Pure gold and silver have densities of 19,300 kg/m^3 and 10,500 kg/m^3, respectively. If a jeweler uses 0.25 cm^3 of metal to make a ring, then how much heavier (in grams) is the gold ring compared to the silver ring? Please do not just steal the points from this question. If you need points that badly just go through your stream and steal them from the older unanswered questions.

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
