All of the planets stay near the ecliptic as they move on the Celestial Sphere
stellarik [79]

Answer:

True

Explanation:

As the Earth goes around the Sun, it will appear that Earth is stationary and Sun is going around it. One can observe the same in real life as well. This apparent path followed by the Sun is called Ecliptic. The plane consisting Ecliptic is called as Ecliptic plane which is same as the orbital plane of Earth.

All the planets of the Solar system are also going around the Sun. Their orbital plane has negligible tilt with respect to Ecliptic plane. Due to this the planets will always appear near to the Ecliptic as they move on the celestial sphere.

mart [117]

Answer:

5.03 m

Explanation:

The wavelength of a wave is given by

\lambda=\frac{v}{f}

where

v is the speed of the wave

f is the frequency of the wave

For the sonar signal in this problem,

f=288 Hz

v=1.45\cdot 10^3 m/s

Substituting into the equation, we find the wavelength:

\lambda=\frac{1.45\cdot 10^3 m/s}{288 Hz}=5.03 m
