Question:

need help with my physics exam (home test)?

2 cars are being lifted up to the same height in a garage, car A weighs 1000 kgs and car B weighs 2000 kgs, write the letter A for car A, letter B for car B or write the letter C if the answer is both.1. It requires more work to lift up car ____2. Car ___ has more potential gravitational energy.3. If both cars fall, car ___ will accelerate more.4. If both cars fall, car___ will fall with more momentum.5. If both cars fall, car ____ will fall with more kinetic energy

Answer:

I think you are supposed to have your transmission fluid flushed at your 90,000 mile mark. Probably again at 150,000. Check your owner's manual.
It is perfevtly safe. When you get your transmission flushed it take all the tranny fluid out of the trannsmison. However when you just get it changed only about 60% of the fluid is replace.
1. It requires more work to lift up car B 2. Car B has more potential gravitational energy. 3. If both cars fall, car C will accelerate more. 4. If both cars fall, car B will fall with more momentum. 5. If both cars fall, car B will fall with more kinetic energy
at normal mileages it is fine . but if you have gone a very long time without a service, you could run into problems. by a long time i mean 75000 -100,000 miles. you can run into problems at lower durations, but that does not happen very often. if you look at the fluid condition prior to theat flush you can kind of guess the results. if the fluid is dark and smells like varnish, (back away)
