Answer:
Explanation:
let be the mass attached, let be the spring constant and let be the positive damping constant.
-By Newton's second law:
where is the displacement from equilibrium position. The equation can be transformed into:
shich is the equation of motion.
A. All natural radiation is at a level low enough to be safe
Answer: momentum has the same direction as that of velocity but when 2 bodies with the same linear momentum & different velocities it has different masses because a vector quantity is represented by a cross product of mass and velocity of object .
Answer:
Refer below for the explanation.
Explanation:
Wave energy impacts the earth by utilizing proposed consequences to impact nature by rising normally on to things. The unintended consequences for instance it could vessels sinking.
1) The frequency of the sound is
while the speed of sound is
So we can use the relationship between wavelength, speed and frequency of a wave to find the wavelength corresponding to this sound:
2) The wavelength in this case is
while the frequency of the wave is
So we can use the same relationship we used in part 1) to find the speed of the sound wave:
3) The velocity of the wave is
while its wavelength is
therefore we can find its frequency by using the usual relationship:
