Question

Which of the preceding statements is/are true?A) Helioseismology is the study of the differential rotation and magnetic field of the Sun. B) A filtergram is used to study layers below the photosphere. C) The chromosphere of the Sun has a higher temperature than the photosphere.

Answer 1

Answer:

A and C

Explanation:

Helioseismology is a branch of science that makes use of  differential rotation and magnetic field to study he structure of the sun.

A filtergram represents the photo of the surface of the sun that is made using high energy particles being accelerated by the sun's magnetic field. Hence, it can only be used to study the surface and not the layers below the photosphere.

The chromosphere of the sun has a temperature between 6,000 °C to about 20,000°C while the photosphere has a temperature between 4,230 and 5,730 °C. Hence, the chromosphere has a higher temperature.

The only true options are A and C.
