Explain why there is no acceleration horizontally on an object in projectile motion. a. there is no acceleration horizontally because velocity is constant in the x- direction. b. there is no acceleration horizontally because velocity increases in the x- direction. c. there is no acceleration horizontally because velocity decreases in the x-direction . d. there is no acceleration vertically because velocity is constant in the y -direction .

Iflow from a warmer object to a cooler object until both objects are the same temperature what am i?

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
