Determine if each of the following statements is True or False about sigma (σ) bonds and pi (π) bonds.

1) A single bond could be either a sigma (σ) bond or a pi (π) bond.

2) A sigma (σ) bond could be formed when an s orbtial and a p orbital overlap end-to-end.

3) Sigma (σ) bonds can be formed by the overlap of an orbital and a hybrid orbital.

4) The picture below represents the formation of a pi (π) bond.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

An electric power distributor charges residential customers $0.10 per kilowatt-hour (kwh). the company advertises that "green power" is available in 150 kwh blocks for an additional $4 per month. (green power is generated from solar, wind power, and methane sources.) if a certain customer uses an average of 391 kwh per month and commits to one monthly 150 kwh block of green power, what is her annual power bill
