What are five ways in which people can explore and study space without physically going there?

1) use of telescopes

2) analysis of cosmic radiations

3) using doppler shift for stars.

4) analysis of background radio waves

5) use of geometry for predicting travel path of space materials.

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.
