Answer:B
Explanation: An analog audio signal is measured at regular intervals. Each measurement is stored as a sample, which is represented at the lowest level as a sequence of bits.
The correct answer is B. The pickup truck is moving at 4 m/s and the school bus is moving at 2 m/s.
Explanation:
The kinetic energy is related to how fast a body moves (speed), as well as, the amount of matter in the object (mass). Due to this, even if the bus and the truck move at the same speed they do not have the same kinetic energy. Indeed, the graph shows in general the kinetic energy is higher for the school bus.
However, this does not occur if the truck moves at 4 m/s and the bus moves at 2m/s because, at this speed, the kinetic energy of the truck is 30 kilojoules, while the kinetic energy of the bus is around 15 kilojoules, which is lower. According to this, the correct answer is B.
Answer:
The United States has few reserves and a very high consumption rate.
Explanation:
If the United States keeps using fossil fuels, they will run out very quickly and an alternative will be needed, the second answer choice supports that.
Try common ratio, because b represents a constant variable. (I’m not 100% but it may be this)
