Answer:
191.36 N/m
Explanation:
From the question,
The Potential Energy of the safe = Energy of the spring when it was compressed.
mgh = 1/2ke²............... Equation 1
Where m = mass of the safe, g = acceleration due to gravity, h = height of the save above the heavy duty spring , k = spring constant, e = compression
Making k the subject of the equation,
k =2mgh/e²................ Equation 2
Given: m = 1100 kg, h = 2.4 mm = 0.0024 m, e = 0.52 m
Constant: g = 9.8 m/s²
Substitute into equation 2
k = 2(1100)(9.8)(0.0024)/0.52²
k = 51.744/0.2704
k = 191.36 N/m
Hence the spring constant of the heavy-duty spring = 191.36 N/m
Answer:
Gravity and Friction
Explanation:
How gravity and friction work which u probably know
Physical property is defined as a property that can be observed without changing the matter into another type of matter.
<h3>What are physical properties of matter?</h3>
Physical properties of matter are those properties which can be easily observed without a change in the composition of the substance,
Some physical properties of matter include:
- Volume
- Shape
- Density
- Taste
- Color
- Mass
- Electrical conductivity
In conclusion, physical properties do not change the composition of matter and can easily be observed.

Mercury is the closest planet to the sun.
Venus is second planet. Venus has no moons.
Earth is the third planet. This is the only planet that is known to inhabit life.
Mars is the fourth planet. Mars is called the "red planet" and has two moons.
Jupiter is the fifth planet in our solar system. Jupiter is the biggest planet in our solar system.
Saturn is the sixth planet. It has 31 moons.
Uranus is the seventh planet. It is a greenish-blue planet.
Neptune is the eight planet. On Neptune, temperatures stay colder than -350 Fahrenhiet.
Pluto is no longer a planet, but if you weighed 100 pounds on Earth, then you would weight 7-8 pounds on Pluto. But your mass would be the same.
