Standing pieces:
2(9x6)+4(9x3) = 108+108 = 216
“L” horizontal pieces:
cut it to 3 squares of 3x3 each
2x3(3x3) = 54
total surface area = 216+54 = 270cm^2

You have the cards numbered 1-10 in front of you.Each time you select a card,it is returned.What is the probability of selecting

Tatiana [17]

Answer:

$Both \: the \: moon \: and \: earth \: are \: in \: \\ the \: shape \: of \: spheres. \\ Surface\: area \: of \: a \: sphere \: of \: radius \: 'r' \\$

Let d1 be the diameter of the moon and d2 and be the diameter of the earth.Let r1 be the radius of the moon and r2 be the radius of the earth.

$given \: d1 = \frac{1}{4}d2 \\ = > 2r1 = \frac{1}{4} ×2r2 \\ =>r1 = \frac{1}{4}×r2 \\ Now, \: ratio \: of \: \: their \: surface \: areas \: is: \\ = s1: s2 \\ = r {1}^{2}: r {2}^{2} \\ = {1}^{2 } : {4}^{2 } \\ =1:16$

hope it helps you

In the theory of relativity, the mass of a particle with velocity v ism = m01 − v2/c2,where m0 is the mass of the particle at re

ahrayia [7]

Answer:

as v tends to c( speed of light), the mass of the particle moves towards an infinite value

Step-by-step explanation:

The concept applied here is the theory of relativity.

what the theory entails is the measurements of events i.e things that happen, where and when they happen and to what large extend are events seperated in space and time. Albert Einstein was the first to published his findings on the theory of relativity.
