Which of the following statements regarding the big bang theory are true? choose one or more: a. all stars will end their lives explosively as supernovae. b. meteors were responsible for the extinction of the dinosaurs. c. the universe is considerably older than earth. d. all matter in the universe was once confined to a single point. e. earth formed through a series of violent collisions. f. there is no way of knowing how old the universe might be. g. earth is much older than the rest of the universe. h. earth and the universe formed at about the same time.

Step by step solution :

(A) All stars will end their lives explosively as supernovae. False

Supernova is a star that undergo a sudden increase in brightness across the electromagnetic spectrum. It occurs when a super giant star collapses suddenly.

The stars having high mass ended their lives with supernovae but low masses stars star, the core part of the star is left. So, no all stars end their lives explosively as supernovae.

(B) Meteors were responsible for the extinction of the dinosaurs. True

Dinosaurs become extinct due to the impact of giant meteorite. This meteorite blocks sunlight for a longer time. As a result, plant eaters died and then meat eaters died.

So, this statement is correct.

(C) The Universe is considerably older than Earth. True

The universe is approximately 13.8 billion years old. So, we can say the universe is older than earth.

(D)  All matter in the Universe was once confined to a single point. True

According to big bang theory the whole matter of universe is confined at a single point.

(E) Earth formed through a series of violent collisions. False

(F) There is no way of knowing how old the Universe might be. False

There can be two way to know the age of universe :

(1) By glancing the oldest stars.

(2) By measuring the rate at which the universe is expanding.

(G) Earth is much older than the rest of the Universe. False

(H) Earth and the Universe formed at about the same time. False

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
