Consider the arrangement of charges shown in the figure. Four charges of equal magnitude Q but varying sign are placed at the
corners of a square as indicated. A positive charge q is placed in the center.
What is the direction of the net force, if any, on the center
charge? Indicate your answer by placing the appropriate label
in the first box.
Then, suppose that the charge q were to be displaced slightly
from the center position. On the figure, label each box with
the arrow that best indicates the direction of the net force that
would act on q if it were moved to that location.

In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the primary of the transformer. The secondary is connected to the primary of another step- down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using? Remember that the current and voltage given in this problem are rms values.arrow_forward
- In some places, insect "zappers," with their blue lights, are a familiar sight on a summer's night. These devices use a high voltage to electrocute insects. One such device uses an ac voltage of 3970 V, which is obtained from a standard 120-V outlet by means of a transformer.

Bestarrow_forwardDear Scientist in physics , How are doing, my name is Yahya from Saudi Arabia and currently in my first semester to pursue Master's degree in physics. I have been watching all interviews of some scientists in physics on YouTube Channel and somthing has got my mind. I studied my bachelor 's degree in biology and I have been contacting Professor's Bruce Lipton many times and he explained epigenatic well. He was talking about physics many times. He said if you want to understand who we are and how we think, you need to understand Physics well. So I have decided to study physics. I have some questions : Why is the community of physics are divided? What is the difference between Quantum physics, quantum field theory, Quantim theory, and classical physics? What is quantum consciousness theory as well. What do they mean by wave function collapse? Why professor Roger's always has another opinions in quantum consciousness theory??

- Given water's mass of 18g/mole and the value of the fundamental charge (charge magnitude of the electron and proton), use the largest charge density from the article to determine what fraction of water molecules became ionized (charged) due to triboelectric effects when it flows through the material that causes the largest charge transfer. Give your answer in e/molecule, or electrons transferred per molecule of water. For instance, a value of 0.2 means only one in five molecules of water loses an electron, or that 0.2=20% of water molecules become chargedarrow_forwardno AI, pleasearrow_forwardSketch the resulting complex wave form, and then say whether it is a periodic or aperiodic wave.arrow_forward
- During a concentric loading of the quadriceps muscle in the upper leg, an athlete extends his lower leg from a vertical position (see figure (a)) to a fully extended horizontal position (see figure (b)) at a constant angular speed of 45.0° per second. Two of the four quadriceps muscles, the vastis intermedius and the rectus femoris, terminate at the patellar tendon which is attached to the top of the tibia in the lower leg. The distance from the point of attachment of the patellar tendon to the rotation axis of the tibia relative to the femur is 4.10 cm in this athlete. a b (a) The two quadriceps muscles can exert a maximum force of 225 N through the patellar tendon. This force is applied at an angle of 25.0° to the section of the tibia between the attachment point and the rotation axis.

The rope goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R₁ = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is μk = 0.250. At the instant shown, the block is moving with a velocity of v; = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the rope does not stretch and does not slip on the pulley, and that the mass of the rope is negligible. mq R₂ R₁ mi (a) Using energy methods, find the speed of the block (in m/s) after it has moved a distance of 0.700 m away from the initial position shown. m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this…arrow_forwardno AI, pleasearrow_forward
