Answer:
Amount of heat energy released by light bulb = 25 joules
Explanation:
Given:
Energy receive by light bulb = 100 Joules
Energy released by light bulb as light energy = 75 Joules
Find:
Amount of heat energy released by light bulb
Computation:
We know that, energy is neither be created nor destroys
So,
Using Law of conservation of energy
Energy receive by light bulb = Energy released by light bulb as light energy + Amount of heat energy released by light bulb
100 = 75 + Amount of heat energy released by light bulb
Amount of heat energy released by light bulb = 100 - 75
Amount of heat energy released by light bulb = 25 joules
The answer is true
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light.The wavelength decreases as the light enters the medium and the light wave changes direction.
I believe the answer is B. a million or more.
The definition of a gem is "a precious stone, cut and polished for jewelry. They are all minerals. Some highly desirable gemstones may not be suitable for jewelry, yet be very collectible, like sphene. Others, like those in the corundum family, are prized for color and hardness, like emeralds and diamonds. Further, some common minerals, when polished, make beautiful pieces. With all that said, i woukd go with rarer.
Answer:
1,816 L
Explanation:
Molar concentration or molarity is a way to express the concentration of a chemical in terms of moles of substances per liter of solution.
To obtain the liters of this solution you must convert moles/L to g/L with formula weight (FW), thus:
0,1107 mol of KCl / L × (74,6 g / mol) = 8,258 g of KCl / L.
It means that in one liter you have 8,258 g of KCl. Thus, 15,00 g of KCl are contained in:
15,00 g × (1 L / 8,258 g) = 1,816 L
I hope it helps!
