Answer:
The number of molecules displaced in a vibration makes the amplitude of a sound.
I’m pretty sure the answer is C. Any change of state or movement requires energy
It increases, because the centripetal acceleration is inversely proportional to the radius of the curvature.
Hopr it helps :)
I personally don't (I can't speak for others tho) but I say right twix is better for the memes
Answer:
The velocity of the plane at take off is 160 m/s.
The distance travel by the plane in that time is 3200 meter.
Explanation:
Given:
Acceleration, a = 4 m/s²
Time, t = 40 s
u = 0 i .e initial velocity
To Find:
velocity , v = ?
distance , s =?
Solution:
we have first Kinematic equation
v = u + at
∴ v = 0 + 4×40
∴ v = 160 m/s
Now by Third Kinematic equation

∴ s = 0 + 0.5 × 4× 40²
∴ s = 3200 meter
