A satellite orbits the moon for 3685 s. It has an orbital radius of 2008177 m. then the acceleration of the satellite would be 5.832 m/s²
<h3 /><h3>What is a uniform circular motion?</h3>
It is defined as motion when the object is moving in a circle with a constant speed and its velocity is changing with every moment because of the change of direction but the speed of the object is constant in a uniform circular motion
The acceleration during the uniform circular motion is given by the formula
a = v²/r
where a is the acceleration
v is the velocity of the object
r is the radius of the orbit
As given in the problem a satellite orbits the moon for 3685 s. It has an orbital radius of 2008177 m.
velocity of the satellite
v = 2πr/t
v= (2×3.14×2008177)/3685
v = 3422.34 m/s
acceleration of the satellite
a = v²/r
a = 3422.34²/2008177
a = 5.832 m/s²
Thus, the acceleration of the satellite would be 5.832 m/s²

The difference between the frequencies of the piano key and the tuning fork gives the frequency of the beats.
When the tuning fork is 405 Hz, and no beats are heard, then the piano key is also 405 Hz.
When the piano key is 405 Hz and the tuning fork is 402 Hz, then 405 - 402 = 3 beats are heard.
The piano key is 405 Hz.
Gamma ray and x Ray I’m pretty sure. Because they have the shortest wavelengths but the highest energy wave. Hope this helped :)
Answer:
Yes, the velocity of the object can reverse direction when its acceleration is constant. For example consider that the velocity of any object at any time t is given as: ... At At t = 0 sec, the magnitude of velocity is 2m/s and is moving in the forward direction i.e.v (t) = -2.
When light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.
To find the answer, we have to know about the rules followed by drawing ray-diagram.
<h3>What are the rules obeyed by light rays?</h3>
- If the incident ray is parallel to the principal axis, the refracted ray will pass through the opposite side's focus.
- The refracted ray becomes parallel to the major axis if the incident ray passes through the focus.
- The refracted ray follows the same path if the incident light passes through the center of the curve.
Thus, we can conclude that, when light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.
