A film director is organising a stunt for his latest film. A stuntman will jump over part of the Grand Canyon on a motorbike. The canyon is only 100 m wide at the part where the ramp has been built and the length of the ramp is 12 m. As a safety inspector you have been asked to assess if the jump is possible. Using the diagram of the ramp below you must calculate the minimum speed the motorbike must by doing at the top of the ramp if it is to make it across. (You can ignore air resistance or wind).

ramp is 30 degrees so opp is 6m

How much heat energy is given out when 300ml of 0.1 M NaOH solution is reacted with sufficient HCl solution.

NaOH(aq) + HCl(aq) -> NaCl(aq) + H2O(aq) ?H= -56.2kJ/mol NaOH

And assuming that the volume of the solution after reaction is 600 mL, with mass 600g and the initial temperature of the solution was 25°C, and also assuming that the heat capacity of the solution is the same as water's = 4.184 J/g/K. What is the final temperature of the solution after the reaction?

This is a nasty one. I'd like to see the work.

How many years would it take, how much of the earth needs to actually get involved, how possible do you think it is that we can actually fix it. Or do you feel it is too late.
