What is the powerful MAGNET in the Universe?

Posted by Gautam Jayant 8 years, 3 months ago

1 answers

Amar Kumar 8 years, 3 months ago

Magnetars are an unusual and very exotic form of neutron star. Like all of these strange objects they are tiny and extraordinarily dense — a teaspoon of neutron star material would have a mass of about a billion tonnes — but they also have extremely powerful magnetic fields. Magnetar surfaces release vast quantities of gamma rays when they undergo a sudden adjustment known as a starquake as a result of the huge stresses in their crusts.

What is dimensional analysis

Posted by Mohit Singh 8 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Sahdev Sharma 8 years, 3 months ago

Dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric charge) and units of measure (such as miles vs. kilometers, or pounds vs. kilograms vs. grams) and tracking these dimensions as calculations or comparisons are performed.
