Concept explainers
A heavy steel ball is suspended by a thin wire. The ball is hit from the side with a hammer but hardly moves. Describe what you think would happen if this identical experiment were carried out on the moon.
Interpretation:
The explanation corresponding to the given situation is to be stated.
Concept introduction:
Mass is the measurement of matter that is present in an object. Weight measures the gravitational force acting on an object. Mass is one of the factors on which gravitational force depends. On changing the gravitational force, weight of a substance also changes, but mass is independent of gravity. Thus, it is clear that with the large amount of matter, an object would have higher value of weight and mass.
Answer to Problem 1.1E
On the moon, the weight of a ball is low due to which it covers more distance on the moon than on the Earth.
Explanation of Solution
It is given that if a ball is hit with a hammer, it moves hardly on the Earth.
The gravitational force on the moon is one sixth the gravitational force on the Earth due to which gravitational force on matter will be more on the Earth than that on the moon. Gravity pulls the ball towards the ground and the opposing air resistance slows it down. The gravitational force and the air resistance on the moon is less as compared to that on the Earth due to which the ball can move further on the moon than on the Earth.
On the moon, the weight of ball is low due to which it covers more distance on the moon than on the Earth.

For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
