If you walk 3m in a straight line then turn 60 degrees until you are standing at your original position then you have walked a hexagon

Here we can see that after moving for distance of d = 3 m it takes turn at 60 degree angle

this will continue till it comes to its own position

so it will look like a polygon

here Number of sides of polygon is given as

N = \frac{total Angle}{exterior angle}

now we will have

N = \frac{360}{60} = 6

So here we have total sides are 6

So here it will be a polygon of 6 sides

so it's shape will be a regular hexagon of each side as 3m length

a 1 kg box is being push across the floor. When pushed, the box accelerates at a rate of 1m/s 2. with what force is someone push
Natali5045456 [20]

Answer:

Force, F = 1 N

Explanation:

We have

Mass of a box is 1 kg

Acceleration with which it is pushed is 1 m/s²

It is required to find the force acting on the box.

Force, F = ma

F=1\ kg\times 1\ m/s^2\\\\F=1\ N

So, the force of 1 N is acting on the box.

In a game of pool, why will the balls eventually stop after a collision?
Aneli [31]

As a ball rolls ... even if there were no air resistance ... the ball
has to push down and climb over every one of those little fibers
that stick up from the felt fabric on the table.  As it does that, each
little fiber brushes against the ball, and robs a tiny tiny bit of its
kinetic energy.

At 20°C the vapor pressure of dry ice is 56.5 atm. If 10g of dry ice (solid CO2) is placed in an evacuated 0.25 L chamber at a c
jonny [76]

Answer:

Pressure of the gas is greater than the vapor pressure, therefore all the solid will not sublime.

Explanation:

To solve this problem we use ideal gas equation.

PV =nRT

If Presure of the gas (P) is greater than vapor pressure (56.5 atm), all the solid will not sublime. But If P < 56.5 atm, all of it will sublime.

where;

P is pressure of the gas in atm

V is volume of gas in Litre

T is absolute temperature of the gas in Kelvin

n is number of gas moles

R is ideal gas constant or Boltzmann constant = 0.082057 L atm K⁻¹ mol⁻¹

Given T = 20 °C  = 273 + 20 = 293K

Volume = 0.25L

n = Reacting mas (m)/Molar mass(M)

Molar mass of CO₂ = 12 + (16X2) = 12+32 = 44g/mol

Reacting mass = 10g

n = m/M ⇒ 10/44

n = 0.2273

PV =nRT ⇒ P = nRT/V

P = (0.2273X0.082057 X293)/0.25

P = 21.8596 atm

Therefore, since Pressure of the gas is greater than the vapor pressure, all the solid will not sublime.

Katie claims that steel is a homogeneous mixture, even though it looks like a
Verizon [17]

Answer:

D. Steel is made of different compounds distributed unevenly.

Explanation:

The statement that will support her claim that steel is a homogenous mixture is that steel is made up of different compounds distributed unevenly.

  • Steel is an alloy of carbon and iron in its composition.
  • Alloys are classified as mixtures.
  • Their constituent reacts differently to changed medium.
  • The iron in steel does not chemically bond with the carbon.
