Answer:

A) Liquids with high viscosity do not flow as well as liquids with low viscosity.

Explanation:

Viscosity is the property of layer of fluids which will flow relative to each other.

As we know that when two layers are moving on each other then due to cohesive force between the molecules the layers do not move freely.

If the cohesive force is strong between the molecules then we can say that liquid is of high viscosity which means that liquid can not move easily.

So here the correct option is

A) Liquids with high viscosity do not flow as well as liquids with low viscosity.

high viscosity of liquid means strong force between the layers which means layers can not move easily with respect to each other

Viscosity of liquids is essentially the 'thickness' of the liquid. For instance, honey and water have different viscosities. Honey has a higher one and therefore, liquids with high viscosity do not flow as well as liquids with low viscosity (water).

The magnitude of the electric force between two protons is 2.30 10-26 n. how far apart are they?

SCORPION-xisa [38]

The electric force between two charge objects is calculated through the Coulomb's law.
F = kq₁q₂/d²
The value of k is 9.0 x 10^9 Nm²/C² and the charge of proton is 1.602 x10^-19 C. Substituting the known values from the given,
2.30x10^-26 = (9.0 x 10^9 Nm²/C²)(1.602 x10^-19C)²/d²
The value of d is equal to 0.10 m.

Answer:

1) x_total = 2.7 km=2700 m, 2) t_total = 1926 s, 3) v_avg = 1.40 m / s

Explanation:

1) To solve this uniform velocity problem, we must find the displacement of each part and add them.

x_total = x₁ + x₂

x_total = 0.7 + 2.0

x_total = 2.7 km

2) how long does it take for this tour

truck

v = x₁ / t₁

t₁ = x₁ / v

t₁ = 0.7 / 20

t₁ = 0.035 h

Let's reduce the time to the SI system

t₁ = 0.035 h (3600 s / 1h) = 126 s

when he is walking

t₂ = 30 min (60 s / 1min) = 1800 s

the total time is

t_total = t₁ + t₂

t_total = 126 + 1800

t_total = 1926 s

3) the average velocity is defined as the displacement in the inerval between time

v_avg = x_total / t_total

v_avg = 2700/1926

v_avg = 1.40 m / s
