Gamma rays are the shortest and strongest waves of light. We can see visible light, a very short part of the spectrum. What if we could see gamma rays, what would it look like? Also, if you could see through objects with X-Ray vision (not sure if this is true) could you also do the same with gamma ray vision? And would the daily occurences of gamma ray bursts in the universe blind you by looking directly at them should they happen to be on your horizons, kind of like looking at the sun?

The voltage and the current in the primary coil of a nonideal transformer are 120 volts and 2.0 amperes. The voltage and the current in the secondary coil are 19.4 volts and 11.8 amperes. What is the efficiency of the transformer? The efficiency of a transformer is defined as the ratio of the output power to the input power, expressed as a percentage e=100Pout/Pin

First, you may have learned from physics that energy can't be created or be destroyed, and it can only be transferred from one place to another. Second, as most of us know, when one is asleep, time seems to pass very quickly. Once you fall asleep the next second when you wake up, many hours have passed. In extreme cases, when one is in a coma, a person may experience a lifetime in a matter of hours from the time the person become unconscious to when he/she awakes decades later. In theory, I think in religious term "a soul" is pure energy. It cannot be created or destroyed, but transferred from one place to another. When we die, the energy migrates from our body to another body where we establish conscious again. . During migration, the soul has no conscious because it doesn’t have any means to process and store information. It cannot process any of the five senses (touch, hear, see, smell, and taste). In this state, the soul is auto-piloting in total darkness. This migration may take years, decades, or even millions of years, but to the eye of the beholder, it's a matter of seconds.

Also, It can be said that the conscious is a lit light bulb, the cable is the body, and the battery is the soul. The light bulb lights up when the cable is wired and connect to a battery. The cable gets hot from running long hours and need to cool down. The battery reduces electricity output to let the cable and light bulb cool down while it recharges. If the cable is broken or deem unusable, you lose conscious completely that’s when you die. However, the battery and light bulbs remain intact waiting to be connected again. With time and randomization of events, the cable mends or a new cable comes along we establish conscious again.

A tennis ball of mass 0.0610 kg is served. It strikes the ground with a velocity of 52.5 m/s (117 mi/h) at an angle of 21.6° below the horizontal. Just after the bounce it is moving at 50.5 m/s at an angle of 17.9° above the horizontal. If the interaction with the ground lasts 0.0693 s, what average force did the ground exert on the ball?

If it was possible to dig a hole from the top of the earth to the bottom and jump straight through, would you come out on the other side, feet first? head first? or would you be stuck levitating in the middle? of course this is assuming there is no core and you could not be crushed by gravity and etc....

Radio waves are the longest and weakest waves of light. We can see visible light, a very short part of the spectrum. What if we could see radio waves, what would it look like? Would the radio waves flying around everywhere from radio stations bombard our senses, annoy us, or not bother us at all? What exactly would we be seeing? How would it be in conjunction to being able to also see visible light, and how would it be if we could only see radio waves?

Put the following regions of the electromagnetic spectrum in order of increasing energy: gamma rays, infared, tv waves, ultra-violet waves, visible, radio waves, microwaves

This is the order
Radio waves, microwave, infrared, visible, ultraviolet, x-ray, and gamma ray radiation.

But I do not know where TV rays fit in the energy order?

A planet moves in an elliptical orbit around the sun. The mass of the sun is M. The minimum and maximum distances of the planet from the sun are R1 and R2, respectively.

Using Kepler's 3rd law and Newton's law of universal gravitation, find the period of revolution P of the planet as it moves around the sun. Assume that the mass of the planet is much smaller than the mass of the sun.

Use G for the gravitational constant.

Express the period in terms of G, M, R1, and R2.

Thanks for any help!!
