Answer:

Fs = 17.66 N

Explanation:

The force of static friction is given by the following formula:

F_s = \mu R = \mu W\\

where,

Fs = The force of static friction = ?

μ = coefficient of static friction = 0.9

W = weight of sneakers = mg

m = mass of sneakers = 2 kg

g = acceleration due to gravity = 9.81 m/s²

Therefore,

F_s = \mu mg\\F_s = (0.9)(2\ kg)(9.81\ m/s^2)\\

<u>Fs = 17.66 N</u>

A substance occupies one half of an open container. The atoms of the substance are closely packed but are still able
enyata [817]

Answer:

A substance occupies one half of an open container. The atoms of the substance are closely packed but are still able to slide past each other. The most likely phase of the substance is liquid.

A substance occupies one half of an open container. The atoms of the substance are closely packed but are still able to slide past each other. What is most likely the phase of the substance?

gas. NO. Gases have expansibility, that is, they occupy all the space available, so they wouldn't occupy just one half of the container.

liquid. YES. The description fits the liquid phase.

solid and gas. NO. Solids occupy fixed positions and their atoms can't slide past each other.

liquid and solid. NO. Solids can't be present due to their lack of movement.

A substance occupies one half of an open container. The atoms of the substance are closely packed but are still able to slide past each other. The most likely phase of the substance is liquid.

Assume that in interstellar space the distance between two electrons is about 0.8 cm. The electric force between the two electro
SIZIF [17.4K]

Answer:

F = 3.6 x 10⁻²⁴ N

Explanation:

The force of attraction or repulsion between two charges is given by the Coulomb's Law. Coulomb's Law states that:

F = kq₁q₂/r²

where,

F = Electric Force between electrons = ?

k = Coulomb's Constant = 9 x 10⁹ N.m²/C²

q₁ = q₂ = Charge on electron = 1.6 x 10⁻¹⁹ C

r = distance between electrons = 0.8 cm = 0.008 m

Therefore,

F = (9 x 10⁹ N.m²/C²)(1.6 x 10⁻¹⁹ C)(1.6 x 10⁻¹⁹ C)/(0.008 m)²

<u>F = 3.6 x 10⁻²⁴ N</u>
