Complete the sentences to describe the postulates of Einstein’s special theory of relativity.

Einstein’s special theory of relativity has two postulates.

The first postulate states that the laws of physics are the in all uniformly moving reference frames.

The second postulate states that the speed of light in a vacuum has the same value for all , regardless of the state of of the observer or the source of light.

'SAME'
'OBSERVERS'
'MOTION'

Explanation:

The two postulates of Einstein’s special theory of relativity are as follows :

1. The first postulate states that the laws of physics are the same in all uniformly moving reference frames.

2. The second postulate states that the speed of light in a vacuum has the same value for all observers, regardless of the state of motion the observer or the source of light.

These are two postulates of Einstein’s special theory of relativity.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
