A meter stick is made out of aluminum. The scale is accurate at 40°C. Suppose an intrepid student living in Alaska takes the meter stick outside on a very cold winter day to measure the length of a concrete paving stone with dimensions of 10 inches by 10 inches at 40°C. What length will the student measure, if the outside temperature is −46°C? (Give your answer in cm at −46°C. Round your answer to at least two decimal places.)

As you are headed to class, your friend leans out the window of your apartment 16 m above you and shouts that you took her car keys rather than your own. Since you are in a hurry, you decide to toss your friend’s keys up to her while she drops your keys down to you. You throw the keys just hard enough to reach her outstretched hand. At what height above you will the two sets of keys pass each...

1. Suppose that you are on a spaceship traveling at a constant velocity of 0.770c. While riding along inside the spaceship, you measure the length of your own ship (in the direction of motion) to be 100. meters long a. As you speed past the Earth at constant velocity, what do observers on Earth measure the length of your spaceship to be? A. 53.8 m B. 63.8 m C. 73.8 m D. 83.8 m E. 93.8 m b. As you...

1. Suppose that you do not know your true success rate at basketball free throws. Out of the 17 attempts, you were able to make 9 of them. a) What is the point estimate associated to the true probability of success p? (4 decimals) b) What is the standard error associated to this estimate? (4 decimals) 2. Suppose that you claimed to someone that you can make basketball free-throw shots 80% of the time. Someone didn't believe you with a level of...

Your friend, Sally Geek again, knows you are taking physics 132 at Calpoly Pomona. She invites you to go on a long journey with her into space in her small spaceship of mass 1000kg. Using thermodynamics approach, she tells you that stellar bodies can be assumed to have an average mass of 1030kg ( mass of the sun ), and to move with a random velocity of 10 km/s. She wants to know the average velocity the rocket will reach...

Question: Suppose your friend April is considering to refinance her mortgage. She bought her house 60 month... Suppose your friend April is considering to refinance her mortgage. She bought her house 60 months ago. The amount of loan equals 196,000. She paid cash to cover the 5% down payment plus all required closing costs (closing costs include application fee, appraisal fee, loan origination fees and other costs, usually about 3%-5% of the loan amount). Since she had a decent credit...
