Calculate the energy that 1.5 kg of mass contains

Vsevolod [243]

Answer:

$4.5(10)^8$ joules

Explanation:

Mass–energy equivalence is the principle that says that anything that has mass has an equivalent amount of energy. Converse is also true.

The relation between energy and mass is given by $E=mc^2$

Here, E denotes energy, m denotes mass and c denotes speed of light

Mass $(m)=1.5\,\,kg$

Speed of light (c) = 3 × $10^8$ m/s

Therefore,

$E=1.5(3)(10)^8=4.5(10)^8$ joules.

The S.I. unit of energy is joules which is equal to $1\,\,kg\,\,m^2/s^2$

How was the speed of light determined

goblinko [34]

Presently, the speed of light in a vacuum is defined to be exactly 299,792,458 m/s (approximately 186,282 miles per second). . An early experiment to measure the speed of light was conducted by Ole Romer, a Danish physicist, in 1676. Using a telescope, Ole observed the motions of Jupiter and one of its moons, Io
