Gina stands 1.5 m in front of a plane mirror. She is 160 cm tall (i. e. HF = 160 cm) and her
eyes (E) are 10.0 cm below the top of her head (H).
What is the shortest length of the vertical mirror that will enable her to see her entire
image? Draw a ray diagram below with necessary calculation below to support your answer.
Please help!

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

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.

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
