73 Newton is the correct answer
Answer:
B. 17m/s
Explanation:
This question contains a graph that illustrates the relationship between the speed of a car over time. The graph shows that one can make an inference of the amount of time it takes for the car to cover a particular speed and vice versa.
In this case, after 3 seconds, the speed of the car will be 17 m/s. This inference was got by tracing the position of 3s in the x-axis to the value on the y-axis. Doing this, the best inference for the speed of the car after 3 seconds is 17m/s.
Answer:
The medium for the sound waves produced by the dog barking is the air
Explanation:
Sound waves are a form of mechanical waves such that it moves from one point to another by the vibration, back and forth of the medium particles from one layer to the next, thereby the particles of the medium remain in the same location and only the wave energy is propagated
The medium which has particles that vibrate back and forth in order to transmit the barking of the dog is the air.
Where the displacement is a maximum the pressure is a minimum.
Where the displacement is zero, the pressure is a maximum.
3.0 A i got it off Quizlet and there usually always right lol can't submit tho my answers to short.... Dot dot dot
