    Power = Work/ time......(1) Work = Force*distance.....(2) (1) => power = Force*speed power= (1000+10000) *.5 = 5.5 kW You need to add the 1000 N force required to overcome resistive forces.

    The force that makes the pendulum swing is centripetal, therefore any force acting or acceleration produced is directed towards the centre of circle ( in this case, it's imaginary and the pendulum is the radius). Hence, acceleration would be in the direction against gravity and total gravity...

    Reaction 1 is decomposition and decomposition reactions are always endothermic. That heating upto 1000 degrees Celcius was an absolute hint too. Reaction 2 involves braking of a lattice and formation of Ca-OH bonds. If you use a data booklet, you will see that enthalpy of -OH ion is less than...

    I just reviewed my notes and you're right. I drew the first one correct. The second compound is an aldehyde and aldehydes, under harsh conditions can be oxidised into Carboxilic Acids, so if Y is (CH3)3CCH2CH2OH, (C6H14O) Z would be (CH3)3CCH2COOH (C6H12O2).Same reason goes for the third compound.
