Kinetic energy:
1) A car traveling down the road has less kinetic energy than a semi-truck and traveling at the same speed because the car's mass is much less than the truck's.
2) A river flowing at a certain speed possesses kinetic energy because the water has a certain mass and it also has velocity.
3) An insect flying has a small amount of kinetic energy because its mass and velocity are relatively small.
Potential Energy:
1) The food we eat has chemical potential energy because as our body digests it, it provides us with energy for basic metabolism.
2) A stretched spring in a pinball machine has elastic potential energy and can move the steel ball when released.
3) When a crane swings a wrecking ball up to a certain height, it gains more potential energy and has the ability to crash through buildings.
Due to the Composition, different asteroids reflect different percentages of the light falling on them.
What are Asteroids:
- Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets.
- Asteroids are generally made up of rocky material, metals and their size are large in comparison to comets. Asteroid belt is found between Jupiter and Mars.
Composition of Asteroids:
- Most of the asteroids in the Main Belt are made of rock and stone.
- The remaining asteroids are made up of a mix of these, along with carbon-rich materials. Some of the more distant asteroids tend to contain more ices.
We determine reflectivity of asteroids by comparing the brightness of light in the visible spectrum to the brightness of light in the infrared spectrum. The light shining from asteroids is reflected sunlight.
Hence we can say that,
Due to the Composition, different asteroids reflect different percentages of the light falling on them.

Answer:
time taken = 7.514 seconds
Here given:
using the given formula:
as we grow up we kinda experience some age staging so a teen got a lotta stuff going on they wanna be social active they be working on their popularity. so i guess thats it
Answer:
Explanation:
2.1 km = 2100 m
1.68 km = 1680 m
a ) Time taken by wild beast to travel 1680 m
= 1680 / 19 = 88.42 s
Time taken by wild beast to travel 2100 m
2100 / 19 = 110.52 s
distance travelled by chicken in 88.42 s
= 88.42 x 3.3 = 291.78 s
Its distance from the end point
= 2100 - 291.78 = 1808.22m
b ) Time taken by chicken to travel 2100 m
= 2100 / 3.3 = 636.36 s
Both reach simultaneously so , time of resting by wild beast
= 636.36 - 110.52 = 525.84 s .
