Net force is basically the force an object has when changing direction, so the answer would be D.
If you mean pattern designs it’s rocky bumpy and you can see the circle patterns
If you mean phases the here’s a picture
Some physical properties of matter include viscosity (maple syrup is more viscous than oil), color (an apple can be red, while a watermelon is green), opacity (a computer screen is more opaque than a window), and freezing point (ice with salt has a lower freezing point than plain ice).
Some chemical properties include pH (milk of magnesia v. wine), and heat of combustion.
Hope that helped you!
Answer:
Explanation:
Natural length of the string is given as
length of the string while block is hanging on it
extension in length is given as
now we have strain in the string is given as
similarly we will have cross-sectional area of the string is given as
now the stress in the string is given as
Now Young's Modulus is given as
