Suppose there are two transformers between your house and the high-voltage transmission line
that distributes the power. 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.
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. If the primary coil has 27 turns, how many turns are in the
secondary coil?

Hi,
Does Quantum physics theory means all branches for example quantum relativity, Quantum mechanics, Quantum field theory, and string theory? Can you explain each one of them?

- Dear 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??

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.

A feedback mechanism senses the angular speed of the disk, and a drive motor at A ensures that the angular speed remain constant while a m = 1.20 kg block on top of the disk slides outward in a radial slot. The block starts at the center of the disk at time t = 0 and moves outward with constant speed v = 1.25 cm/s relative to the disk until it reaches the edge at t = 360 s. The sliding block experiences no friction. Its motion is constrained to have constant radial speed by a brake at B, producing tension in a light string tied to the block.
