Write the radian measure of an angle with 9 clockwise rotations in standard position. => 18 π or - 18 π or - 9 π or 9 π..

Angles that are formed by counter clockwise (anti clockwise) rotation, such as the one shown in fig (ii) are said to be positive or to have positive measure. Angles that are formed by a clockwise rotation, like the one in fig(iii) are said to be negative or to have ne..

Which of the following statement(s) is/are true ? I. Mode is the measure of central tendency used in exploratory data analysis (EDA). II. Extremely low data value in the data set can be considered as an outlier. III. Percentiles are the same as percentages. => II only or I, II a..

In this section, Let us understand how the position changes with time when the velocity changes uniformly with time. Let us consider a particle moving with uniform acceleration 'a' and having an initial velocity v (0) at t = 0. For the sake of convenience, both distance and time are ..

Measurement of Length - Different types of lengths are measured by using different types of instruments. Lengths like the length of cloth or length of a line can be measured by using measuring tape, a metre scale or a foot rule. But these instruments cannot b..

Molecules having two equal and opposite charges separated by certain distance are said to possess an electric dipole. In the case of such polar molecules, the centre of negative charge does not coincide with the centre of positive charge. The extent of polarity in such covalent mole..

Write the degree measure of an angle with 1 6 clockwise revolution in standard position. => 60 o or - 60 o or 6 o or - 6 o..

Two boys are standing on either side of a pole that is h = 160 m long. Their angles of elevation of the top of the pole measures 30°20′ and 45°30′. Find the distance between the two boys. (The position of the boys and the foot of the pole are collinear.) => 1..
