- Two objects (m,- 5.50 kg and m,- 2.70 kg) are connected by a light string passing over a light, frictionless pulley as in the figure below. The 5.50-kg object is released from rest at a point h-4.00 m above the table. (a) Determine the speed of each object when the two pass each other. 3.653 v m/s (b) Determine the speed of each object at the moment the 5.50-kg object hits the table. 6160 V m/s (c) How much higher does the 2.70-kg object travel after the 5.50-kg object hits the table? 1.167 xm ASK YOUR TEbeen having trouble with this, how would you solve this? An electron is injected between two oppositely charged parallel plates connected to a DC voltage supply. The distance between the plates is 6.50 mm and the electron, initially at rest, accelerates towards the positive plate gaining 8.25 ´ 10-18 J of kinetic energy. Based on the above information, what will the mption of electrons be? (uniform motion towards the neg/pos plate, accelerated motion towards neg/pos plate) please explain step by stepA student stands on a thick piece of insulating material, places her hand on top of a Van de Graaff generator, and then turns on the generator.

- A Capacitive Scale. You and your team are tasked with finding a way to electronically measure weight. You get the idea to measure the capacitance between two circular conducting plates of mass m = 0.112 kg and radius r = 11.5 cm separated by a nonconducting vertical spring of spring constant k = 1.35 × 104 N/m and unstrained length do = 3.55 cm. The idea is that the object whose weight is to be determined is placed on the upper plate, thereby compressing the spring and bringing the two plates closer together. This, in turn, changes the capacitance. An electronic instrument that measures capacitance is interfaced with a computer that records the capacitance of the plates and converts it to weight. (a) Your task is to derive an equation for the weight in terms of the capacitance that the computer will use to convert the measured capacitance to weight (in N). Enter your answer in terms of Wo - the weight of the upper plate, C- the capacitance of the capacitor, the variables given above…What is the capacitance of a planet that has mass (5.300x10^23) kg and a diameter of (7.9x10^6) m?
