A 50.0 kg gorilla is sitting on the limb of a tree 4.00 meters above the ground. The gorilla jumps (falls) down from the tree limb to the ground. Use the conservation of energy to find the velocity of the gorilla just before hitting the ground.

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.

The ph is the a.independent variable b.the dependent variable c.control group

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
