Neglecting any thermal or friction effects, indicate the relative magnitudes of the following forms of energy at different locations of the mass/spring during the vertical oscillation. Use the terms "maximum" "minimum" "zero" "something else" or "I don’t know or care" ("Idkoc") for each of these three types of energy: kinetic energy (KE), spring potential energy (SPE), and gravitational potential energy (GPE). 1. Exactly at the instant it is at the bottom, x2, what is the best description about its KE?

2. Exactly at the instant it is at the bottom, x2, what is the best description about its SPE?

3. Exactly at the instant it is at the bottom, x2, what is the best description about its GPE?

4. Now let's consider when it is exactly at the instant when it reaches its highest point, x1. What is the best description about its KE?

5. Consider when it is exactly at the instant when it reaches its highest point, x1. What is the best description about its SPE?

6. A spring of spring constant k = 12.5 N/m is hung vertically. A 0.400 kg mass is then suspended from the spring and finally comes to rest and remains stationary. What distance is the spring stretched due to the weight of the 0.400 kg mass when it is hanging motionless? Give your answers in meters - example: 1.23 m

-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

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
