HELPP!! You run 40 m at 5 m/s and then you walk
another 40 m at 2 m/s. Calculate your average
speed

Why is the use of carbon-14 limited

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.

While preforming an experiment involving a reaction between two chemicals the scientist observes that the reaction container has become warm the observation is an example of
