Assume that you have a configuration of conductors with varying electric potentials applied to each, such as you will be dealing with in this lab. you make the following measurements of the values of the electric potential at different points in a dimensional grid: x = 0.00 cm y = 0.0 cm v = 2.0 volts x = 0.00 cm y = 0.00 cm v = 2.25 volts x = 0.00 cm y = 0.00 cm v = 2.0 volts what are the values of the x and y components of the electric field at the origin (e_x and e_y at (x, y) = (0, express the results in si units. for on doing this problem, read question 1 -6 in this lab writeup.

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
