LAB-7 physics

I’m trying to see what are the steps to answer the question.

Clear Explanation on this question add some step to leading to this how you get this answer neat handwriting and clear explanation difficult so please double check answer have a 2m rod that has been charged to 4C, and a 1m rod that has been charged to -6C. can place them anywhere on the x-axis (i.e. they are parallel to the x-axis) subject to the following rules: • The rods cannot be touching. • The rods cannot occupy the same space. a) Draw your system on a Cartesian plan (with labeled axes). b) Pick any point on the axis that is not being occupied by the rods. Clearly label it. c) Determine the field at this point. d) Determine the voltage at this point.

What are the expected voltages of C and D of this circuit?

What is the correct way to measure current in a completed circuit using a DMM? O Connected in series to the circuit being tested. O Connected in parallel to the circuit being tested. Connected across the load device in the circuit being tested. Connected in placed of the load device in the circuit being tested.

A voltage source an IR drop of 40 volts across a 20 ohms R1, 60 volts across a 30 ohms R2, and 180 volts across a 90 ohm R3, all in series. How much is the applied voltage?

Two lamps x and y are hanged at a distance 12 ft between their centers, Lamp x gives 140 cp and 7 ft above the working space while lamp y gives 200 cp and 5 ft above the working space. At what distance from a point directly below lamp x on the line joining their centers will the two lamps give equal amount of illumination

Meter Questions These questions address how to use and read the Simpson and Fluke DMM when measuring resistance. You can get assistance by referring to the meter manuals included at the end of your course packet. If you have any questions, ask one of the Lab staff members. Simpson Model 260 Volt-Ohm-Milliammeter 1. What are the three resistance ranges available on the Simpson meter? When changing resistance ranges on the Simpson meter, the meter must be zeroed using the Zero Ohm's Adjust knob. What is/are the reason(s) for this step? 2. 3. Where is "OQ" on the meter scale – on the left or right end? a. Left b. Right 4. Is the Simpson meter more accurate at the left or right end of the OHMS scale? a. Left b. Right C. The meter has the same accuracy across the entire OHMS scale A meter is set to the "Rx100" setting and the needle is pointing to "200" on the OHMS scale. The technician changes to the Rx10,000 setting and the pointer settles over "1.8". Which is the more accurate reading?…

Can you show the circuit for this or the diagram?

107) Which of the following describes a voltage drop test? O Connecting the (-) DMM lead battery positive and connecting the DMM (+) lead to battery negative. Connecting the DMM lead to the battery negative terminal and connecting the DMM lead to a good engine or chassis ground. O Connecting both DMM leads to the negative terminal of the battery. Connecting the DMM lead to the battery positive terminal and connecting the DMM lead to a good engine or chassis ground.

A car lot uses incandescent lamps to supply outside lighting during the night. There are three strings of lamps connected to a single 20-ampere circuit. Each string contains eight lamps. What is the largest standard lamp that can be used without overloading the circuit? Standard size lamps are 25 watts, 40 watts, 60 watts, 75 watts, and 100 watts.
