<span>The diameter of the Moon is 3,474 km. Now, let's compare this to the Earth. The diameter of the Earth is 12,742 km. This means that the Moon is approximately 27% the size of the Earth.</span>
Answer:
The possible range of wavelengths in air produced by the instrument is 7.62 m and 0.914 m respectively.
Explanation:
Given that,
The notes produced by a tuba range in frequency from approximately 45 Hz to 375 Hz.
The speed of sound in air is 343 m/s.
To find,
The wavelength range for the corresponding frequency.
Solution,
The speed of sound is given by the following relation as :

Wavelength for f = 45 Hz is,


Wavelength for f = 375 Hz is,


So, the possible range of wavelengths in air produced by the instrument is 7.62 m and 0.914 m respectively.
Answer:
3 m/s
Explanation:
The slope is distance divided by time, also known as 'speed'.
15 meters / 5 seconds = 3 meters per second.
Answer:

Explanation:
Given,
For the first rocket,
- Initial velocity of the first rocket A =

- Acceleration of the first rocket =

For the second rocket,
- Initial velocity of the second rocket B =

- Displacement of both the rockets A and B = s = 0 m
Fro the first rocket,
Let 't' be the time taken by the first rocket A for whole the displacement

Let
be the acceleration of the second rocket B for the same time interval
from the kinematics,


Hence the acceleration of the second rocket B is -33.65\ m/s^2.
