A mechanical wave travels through a median, an electro magnetic wave fan travel without a median because it is caused by the oscicillation of an electric and magnetic wave
<h2>
The gravitational acceleration on planet X is 32.7 m/s²</h2>
Explanation:
The acceleration due to gravity is given by
where G is gravitational constant, M is mass and R is radius.
For earth we have
g = 9.81 m/s²
That is
For planet X we have
Substituting
The gravitational acceleration on planet X is 32.7 m/s²
