What is the relationship between metallic and ionization energy? Metallic character refers to the level of reactivity of a metal. The metallic character increases as you go down a group. Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to […]

Which describes the first law of thermodynamics? The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. “So, it’s a restatement of conservation of energy.” What is the second […]

What speed do radio waves travel in a vacuum? Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. How far can […]

How do you graph an inequality with two variables? To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality. If given a strict inequality, use a dashed line for the boundary. If given an inclusive inequality, use a solid line. […]

Can I self refer to an endocrinologist? When to See an Endocrinologist A primary care provider will determine if you need to see an endocrinologist and can write you a referral. The PCP may be able to diagnose and treat your condition themselves, without referring you to specialized care. What tests does an endocrinologist do? […]

Is it safe to drink deuterium? The breakthrough involves the use of heavy water as a chemical tracer. Made by swapping water’s hydrogen atoms with their heavier relative, deuterium, heavy water looks and tastes like regular water and in small doses (no more than five tablespoons for humans) is safe to drink. How much of […]

Why is argon the cheapest noble gas? Because argon is so stable and is a poor heat conductor it is used as a shield gas in arc welding. Argon is used when other non reactive elements become reactive. Argon is the cheapest of all the noble gas. Argon is priced at a measly half a […]

Which is brighter bulbs in series or parallel? Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit. Unscrewing one bulb has no effect on the other bulb. Which bulb will glow brighter in parallel? Key Points: In […]

How do you write amplitude? The Amplitude is the height from the center line to the peak (or to the trough)….Now we can see: amplitude is A = 3. period is 2π/100 = 0.02 π phase shift is C = 0.01 (to the left) vertical shift is D = 0. What happens if you increase […]

How much of Florida was underwater? As glaciers of ice in the north expanded and melted, the Florida peninsula emerged and submerged. When the sea level was lowest, the land area of Florida was much larger than it is now. The sea level was as much as 100 feet lower than at present. Florida s […]
