C)
An automotive engine's camshaft rotates at one-half the speed of the crankshaft.
The correct formula to use is <span>=IF(C2>B2;"Profit";"Loss"). The condition set is that if the selling price(C Column) is greater than the cost price(B Column), you earn a profit. When encoded in the formula, the translation in this statement would be C2>B2. When you use the formula </span>=IF(C2>B2;"Profit";"Loss"), the first word will be shown when the condition set is applicable. <span>In this case, if the condition is true, it displays the word "Profit" but otherwise, it displays "Loss". </span>
Answer:
1. Scanner = reading passports.
2. Barcode reader = automatic stock control.
3. pH sensor = monitor soil in a greenhouse.
4. Microphone = voice recognition.
Explanation:
1. Scanner: Copies paper documents and converts the text and pictures into a computer-readable form. Therefore, it can be used for reading passports.
2. Barcode reader: reads labels containing parallel dark and light lines using laser light or LEDs; the width of each line represents a binary code. Therefore, it is used for automatic stock control.
3. pH sensor: detect changes in acidity levels; data is often in analogue form. Thus, it is typically used to monitor soil in a greenhouse.
4. Microphone: allows audio signals to be converted into electric signals; these can be interpreted by a computer after being converted into digital form. Microphones are used for voice recognition.
