A group of students measures the length and width of a random sample of beans. They are interested in investigating the relationship between the length and width. Their summary statistics are displayed in the table below. All units, if applicable, are millimeters. Mean width: 7.589 Stdev width: 0.888 Mean height: 12.623 Stdev height: 1.768 Correlation coefficient: 0.8368 a) The students are interested in using the width of the beans to predict the height. Calculate the slope of the regression equation...

An interference pattern from a two-slit experiment with light has a spacing between the central (brightest) peak and the neighboring peak of 3.3 mm. The distance from the slits to the screen is 1.5 m and the wavelength of the light is 690 nm. a) What is the angle between the central maximum and its neighbor? Express your answer in degrees. b) What is slit spacing, d? Please give this distance in millimeters.

The column of a mercury barometer is calibrated in linear units
(such as inches or millimeters) and thus the air pressure observed
on such a barometer is reported in terms of these linear units.
This measurement of pressure can be converted to other common
pressure units. Some conversion factors are shown here.
1mm Hg = 1torr
1 atm = 760mm Hg
1 atm = 1.01325 bar
1 Pa = 10-5 bar
1 in = 2.54 cm
1 cm = 10...

In this experiment, the ball is launched horizontally. You measure the horizontal distance between the launcher and the spot where the ball hits the ground to be 1.54 m. The launcher is at a height of 87 cm above the ground. What is the speed at which the ball leaves the launcher? Write your answer in m/s to 3 places of decimal. (answer correct to +- 3% will be acceptable)

In this experiment, the ball is launched horizontally. You measure the horizontal distance between the launcher and the spot where the ball hits the ground to be 1.36 m. The launcher is at a height of 102 cm above the ground. What is the speed at which the ball leaves the launcher? Write your answer in m/s to 3 places of decimal. (answer correct to +- 3% will be acceptable)
