Answer: A crest in a transverse wave corresponds to a Compression in a longitudinal wave.
Explanation:
A transverse wave has crests and troughs. Crest and trough are the points on the wave to which maximum displacement of medium particles in upward and downward direction occurs respectively. The medium particles vibrate perpendicular to the direction of propagation of wave.
A longitudinal wave has compression and rarefaction. The medium particles vibrate parallel to the direction of propagation of wave. A compression is high density region and rarefaction is a low density region.
A crest is the point on the transverse wave to which the medium particle rises maximum. Correspondingly, in a longitudinal wave, the medium particles come closer to each other and form a denser region. This is known as compression.
Statement three i do believe
This is a sneaky trick question, to help you discover whether you know
one of the differences between velocity and speed.
=======================================
If you make a list of the distances and directions, and ignore the times,
you find these:
4 - west, (3 + 1) - east . . . . . zero in the east/west direction
1.5 - north, 1.5 - south . . . . . zero in the north/south direction
This jogger went out, had a nice jog around the neighborhood,and ended up exactly where he started.
Average velocity = (distance between start point and end point) / (time)
IF the question asked for average SPEED, then you would need the total distance, and divide it by the total time. But it asks for VELOCITY, and <u>that</u> only involves the straight distance between the start point and the end point, regardless of the route taken in between.
The jogger ended up exactly where he started. The distance between start and end points was zero. Average velocity is (zero) / (time) . And that fraction is going to be <em><u>Zero</u></em>, no matter how long or how short the trip was, and no matter how much time it took.
A book can have energy by its words by how it’s talking in the book. honestly I’m not too sure that’s just how I would explain it
Answer:
The angular momentum of the solid sphere is 0.667 kgm²/s
Explanation:
Given;
radius of the solid sphere, r = 0.15 m
mass of the sphere, m = 13 kg
angular speed of the sphere, ω = 5.70 rad/s
The angular momentum of the solid sphere is given;
L = Iω
Where;
I is the moment of inertia of the solid sphere
ω is the angular speed of the solid sphere
The moment of inertia of solid sphere is given by;
I = ²/₅mr²
I = ²/₅ x (13 x 0.15²)
I = 0.117 kg.m²
The angular momentum of the solid sphere is calculated as;
L = Iω
L = 0.117 x 5.7
L = 0.667 kgm²/s
Therefore, the angular momentum of the solid sphere is 0.667 kgm²/s
