A skier going down a mountain has 98,000J of gravitational potential energy, 10,000J of kinetic energy and 2,000J of thermal energy. At the bottom of the mountain, he has 90,000J of kinetic energy. How much thermal energy does he have at the bottom of the mountain? A) 2,000J B) 8,000J C) 20,000J D) 80,000J

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
