Think of something you are interested in exploring, and design an experiment. (You will not actually conduct the experiment, so feel free to be creative.) Identify the following aspects of your experiment: 1. Independent Variable 2. Dependent Variable 3. Operational 4. Definition of Subjects within the population 5. Experimental Group 6. Control Group 7. One Potentially Confounding Variable8. Two Methods Used to Control for Bias

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u. s. legal proceeding.)

Why do electron microscopes have higher resolving power than light microscopes?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
