Answer: 1.Sulfuric acid is a catalyst
2. Vanadium(v) oxide is a catalyst
As the earth is in the form of a sphere, the angle of incidence of the sun's rays at the earth's surface increases from the equator towards the poles and therefore the amount of heat received on a GIVEN AREA diminishes in the same direction. Temperature is therefore normally hottest near the equator and coolest near the poles.
Answer:

The correct option is A.
Speed is the ratio of the distance an object moves from a reference point to the amount of time it takes to travel the distance.
For a fixed distance, if the time required to travel the distance is less than the speed is high. However, if time to cover the same amount of distance is more than the speed is low. Therefore, the measurement of speed distance and time has an inverse relationship.
