1. consider the falling and rolling motion of the ball in the following two resistance-free situations. in one
situation, the ball falls off the top of the platform to the floor. in the other situation, the ball rolls from
the top of the platform along the staircase-like pathway to the floor. for each situation, indicate what
types of forces are doing work upon the ball. indicate whether the energy of the ball is conserved and
explain why. finally, fill in the blanks for the 2-kg ball.

Jonathan pays $1.90 per pound for potatoes. he buys 8.3 pounds of potatoes. he determines that he will pay $15.77, before tax, for the potatoes. which best describes the reasonableness of jonathan’s solution? jonathan’s answer is reasonable because there are two decimal places in the factors and two in the product. jonathan’s answer is unreasonable because there are three decimal places in the factors and two in the product. jonathan’s answer is reasonable because is 16, and 16 is close to 15.77. jonathan’s answer is unreasonable because is 8, and 8 is not very close to 15.77.

Whit h equation best represents this situation the number 98 increased by an unknown number equal to 120

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
