What is the formula for resistance? Resistance has units of ohms (Ω), related to volts and amperes by 1 Ω = 1 V/A. There is a voltage or IR drop across a resistor, caused by the current flowing through it, given by V = IR. How do you convert a resistor from 12v to 19v? […]
How can you tell if you see ultraviolet light?
How can you tell if you see ultraviolet light? By definition, ultraviolet light is ‘beyond violet light’ and the visible spectrum that can be detected by the human eye. It cannot, therefore, be seen directly. Detectors that are sensitive to UV convert it into a form that we can see. In this scenario, however, UV […]
Can a fire blanket be wrapped around a person?
Is it safe to ground yourself?
Is it safe to ground yourself? No. If the outlet were miswired or a device shorted out and pulled the ground voltage at the outlet up, you could be electrocuted. If you accidentally touched a live wire, you could be electrocuted through the connection to ground you made to yourself. This would be an absurdly […]
Is Fiber Optics safer than 5G?
Is Fiber Optics safer than 5G? Wired fiber-to-the-premises (FTTP) is the speediest, healthiest, most secure, reliable, and energy-efficient way to stream Internet and video data. Wired networks are always faster and safer than wireless 5G. Is 5G faster than Fibre? In short, 5G can deliver faster speeds, more quickly than fibre. Will fiber optics become […]
Is a snow hurricane possible?
Is a snow hurricane possible? Since that time, there has been only one other confirmed snowfall event as a result of a tropical cyclone while still considered to be tropical, which was caused by Hurricane Ginny in 1963, generating accumulations of 13 in (33 cm) in Maine. Has there ever been an ice hurricane? In […]
What can be found in the thermosphere?
What can be found in the thermosphere? In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air. Much of the X-ray and UV radiation from the Sun is absorbed in the thermosphere. When the Sun is very active and emitting more high energy radiation, the thermosphere […]
Why is there no screaming on roller coasters?
Why is there no screaming on roller coasters? No screaming on roller coasters? Not exactly. As California counties continue reopening business sectors in the wake of falling case numbers, the state’s Attractions and Parks Association recommended that park officials “mitigate the effects of shouting” on rides. Can you scream in California? The bad news is […]
What will happen if tectonic plates continue to move?
What will happen if tectonic plates continue to move? One big problem with plate tectonics stopping is that plate motion is the mechanism by which Earth is cooling down and getting rid of its internal heat. If the plates stopped moving, the planet would have to find a new and efficient means to blow off […]
What are the negative social impacts?
What are the negative social impacts? These negative social impacts include; social change; changing values; increased crime and gambling; changes in moral behaviour; changes in family structure and roles; problems with the tourist-host relationship and the destruction of heritage. What are the negative effects of tourism and hospitality in the economy? Increasing demand for basic […]
