Answer:
Explanation:
It is given that the ball is lodged in a hole in the floor of merry-go-round that is running at a constant speed.
Now the ball is moving a vertical circular motion
The position of the ball changes w.r.t to the center as it moves in a circular path i.e. vectorially it changes but its magnitude will remain the same.
The velocity of the ball is the same as merry-go-round so its magnitude remains the same but its direction will change continuously.
As the ball is moving in a circular path so a centripetal acceleration will acts towards the center so its value will be continuously changing.
It's denoting to a right angle traingle
- Perpendicular=P=3+1.7=4.7m
- Base=B=8.1m
Hypotenuse we need
Apply Pythagorean theorem
- H²=P²+B²
- H²=4.7²+8.1²
- H²=87.7
- H=9.4m
The main difference is the source of the sediment that the rock is formed from. Clastic sedimentary rocks are formed mostly from silicate sediment derived by the breakdown of pre-existing rocks. Bioclastic rocks are formed by the accumulation of fragmented organic remains (such as shell-sand) - i.e. the sediment is of biological rather than non-biological origin.
Answer:
<h2>Gravity :</h2><h3>the force that attracts a body towards the centre of the earth, or towards any other physical body having mass.</h3>
<h2>Solar day</h2><h3>A solar day is the time it takes for the Earth to rotate about its axis so that the Sun appears in the same position in the sky.</h3><h2> or</h2><h3>It is the time between successive meridian transits of the sun at a particular place.</h3>
