Answer:
(A) v = 14.8m/s
Explanation:
(A) V = sqrt(k/m) × A = sqrt(22/0.1) × 0.29 =14.8m/s.
Answer:
C. Weight is mass times the acceleration of gravity.
Explanation:
Weight is the force exerted by gravity. Force is equal to mass times acceleration.
Answer with Explanation:
We are given that
Fundamental frequency,f=88.4 Hz
Speed of sound,v=343 m/s
We have to find the first three overtones.
Tube is closed
The overtone of closed pipe is equal to odd number of fundamental frequency.
Therefore, the overtone of tuba
Where n=3,5,7,..
Substitute n=3
For second overtone
For third overtone
Answer:
here given is a weight
then force becomes mg
that is F=Mg
=4*9.8
then by using the formula
F=Ma
a=F/M
=4*9.8/9.8
=4
