60 Miles per hour 60 times 2 is 120
Answer:
1.31498 kg
0.72050 s
0.72050 s
Explanation:
m = Mass of block
g = Acceleration due to gravity = 9.81 m/s²
k = Spring constant = 100 N/M
x = Displacement = 0.129 m
The force balance is
The mass of the block is 1.31498 kg
Time period is given by
The period of oscillations is 0.72050 s
The time period does not depend on the acceleration due to gravity. It varies with the mass and the spring constant.
Hence, the time period would be the same
Acceleration is in the direction of motion
Heat transfer is limited to conduction and radiation only in anomalous expansion of water simply because of the temperature at which the expansion occurs and density
<h3>What is anomalous expansion of water?</h3>
Anomalous expansion of water is a property of water in which water expands instead of contracting.
- Anomalous expansion of water makes water less dense.
- The major effect of this anomalous expansion it will still remain less dense and at the surface of water.
- Interestingly, this expansion occurs when it is cooled from 4°C to 0°C.

<h2>
So, the correct answers are:</h2>
Travels in longitudinal waves
Travels most slowly through a gas
Speeds up when temperature is increased
Is caused by vibration
Explanation for correct answers:
Yes, it does travel in longitudinal waves
Yes, sounds weird, but travels faster in the water
Yes, does speed up when temperature is increased
And yes, Is caused by vibration.
<h2>
Wrong answer is:</h2>
Can travel through a vacuum
Explanation for wrong answer:
actually, in space, there is NO sound, because there are no particals for the sound to vibrate with, there's just empty SPACE.
