Option D is correct. P wave can travel through liquids. P stand for the primary of pressure wave.
<h3>What is wave?</h3>
A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify it. Transverse and longitudinal are the two main forms.
P waves are sometimes known as primary waves or pressure waves. The earliest waves of an earthquake are known as P waves.
P waves may pass through any medium, including liquids, gases, and solids. P waves can't move particles up and down or side to side.
P wave can travel through liquids. P stand for the primary of pressure wave.
Hence, option D is correct

Answer:
Explanation:
You can see that on the x-axis Vx is equal to Vcos and the velocity on the x-axis is all the same.
On the y-axis, Vy is equal to Vsin
Vy : B ( Vsin ) = F ( - Vsin ) > E ( 0 )
Answer:
2763.53411 m/s
Explanation:
M = Mass of Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 m
= Launch velocity
= Final velocity = 500 m/s
h = Altitude = 400 km
m = Mass of satellite
As the energy of the system is conserved we have
The launch speed of the satellite should be 2763.53411 m/s
In physics we refer to how heavy the object is as the mass.
Fg = mass x acceleration due to gravity
Force is directly proportional to mass, thus if force of gravity increases mass also increases.
Answer:
Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop.
