Masses m and 3m are connected via a rope, which passes over a frictionless pulley. If this system is released from rest, what is the acceleration of the mass m? Assume the acceleration due to gravity is ay = –g. Hint: the tension in the rope has the same magnitude on both sides of the pulley.

In two minutes, an ant covers a distance of 8.00 yards. What is that distance measured in centimeters [cm]? Recall that 1 m = 100 cm.

A lioness stalking a zebra goes from sitting still to her top speed v in time t. She then spends time 5t at her top speed until she catches her prey. If this motion was all along a straight line, what is the total distance the lioness traveled?

Write a C++ program that: · Reads an integer number from the user. · Displays the result of a pre-increment operation. · Displays the result of a post-decrement operation. · Calculates and displays the result of multiplying the final value by 2. · Uses an if-else if-else statement with logical operators to determine:     o If the final value is greater than 10 and less than 20, display “Range 1”.     o Else if the final value is less than or equal to 10 or equal to 25, display “Range 2”.     o Otherwise, display “Range 3”.

Write a C++ program that: · Reads an integer number from the user. · Displays the result of a pre-increment operation. · Displays the result of a post-decrement operation. · Calculates and displays the result of multiplying the final value by 3. · Uses an if-else if-else statement with logical operators to determine:      o If the final value is greater than 15 and less than 30, display “Range 1”.      o Else if the final value is less than or equal to 15 or equal to 35, display “Range 2”.      o Otherwise, display “Range 3”.

The letter C represents hydrogen atoms and the letter D represents atoms in A bond occurs at B and a bond occurs at A

Please match the numbers with the correct description, function, or organ.

Compare and contrast mitosis and meiosis. In your answer, state whether the final cells are diploid or haploid, and how many chromosomes are found in human cells after each process. Be sure to include the major phases. Your answer should also describe whether the cells produced are genetically identical or genetically different. Lastly, what type of cells go through mitosis vs meiosis? Your answer should be written as one complete paragraph or a list of bullet points using correct biology vocabulary.

What type of bond(s) occur with sharing electrons between atoms?
