Answer:
1. 2. chemicals in the injected fluids can get into groundwater that is used for drinking water;
B). Hydraulic fracturing allows geologists to capture natural gas stored in the pore spaces of shale.
Explanation:
- Fracking is a huge amount of the water that must be transported to sight at a significant environmental cost and occurrence of the minor tremors and is environmentally and potentially dangerous chemicals of they escape during the drilling and pollute the groundwater.
- And the hydraulic fracking is drilling methods used to extract the natural oil and gas from deep inside the earth and is used to study the geology of the earth.
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

Answer:
33300J
Explanation:
Given parameters:
Mass of ice = 100g = 0.1kg
Initial Temperature of water = 0°C
Final temperature = 0°C
Unknown:
Amount of energy = ?
Solution:
The amount of energy is given by;
Amount of energy = mL
m is the mass
L is the latent heat of fusion = 3.33 x 10⁵ J/kg
Amount of energy = 0.1kg x 3.33 x 10⁵J/kg
Amount of energy = 33300J
