John runs around a 126.5 m circular track 3.5 times in 4.17 minutes. What is his average speed?
sdas [7]
Average speed = distance traveled / time

average speed  = (126.5 m * 3.5 laps) / (4.17 min)

= 106.2 m/min

if gas in a sealed container has a pressure of 50kpa at 300k what will the pressure be if the tempature rises to 360k
Zarrin [17]
The pressure law states that pressure is directly proportional to temperature.
p=kt where p is pressure, k is a constant, and t is temperature.

p=kt -- substitute
50000=k*300000
k=1/6
p=1/6*360000
p=60000 -- in pa not kpa

The pressure is 60kpa

a DJ uses a 110-volt outlet to plug in a strobe light. if the current flowing through the light is 0.050 amps, how much resistan
tigry1 [53]

Ohms Law: V = IR

V is the voltage in volts

I is the current in amps

R is the resistance in Ohms

Rearrange: R = V/I

R = (110)/(0.050)

R = 2200

There are 2200 Ohms of resistance in the circuit.
