Answer:
330 m/s
Explanation:
The sound wave has to travel TO the cliff AND back = 2 * 49.5 = 99 m
magnitude of velocity = distance / time = 99m / .3 s = 330 m/s
The variables which are involved in understanding Kepler's third law of
motion are
<h3 /><h3>What is Kepler's third law of motion?</h3>
Kepler's third law of motion states that the the square of the orbital period of
a planet is proportional to the cube of the semi-major axis of its orbit. He
also inferred that the greater the distance, the slower the orbital velocity.
This thereby makes option D the most appropriate option as it contains the
orbital velocity and distance to sun variables.

Explanation :
Our solar system was formed about 4.6 billion years ago. It is formed when gravity exerted low-density cloud of interstellar gas and dust. The massive cloud of gas and dust is called as Orion Nebula.
In a small area, the overdensity of clouds occurs. This caused the contraction, to begin. Due to this contraction the potential energy gets converted into kinetic energy of individual gas particles.
Hence the correct option is " materials were pulled together by the gravity". This is the one of the evidence used to indicate the beginning of the solar system.
Answer:
The value is 
Explanation:
From the we are told that
The initial speed of the object is 
The greatest height it reached is 
Generally from kinematic equation we have that
At maximum height v = 0 m/s
So
=> 
Here H is the height from the initial height to the maximum height
So the initial height is mathematically represented as
=> 
=> 
Generally the time taken for the object to reach maximum height is mathematically evaluated using kinematic equation as follows
At maximum height v = 0 m/s
=> 
Generally the time taken for the object to move from the maximum height to the ground is mathematically using kinematic equation as follows
Here the initial velocity is 0 m/s given that its the velocity at maximum height
Also g is positive because we are moving in the direction of gravity
So
=> 
Generally the total time taken is mathematically represented as
=> 
=>
Carbon is found in the solid form in geosphere of our earth. Coal and oil are some of the examples of materials containing carbon in the geosphere. when the coal or oil is burnt, carbon dioxide is formed and released in atmosphere. This carbon dioxide is absorbed by the water of the hydrosphere with the help of algae and plankton. The water turns acidic in nature. This way carbon is transferred from geosphere to hydrosphere.
