8th grade orientation

In the 8 th grade there are 3 teams A, B, and C having 28, 35 and 37 students respectively. The mean score of Team A is 60%, of Team B is 70% and of Team C is 85%. Find the mean score of the entire 8th grade. => 75.75 or 72.75 ..

As noted earlier, the rate of reaction also depends on p, the fraction of collisions that occur with proper orientation. This factor is independent of temperature. Why proper orientation of the reactant molecule is important can be understood from the figure. fig 6.13 - Importan..

If a spacecraft is mounted with a flywheel, suggesting a scheme for orientation control, the spacecraft and the flywheel form an isolated system. So, if the system's total angular momentum is zero because neither the spacecraft nor the flywheel is turning, it must remain zero. To chang..

From Arrhenius equation, it is seen that the rate constant k of a reaction increases with temperature and therefore, the rate of reaction also increases. Why does k depend on temperature? This can be explained, to a certain extent, by collision theor..

The five d-orbitals can be divided into two groups depending upon the nature of their orientation in space. (i) The three d-orbitals (d x y , d y z , d z x ) which orient in the regions in between the coordinate axes are designated as t 2 g orbitals. (ii) The two other orbitals ..

Identify the incorrect statement. I. A rotation is a transformation that turns a figure about a fixed point. II. A rotation is an isometry. III. A rotation does not change orientation. IV. A figure has rotational symmetry, if the image after a rotation of 90° or less exactly fits on t..

. They consist of metals. 7. The Zero group consists of 'Noble gases'. 8. There are 7 horizontal rows in the periodic table. These are called the periods. 9. In a period, the number of valence shell remains the same for all elements. However, the number of electrons in the valence shell i..

Which of the following is not correct? => A reflection reverses orientation or A reflection does not reverse orientation or A reflection does not change size or A reflection is an isometry..

Leaf age, leaf angle and leaf orientation also effect the rate of photosynthesis. Mg, Fe, Cu, Mn, Cl, S and K take part in photosynthes..
