<span>B. This is because P-waves is shorthand for Pressure-waves. Pressure waves compress and stretch along the direction of motion.</span>
Answer:
0.31 m
Explanation:
m = mass of the block = 1.5 kg
H = height from which the block is released on ramp = 0.81 m
k = spring constant of the spring = 250 N/m
x = maximum compression of the spring
using conservation of energy
Spring potential energy gained by spring = Potential energy lost by block
(0.5) k x² = mgH
(0.5) (250) x² = (1.5) (9.8) (0.81)
x = 0.31 m
Answer:
It would be λ=V/f
Explanation:
λ = wavelength
V = velocity
f = frequency
The equation for a wavelength is velocity over frequency, therefore the answer would be λ=V/f.
Good luck with your physics!
<u>Answer:</u> The given statement is True
<u>Explanation:</u>
A uniform motion is defined as the motion where an object is moving at a constant speed.
A non-uniform motion is defined as the motion where an object keeps changing its position and does not move at a constant speed.
We are given:
A car takes a full round of journey in a roundabout with constant speed
As the speed remains constant in a circular path, it is considered a uniform motion.
Hence, the given statement is True
