If you drop a steel ball weigh 4 kg from a height of 60 m will it fall more rapidly through water at 25°F or water at 45°F or will it make no difference

It will make no difference.

Explanation: For an object to float or sink in a fluid, there is a force called buoyancy force acting on it.

Buoyancy force is an upward force experienced by the object due to the fluid. Its magnitude is calculated by the formula:

where:

is density of the fluid

V is volume of the object

g is gravity

The steel ball is free falling, so, there is gravitational force acting on it.

Since it is falling into the water as well, there will be buoyant force acting against the gravitational one. But none of the forces is dependent on water temperature so that variable won't change the falling.

So, temperature will make no difference.

explanation:

-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
