He started by pushing an empty grocery cart with 0 kg of mass. As the shopping trip progressed, the cart increased in mass from 0 kg to 10 kg. Which argument below supports Raymond's claim that it was more difficult to push the 10 kg cart as opposed to the empty cart. O As the cart decreased in mass, Raymond had to use more force to push the cart. O As the cart increased in mass, Raymond had to use more force to push the cart. O As Raymond continued to push the cart during the duration of the trip, he became tired which made it more difficult to push the cart. O As Raymond continued to push the cart during the duration of the trip, friction began to build up on the wheels causing the cart to be more difficult to push.ALEKS - Alec Nema - Knowledge x G converta^4 to cm^4- Google S x AFreezing Point Depression and Bc X iCPa7ZMmym9SLFOBedXazQM4lzqmR-1UH_pgXn9vQgZypE -→ C合 www-awu.aleks.com/alekscgi/x/Isl.exe/1o_u-lgNs convert m^4 to cm^4- Google Search 出 Apps Sprouts Academy. 6 Online Tutoring C 400 Request Head google.com Question 20 Knowledge Check A NASA spacecraft measures the rate R of at which atmospheric pressure on Mars decreases with altitude.
