The potential energy he lost on the descent = M g H = (21.2) (9.8) (3.5) = 727.16 joules
The kinetic energy he had at the bottom = 1/2 M V2 = (0.5) (21.2) (2.1)2 = 46.746 joules
The missing energy = (727.16 - 46.746) = 680.414 joules caused heating of the slide and the kid's pants.
Use conservation of energy to solve this one. Calculate the gravitational potential energy at the top, and the kinetic energy at the bottom. The difference has been lost to friction, i.e., converted to thermal energy.
The answer depends on the coefficient of friction between the child's clothing and the slide as well as the speed with which the child reaches the bottom of the slide.
When a ribsome reaches a stop codon, the translation process stops and a protein is released.

Some sort of precipitation occurs when air reaches the dew point. You might get dew, frost, rain or snow.
Magma reaches the earth surface during an eruption. Once the magma is on the surface it is called lava.
Hormones are released by the endocrine system.
The answer depends on the incline (slope) of the slide. And, if you want a more realistic answer, a measure of the friction between the child and the slide.
When a ribsome reaches a stop codon, the translation process stops and a protein is released.
Friction generated as the meteoroid enters the atmosphere generates enough heat to vapourise the rock before it reaches the Earth's surface.
friction is a natural phenomenon it is always being used.. always, every second of everyday there is friction in action everywhere even in the deep reaches of space. I mean literally EVERYWHERE and ALWAYS.
Yes
The solid-state welding processes. This can include friction and friction stir welding where the base metal never reaches its melting point.
Gravity x length of slide ,+ unknown factors of slide material
When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.
it is used in metabolic process
wat can it be
When it reaches its boiling point.
yes,you can see friction. think of when a plane is about to break the speed of sound, ok now as the plane reaches speeds of over 700 mph you start to see a white circle around it, that is the air rubbing against the plane so yes you can see friction
