Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a string & are in static equilibrium. the 30 kg red sphere has more charge than the 8 kg green sphere. the total charge magnitude on the spheres is 1171 μc & they have the same polarity. as a result the tension is 5062.5 n & the centers of the spheres are 0.78 m apart. determine the charge magnitude on each sphere.

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario
