What is the average speed of a soccer ball that travels 34m in 2s?

Answers

Answer:

The Average speed will be 17 m/s.

Explanation:

Distance Covered = s = 34 m

Time in which distance covered = t = 2 s

We know that,

Average speed = v = Distance Covered/time taken = s/t  

v = 34/2

v = 17 m/s

Hence, the average speed of soccer ball will be 17 m/s

34/2 = 17 m/s

average speed = distance traveled / time taken

Answers

We have given
original price =150.00
discount=10%=0.1
sales tax=6%=.06
now 
discount=150*0.1=15cost of bike after discount =150-15=135
sales tax=135*.06=8.1
final price =cost of bike after discount +sales tax
final price=135+8.1

Answers

The answer is Near Earth Objects (NEOs).

Near Earth Objects (NEOs) have gained particular interest to scientists in their observations because of its potential threats to the Earth. It can be comets or asteroids. It is called Near Earth since their orbits are too close to cross the orbit of the Earth thus NEO can reach the space near-Earth that more likely give potential threats to the Earth.

Great Lake Effects The Great Lakes influence the weather and climate of nearby land regions at all times of the year. Much of this lake effect is determined by the relative temperatures of surface lake water compared to the surface air temperatures over those land areas. The graph below shows the average monthly temperature of the surface water of Lake Erie and the surface air temperature at Buffalo, New York. In an average year, four lake-effect seasons are experienced. When surface lake temperatures are colder than surface air temperatures, a stable season occurs. The cooler lake waters suppress cloud development and reduce the strength of rainstorms. As a result, late spring and early summer in the Buffalo region tends to be very sunny. A season of lake-effect rains follows. August is usually a time of heavy nighttime rains, and much of the rainy season is marked by heavy, localized rainstorms downwind from the lake. Gradually, during late October, lake-effect rains are replaced by snows. Generally, the longer the time the wind travels over the lake, the heavier the lake effect becomes in Buffalo. Finally, conditions stabilize again, as the relatively shallow Lake Erie freezes over, usually near the end of January. Very few lake-effect storms occur during this time period. The passage states, “The cooler lake waters suppress cloud development…” because the water cools the air above its surface. Explain why this cool air above the lake surface reduces the amount of cloud development.
