Answer:
No.
Explanation:
The scale actually measures the force that the object does against it, and that force is called the weight.
Such that if we have an object with mass M and we are on Earth, where the gravitational acceleration is g, the weight is:
W = M*g
Now, there is a unit called "kilogram-force"
Such that on Earth, an object that has a mass of 10 kilograms, weighs 10 kilograms-force.
Then from the weight measure, we can instantly know the mass of the object, but the thing that is being measured is the weight, not the mass.
Answer:
1: Elements are substances that cannot be broken down into more substances.
2: Compounds are a group of elements in a specific ratio.
3: A metalloid is between a metal and a non-metal.
4: A physical property is a property you can see or touch.
5: A chemical property is a property seen in chemical reactions.
6: Alloys are the combination of two or more metals to make a better material.
7: An insulator doesn't let heat and sound escape.
8: Corrosion is when a metal reacts to oxygen, water, or sulfur.
9: Rust is when a metal is exposed to oxygen
Explanation:
Answer:
Knowing we only have one load applied in just one direction we have to use the Hooke's law for one dimension
ex = бx/E
бx = Fx/A = Fx/π
Using both equation and solving for the modulus of elasticity E
E = бx/ex = Fx / πex
E =
Apply the Hooke's law for either y or z direction (circle will change in every direction) we can find the change in radius
ey = (бy - v (бx + бz)) = бx
= =
Finally
ey = Δr / r
Δr = ey * r = 10 *
Δd = 2Δr =
