• Experiment is do slugs prefer plant based foods or animal protein?

• Think about an experiment you could run to test your hypothesis. What would be the variable(s) in your particular experiment? For each variable that you identify, say whether it would be considered an independent- or dependent variable. Also, say whether it would be considered a quantitative- or qualitative variable. Explain your reasoning for assigning each variable as quantitative or qualitative. Hint: See pp. 2-3 for help on identifying variables.

• Come up with at least three extraneous variables that you would have to control for (i.e. variables that you are not testing for, but could possibly affect the results/interpretation of your experiment). For example, if you hypothesized that slugs are more likely to feed on greasy foods, then think of over variables, besides the food’s greasiness, that might influence your results.

• Come up with a step-by-step (and detailed) procedure for an experiment you could run to test your hypothesis (attach additional sheets if necessary). Make sure you can perform this experiment using only the materials available to you (since this is being made up, you can have whatever materials you want). As part of your procedure, describe how you would control for the variables you listed in question #7. Also describe how you will quantify food consumption by the slugs.

Here are some things to consider when coming up with your procedure:

•Your slug(s) will feed inside the provided plastic container until the next lab meeting.

• Come up with a way on how you can quantify the amount of feeding that takes place. In other words, see if you can come up with a way of making the amount of feeding a quantitative variable.

•Make sure to put enough water to just cover the bottom of your container. Slugs can live only in moist environments.

•Make sure to wear gloves when handling slugs. Then, take off the gloves before you handle anything else. This will prevent slug slime from getting on everything.

Animation—The Millikan Oil Drop Experiment
Watch the animation to study the Millikan oil drop experiment.
Click to launch the animation
The Millikan oil drop experiment was a direct and convincing experiment for the measurement of the charge on a single electron. Millikan performed an experiment on a charged oil droplet. By balancing the forces acting on the oil droplet, the charge on a single electron can be calculated. Millikan found that the charge of an oil droplet is always a whole-number multiple of −1.60×10−19 C. Thus, the charge on a single electron is −1.60×10−19 C.
Various types of forces that are observed in nature
You can observe the following types of forces in nature:
The attraction or repulsion between objects or particles that have electrical charge is known as the electric force.
The force with which the Earth, the Moon, or any other massively large object attracts another object toward itself is known as the gravitational force.
The force exerted upon an object that is in contact with another stationary object is known as a normal force.
The special type of frictional force that acts upon objects as they travel through the air is known as an air resistive force.
The force exerted by a compressed or stretched spring upon any object that is attached to it is known as a spring force.
The upward force caused by the air pressure that keeps things afloat is known as a buoyant force.
Part A - The forces acting on an oil droplet
Watch the animation. Identify the types of forces acting on an oil droplet while the voltage is turned on and the droplet is either falling or rising.

Part B - The effect of an electric field (voltage) on a negatively charged oil droplet
In the Millikan oil droplet experiment, the oil is sprayed from an atomizer into a chamber. The droplets are allowed to pass through the hole into the chamber so that their fall can be observed. The top and bottom of the chamber consist of electrically charged plates. The upper plate is positively charged, and the lower plate is negatively charged. X rays are introduced into the chamber so that when they strike the oil droplets, the droplets will acquire one or more negative charges. The electric field (voltage) is applied to the metal plates.
Watch the animation and identify the effects of an electric field on the motion of a negatively charged oil droplet. Consider the gravitational force as Fg and the electric force as Fe. All the other forces acting on the oil droplet can be ignored as their effect on the motion of the oil droplet is negligible.
Check all that apply.
Hints
Check all that apply.
If Fe is increased until it is equal to Fg, the negatively charged oil droplet will remain stationary.
In the absence of an electric field, the oil droplet falls freely due to the gravitational force.
In the presence of an electric field, the negatively charged oil droplet moves freely toward the negatively charged plate.
If Fe is greater than Fg, the negatively charged oil droplet will move freely toward the negatively charged plate.

Part C - The total charge on a negatively charged oil droplet
In Millikan’s experiment, the oil droplets acquire one or more negative charges by combining with the negative charges that are produced from the ionization of air by X rays. By measuring the charges on the oil droplets, he calculated the charge on a single electron as −1.60×10−19 C. The charge on any negatively charged oil droplet is always a whole-number multiple of the fundamental charge of a single electron.
If Millikan was measuring the charge on an oil droplet with 7 negatively charged electrons on it, what charge would he have measured on the droplet?
Express your answer to three significant figures and include the appropriate units.

On June 5, 2019, Javier Sanchez purchased and placed in service a new 7-year class asset costing $560,000 for use in his landscaping business, which he operates as a single member LLC (Sanchez Landscaping LLC). During 2019, his business generated a net income of $945,780 before any § 179 immediate expense election. Rather than using bonus depreciation, Javier would like to use § 179 to expense $200,000 of this asset and then use regular MACRS to cost recover the remaining cost.

Complete Javier's Form 4562 (page 1) for 2019.
Note: For 2019, the maximum § 179 is $1,020,000 and the threshold amount is $2,550,000. If an amount is zero, enter "0". Enter amounts as positive numbers.
