Compare the work you do running versus walking up a set of stairs to reach the third floor. Assume that you start and arrive with zero speed.
a.I do greater work running than walking.
b.The work in the two cases is the same.
c.The height is needed to compare.
d.The mass is needed to compare.
e.I do greater work walking than running.
Homework Answers
Correct option is (a)
work done = change in total energy
Here both cases I am going to the same height so potential energy is going to be same so difference will come due to kinetic energy. while I reached runningly I will have higher kinetic energy as compared to walking so extra work is being done while running rather than walking.

General overview This program will convert a set of temperatures from Fahrenheit to Celsius and Kelvin. Your program will be reading in three double values. The first values are starting and ending temperatures. The third value is the increment value. There is no prompt for the input. There is an error message that can be displayed. This is discussed later. You need to display output for all of the values between the starting and ending values. First two values are...

1) Echo the input: First, you should make sure you can write a program and have it compile and run, take input and give output. So to start you should just echo the input. This means you should prompt the user for the plaintext, read it in and then print it back out, with a message such as "this is the plaintext you entered:". [4 points, for writing a working program, echoing the input and submitting the program on the...

I have completed these but wanting to compare such as Question 14. Is the word "Total" added in the row or written as "Average" or "Total Average" Also Question 8 is not clear what fill color. Is it supposed to stay as blue and just select gradient fill? Very unclear questions. Thank you.
