Why is it called polonium-210?
Why is it called polonium-210? What is Po-210? Share on Pinterest Polonium-210 is highly radioactive substance and a lethal poison. Polonium is a radioactive chemical element (atomic number 84) that was discovered in 1898 by Marie Curie, who named the element after her country, Poland. What is PO-210 used for? Po-210 is used in some […]
Why is energy directly proportional to frequency?
Why is energy directly proportional to frequency? Because the velocity is constant, any increase in frequency results in a subsequent decrease in wavelength. Therefore, wavelength and frequency are inversely proportional. Photon energy is directly proportional to photon frequency. What frequency has the most energy? Gamma rays Does energy have a frequency? Wave frequency is related […]
What is the declination of the sun today?
What is the declination of the sun today?

Do like charges repel or attract?
Do like charges repel or attract? Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between […]
Why does America still use imperial?
Why does America still use imperial? Because the Imperial System (IS) of measurements was in place at this time, the machinery used in these factories was developed to size in IS units; all of the workers were trained to deal with IS units; and many products were made to feature IS units. How cold is […]
How energy is transformed in motor?
How energy is transformed in motor? A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field. What is the role of split ring in […]
Why is acceleration due to gravity more at poles?
Why is acceleration due to gravity more at poles? It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth’s oblateness. The measured value is larger because the earth’s […]
Can an umbrella kill you?
Can an umbrella kill you? Beach umbrellas have caused at least one death. In 2016, Lottie Michelle Belk was killed when an errant parasol pierced her torso while she was on holiday in Virginia Beach. “As you know, beach umbrellas provide beachgoers the benefits of shade on hot and sunny days at the shore,” the […]
