Two blocks, A and B, are made of the same material. Block A has dimensions $l \times w \times h = L \times 2L \times L$ and Block B has dimensions $2L \times 2L \times 2L$. If the temperature changes, what is the change in the volume of the two blocks? A. The change in volume of Block B should be 8 times the change in volume of Block A. B. The change in volume of Block B should be twice the change in volume of Block A. C. The change in volume of Block B should be 4 times the change in volume of Block A. D. The change in volume of Block B should be the same change in volume of Block A.

Postpartum depression and anxiety (PPD), is a common medical condition affecting mothers and their families after the birth of a baby. The CDC estimated that $ 19 \% $ of women who have recently given birth suffer from PPD. However, this research only reflected self-reported cases. Therefore, one group dedicated to helping women and their families with PPD believes that the true percentage of women who suffer from PPD is much higher. The group conducts a simple random sample of 135 women who had given birth in the last year and discovers that 34 of them report having PPD. Based on this evidence, can the group claim that the true percentage of women who have PPD is greater than $ 19 \% $ ? Use a 0.05 level of significance. Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places. Answer Tables Keypad

Question 3 1 pts Fill in the following blanks numerically. Use integers or fractions (ex: -1/2, 0, 1, 3/2, 2). Include a sign if necessary. The molecular orbital diagram for H$_2$ has elecrons in the sigma bonding orbital and elecrons in the sigma antibonding orbital. Therefore, molecular orbital theory would predict a bond order of for H$_2$.

Texts: A stuntman wearing a jetpack walks off the edge of the Hancock Tower in Boston, 241 meters above the ground. The stuntman is in freefall (starting from rest, vertically) until he reaches a certain height H above the ground, when he switches on the jetpack. Use g = 9.80 m/s^2. A) Assume the jetpack (when it is on) gives the stuntman a net upward constant acceleration with a magnitude of 1.50 g. If the stuntman wants to time the turning on of the jetpack so that he reaches the ground with a velocity of 0 m/s, at what height H should he turn on the jetpack? _______ m B) What is the stuntman's maximum speed during the trip? _______ m/s C) What is the total time it takes the stuntman to go from the top of the Hancock Tower to the ground? _______ s
