Explanation:
Distance is the length of the path traveled. Displacement is the difference between the final position and initial position.
Distance = 224 m + 156 m + 84 m + 248 m = 712 m
Displacement = 224 m − 156 m + 84 m − 248 m = -96 m
Displacement = 96 m westward
That's true because every action has an equal and opposite reaction and weight is literally the force gravity has on an object.
To determine the number of hair dryers that can be plugged in to a circuit, our basis is the maximum threshold of the current. The current which measures 12 Amperes. This current already incorporates the safety factor that is important in industrial setting.
The voltage and the current can be related to the power by the equation:
P = I*V, where I is the current in Amperes and V is the voltage in volts
Solving for the total power:
P = 12 A * 110 V
P = 1,320 Watts
Since the power rating of each hair dryer is 350 W, we divide this to the total power to determine the capacity.
Number of hair dryers = 1,320 Watts/350 Watts per hair dryer
Number of hair dryers = 3.77
In this case, we cannot round off to 4 because this would already exceed the maximum power capacity. Therefore, the total number of hair dryers allowable is 3.
In general? Well one example could be that if you owned an ice rink and somehow the ice had friction, you wouldn't be able to slide around on it any more to skate because the motion between one solid (your feet) and another (the ice) would increase. An effect of friction is heat, but my mixtape already fire so whats that even matter tbh.
