Answer:

Explanation:

The solid state is one of the 3 stages which matter undergoes in addition to the liquid and the gaseous state. Matter in it's solid state contains atoms which are closely packed, In this stage, matter exhibits the least amount of kinetic energy of all three stages hence hindering movement of its particles and exhibiting firmness and rigidity. Solids exhibits a regular arrangement of it's molecules which differs from the scattered nature of gaseous particles and slightly ordered nature of liquid molecules. Solids exhibits a defined volume , and shape with molecules held together by string attractive forces. Solids can change into liquid through melting or transform directly into gaseous state through sublimation.

Elis [28]

Answer:

   ω = ω₀ + α t

      ω² = ω₀² + 2 α  θ

      θ = θ₀ + ω₀ t + ½ α t²

Explanation:

Rotational kinematics can be treated as equivalent to linear kinematics, for this change the displacement will change to the angular displacement, the velocity to the angular velocity and the acceleration to the angular relation, that is

     x → θ

     v → ω

     a → α

with these changes the three linear kinematics relations change to

      ω = ω₀ + α t

      ω² = ω₀² + 2 α  θ

      θ = θ₀ + ω₀ t + ½ α t²

where it should be clarified that to use these equations the angles must be measured in radians

Compare and contrast speed and velocity
Alex73 [517]
Where speed is distance/time, velocity is displacement/time. 

What this means is that velocity is the length covered in relation to the starting point. 
Speed is just the distance travelled no matter where you began. 

When going around a circular track, you might have a speed value. However, since you get back to the same location at every lap, you have 0 velocity. 

Hope I helped :)

V125BC [204]

Answer:

F = 1.24*10^4 N

Explanation:

Given

Depth of the ship, h = 25 m

Density of water, ρ = 1.03*10^3 kg/m³

Diameter of the hatch, d = 0.25 m

Pressure of air, P(air) = 1 atm

Pressure of water =

P(w) = ρgh

P(w) = 1.03*10^3 * 9.8 * 25

P(w) = 2.52*10^5 N/m²

P(net) = P(w) + P(air) - P(air)

P(net) = P(w)

P(net) = 2.52*10^5 N/m²

Remember,

Pressure = Force / Area, so

Force = Area * Pressure

Area = πr² = πd²/4

Area = 3.142 * 0.25²/4

Area = 3.142 * 0.015625

Area = 0.0491 m²

Force = 0.0491 * 2.52*10^5

F = 12373 N

F = 1.24*10^4 N
