Answer:
F = 268 Hz
Explanation:
The beat frequency is given as:
|
So, for the first flute and tuning fork:
where,
F = Frequency of tuning fork
F = 248 Hz ± 20 Hz
F = 268 Hz (OR) 228 Hz
Now, for the second flute and tuning fork:
where,
F = Frequency of tuning fork
F = 288 Hz ± 20 Hz
F = 268 Hz (OR) 308 Hz
Since, 268 Hz is common from both calculations. Therefore, it will be the frequency of the tuning fork.
<u>F = 268 Hz</u>
Answer:
The distance traveled by car before stopping is
Explanation:
Given
Initial speed of car
Final speed of the car
Acceleration of the car
Let distance traveled before stopping be s
Using equation of motion
=>
=>
Thus the distance traveled by car before stopping is
Answer:
left
Explanation:
N pole should be in the same direction of the field, so N will point left.
Answer:
d = 114.95 m
Explanation:
Givens:
a = 7.6 m/s^2
t = 5.5 s
v_i = 0 m/s
a = (v_f-v_i)/t
7.6 m/s^2 = (v_f-0 m/s)/5.5 s
v_f = (7.6 m/s^2)*(5.5 s)
v_f = 41.8 m/s
d = [(v_f+v_i)/2]*t
d = [(41.8 m/s)/2]*5.5 s
d = 114.95 m
