How do gamma rays work? Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells. Why are gamma […]
What is a experiment simple definition?
What is a experiment simple definition? An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Uses of experiments vary considerably between the natural and human sciences. What is basic experiment? A simple experiment is […]
How do you do apparent weight?
How do you do apparent weight? The apparent weight of an accelerating object is the vector sum of its real weight and the negative of all the forces that produce the object’s acceleration a = dv/dt. wapparent = wreal – ma. How do you use apparent in a sentence? Certain problems were apparent from the […]

What is the electric flux through a cube of 1 cm?
What is the electric flux through a cube of 1 cm? Therefore, the net charge enclosed within the cube is zero. Therefore, electric flux is zero. What are the three basic properties of the electric charge? In this section, we will learn about three such properties of point charges; the additivity of electric charge, the […]

What are 2 parts of transverse wave?
What will happen if magnetic field reverses?
What will happen if magnetic field reverses? During an excursion or a reversal, the magnetic field is considerably weakened and allows many more cosmic rays to reach the surface of the planet. These energetic particles from space can be damaging to life on Earth if too many reach the surface. Is the magnetic field stable? […]
