When the mass of 2.0 kg is attached to the spring, the force applied to the spring is the weight of the mass, so

This force stretches the spring by

, so we can use Hook's law to find the spring constant:

Then the mass of 2.0 kg is removed and replaced with another mass m2=2.7 kg. The force produced by this mass is equal to its weight:

And so, we can use again Hook's law to calculate the new stretch of the spring:
Answer:
Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature - often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics.
Explanation:
Answer:
The flag is 16.321 meters high.
Explanation:
The situation is represented in the attached figure
In the figure we have

Given that
θ = 25.0 degrees
D = 35.0 meters
Applying values in the above equation we have
Answer:
Explanation:
Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object.
Here, We know, Density = Mass / Volume
Here, mass = 44 g
volume = 40.5 ml = 40.5 cm³
Substitute their values,
d = 44 / 40.5
d = 1.086 g/cm³
In short, Your Answer would be 1.086 g/cm³
Hope this helps!
