Question Discussion & Solution

Concept:

Indian Space Research Organisation (ISRO):

• It is the premier space agency of the government of India.
• Its vision is to harness space technology for national development while pursuing space science research and planetary exploration.
• The space research activities were initiated in India under Dr. Vikram Sarabhai, the founding father of the Indian space program, during the 1960s.
• ISRO established: 15 August 1969
• Headquarters: Bengaluru

​Explanation:

Vikram Sarabhai:

• Vikram Sarabhai was an Indian Physicist.
• He Initiated Space Research.
• He is also known as the 'Father of the Indian space program'.
• Vikram Sarabhai also researched cosmic Rays under Dr. C.V. Raman, a noble prize winner.

Thus, the Indian Space Research Center was formed by Vikram Sarabhai.

Least possible diagram is:

I. Some car are Maruti. → True

II. No Ciaz is a Maruti. → False

Concept:

• Electric current is the rate of flow electric charge or free Electrons in a definite direction through any section of wire. Its SI unit is ampere(A).
• The direction of the conventional current corresponds to the direction of positive charge which is from higher potential(positive) to lower potential(negative).

I = Q / t

I is current, Q is charge, t is time

Explanation:

Q = I t

So Charge is the product of current and time.

Unit of current is Ampere, and unit of time is an hour. 

So, Amount of charge or Quantity of electricity is Ampere-hour
