Answer:
Mass of 17.854 kg is only attached to the spring
Explanation:
We have given time period in first case is 22 sec
Let initially mass is m
After 22 kg are added the period becomes 33 sec
Time period of spring mass system is
, here m is mass and k is spring constant
From the relation we can see that
Squaring both side
m = 17.584 kg
So mass of 17.854 kg is only attached to the spring
Answer:
is B because 35 times 2.9 equals 101.5 and if you round it is 102
what ever force the wave hit it at (on the x-axis) would create another wave from the force of the first wave. though the wave would be smaller because of other forces
Answer:
3,333.33 /sec
Explanation:
frequency = 1/period
= 1/0.0003 = 3,333.33 /sec
Answer:This Answer is B
Explanation:
Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
