15 Define the volt, the watt and the kilowatt-hou
An electric lamp is marked '100 W, 220 V
What do you understand by this? What current
is taken by the lamp when it is connected to
220 V mains supply? What is the resistance o
the lamp?

Apackage of supplies is dropped from a plane, and one second later a second package is dropped. neglecting air resistance, the relative velocity of the 1st package viewed from the second will 56) a) increase. b) be constant. c) be zero. d) depend upon their weight. e) decrease

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.

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
