To Explain: Whether a shadow of the airplane would appear at the center of the circle, if a rainbow viewed from an airplane may form a complete circle.

Explanation of Solution
Introduction:
The rainbow is formed when light disperses from the suspended water droplets and that is in the right place for the rays to enter into the eyes.
Explanation:
It is not possible to have a complete circle of the rainbow as seen from someone standing on the ground. But from aircraft, one could possibly be able to look down on water droplets in the atmosphere and can see a circular rainbow.
When the rainbow is viewed from the airplane, airplane is between the Sun and rainbow. Thus, the shadow will be formed on the same side of the rainbow and formed at the center of rainbow circle.
Conclusion:
The shadow will be formed on the same side of the rainbow and formed at the center of the rainbow circle.

- Four charges, qa, qb, qa, and qd are fixed at the corners of a square. A charge q that is free to move located at the exact center of the square. Classify the scenarios described according to the force that would be exerted on the center charge q. Assume in each case that q is a positive charge. Do not assume that the fixed charges have equal magnitudes unless the scenario defines such an equality. qa Яс q %b Force is zero Force is to the left Force is to the right Force is undeterminedarrow_forwardCharge qi = -q is located at position (0, d).

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.

- When an electromagnetic wave is reflected at normal incidence on a perfectly conducting surface, the electric fieldvector of the reflected wave at the reflecting surface is the negative of that of the incident wave.a) Explain why this should be so.b) Show that the superposition of the incident and reflected waves results in a standing wave.c) What is the relationship between the magnetic field vector of the incident and reflected waves at the reflectingsurface?arrow_forwardSuppose 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.arrow_forwardIn 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? hel lp?arrow_forward
- 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? 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?? Best Regards, Yahyaarrow_forwardGiven 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_forward
