Explanation:
It is given that,
Frequency of vibration, f = 215 Hz
Amplitude, A = 0.832 mm
(a) Let T is the period of this motion. It is given by the following relation as :
(b) Speed of sound in air, v = 343 m/s
It can be given by :
Hence, this is the required solution.
Acceleration = (change in velocity) / (time for the change)
Change in velocity = 59.43 m/s East
Time for the change = 0.312 s
Acceleration = 190.5 m/s^2 East
Answer:
Explanation:
Given that,
Charge,
Revolution = 7 rev
magnetic field, B = 45 mT
Time, t = 1.29 ms
We need to find the mass of the ion. Let m be the mass. The formula for the mass in terms of time period is given by :
So, the mass of the ion is equal to .
Answer with Explanation:
We are given that
Spring constant=k=18 N/m
Amplitude,A=6.5 cm=
1m=100 cm
Number of oscillations=N=19
Time=t=18 s
Frequency=Number of oscillations per second=
Frequency=
1kg=1000g
Mass of the ball=410 g
Maximum speed of the ball=)
Maximum speed of the ball=
Hence, the maximum speed of the ball=0.43 m/s
A = (Vf-Vi) / t,
a = (6-0)/3 = 2m/s^2,
F = ma = 2 * 2 = 4N
