Modern automobiles are generally designed so that the engine compartment at the front end of the car collapses during a collision. What is the purpose of this design? A. The collapsing structure increases the transfer of the energy to the car or object with which the car collides.
B. It is less expensive and more cost effective to use weaker materials in the construction of the engine compartment.
C. By confining the damage to the front part of the car, the collapsing engine compartment reduces the total cost of repairs.
D. As the materials of the engine compartment bend they absorb energy and protect the passengers from the force of the collision​

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc

Which is not one of the major climate zones? question 3 options: rain forest polar tropical temperate

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
