0.00027
v =0.021m/s
Required
the kinetic energy KE
Step two
applying
KE= 1/2mv^2
KE= 1/2*0.43*(0.021)^2
KE= 0.5*0.43*0.0004.41*10^-4
KE=0.000094815
KE=9.48*10^-5J
The kinetic energy is 9.48*10^-5J
Sound waves enter the ear and cause the eardrum to vibrate. These vibrations pass through connected bones in your ear. This makes fluid move in the inner ear. The impulses of the fluid is converted in the brain to what we "hear".
