The government claims that you save gasoline by driving slower. If you are planning a trip across the US, is there really a substantial saving of gasoline if you travel 35 mph instead of 70 mph? Explain your answer to this question. Your explanation should include: (a) a brief statement of each of Newton’s three laws and how each is relevant to this question;
(b) a clear explanation of the most relevant forces for this question;
(c) a clear explanation of how the forces relate to gasoline consumption;
(d) a quantitative estimate of the relative gasoline consumption (for 35 mph vs. 70 mph).

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
