What determines the state of matter for any substance
Andrews [41]

Amount of molecules present in the substance

Explanation:

In general state of matter is classified into three types based on the amount of molecules present in the matter. They are widely classified as

  • SOLID
  • LIQUID
  • GAS

SOLID

In solid the molecules are tightly packed without any free space to move inside. Therefore Solids  have strong Inter-Molecular Force of attraction and have definite shape and volume.  

LIQUID      

In Liquid the molecules are  not tightly packed. So that molecules move  freely   inside the matter. Therefore Liquids  have Weaker Inter-Molecular Force of attraction and have no definite shape and  no definite volume.

GAS

In Gas the molecules are loosely packed with  more  free space to move inside. Therefore Gas  have the weakest Inter-Molecular Force of attraction and don't have definite shape and  definite volume.

Find the vector v with the given magnitude and the same direction as u. Magnitude ||v|| = 10 Direction u = ⟨-3. 4⟩.
Alisiya [41]

Answer:

(-6,8)

Explanation:

Since v has direction as u, it must be a multiple n of u.

\sqrt{(-3n)^+(4n)^2}=10\\9n^2+16N^2 =100\\n^2=4\\n=2

therefore v = (3×2, 4×2) = (-6,8)

A 160 g air-track glider is attached to a spring. The glider is pushed in 11.2 cm and released. A student with a stopwatch finds
Yanka [14]

Answer:

k = 3.41 N/m

Explanation:

The time period is given as:

T = \frac{time\ taken}{No.\ of\ oscillations} \\\\T = \frac{19\ s}{14} \\\\T = 1.36\ s

Another formula for the time period of the spring-mass system is:

T = 2\pi\sqrt{\frac{m}{k}} \\\\(1.36\ s)^2 = 4\pi^2\frac{0.16\ kg}{k}\\\\k = \frac{(4\pi^2)(0.16\ kg)}{(1.36\ s)^2}\\\\

<u>k = 3.41 N/m</u>
