A 1.0 KW kettle contains 500g boiling water. Calculate the time Needed to evaporate all the water in the kettle. (specific latent heat of vaporization of water= 2.26 M Jkg-1 ) [3] B. Explain why the actual time needed is a little longer than time calculated in

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
