When the ice age ended, the glaciers slowly retreated until they reached their current extent limited to the polar regions and alpine mountain climates. The land covered by ice had also been depressed by the weight of the massive glaciers and consequently began to rebound in the centuries following the retreat of the ice sheets. These once frozen lands also turned into large boreal forests with rich ecosystems.

prohojiy [21]

Answer:

Slow slip, silent

Explanation:

Slow slip refers to earthquakes that occur ~25 miles below the earth's surface, which are called Silent quakes. Detecting the onset of such events can provide a warning that a large earthquake is imminent

Anne releases a stone from a height of 2 meters. She measures the kinetic energy of the stone at 9.8 joules at the exact point i

nlexa [21]

Eₖ = √1/2 mv²

Eₖ/v² = 1/2 m

2Eₖ/v² = m

mgh = 1/2 mv²

gh = 1/2 v²

2gh = v²

v = √2gh

= √2 × 10 N/kg × 2 m

= 6.324 ms⁻¹

m = 9.8/(6424)²

= 9.8/39.993

= 0.245 g

I am not sure if it's correct.

i transposed for m in the first equation then to find the velocity I combined the potential and kinetic energy equation. there was no mass because velocity doesn't depend on the mass

Then I used earth's gravitational field strength (g) 10 N/kg and the 2 m was the height provided in the question

you can try working and see if you get the same
