Which statement is the NOT an example of the law of conservation of energy? A.
Water falls fromt the sky, converting potential energy to kinetic energy. This energy is then used to rotate the turbine of a generator to produce electricity.

B.
A car burns fuel to move and some of the energy is lost which makes the engine hot.

C.
Energy is transferred from a bowling ball to the bowling pins to make them fall.

D.
Electrical energy is transformed into mechanical energy to move the hands of a clock.

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

What are segments of dna that code for a particular trait. a combination of dna and proteins make up what

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
