Answer:Twice
Explanation:
It is given that car is raised on a lift with respect to ground.
Suppose car is raised by a height of h m from ground having mass m so gain in Potential Energy by car is
Gain in 
Now if it were raised twice as high,i.e. 2 h height from ground then gain in Gravitational Potential Energy
It is clear that 
Thus in second case gain in Potential Energy is twice as compared to first case
The prefix of a unit could give you a hint on its extent with respect to the base unit. In this case, the base unit is money in terms of dollars. When you say kilodollars, that would be 1,000 times as large as a dollar. Hence,
33,200 dollars * 1 kilodollar/ 1,000 dollars = 33.2 kilodollars
When you say megadollars, that would be a million times as large as a dollar. Hence,
33,200 dollars * 1 megadollar/1,000,000 dollars = 0.0332 megadollars
The other two bulbs stay lit with the same brightness.
The amount of friction depends on the force pushing the surfaces together. If this force increases, the hills and valleys of the surfaces can come into closer contact. The close contact increases the friction between the surfaces.
