complete revolution

The diameter of a roller is 110 cm and its length is 150 cm. It takes 800 complete revolutions to move once over a play ground to level it. Find the area of the play ground. [Take π = 3.] => 1980 m² or 4686 m² or 3960 m² or 1320 m²..

Line segments AB ‾ and DC ‾ bisect each other at 90° as shown. What is the locus of the point A if AB ‾ makes a complete revolution with respect to E? => A straight line or A circle or An ellipse or A rectangle..

One lunar month is the time in which the moon completes one revolution around the earth. Units of all other physical quantities can be derived from the basic units and hence are called "derived units". The following table shows the list of various physical quantities, derived f..

To measure an angle we shall use two kinds of units, the degree unit and the radian unit. A degree(Sexagesimal system) is defined to be an angle formed by half-line (or a ray) rotated about its end point (1/360) of a complete revolution. Types of Angles: Acute ..

Let a ray revolve about its end point O and generates a circle of radius r. Then the radian measure of the angle formed by one complete revolution of the revolving ray \ 2 p = 360 o p = 180 o ..

. If a ray rotates about the starting initial position, in anticlockwise direction, comes back to its original position after 1 complete revolution then it has rotated through 360 o . 1 complete rotation is divided into 360 equal parts. Each part is 1 o . Each part (1 ..

. Let T represent the time taken by the body to complete one revolution. This can be divided into eight equal intervals namely and so on. A, B, C, D.... I represent the positions of the body at these instants. When the body is at A, the foot of the perpendicular will be at P o ,..

Uniform Circular Motion - The revolution of moon around the Earth and the revolution of an artificial satellite in a circular orbit round the Earth are examples of circular motion. Consider a particle moving with constant speed along the circumference of a circle of radius R in ..

Expression for Period in SHM - The angular velocity of the body moving in a circle is When the body completes one revolution, q = 360 o or 2 p radians and the time taken by the body is called the period T. In this time, the body executing SHM will have completed one os..

. Without this natural 'greenhouse effect', temperatures would be much lower than they are now, and life as known today would not be possible. Instead, thanks to greenhouse gases, the earth's average temperature is a more hospitable 60 0 F. However, problems may arise when the atmospheric concentra..
