Explanation:
Given that,
2 strings both vibrate at exactly 220 Hz. The frequency of sound wave depends on the tension in the strings.
The tension in one of them is then decreased sightly, then will decrese.
Beat frequency,
So, the new frequency of the string is 217 Hz. Hence, this is the required solution.
Answer:
The final kinetic energy is
Explanation:
From the question we are told that
The electric field is
The charge on the object is
The mass of the object is
The distance moved by the object is
The workdone on the object by the fields is mathematically represented as
Now this workdone is equivalent to the final kinetic energy so
substituting values
