Calculate the value of δe in joules for a system that loses 115 j of heat and has 150 j of work performed on it by the surroundings.

Modify the equation fδt=δ (mv) to find the force of friction.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.

At what time would the velocity reach 60.00 km/hr? it will never travel at 60.00 km/hr. it travels at a different constant rate. 10.00 seconds 100.00 seconds
