The diagram shows movement of thermal energy. At bottom a fire has red curved lines labeled Y with arrowheads pointing upward to

a pot. In the pot are red balls at the bottom and blue balls at the top. Black lines with arrowheads point upward from the red balls in the center of the pot, and black curved lines labeled W with arrowheads point downward from the blue balls along the sides of the pot. The handle of the pot is red near the pot and labeled X. The pot handle is held by a hand labeled Z. In which areas of the diagram does conduction occur? W and X X and Z Y and Z Z and W

Answer:

X and Z

Explanation:

Conduction occurs through direct physical contact.  Heat transferred from the pot to the handle, and from the handle to the hand, are both examples of conduction.

If a 5.0 kg box is pulled simultaneously by a 10.0 N force and a 5.0 N force, then its acceleration must be Group of answer choi
vivado [14]

Answer:

We cannot tell from the information given

Explanation:

Given;

mass of the box, m = 5 kg

first force, F₁ = 10 N

second force, F₂ = 5 N

(I) Assuming the two forces are acting horizontally in opposite direction, the resultant force on the box is calculated as;

∑Fx = 10 N - 5 N

      = 5 N

Apply Newton's second law of motion;

∑Fx = ma

a = ∑Fx/m

a = 5 / 5

a = 1 m/s² in the direction of the 10 N force.

(II) Also, if the two forces are acting in the same direction, the resultant force is calculated as;

∑Fx = 10 N + 5 N

∑Fx = 15 N

a = 15 / 5

a = 3 m/s²

Therefore, the information given is not enough to determine the acceleration of the box.

Duplain St. is 300 m long and runs from west to east between Baron and Burkey. If Keith is strolling east from Baron at an avera
Ivahew [28]

Sue from Burkey and Keith from Baron will meet in 2 minutes

Answer: Option b

<u>Explanation:</u>

Time taken can be calculated when distance and the speeds are given. Here speeds of Keith and Sue are given. So, we have to find the relative speeds in order to calculate the time taken.

When two objects travel in same direction the relative speed will be the difference between speeds. Similarly when two objects travel in opposite direction, the relative speed will be the sum of given speeds.

Given:

Speed of Sue from Burkey is 6 km/hr and speed of Keith from Baron is 3 km/hr.

The distance between Burkey and Baron is 300 m.

From the formula, d=s \times t

where d is distance,s is speed and t is time

It can be derived that, t=\frac{d}{s}

s = sum of given speeds = 3 km/hr + 6 km/hr = 9 km/hr

d = 300 m = 0.3 km \text {Time }=\frac{0.3 \mathrm{km}}{9 \mathrm{km} / \mathrm{hr}}=\frac{1}{30} h r=2 \text { minutes }

How many liters are in 0.034 moles of chlorine gas?
Anuta_ua [19.1K]

The volume of the gas is 7.6\cdot 10^{-4}m^3

Explanation:

At standard temperature and pressure (stp), the volume occupied by 1 mole of an ideal gas is always equal to

V=22.4 L

In this problem, we have an amount of moles of gas of

n = 0.034 mol

Since 1 mol of gas occupies a volume of 22.4 L, we can set up the following ratio:

\frac{1 mol}{22.4 L}=\frac{0.034 mol}{V}

where V is the volume occupied by 0.034 mol of gas. Solving for V, we find

V=\frac{0.034 mol}{1 mol}(22.4 L)=0.76 L

Or, in cubic metres,

V=0.76 L = 7.6\cdot 10^{-4}m^3
