Explanation:
Downwelling is the process where cold and heavy dense water moves down into the ocean floor and warm light dense water rises to the surface. As a result of downwelling, the water high dense water which rises to the water surface brings the oxygen rich water to the surface for the marine animals to breathe properly. Also when the ocean surface water becomes little warmer it becomes a little comfortable for the marine animals to survive in this severely cold climatic conditions at polar reasons.
Explanation:
Given that,
Each vertical line on the graph is 1 millisecond (0.001 s) of time.
We need to find the period and the frequency of the sound wave. The period of a wave is equal to the each vertical line on graph i.e. 0.001 s.
Let f be the frequency of the sound wave. So,
f = 1/T
i.e.

So, the period and the frequency of the sound waves is 1 milliseond and 1000 Hz respectively.
Answer:
one at the edge
Explanation:
The relation between the linear velocity and the angular velocity is given by
v = r x ω
Where, v be the linear velocity, ω be the angular velocity and r be the radius of the circular path.
As the angular velocity is constant, thus, the linear velocity depends on the radius of circular path.
So, the horse which is near to the edge has maximum radius of circular path in which it is rotating. So, the horse which is at the edge of the merry go round has maximum linear speed.
Answer:
3.605551275463989
Explanation:
solve using Pythagorean theorem
It would take <u> 8 years </u> for the asteroid to orbit once around the sun.
What is a semimajor axis?
- In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter.
- The semi-major axis (major semiaxis) is the longest semidiameter or one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter.
- The semi-major axis of a hyperbola is, depending on the convention, plus or minus one half of the distance between the two branches.
- Thus it is the distance from the center to either vertex of the hyperbola.
- In astronomy, the semi-major axis is one of the most important orbital elements of an orbit, along with its orbital period.
- For Solar System objects, the semi-major axis is related to the period of the orbit by Kepler's third law.
