An ocean wave is an example of a(n) transverse wave form. Therefore option 1 is correct.
Transverse waves are characterized by the displacement of particles perpendicular to the direction of wave propagation. In other words, the oscillations of the particles occur in a direction that is perpendicular (or transverse) to the direction of wave travel.
When an ocean wave forms, the particles of water move up and down in a vertical motion, while the wave itself moves horizontally. This up-and-down motion of the water particles is perpendicular to the direction in which the wave is traveling, making it a transverse wave.

Answer: Solar Flares
Explanation:
Explanation:
The amount of matter contained inside a body is called its mass while the weight of a body is the gravitational force with which it is attracted towards the earth.
Weight, W = mg
m is the mass and g is acceleration due to gravity
The mass of the object on the moon remains the same but the weight of the body is reduced to one sixth. This is because the moon's gravity is less than the earth's gravity.
Hence, this is the main difference in the weight of the object on the earth and on the moon.
Answer: Three
A plane requires minimum three points for its determination. These three points should be non-collinear or the third point should not lie in same line as made with any two points. By joining two points, a line is formed. A point is one dimensional.
By joining minimum three non-co-linear points, a plane can be formed.
Given three non-collinearpoints in space, they uniquely define a plane. The correct option is C.
Three-dimensional space requires at least three non-collinear points in order to establish a plane. Any additional points would also lie on the plane formed by these three points.
This is due to the fact that a plane is a two-dimensional surface that can go on forever. We define a plane that traverses all three points by joining three non-collinear points.
Their positions when combined result in a flat, continuous surface. More points would simply serve to confirm the plane's definition rather than alter it. Because of this, three points are sufficient to build a plane in three dimensions.
Thus, the correct option is C.

The complex balancing act between a satellite's forward speed and the gravitational force pressing upon it prevents satellites in orbit from falling to the ground or shooting off into space.
When a satellite is put into orbit, it reaches a fast enough speed to escape the Earth's gravitational attraction.
By continuously falling towards the Earth and moving forward at the same time, the satellite may maintain a stableorbit.
This motion results in a curved course, which causes the Earth to be in a constant state of freefall.
Although the satellite is constantly being drawn towards the Earth by gravity, its forward velocity prevents it from dropping.
Thus, satellites don't fall or break free into space and are kept in a stable orbit.
