In a surface wave (like water) the water goes up and down, but the wave travels across (parallel to) the surface.
Answer:
Explanation:
1) emf stands for elactro-motive force and represents the ability to move electrical charge carriers. Commonly referred to as Volts.
2) P = VI = 1.5(0.31) = 0.465 ≈ <u>0.47 W</u>
3) P = 0.465 - I²R = 0.465 - 0.31²(0.65) = 0.402535 W = J/s ≈ <u>0.40 J</u>
4) 14000 J / 0.40 J/s = <u>35 000 s </u> or about 9.75 hrs
Explanation:
We have,
Speed of plane a is 900 km/h
Plane b is moving at a rate of
It is required to find which plane is faster. To find which plane is faster, we need to compare their speeds.
Speed of a plane a is 900 km/h and that of plane b is 50 km/h. So, we can say that plane a is moving faster.
C because that isn't measurable that is can't be quantified
