Athermos bottle reduces energy loss due to radiation reduces energy loss due to conduction reduces energy loss due to convection all of the above

all of the above

Option (d) is the correct answer.

Explanation:

A thermos bottle is defined as a bottle which has vacuum between inner and outer wall so that the material will keep warm.

Therefore, in a thermos bottle there will be reduction in energy loss due to radiation, conduction and convection.

Thus, we can conclude that a thermos bottle is all of the above.

a is the best answer your welcome

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
