What characteristic of liquids makes them pourbale

1 answer:

8 0

Liquids are pourable because they do not maintain a "solid" structure as solids do, but still have structure, unlike gasses. Why is this? The forces between liquid particles are weaker than the forces between solid particles. The particles are further apart and move around more easily.

Have a nice day!

A sound wave from a siren has an intensity of 111.2 W/m2 at a certain point, and a second sound wave from a nearby ambulance has

Kazeer [188]

Answer:

The intensity level of the sound wave due to the ambulance is 153.5 dB.

Explanation:

The intensity level of the sound wave due to the ambulance can be calculated using the following equation:

$\beta = 10log(\frac{I}{I_{0}})$

<u>Where</u>:

I: is the intensity of the sound wave from a siren = 111.2 W/m²

I₀: is the reference intensity = 1.0x10⁻¹² W/m²

$\beta = 10log(\frac{111.2 W/m^{2}}{1.0 \cdot 10^{-12} W/m^{2}}) = 140.5 dB$

Now, since the second sound wave from a nearby ambulance has an intensity level 13 dB we have:

$I_{a} = 13 dB + 140.5 dB = 153.5 dB$

Therefore, the intensity level of the sound wave due to the ambulance is 153.5 dB.

I hope it helps you!

a rifle is used during the biathlon event in the Olympics the rifle has a mass of 2.5 kg the bullet has amass of 0.02 kg after t

Nataliya [291]

The momentum before is zero because nothing is moving. Note that because momentum is a conserved vector, the total momentum after the shot is also zero. You just have to add the products of mass and velocity in opposite directions. So the answer is zero

A 3.90 kg block is in equilibrium on an incline of 31.0◦. The acceleration of gravity is 9.81 m/s2 . What is Fn of the incline o

storchak [24]

Answer:

Explanation:

The sum of the pore along the plane is expressed according to Newton's law

Fn-Ff = ma

Fn is the moving force

Ff = nR = frictional force

m is the Mass

a is the acceleration

Substitute the given values

Fn - nR = ma

Fn - tan31°(mgcostheta) =3.9(9.8)

Fn - tan31(3.9(9.8)cos31) = 3.9(9.8)

Fn - tan31(38.22cos31)= 38.22

Fn - 32.76tan31 = 38.22

Fn-19.68 = 38.22

Fn = 38.22+19.68.

Fn = 57.90N

Hence Fn (moving force) of the inclined block is 57.90
