if you double the magnitude of a vector, does it follow that the magnitude of the components double? Give example.

The magnitude of the vector clearly doubles if each of its components is doubled.

Explanation:

The reflection of the candle in the concave mirror formed an upside-down virtual image that is smaller than the candle.in other words. the answer is the third option, c

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
