Answer:
The frequency of the piano string is <em>1059 Hz</em>.
Explanation:
The frequency beat (fb), 2 beats/second, is the absolute difference between the frequency of the tuning fork (1056 Hz) and the frequency of the piano string.
As the piano string gets tightened, the frequency beat becomes 3 beats/second.
Therefore,
fb =
Answer:
The voltage drop through which the proton moves is 39.1 V.
Explanation:
Given that,
Distance = 4.76 cm
Time
We need to calculate the acceleration
Using equation of motion
Where, s = distance
a = acceleration
t = time
Put the value in the equation
We need to calculate the voltage drop
Using formula of electric field
....(I)
Using newton's second law
....(II)
Put the value of F in equation (I) from equation (II)
Where, q = charge
a = acceleration
d = distance
m= mass of proton
Put the value into the formula
Hence, The voltage drop through which the proton moves is 39.1 V.
