Answer:
+1 ion
Explanation:
Alkali metals are metals that are found in Group I of the periodic table. Their electronic configuration is such that their valence shell in grounds state is always holding only one electron which they always lose when reacting with non-metals. A loss in an electron makes the atom electrically imbalanced and hence becoming a +1 ion.
Kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously. So, A.
Answer:
Explanation:
Heat capacity = mass x specific heat
heat capacity ∝ mass
∝ volume
heat capacity ∝ volume
H₁ / H₂ = V₁ / V₂
H₁ and H₂ are heat capacity corresponding to volume V₁ and V₂.
312 / 100000 = 1 / V₂
V₂ = 100000 / 312
= 320.51 cubic foot.
Answer:
Decrease
Explanation:
If you were on the Moon, which has significantly less mass than the Earth, your weight would: decrease
The point that seemed to be giving me a complicated time was being able to distinguish the difference and meaning of weight and mass and being able to apply that to a problem. I kept mixing up the definitions. For example in homework 3.1, one question asked:
If you were on the moon, which has significantly less mass than the earth, your mass would:
a. increase
b. decrease
c. stay the same
d. become zero
The definition of mass is the amount of matter in an object. The definition of weight is the amount or unit of force. For me, I just had to remember that when it asked about weight, it wasn’t referring how heavy an object is. After I was able to recognize that when it came to weight, questions became easier.
The final and correct answer was decreasing. The answer is because the Moon’s mass is less. This means the gravitational force is less on your body, therefore, your mass is going to be lighter
Because when a white light goes through a clear object like the glass pyrimide it divides into the different color lights the different color lights travel in different speeds like the red light traveles faster that the purple light thats why on a rainbow the red is on the top and purple is on the bottom
