Answer:
C. 1/60
Explanation:
Shutter speed is most commonly measured in fractions of a second, like 1/20 seconds or 1/10 seconds. Some high-end cameras offer shutter speeds as fast as 1/80 seconds. But, shutter speeds can extend to much longer times, generally up to 30 seconds on most cameras.
But in this case C. 1/60 is the answer.
Answer:
Whether a traffic light is green, yellow or red
Explanation:
Boolean variables are variables that can either take one out of two options at any given instance.
Analyzing the given options
1. Elevator:
Possible Directions = Up or Down; That's two possible values
But it can only move in one direction at a given instance.
<em>This can be represented using Boolean</em>
2. Traffic Light:
Possible Lights = Green, Yellow or Red
That's three options.
<em>This can be represented using Boolean</em>
<em />
The last two options can be represented using Boolean because they have just two possible values
<em>Hence, option (B) answers the question</em>
