A 12.9 kg pelican, with a 1.51 kg fish in its mouth, is flying 14.94 m/s at a height of 114 m when the fish wiggles free and fall back toward the ocean. How fast is the fish moving when it hits the water

v =  49.6 m/s

Explanation:

The vertical component of the final speed can be found by using 3rd equation of motion:

where,

g = acceleration due to gravity = 9.81 m/s²

h = height = 114 m

Voy = vetical component of initial velocity = 0 m/s (since the pelican is flying horizontally)

Vy = Vertical component of final velocity = ?

Therefore,

Now, the horizontal component of the velocity is assumed to be the same because of negligible frictional force. Therefore,

Vx = 14.94 m/s

Thus the final speed will be given as:

v =  49.6 m/s

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

-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
