What do you mean by kinetic energy ? Derive an expression for the kinetic energy of an object of mass m moving with velocity,υ. View Solution What is the kinetic energy of a body of mass 1 kg moving with a speed of 2 m/s ?
i did what i had to d i didn t respond i didn t stare i didn tmean to offen i didnt get any money i didnt mean to hurt i didnt realize how l i didnt really believ i didnt watch you go i discuss the traditi i do it out of the lo i do too i dobut i decided id i dodg...
How would you explain the difference between kinetic energy and potential energy? Give an example from the real world where potential energy is transferred to kinetic energy. What do you mean by kinetic energy of body? Give some examples. What is kinetic energy and potenti...
The average kinetic energy of localised particles is defined as temperature (i.e., the particles surrounding your thermometer). Your temperature reading would be absolute zero if there were no particle’s surrounding your thermometer (because you are in a perfect vacuum).However, we know from the...
If {eq}He {/eq} gas has an average kinetic energy of {eq}7050\;J/mol {/eq} under certain conditions, what is the root mean square speed of {eq}O_{2} {/eq} gas molecules under the same conditions? ...
We’ll have wind in the world as long as these conditions are met. This means that we can turn as much of it into energy as we want, and there’ll always be more. Are Wind Turbines Efficient? Just because wind turbines generate sustainable energy doesn’t mean that they do so efficien...
your fitness goals will allow you to choose the treadmill that’s best suited for your personal use and can make a big difference in your bank account. Let’s break down the key components of a treadmill motor and, more importantly, what they mean in finding the right treadmill for you....
This is the starting point for the below, Feynman being prescient again, but a masterclass. POINT: We know what to do and have come close to understanding much of nature in the last 200 years. In particular the last 20 years when most of the pseudo science of the Agenda 21 movement ha...
Degradation refers to the reduction of grip caused by a tyre getting too hot. If you hear drivers talk of not getting their tyres 'in the window', they mean they haven't been able to drive the car in such a way that the compound stays in its ideal operating temperature w...
Express the direction as an angle with respect to the positive x-axis. What does this question mean? How do you determine which transformations are not a rigid motion? A 3000 kg car was traveling on a horizontal road. It started from rest and accelerated uniformly 30 meters in...
