Which of the following statements is true? a. prior to the kepler mission, most of the extrasolar planets that had been discovered had jupiter-like masses but orbited very close to their parent stars. b. our technology has only recently become sensitive enough to detect planets with lower masses or greater distances from their parent stars. c. both d. neither

For the given question, out of the 4 options provided, the correct one is

option C. Both

Explanation:

Both the given option A and option B are correct

Earlier, prior to Kepler's most of the planets that were discovered then are those with larger masses with the help of transit technique.

The planets with lower or lighter masses were not detectable due to the reason that at that time we did not have latest technologies and methods as of today to detect planets with lower masses which is now possible by making use of spectroscopic changes in emission from the stars by Doppler shift.

its A

Explanation:

i got this right and i'm big brain

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
