if a is the subset of b and b is the subset of c .then prove that a is the subset of c

If A and B are sets such that each element of A is an element of B, then we say that A is a subset of B and write A B. ..

Find the number of 3 element subsets that can be formed from the set {a, b, c, d, e, f, g, h} . => 6 or 56 or 336 or 1..

Scent: Many of the flowers emit sweet smell to attract insects. It is an excellent adaptation especially in nocturnal flowers. Because of scent even in the absence of light, insects can reach the flowers. e.g., Cestrum (night queen). Bees and butterflies are attracted by sweet smell. But the inf..

Every set A is a subset of universal set U since, by definition all elements of A belong to U. Also the null set f A..

The potential energy decreases linearly with decrease in height. On the other hand, the kinetic energy increases with decrease in height. The horizontal line represents the total mechanical energy. Let us now consider a body sliding down a smooth inclined plane. Consider a smooth inclined plane of ..

The vertices of ΔABC are: A(0, 0), B(1, 1), C(2, 0). Prove that ΔABC is isosceles...

. Thus, if 'q' is the amount of heat absorbed or evolved by the system then: q (at constant volume) = D E q (at constant pressure) = ..

From this experiment, we can conclude that when the center of gravity is nearer the base of support as in figure (b) above, the body is in the stable equilibrium. In figure (a) in previous experiment and figure (a) above, the body is said to be in unstable equilibrium. The body is said t..

C 4 plants like maize, sugarcane; pearl millet, etc. have evolved a wonderful mechanism to avoid photorespiration, which is considered a wasteful process. In these plants three or 2 types of photosynthetic cells namely mesophyll cells and bundle sheath cells. The bundle sheath cells are..
