Concept explainers
(a)
Interpretation:
Whether the distance covered on throwing a bowling ball change when done on Earth and then on the moon is to be stated. The reason for the same is to be explained.
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.
(b)
Interpretation:
Whether the distance rolled by a bowling ball on a flat, smooth surface change when done on Earth and then on the moon is to be stated. The reason for the same is to be explained.

- Marie Curie was born in Poland but studied and carried out her research in Paris. In 1903, she shared the Nobel Prize in Physics with H. Becquerel and her husband Pierre for their discovery of radioactivity. (In 1911 she received the Nobel Prize in Chemistry for the discovery of two new chemical elements, radium and polonium, the latter named for her homeland, Poland.) They and others observed that a radioactive substance could emit three types of radiation: alpha (), beta (), and gamma (). If the radiation from a radioactive source is passed between electrically charged plates, some particles are attached to the positive plate, some to the negative plate, and others feel no attraction. Which particles are positively charged, which are negatively charged, and which have no charge? Of the two charged particles, which has the most mass? Radioactivity. Alpha (), beta I(), and gamma () rays from a radioactive element are separated by passing them between electrically charged plates.arrow_forwardConsider helium and argon gases. a.Why do helium-filled balloons rise? Justify your answer using a quantified property of helium. b.You have probably seen how people can breathe in helium and the property you discussed in part (a) causes their voices to come out much higher than normal when they talk.
