A student studied the relationship between the current,voltage,and resistance in a direct circuit.To obtain the results presented in Figure 1 and Table 1,the student constructed the circuit shown below.The student used 3 resistors and different amounts of voltage generate Table 1.The current was read from the ammeter.To obtain the results in Table 1,a 5-ohm resistor (Resistor 4)was used varid .The current was measured at the power was then calculated. If a trial had been performed using Resistor 3 and 12 V, the current would have been:

They were divided randomly into 6 heats, with the fastest 16 qualifying for the semi-finals.These are the results of the 6 heats.From which heat was there only one qualifier for the semi-finals?

A ballet dancer of mass 80 kg and a wingspan of 1m is executing a spin. She then folds her arms and brings them to within 20cm from the central axis of her body. If she was initially making 3 rotations per second, how many does she make now?
