Answer:
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
Answer:
The total current supplied by the source of voltage = 10.29 A
Explanation:
We have a 14-Ω coffee maker and a 14-Ω frying pan are connected in series.
Effective resistance = 14 + 14 = 28Ω
Now we have 28Ω and 20Ω in parallel
Effective resistance

So we have resistor with 11.67Ω in a 120 V source of voltage.
We have equation V = IR
Substituting
120 = I x 11.67
I = 10.29 A
The total current supplied by the source of voltage = 10.29 A
Given
The projectile is in air for a time of t=8 sec
To find
The time it takes to reach the highest point
Explanation
A projectile moves up to the highest point and then again moves down following a parabolic path.
So it will reach the highest point at a time half the time it requires to follow teh parabolic path.
The time taken to reach the highest point is 4 sec
Conclusion
The time taken is 4 sec.
