A student in a noon calculus class is watching two bugs near the center of a wall. One is an ant and the other is a beetle. At noon, the ant is 180 cm directly to the left of the beetle. The ant is crawling right at 30 cm/h and the beetle is crawling up at 45 cm/h. How fast is the distance between the bugs changing at 2:00 PM? Answer with an exact value. cm/h?

Using Python Define a Student class. A Student class needs to have two attributes, the student_name and strudent_grade . It also has three methods as follows: set_grade(grade) that sets the grade of the student. get_grade returns the grade of the student. print_student_info that print the name and grade of student in a formatted string. In the math_utils.py file define a function called average_grade(roster) . This method accepts as input a list of Student Objects and returns the average of the...

Near the equator, the Sun is approximately straight overhead at noon, and around 1000 W/m2 solar irradiance reaches Earth. Around this time of day, assuming ambient temperature of 40C, and a 10m x 10m x 2m-tall greenhouse with ¼”-thick glass walls that reflect away 20% of the incoming sunlight, and only thinking of conductive losses, estimate the maximum temperature reached in the interior of the greenhouse. Hint: when are losses and sources balanced? glass conductivity is 1.05 W/(m k)

There are three ways a student can end up in Calculus II at Augusta University. They can either take Calculus I or place into the class via AP credit. Further, some students take Calculus I the semester immediately before Calculus II but some students wait one or more semesters between taking Calc I and Calc II. A professor has a Calculus II class with 21 students, and they look at students’ final grades and how they got into the class....
