A student raises a 4kg ball to an unknown height on a building. It is calculated that the ball has a speed of 30m/s when it hits the ground. Calculate the height it fell from using the law of conversion of energy and the potential and kinetic energy questions

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius
