The speed of a sound wave does not depend on the frequency of the wave, but only on the properties of the medium.
Since we are in the same concert all, the medium of propagation is still the same (the air), so it has not changed; therefore, the speed of the sound wave has not changed, and it is still 344 m/s.
So, the correct answer is "344 m/s".
Answer:
The nail penetrates into the frame by 1.875 inches
Explanation:
For an 8d nail, it has a length of 2.5 inches, a diameter of 0.13 inches and a head diameter of 0.28125 inches. 8d nails in buildings are used in attaching studs to wall plate, rafter to top wall plates. It is also used when you need to drive a nail at an angle into a wood member.
Since the depth of an 8d nail is 2.5 inches and the sheathing is nailed on the wood frame, to get how far the point of the nail penetrate into the frame, we subtract the depth of the oriented strand board sheathing from the depth of an 8d nail.
Therefore, how far the point of the nail penetrate into the frame = 2.5 inches - 5/8 inches = (2.5 - 0.625) inches = 1.875 inches.
The nail penetrates into the frame by 1.875 inches

<span>The flywheel is solid cylindrical disc. Moment of inertial = ½ * mass * radius^2
Mass = 40.0 kg
Radius = ½ * 76.0 cm = 38 cm = 0.38 meter
Moment of inertial = ½ * 41 * 0.36^2
Convert rpm to radians/second
The distance of 1 revolution = 1 circumference = 2 * π * r
The number of radians/s in 1 revolution = 2 * π
1 minute = 60 seconds
1 revolution per minute = 2 * π radians / 60 seconds = π/30 rad/s
Initial angular velocity = 500 * π/30 = 16.667 * π rad/s
170 revolutions = 170 * 2 * π = 340 * π radians
The flywheel’s initial angular velocity = 16.667 * π rad/s. It decelerated at the rate of 1.071 rad/s^2 for 48.89 seconds.
θ = ωi * t + ½ * α * t^2
θ = 16.667 * π * 48.89 + ½ * -1.071 * 48.89^2
2559.9 - 1280
θ = 1280 radians</span>
