Answer:
Explanation:
As per energy conservation we can say that during path 1. his initial total mechanical energy must be equal to final total mechanical energy
So we will have
so we will have
Now while he is moving on path 2. then again we can use energy conservation to find the speed
The Earth takes (365 and 1/4) days to orbit the sun. That's the length of our 'year'.
Since it's not really possible to make our calendar a quarter of a day longer every year, we make the calendar a <u><em>whole</em></u> day longer every 4 years.
So "Leap years" make up for the extra one-fourth day the Earth takes to orbit the sun.
Answer: The answers are A. Wind, B. Water, and D. Gravity.
Explanation: All four factors contribute to weathering and erosion; however, ice is not shown in the image, so it likely did not play a role in the collapse of the cliff.
(Next time please provide an image so it would be easier!)
Velocity and acceleration are vector quantities whereas speed, temperature and age are not.
<h3>What is a vector quantity?</h3>
Vector is a quantity that has both magnitude and direction and is represented by an arrow whose direction is same as that of the quantity and length is proportional to the quantity's magnitude.
Vector has magnitude and direction but it does not have position. Velocity and acceleration both are vector quantities as they have magnitude and direction.
If the speed of an object remains same but direction changes then the object is accelerating. It is important to remember that acceleration and velocity aren't always in the same direction.

HEY THERE !!
It is called SUBLIMATION.
so the correct answer is (D).
