Answer:
Kinetic energy is maximum when the player hits the ball.
Explanation:
Kinetic energy 
, where m is the mass and v is the velocity.
So kinetic energy is proportional to square of velocity.
Velocity is maximum when the player hits the ball.
So kinetic energy is maximum when the player hits the ball.
The correct answer for the given question above would be option B. Air flowing from the equator to the poles rises and falls in looping patterns and these patterns are called convection cells. Convection cells<span> is an important process in the formation of landforms and the movement of winds. Hope this answers your question.</span>
Answer:
<em> It takes 186.67 second for the light to travel from Mars to earth.</em>
Explanation:
Light: Light is a visible form of energy which is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.
S = d/t .......................... Equation 1
making t the subject of the equation
t = d/S ......................... Equation 2
Where S = speed of light, d = distance between the earth and Mars, t = time
<em>Given: d = 56000000 km, S = 300000 km per seconds.</em>
<em>Substituting these values into equation 2</em>
<em>t = 56000000/300000</em>
<em>t = 186.67 seconds.</em>
<em>Thus it takes 186.67 second for the light to travel from Mars to earth.</em>
Tides are incredibly vital. They are controlled by the gravity of the moon pivoting the earth on a 28 day cycle, pulling the water round the world.
On the off chance that you are a mariner you require tide tables for two vital reasons. The first is that the water may not be sufficiently profound to get in and out of harbor or, say, over a sand bank, until specific times of day.
Another reason is that to spare time and power we need to cruise with the active tide on the off chance that it is going our path - to cruise against the tide can mean really going in reverse - I have seen vast cruising vessels beating to windward against the tide on the western ways to deal with the Solent going actually in reverse, (however they had forward speed through the water). Terrible arranging!
Since it is a 28 day cycle and there are 13 heaps of 28 days in a year the tides shift day by day with respect to when it is high tide and low tide, More than that we have neap tides when the highs and lows are less and spring tides when they are most prominent. These rely on upon the periods of the moon.
On the environment front they wash into and through ocean growth circulating air through the plants and ocean life and mix up silt to clean the base of the shoreline and channels and estuaries and invigorate pools that stay on the shoreline for other plant and creature life. This is one justifiable reason motivation behind why tidal hindrances will be a calamity for beach front life since this will be lost to power era. A similar thing applies to wave control and, ashore, wind control - there will be a substantial environmental cost to any maintained or pragmatic utilization of vitality that is in truth not "renewable" - we will upset a fragile adjust of nature that will do much more harm than carbon ever could (on the off chance that it was doing any harm now, which I question)
Tides are not such a great amount of checked as anticipated but rather perilous high tides can happen at the most elevated spring tide, with the twist inland and low gaseous tension - everything pushes the water advance up the shoreline and cause harm and flooding.
