What is the spring constant for a supermarket scale that stretches 0.01 m when a force of 4 N is applied
2 answers:
Answer: The spring constant for the supermarket scale is 400 N/m.
Explanation:
To calculate the spring constant, we use Hooke's Law. The formula for Hooke's law is:
where, F = Force applied on the spring = 4N
k = Spring constant = ? N/m
x = Compression or extension of the spring = 0.01m
Putting values in above equation, we get:
Hence, the spring constant for the supermarket scale is 400 N/m.

Answer: 9.0 atm
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Thus new pressure of 150 ml of a gas that is compressed to 50 ml is 9.0 atm
