Answer:
6.22 N/m
Explanation:
From Hooke's law we deduce that F=kx where F is the applied force and k is the spring constant while x is the extension or compression of the spring. Making k the subject of the above formula then
We also know that the force F is equal to mg where m is the mass of an object and g is acceleration due to gravity hence substituting F with mg we get that
Substituting m with 425 g which is equivalent to 0.425 kg and g with 9.81 then 0.67 for x we get that
Therefore, the spring constant is approximately 6.22 N/m
Answer:
20000 pounds
Explanation:
Generally 1 gallon of fuel burnt gives of 20 pounds of CO₂
Difference in the gallons of fuel burnt
The 20 mpg car burns 1000 gallons of fuel more than the 30 mpg car
The amount of CO₂ would be
The fewer pounds that the 30 mpg car would release is 20000 pounds
