Explain How do the attractions between particles in a fluid determine viscosity?

Physics
1 answer:
Vikentia [17]3 years ago
6 0

Answer: Viscosity is due to particle mass, particle shape, and the strength of the attraction between the particles of a liquid. In general, the stronger the attractive forces between particles, the higher the viscosity. For many liquids, viscosity decreases when heat is applied.

A proton is launched from an infinite plane of charge with surface charge density -1.10×10-6 C/m2. If the proton has an initial
Katyanochek1 [597]

The distance covered by the proton is 48.4 m

Explanation:

The electric field produced by an electrically charged infinite plane is given by

E=\frac{\sigma}{2\epsilon_0}

where in this case,

\sigma = -1.10\cdot 10^{-6} C/m^2 is the surface charge density

\epsilon_0 = 8.85\cdot 10^{-12} F/m is the vacuum permittivity

Substituting,

E=\frac{-1.10\cdot 10^{-6}}{2(8.85\cdot 10^{-12})}=-5.65\cdot 10^4N/C

And the direction is towards the plane (because the charge is negative).

The electric force on the proton due to this field is

F=qE

where

q=1.6\cdot 10^{-19}C is the proton charge

Substituting,

F=(1.6\cdot 10^{-19})(-5.65\cdot 10^4)=-9.0\cdot 10^{-15} N

where the direction is toward the plane.

Now we can calculate the proton's acceleration using Newton's second law:

a=\frac{F}{m}

where

m=1.67\cdot 10^{-27}kg is the proton mass

Substituting,

a=\frac{-9.0\cdot 10^{-15}}{1.67\cdot 10^{-27}}=-5.4\cdot 10^{-12} m/s^2

Now we can finally apply the following suvat equation for accelerated motion to find the distance travelled by the proton:

v^2-u^2=2as

where

v = 0 is the final velocity

u=2.40\cdot 10^7 m/s is the initial velocity

a is the acceleration

s is the distance covered

And solving for s,

s=\frac{v^2-u^2}{2a}=\frac{0-(2.4\cdot 10^7)^2}{2(-5.4\cdot 10^{12})}=53.3 m

Therefore, the closest answer is 48.4 m.

Nataliya [291]

Answer:

A) mr = 100 kg

B) Fr = 210N

C) Ft = -199.5N

Explanation:

By conservation of the momentum:

mt*Vo = (mr + mt) * Vf  Solving for mr:

mr = mt*Vo / Vf - mt = 100 kg

The average force on the receiver:

mr *(Vf - 0) = Fr * Δt    Solving for Fr:

Fr = 210 N

The average force on the tackler:

mt * (Vf - Vo) = Ft * Δt    Solving for Ft:

Ft = -199.5 N
