Answer: B. Title 1 is “Transverse Waves,” and Title 2 is “Longitudinal Waves.”
Explanation:
In transverse waves, the particles of the medium oscillate up and down perpendicular to the direction of motion of wave. crests and troughs are formed. Examples of transverse wave: light wave, wave on a string.
An electromagnetic wave is a transverse wave. It can travel in both space as well as medium. It travels with the speed of light in space and slows down in medium.
In longitudinal wave, the particles of the medium oscillate to and fro parallel to the direction of the motion of wave. Example: sound wave
A sound wave is mechanical wave. It requires medium to travel. A sound wave is longitudinal wave. Sound wave travels forward by compression and rarefaction of the medium.
Thus, the title 1 should be transverse wave and title 2 should be longitudinal wave.
Where the question says "the four different positions", it's talking about
the four situations that are shown in the picture right next to the question.
The question can't be answered without seeing the picture.
I think its a. i am not sure though.
It will take 20 seconds for the car to attain a speed of 34 m/s
Explanation:
- Acceleration of an object is given by a = velocity/time.
- Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time.
- Time = velocity/acceleration
= 34/1.7 = 20 s
So it takes 20 seconds to attain a speed of 34 m/s
I got B,when you subtract 3/5 from NEGATIVE 2/3 it creates a negative 19 over a positive 15.
