A cheetah has a mass of 50kg and can accelerate at 10 m/s2. This is equal to 500 Newtons which is the force the cheetah creates to run. Let's calculate how much work the cheetah does and how much power it generates when it runs 50 meters in 3 seconds.

Step 1: Determine how much work is done (measured in joules).

Multiply the force by the distance 500N×50meters= _______ joules



Step 2: Determine the power (measured in Watts).

Divide the work by the time it took to do the work 25,000joules÷3s.= _______ watts

The new machine is a quality improvement strategy that will reduce the probability of errors.

Answer:

In Python:

entry = input("Sentence: ")

while True:

   if entry.count(",") == 0:

       print("Error: No comma in string")

       entry = input("Sentence: ")

   elif entry.count(",") > 1:

       print("Error: Too many comma in input")

       entry = input("Sentence: ")

   else:

       ind = entry.index(',')+1

       if entry[ind].isnumeric() == False:

           print("Comma not followed by an integer")

           entry = input("Sentence: ")

       else:

           break

print("Valid Input")

Explanation:

This prompts the user for a sentence

entry = input("Sentence: ")

The following loop is repeated until the user enters a valid entry

while True:

This is executed if the number of commas is 0

   if entry.count(",") == 0:

       print("Error: No comma in string")

       entry = input("Sentence: ")

This is executed if the number of commas is more than 1

   elif entry.count(",") > 1:

       print("Error: Too many comma in input")

       entry = input("Sentence: ")

This is executed if the number of commas is 1

   else:

This calculates the next index after the comma

       ind = entry.index(',')+1

This checks if the character after the comma is a number

       if entry[ind].isnumeric() == False:

If it is not a number, the print statement is executed

           print("Comma not followed by an integer")

           entry = input("Sentence: ")

If otherwise, the loop is exited

       else:

           break

This prints valid input, when the user enters a valid string

print("Valid Input")

Note that: entry = input("Sentence: ") is used to get input

to format a cell based on the value in it

Explanation:

you would use conditional formatting on a cell when you want to format a cell based on the value in it.

Reason -

Conditional formatting allows you to format a cell based on the value in it.

For example, if you want to highlight all the cells where the value is less than 30 with a red color, you can do that with conditional formatting.

Explanation:

OrderID + ProductID is an example of a composite key in a database table. The correct option is 4.

A composite key is a key in a database table that consists of two or more columns that uniquely identify each row.

In a database table, a composite key is the combination of OrderID and ProductID in a table that tracks sales transactions.

Because a single order can contain multiple products and multiple orders can contain the same product, neither column can uniquely identify a row by itself.

However, by combining the two columns, each row can be uniquely identified, ensuring that the data is accurate and complete.

Similarly, a combination of CustomerID and ProductID might be used in a sales system to track the products purchased by each customer.

Thus, the correct option is 4.

Name:This field has 5 to 10 characters and accepts text data only.

Date of Birth: This field accepts dates only. It uses a medium-length entry in the form of month/day/year (mm/dd/yy).

Age: This field is numerical and contains numerical data only.

Blood Type: This field contains text data, with a maximum of 11 characters.

Hobby: This field can be a memo, and it can accept large volumes of data in any format. This data type can include null values as well.

Talent Show Registration: This is a Boolean data field that contains the values Yes or No.

Unique ID: This field accepts alphanumeric data, so this, too, is a text field.

Answer:

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

class Window //defining a class Window

{

private:

int width, height;//defining integer variable

public:

friend ostream& operator << (ostream& stm, Window& width)//defining a friend function that takes two parameters

{

return stm<<"a ("<<width.width<<" x "<<width.height<<") window"; //use return keyword that return its values

}  

Window(int width, int height): width(width), height(height)//defining parameterized constructor that inherit width and height in its parameters  

{}

};

int main() //Main method

{

Window w(80,90);//calling class constructor

cout<<w;//print object value

return 0;

}

Output:

a (80 x 90) window

Explanation:

In the above code, a class "Window" is defined that uses a friend function "ostream& operator" is declared that uses the "ostrea&" as a data type to hold two-variable "stm and w" in its parameter, and declared the parameterized constructor to hold value by inheriting width and height in its parameters.

Inside the main method, a class object is created that calls the constructor and uses the print method to print object value.

Answer:

Best: Option 4

Worst: Option 1

Explanation:

The co-worker might be oblivious to the detrimental effect of his actions on work atmosphere. Talking to him and telling him to stop is the first step to improve this.

Option 2 is not as effective, as the co-worker would not know the reason and might just talk behind people's backs to other people, thus no actual progress would be made, except less communication overall.

Option 3 is likely to antagonize people, with the engineers being unhappy about your co-worker, and the co-worker being mad at you for telling on him. This option is the most likely to end up with someone leaving the job.

Option 1 is just expanding the circle of bad behavior, hence probably the worst possible.
