The acceleration of gravity is 9.8 m/s². That means that when something
is falling here on Earth, its speed increases by 9.8 m/s every second that
it falls. In other words, whenever you look at it, it's falling 9.8 m/s faster
than it was falling one second earlier.
If you drop an object from some high place ... high enough that it can
keep falling for 6 seconds and not hit the ground yet ... it falls 9.8 m/s
faster every second, and at the end of 6 seconds, it's falling at
(6) x (9/8 m/s) = 58.8 meters per second.
At the beginning of the 6 seconds, its speed was zero.
At the end of the 6 seconds, its speed is 58.8 meters per second.
Its AVERAGE speed over the period of 6 seconds is
(1/2) (0 + 58.8 m/s)
= 29.4 meters per second .
Distance = (average speed) x (time)
= (29.4 m/s) x (6 sec)
= 176.4 meters .
BTW ... Jordan may be in trouble. I'm pretty sure it's illegal
in New York City to drop anything off of a tall building.
If someone happens to be walking by the building at that
particular moment, or 6 seconds later, getting hit in the head
by a penny falling at 58.8 m/s (about 132 mph !) can really
smart, and can muss your do for the rest of the day.
Avocado and cottage cheese are both proteins.
Answer:
3: High and low tides
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Additionally, they are caused by the cycle of rising and falling ocean water that are repeated approximately every 12.5 hours.
In conclusion, the gravitational pull of the Moon is responsible for visible changes on the surface of Earth. Thus, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
It can't be destroyed or created, and in a closed system the energy is conserved.
I hope this helped!

Answer:
created, destroyed, transforms
Explanation:
Energy cannot be created nor destroyed.
Energy is transformed from one form to another form.
- This is the postulate of the law of conservation of energy.
Energy is neither created nor destroyed simply implies that energy is not produce in any system. Nor is it destroyed.
What we have is energy transformation from one form to another.
