Cell phones use RF waves from nearby cell towers. RF waves fall in between FM radio waves and microwaves
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.
Yes you are right but sometimes just because a number is bigger doesnt always make it so.
We know, W = F * s
W = mg * s
Here, w = 2 J
m = 180 g = 0.180 Kg
g = 9.8 m/s
Substitute their values into the expression:
2 = 0.180*9.8 * s
1.764s = 2
s = 2 / 1.764
s = 1.13 meter
In short, Your Final Answer is 1.13 m
Hope this helps!
True.
As the length of the conductor increases, so also the resistance to the flow of current increases along the conductor.
