What are the types of radio stations? Different types of radio Conventional FM: As previously mentioned, conventional FM is a popular technology in analog radio. MPT1327: Perhaps the most widely used analog trunking technology today is called MPT 1327. Tetra: As the world becomes more digital, a number of digital radio technologies have emerged. Who […]
Why is nuclear energy bad?
Why is nuclear energy bad? Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years. Is nuclear energy safe? […]
What happens when a capacitor is short circuited?
What happens when a capacitor is short circuited? A short circuit here means that there is no resistance (impedance) between the two terminals of the shorted capacitor. The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. This means you can ignore the shorted capacitor — it has no […]
What is one effect of the uneven heating of Earth caused by the sun?
What is one effect of the uneven heating of Earth caused by the sun? Usually when we talk about uneven heating of the Earth’s surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and […]
Why does temperature increase with mass?
Why does temperature increase with mass? If density increases ,volume decreases and if density decreases , volume increases. So density*volume=mass remains same as before. Gravitational pressure increases the more mass there is, and that pressure creates energy that increases temperature. Why does it take longer to heat up a larger volume of water? Simple: you’re […]

What can happen to your bones if they lose calcium?
What can happen to your bones if they lose calcium? Aging and Bone Loss As you age, your body may reabsorb calcium and phosphate from your bones instead of keeping these minerals in your bones. This makes your bones weaker. When this process reaches a certain stage, it is called osteoporosis. Is calcium more concentrated […]
Is nitrogen harmful to humans?
Is nitrogen harmful to humans? High concentrations of nitrogen gas can be particularly harmful to human health. Nitrogen can displace oxygen from ambient air within an enclosed space leading to a dangerous build-up of the inert gas. Is nitrogen safe to consume? Liquid nitrogen, although non-toxic, can cause severe damage to skin and internal organs […]
Is 50 hp enough for a motorcycle?
How are the two variables associated with each other?
How are the two variables associated with each other? Association between two variables means the values of one variable relate in some way to the values of the other. Association is usually measured by correlation for two continuous variables and by cross tabulation and a Chi-square test for two categorical variables. What can be used […]
