Here is the data of carpet shocks -
0.04mJ - Spark threshold, visible in darkness .
1.2 mJ- Winter doorknob spark, small snap, little pinprick
3.7 mJ - Fairly nasty spark, louder snap.
12-6 A child slides across a floor in a pair of rubber-soled shoes. The frictional force acting on each foot is 20.0 N. The footprint area of each shoe sole is 16.0 cm2, and the thickness of each sole is 4.10 mm. Find the horizontal distance by which the upper and lower surfaces of each sole are offset. The shear modulus of the rubber is 3.00 ✕ 106 N/m2.
Estimate the amount of energy Δ? released in a typical “finger‑to‑door knob” spark after a person walks across a carpet in rubber‑soled shoes.

The human body can exhibit a wide range of resistances to current depending on the path of the current, contact area, and sweatiness of the skin. Suppose the resistance across the chest from hand to the right hand is 1.55 x 106 Ω. (a) How much voltage is required to cause possible heart fibrillation in a man, which corresponds to 490 mA of direct current? (b) Why should rubber-soled shoes and rubber gloves be worn when working around electricity? This...

10. Use Rubber Balls in a Box Setup. Suppose 5 rubber balls are to be randomly drawn out (all at once). Find the probability that the numbers on the rubber balls will be sequential (when, after drawing, the numbers are arranged lowest to highest). This is a short answer question. The correct answer is a fraction. It is NOT NECESSARY to simplify the answer. 11. Use Rubber Balls in a Box Setup. Suppose 3 rubber balls are to be randomly...
Which of the following is true about a rubber baseline? A rubber baseline is a best practice in baseline maintenance that that improves management visibility. A rubber baseline can mask near-term cost variances, impacting management's ability to take timely corrective action. A rubber baseline has no effect on cost variances because scope, schedule, and budget are moved together. A rubber baseline typically evens out cost variances over the life of the contract and is therefore considered a best practice.
Place yourswlf in Annies shoes, the physcians shoes, and Daniels shoes, and then discuss how the lives of each may have been different if the physician had informed Annie as to the seriousness of her illness.
