ONLY ANSWER IF YOU ARE POSITIVE PLEASE science question
A star is moving towards Earth. An astronomer plans to measure the distance of the star from Earth by observing the red shift in its spectrum. Which of these statements best explains why the astronomer's method of measuring the star distance is inappropriate? (1 point)
The spectral shift of moving stars cannot be observed.
A red shift can be observed when the star moves away from Earth.
Common instruments cannot measure the red shift accurately.
Rate of motion of stars cannot be matched with the rate of measuring distances.
Thank you! I give brainliest!

in physics zero. in muscle fatigue could be high

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this

force tends to be low and long diustance masses are high
