Answer:
d = 375 m
Explanation:
The speed of sound is constant in any medium, therefore we can use the uniform motion relationships
v = x / t
x = v t
In this case it indicates that the time since the sound is emitted and received is t = 0.50 s, in this time the sound traveled a round trip distance
x = 2d
2d = v t
d = v t/2
let's calculate
d = 1500 0.5 / 2
d = 375 m
No, gravity does not have mass, it behaves like a particle without mass
Answer:B
Explanation:
I’m doing the same thing you are!
<span>the one that should be taken as consideration when describing the quality of a sound is: D.The number of the overtones in the sound
Too many overtones indicated that there is too many unrelated sound that make a lot of the sound's part became redundant and unecessary</span>
Answer:
m=30.581kg
<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>
Explanation:
Assuming this is happening on earth, acceleration due to gravity (g) is 9.81m/s/s.
Force of gravity is the acceleration due to gravity multiplied by its mass:
F=mg
300=(9.81)m
m=30.581kg
<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>
