58775.51 J kinetic energy is lost,
Energy lost = 0.5*mv²
= 0.5*8000/9.8 * 12*12
= 58775.51 J
To calculate the energy loss of a moving object, subtract the initial kinetic energy from the final kinetic energy, where the initial and final kinetic energies are calculated using the formula 1/2*M*V^2.
When energy is transformed from one form to another or moved from one area to any other, or from one device to another there's energy loss. This means whilst energy is converted to a different form, some of the entering energy is become an especially disordered form of energy, like heat.

Explanation:
hope you understood fella
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.
Answer:
differences and similarities
Explanation:
An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound. whereas,
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
Answer:
the reason why u may experience shock is because. of friction. if you were to hold onto the body of the car there would be no shock because friction isnt present you are most likely to notice this on a warm day because friction mostly happens in those types of environments. heat rubbing together equals friction.
