Question 3 We can make an energy dense capacitor by stacking layers of conductors separated with a dielectric, as shown below. Then, every other layer is connected together and held at the same voltage. V₁ V2 Suppose that all layers are identical and a single pair of plates has a capacitance of 21 F. What is the equivalent capacitance of this setup? Enter your answer in units of [Farads (F) ], rounded to the nearest one.

HEAT TRANSFER CASE:  I want to know what temperature in (°F) the cylinder will have inside. It's a heat transfer problem. what is T2 ? HEAT TRANSFER They gave me an answer all squashed together that i can't make sense of it. If you could help me makes sense of it thank you!

You are working in a biology lab during your summer break. Your supervisor asks you to perform an experiment to find the effective spring constant (in N/m) of a partial molecule of DNA (deoxyribonucleic acid). You perform experiments and find that a single straight portion of a DNA molecule is 2.19 μm long. You then perform an activity that charges the ends of the molecule; each end becomes singly ionized: negative on one end, positive on the other. After the ends are charged, the molecule shrinks by 1.31% of its length. 1.21e-9

Instrumentation & Measurements This homework measures your capability to design/analyze various components/variables of ameasurement system based on what you have studied. Question is Attached in image. Thank you.

Hello, so i have attached two images. the first image is the quetions, i need part b) answered if possible. i have attached my findings to part a) to add to the little information we know to help with part b if needed. Thnks

Q1 please

Record the dimensions of the known (calibration) block using the caliper and dial gauge on the table below. Indicate the units of each measurement. Calculate the average length of each side of the block. Dimension Caliper (Units) 0.995 1.455 0.985 Ruler(in) A: 0.9 B: 1.5 C: 0.9 A B C Dimension A B Instrument Use the average dimensions (see Problem 2a) of the known block to calibrate the LVDT at your workstation. Record the voltage on the table below: LVDT Offset: 0.556 (Do not include the offset value in your average dimensions) C Ave Dimension (Units) (Dial Gauge) 0.997 1.659 0.949 0.964 in 1.538 in 0.945 in oltage Average Dimension 1.244 volt 1.994 1.28 0.964 in 1.538 in 0.945 in

Please do this carefully.

APPLICATIONS OF FIRST ORDER DIFFERENTIAL EQUATIONS Newton’s Law of Cooling and Joint Proportions   At 4:00pm, a thermometer reading of 28 deg C is taken outside where the ambient temperature is –11 deg C. At 4:05 pm, the thermometer reads 8 deg above zero. After a while, the thermometer is returned to the room maintained at 28 deg C. At 4:12pm, the thermometer reads 15 deg C. When was the thermometer returned to the room?

Using the data in Table 18.1, (a) calculate the resistance of an aluminum wire with 5 mm diameter and 5 m length. (b) What is the current flow if the potential drop across the ends of the wire is 0.04 V?

Heat Transfer Design a 1D conduction experiment to measure thermal conductivity of 3 different materials that can be done in your kitchen. Identify the variables that will be changed and write a detailed protocol.

Im not sure how ro go about this, can you help me figure out these answers or how to get these answers?

A chamber of unknown volume is filled with an unknown amount of ideal gas. A cylinder with an open bottom and calibrated volume is connected to the chamber and is closed with a movable piston. A gas pressure sensor is also mounted on the chamber as shown in the figure. The whole experimental setup is kept at a constant temperature of 300 K. Doris moves the piston from mark 0 to mark 200 mL in steps of 50 mL and records the corresponding pressure in the chamber (see the table below). She moves the piston very slowly and waits several minutes before recording the pressure values.   VCyl(mL) P(105N/m2)) 0 4.35 50 3.85 100 3.50 150 3.15 200 2.90   Determine the volume of the chamber using Doris's data in the table. (Note: This is a problem that requires linearization of data.)   Determine the number of moles of gas. (Note: This is a problem that requires linearization of data.)
