Can someone help me with this electricity question

Answers

Answer 1

Answer: "Cutoff" means that the base current is biased in such a way that the
collector-emitter current is cut off ... zero current through the transistor.

"Saturation" means that the base current is biased in such a way that
the collector-emitter current is the most it can be ... max possible
current through the transistor.

-- In order for the motor to run, there has to be some emitter current.

-- The transistor is a current amplifier. In order to get any emitter current,
you'll need a little bit of base current.

-- The way the circuit is built, there's no way to get any base current.
Grounding it doesn't do anything.

-- Leave the switch where it is. But disconnect the resistor from
ground, and connect it instead to the top of the battery (the collector
terminal is a convenient place). Then, when the switch is closed, the
base gets some current from the battery through the resistor, big current
appears through the collector-emitter, and the motor spins up.

An example of software is a spreadsheet :)

Answer: B) Spreadsheet

Explanation:

A spreadsheet or worksheet is a file made of rows and columns that help sort, organize, and arrange data efficiently, and calculate numerical data. What makes a spreadsheet software program unique is its ability to calculate values using mathematical formulas and the data in cells.

C. Following the given instructions, create a grade calculator using MS Excel. The grade calculator should allow you to enter your assignment marks/ grades and calculate your overall grade for a specific course. ∙ Create a new Excel workbook and name it "Grade Calculator."
∙ Set up the following column headers in cells A1 to C1:
∙ A1: Assignment Name, B1: Max Score, C1: Your Score
∙ In the subsequent rows, enter the names of the assignments, their maximum scores, and obtained scores.
∙ Create a formula in column D (cell D2) to calculate the percentage for each assignment using the formula: (Your Score / Max Score) * 100.
∙ Create another column (column E) and use conditional formatting to assign letter grades based on the following scale:
∙ 90 or above: A, 80-89: B, 70-79: C, 60-69: D, Below 60: F
∙ In cell E1, enter "Grade" as the column header.
∙ Calculate the overall course grade by averaging the percentages of all assignments. Place this average in cell D6 and apply appropriate formatting to display it as a percentage.
∙ Calculate the corresponding letter grade for the overall course grade in cell E6 using the same conditional formatting rules mentioned above.
∙ Save the Excel workbook with an appropriate name.
