The average speed of a cheetah that runs 140 meters in 5 seconds is calculated by dividing the distance by time, which equals 28 m/s.
To calculate the average speed of a cheetah running a distance of 140 meters in 5 seconds, we use the formula for average speed which is:
Average Speed = Distance / Time
Substituting the given values of distance and time in this equation, we get:
Average Speed = 140 meters / 5 seconds
Solving this, we obtain the average speed of the cheetah as 28 m/s.
The average speed is a scalar, meaning we do not include direction in the answer. For comparison purposes, the speed of a typical automobile might be around 15 m/s.

Answer: C) Unscrew one light. If the other lights turn off, it's a series circuit.
Explanation:
In a series circuit, all the components in the same path. The current in the entire circuit is same. The voltage drop across each component is different. If one component does not work, the entire circuit breaks and other components also stop working. On the other hand, in a parallel circuit, voltage drop across all the components is equal. Trouble in one component does not effect other components.
Hence, to check whether the lights are connected in series or in parallel, one light should be unplugged and if the other lights still work, it means they are connected in parallel otherwise in series. Thus, correct option is C) Unscrew one light. If the other lights turn off, it's a series circuit.
