Two cars both weighing 1,000lbs are driving down the highway. car #1 is traveling 60mph while car #2 is traveling 70mph. how does the kinetic energy between the two compare

The answer would be:

Car 2 has a greater kinetic energy than Car 1.

Here's why:

Kinetic energy is directly proportional to the mass and square of the velocity of an object. The formula is:

Where:

KE = Kinetic energy

m = mass

v = velocity

Because Car 2 is faster than Car 1, then it would mean that it has a greater kinetic energy than Car 1. What about the mass? The mass of the two cars are the same, so the difference would not be affected by it.  

they may bind directly to special “promoter” regions of dna, which lie upstream of the coding region in a gene, or directly to the rna polymerase molecule.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.
