Hello there!
Physical changes do not change what a substance is, whereas a chemical change results in a new substance being formed, so they do change what a substance is.
I hope I could help you to solve this question. Have a great rest of your day! :)
I'd say A. because an inference is a guess/estimate. You can assume that the egg rolled off the kitchen but you know that C and D are true.
Answer:
No they are totally different...
Velocity is displacement/time. while vector is both magnitude and direction.....
Velocity is a vector quantity because it has both magnitude and direction
I think the correct answer from the choices listed above is the second option. The relationship between the direction of energy and wave motion in a transverse wave would be the <span>energy direction is perpendicular to the motion of the wave. Hope this answers the question. Have a nice day.</span>
Longitudinal waves transfer energy parallel to the direction of the wave motion
