' B ' is the only choice on the list that tells you a definite place, where you could go to pick up the object or meet somebody.
But in order to use it, you also have to know where the origin of coordinates is ... the point (0, 0) .
__________
No, I'm wrong about that. You have to know where SOME other point is, but that doesn't have to be (0, 0).
Answer:
Explanation:
As we know that
PV = nRT
here we have
so we have
T = 290 K
now we have
now the mass of gas is given as
now density of gas when its volume is increased to 3.3 L
so we will have
The object becomes neutralized in charge. The positive charge in the field neutralizes the negative charge in the object.
Tetrahedron is a geometrical figure or solid that is formed in similar manner as a pyramid. The faces of the formed pyramid are triangles. Also is the base.
By the statement above, it can be deduced that the figure has four sides. The number of ways in which the sides can be colored by any of the three (3) colors is,
3 x 3 x 3 x 3 = 81
Since the sides can still have the same colors, we deduct this value by 3 in order to eliminate the uniform colors of the four sides.
= 81 - 3 = 78
Also, we can eliminate the concern on only two colors can mix,
= 3 x 2 = 6
Subtracting,
78 - 6 = 72
Hence, the answer is 72.
