There is also the kilogram(kg), or 1000 grams
Everything in the universe that is not a star reflects light from Stars. Otherwise you can't see it.
Answer:
20.42 N/m
Explanation:
From hook's law,
F = ke ......................... Equation 1
Where F = Force applied to the spring., k = spring constant, e = extension.
Make k the subject of the equation,
k = F/e ................. Equation 2
Note: The force on the spring is equal to the weight of the mass hung on it.
F = W = mg.
k = mg/e................ Equation 3
Given: m = 250 g = 0.25 kg, e = 37-25 = 12 cm = 0.12 m.
Constant: g = 9.8 m/s²
Substitute into equation 3
k = (0.25×9.8)/0.12
k = 20.42 N/m.
Hence the spring constant = 20.42 N/m
It uses the corkscrew to anchor it to the cork and a lever to pull the cork out
Hope this helps buddy:D
D. is the right answer because his pressure is very bad out there in the air.
good luck
