Answer:
B
Explanation:
kinetic energy (KE) is the energy possessed by moving bodies. It can be expressed as:
KE = m
Where: m is the mass of the object, and v its speed.
For example, a stone of mass 2kg was thrown and moves with a speed of 3 m/s. Determine the kinetic energy of the stone.
Thus,
KE = x 2 x
= 9
KE = 9.0 Joules
Assume that the speed of the stone was 4 m/s, then its KE would be:
KE = x 2 x
= 16
KE = 16.0 Joules
Therefore, it can be observed that as speed increases, the kinetic energy increases. Thus option B is appropriate.
Answer:
Explanation:
From the question we are told that:
Frequency of 3rd harmonics
Frequency of 5th harmonics
Generally the equation for Wavelength at 3rd Harmonics is mathematically given by
Therefore
Generally the equation for Wavelength at 1st Harmonics is mathematically given by
Therefore
Generally the equation for the frequency of the first harmonic is mathematically given by
