In 1980 the average yearly ice loss found was -.05 whereas in the year of 2010 the average yearly ice loss found was -14. it is two hundred and eighty times greater than the average yearly ice loss in the year 1980.
They would use the Scientific method
Answer:
The correct option is;
The star is moving toward Earth.
Explanation:
The shifting of the wavelength of light wave toward the blue end of the electromagnetic spectrum is termed blue shift.
A blue-shift of an electromagnetic wave corresponds to the wavelength decrease of the wave, which is equivalent increase in energy, resulting in an increase in the observed frequency of the wave.
Astronomers make use of the shifting of the wavelength of a wave to understand the relative motion of galaxies.
The wavelength of an approaching electromagnetic ave shifts towards the blue end of the electromagnetic spectrum because the wavelength is shorter.
The opposite of phenomenon is red-shift.
The weight of the cooler is (mg). That's (26)(9.8) = 254.8 Newtons.
Its gravitational potential energy while it's up in the top row is (mgh). That's (254.8)(17.5) = 4,459 Joules.
That's how much work it took to get the cooler up to the top row, and that's the energy it gives up when it moves back down to the bench.
In order to bring it down . . .
-- Gravity does 4,459 joules of work on the cooler.
-- The team assistant does NEGATIVE 4,459 joules of work on it.
