The transportation sector is the highest contributing factor to greenhouse gas emissions in the world. Vehicles such as cars, motorcycles, airplanes, ships etc all emit these gases which causes global warming.
Electric cars is known not to little or zero direct emission and known to be safer. It however emits nitrogen oxide which is fog like in a very minute quantity.
Answer:
Explanation:
A smaller clearance volume means a higher compression. A higher compression means better thermal efficiency. However a compression ratio too high might be troublesome, as it can cause accidental ignition of the fuel-air mix. This is the reason why Otto cycle engines have lower compressions that Diesel engines. In a Diesel engine the mix ignites by compression instead of a spark.
Answer:
The question is incomplete, the complete question is:
Which of the following is not a reason to give yourself extra "cushion" when driving?
A. Poor visibility B. Poor road conditions C. Inclement weather D. None of these.
The correct answer is D. None of these.
Explanation:
All the options are not reasons to give yourself an extra cushion when driving, rather they are reasons that are not favorable to driving at all.
A cushion is a certain amount of distance you are supposed to keep between you and the car in front of you to allow easy maneuvering in any condition.
A typical cushion is 3 seconds between you and the car in front of you, in less than perfect conditions like bad weather or poor road conditions an additional second must be added to it.
Answer:
depends on the size
Explanation:
Length x width x depth x 7.5 = volume (in gallons)
Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool, expressed in gallons.
