Generator

A generator is a device changes mechanical energy to electrical energy by rotating a coil of wire through a magnetic field

Explanation:

In an electric generator the permanent magnet is span by a small piston engine powered by fuel. Which is why we put petrol/diesel in an electric generator. The crankshaft of the engine spins a permanent magnet surrounded by a coil of wires with many wounds. An electric current is induced in the coil of wire by dynamo effect - the more the wounds of the coil, the bigger the induced current This also observes the Fleming's rule of the thumb (right hand in this case) on electric induction. An electric generator works in reverse of an electric motor.

While walking along the shore of a lake Travis felt a cold breeze. What type of heat energy transfer is this an example of?

AfilCa [17]

Out of the 3 types of heat transfer, this scenario would be most likely to be an example of convection.

Convection is where the transferring of heat is resulted through the movements of fluid, but in this case it is air. What happens is that when a part of the whole mass of air is heated, the hotter air rises and the cooler air descends and takes place of the hotter air before it was heated. Then, the cooler air becomes hotter and the hotter air before becomes the cooler air of both, which then results to the repeat of the exchange of places. This creates a motion until the whole mass has achieved mutual temperature, the heat source has stopped or extinguished, or there is a shift of temperature.

A motorcycle is speeding along at a velocity of120kph.Then, it changes to a velocity of 150 kph for 2 minutes.What is the motorc

Taya2010 [7]

Answer:

Explanation:

a=v-u/t

a=acceleration

v=final velocity

u=initial velocity

t=tme taken

we need to convert from kph to ms⁻¹

v= 150*1000/60*60= 41.67ms⁻¹

u= 120*1000/60*60= 33.33ms⁻¹

t= 2*60= 120s

a=41.67-33.33/120

a=8.34/120

a=0.0694ms⁻²

Viefleur [7K]

Answer:

Explanation:

The equilibrium mechanism for the reversible acid is catalyzed by the isomerization of non conjugated Î², Î³- unsaturated ketones, like 3-cyclohexanone to their conjugated Î±, I²- unsaturated isomers.

Oxygen of the Carbonyl group in the ketone is protonated by the acid and this is followed by the abstraction of an Î±- hydrogen from the protonated 3-cyclo hexanone to yield ethanol

2-cyclo hexanone can be obtained by acid catalyzation of 3-cyclohexanone isomers through the formation of it's "enol".
