An independent-samples t-test provides the following data: Size of sample A is 12, size of sample B is 12; sample variance for sample A is 16.5, sample variance for sample Bis 19.1
What is the pooled variance?

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).
