Answer:
a. 18.13m/s
b. 0.84m
c. 2.4m
Explanation:
a. to find the speed at which the ball was lunched, we use the horizontal component.Since the point distance from the base of the ball is 24m and it takes 2.20 secs to reach the wall,we can say that
t=distance /speed
Hence the speed at which ball was lunched is 18.13m/s
b. from the equation
the vertical distance at which the ball clears the wall is
y=8.14-7.3=0.84m
c. the time it takes the ball to reach the 6.2m vertically
the horizontal distance covered at this speed is
Answer:
physic is branch of science in which math is its brother and will deal with the equation,law and evidence of natural phenomenon.
Sunspots are spot like structure on the surface of sun, they are created due to geomagnetic flux which inhibits the convection of heat waves thus reducing the temperature of spot with some factor
<span>Different materials expand and contract at different rates based on temperature. Just like if you leave a plastic bottle full of water in a freezer it will burst, but if you leave it partially full no problem.....Ok?Expansion joints do the same for bridges. There is a gap to allow for temperature related expansions and contractions. Sometimes you drive over bridges and roadways where this movement is constricted and you might notice a bumpy ride. Engineers can predict the variation of structural length based on span lengths and leave the necessary gaps.....btw, NICE QUESTION:)</span>
- Demand of natural resources have influenced human settlement plans .
- Clean air,clean water and food are examples of natural resources
How demands became the obstacles ?
- The demands forces the human to go to different places in order to fulfill their requirements .
- So they have to shift their homes to different places .
