Starting with the top 3 digit number, the first digit increases by 2 as you descend,from 1 to 11. The middle digit decreases by 1 each time,and the right hand digit alternates between 5 and 3

Probability is Number of favourable outcomes by total outcomes

Total comes = 2 (Divisible or not)

Favourable = 1 (Divisible)

Hence, probability = 1/2.

World Population day is an annual event, observed on July 11 every year, which seeks to raise awareness of global population issues. 

Electrical Pressure is also called as Voltage. Voltage is measured in Volts.

Volt : A unit of electrical pressure or Voltage is called Volt.

One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance.

Voltage is also referred to as Electromotive Force or Electrical Potential or Electrical Pressure.

The Kerala government has implemented Green Protocol for making weddings more naturally in the state. The purpose of the initiative is to reduce the use of plastic in daily life. With the implementation of the protocol, use of plastic and other non-degradable articles including disposable glasses and plates and thermocol decorations will be discouraged at marriage functions. Inspections will be held at marriage halls, convention centres and hotels and other venues of the wedding ceremony in this regard and action would be taken if the protocol is violated. The state nodal agency for sanitation ‘Suchitwa Mission’ has already launched the initiative in Kannur, Ernakulam, Kollam and Alappuzha on a pilot basis. As per officials, the protocol would be implemented in the rest of the districts soon.

$$\begin{gathered} Given 3.2% of 500 × 2. 4% of ? = 312 \\ Then, \\ 3.2 x 500100 x 2.4 x ?100 = 312 \\ 16 x 2.4x?100 = 312 \\ 9.6 x ?25 = 312 \\ 9.6 x ? = 7800 \\ ? = 78009.6 \\ ? = 812.5 \end{gathered}$$

A Slip ring is a ring in a dynamo or electric motor which is attached to and rotates with the shaft, passing an electric current to a circuit via a fixed brush pressing against it.

Slip rings are usually made of Phosphor Bronze.

Slip ring motors usually have a 'phase-wound' rotor. This type of rotor has a 3-phase, double-layer, distributed winding consisting of coils used in alternators. The rotor core is made up of steel laminations which have slots to accommodate formed 3-single phase windings.
