With Battery Voltage at 6 volts Run 4 20. Click on the last series parallel circuit (last one on right) 21. Change resistor 1, resistor 2, resistor 3 and resistor 4 to the values in run 4 and record voltage, total current and total power for Run 2 in rows 60-83 16. Calculate the resistance using Voltage and current, again using voltage and power, again using current and power, and again using R1, R2,R3, and R4 recording the calculations for Run 4 rows 2 60-83

Why does the input force have to be greater than the force needed to lift the bale?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?

Astone weighing 1.5 kilograms is resting on a rock at a height of 20 meters above the ground. the stone rolls down 10 meters and comes to rest on a patch of moss. the gravitational potential energy of the stone on the moss is joules.
