Answer:
20 kg
Explanation:
remember the equation f=ma.
100 N=force
5 m/s2= acceleration
so you need to divide force by acceleration: 100 N/ 5 m/s2= 20 kg, to get the mass.
Answer:
55000000 years
Explanation:
Rate of North American Plate moving (Velocity) = 20 mm/yr
Degrees New York has to move = 10° west
New York's longitude = 110 km/°
Distance of New York = 110×10 = 1100 km
= 1100×10⁶ mm
![\text {Time taken by the continental plate}=\frac {\text {Distance of New York}}{\text {Rate of North American Plate moving (Velocity)}}\\\Rightarrow \text {Time taken by the continental plate}=\frac{1100\times 10^6}{20}\\\Rightarrow \text {Time taken by the continental plate}=55\times 10^6\ years](https://tex.z-dn.net/?f=%5Ctext%20%7BTime%20taken%20by%20the%20continental%20plate%7D%3D%5Cfrac%20%7B%5Ctext%20%7BDistance%20of%20New%20York%7D%7D%7B%5Ctext%20%7BRate%20of%20North%20American%20Plate%20moving%20%28Velocity%29%7D%7D%5C%5C%5CRightarrow%20%5Ctext%20%7BTime%20taken%20by%20the%20continental%20plate%7D%3D%5Cfrac%7B1100%5Ctimes%2010%5E6%7D%7B20%7D%5C%5C%5CRightarrow%20%5Ctext%20%7BTime%20taken%20by%20the%20continental%20plate%7D%3D55%5Ctimes%2010%5E6%5C%20years)
∴ Time taken by New York to move 10° west is 55000000 years
Methods of extraction include: extract by electrolysis, extract by reaction with carbon or carbon monoxide, and extracted by various chemical reactions.

Answer:
even if it all could be used, it wouldn't be enough
Explanation:
The land area of the US is about 5.45% of the world's area, so the amount of released heat over the area of the US is on the order of 2.4 Tw. Current technology for converting geothermal energy to electricity is about 12% efficient, so the available energy might amount to 0.29 Tw if it could all be captured.
Energy consumption in the US in 2019 was on the order of 0.46 Tw. This suggests that even if <em>all</em> of the thermal energy radiated by the Earth from the US could be turned to useful forms of energy, it would meet only about 60% of the US need for energy.
