Answers

Explanation:

When Two Samples of Water are Mixed, what Final Temperature Results?

Go to Mixing Two Amounts of Water: Problems 1 - 10

Go to calculating the final temperature when mixing water and a piece of metal

Worksheet #2

Back to Thermochemistry Menu

Example #1: Determine the final temperature when 32.2 g of water at 14.9 °C mixes with 32.2 grams of water at 46.8 °C.

This is problem 8a from Worksheet #2.

First some discussion, then the solution. Forgive me if the points seem obvious:

1) The colder water will warm up (heat energy "flows" into it). The warmer water will cool down (heat energy "flows" out of it).

2) The whole mixture will wind up at the SAME temperature. This is very, very important.

3) The energy which "flowed" out (of the warmer water) equals the energy which "flowed" in (to the colder water)

This problem type becomes slightly harder if a phase change is involved. For this example, no phase change. What that means is that only the specific heat equation will be involved

Solution Key Number One: We start by calling the final, ending temperature 'x.' Keep in mind that BOTH water samples will wind up at the temperature we are calling 'x.' Also, make sure you understand that the 'x' we are using IS NOT the Δt, but the FINAL temperature. This is what we are solving for.

The warmer water goes down from to 46.8 to x, so this means its Δt equals 46.8 − x. The colder water goes up in temperature, so its Δt equals x − 14.9.

That last paragraph may be a bit confusing, so let's compare it to a number line:

To compute the absolute distance, it's the larger value minus the smaller value, so 46.8 to x is 46.8 − x and the distance from x to 14.9 is x − 14.9.

These two distances on the number line represent our two Δt values:

a) the Δt of the warmer water is 46.8 minus x

b) the Δt of the cooler water is x minus 14.9

Solution Key Number Two: the energy amount going out of the warm water is equal to the energy amount going into the cool water. This means:

qlost = qgain

However:

q = (mass) (Δt) (Cp)

So:

(mass) (Δt) (Cp) = (mass) (Δt) (Cp)

With qlost on the left side and qgain on the right side.

Substituting values into the above, we then have:

(32.2) (46.8 − x)(4.184) = (32.2) (x − 14.9) (4.184)

Solve for x

Пояснение:

Найдите эскиз прилагаемой схемы. Масса бревна M размещается на отметке 3 см от толстого конца, а стержень размещается на отметке 6 см от массы бревна.

Согласно принципу момента, сумма момента по часовой стрелке равна сумме момента против часовой стрелки.

Вес корпуса в более тонкой части W = мг

W = 60 × 10 = 600 Н

Момент по часовой стрелке = 600 × 9

CW момент = 5400 Нм

Момент против часовой стрелки = M × 6

Момент ACW = 6M

Уравнять оба момента

6M = 5400

М = 5400/6

М = 900Н

Масса бревна = 900/10

Масса бревна = 90кг

If you run east for 38m, stop suddenly, run another 27m east, then you run west for 47
m, what is your total displacement?
how to answer: #m, direction

Answers

Answer:

Total Displacement = -18m

Explanation:

Given

East Movement = 38m and 27m

West Movement = 47m

Required

Determine the total displacement

To answer this, we consider east as negative direction and the west as positive (using logics of number line).

Total Displacement = East Movement + West Movement

Total Displacement = -38m - 27m + 47m

Total Displacement = -18m

Hence, the total displacement is 18m towards East

Please help!! The graph in the figure shows the position of a particle as it travels along the x-axis. What is the magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s?

Answers

The uniform movement allows to find the average speed, for which the correct answer is:

        B) 1.3 m / s

Kinematics studies the movement of bodies, establishing relationships between position, velocity and acceleration. In the special case that the acceleration is zero the motion is called uniform motion.

        v = [tex]\frac{\Delta x}{\Delta t}[/tex]

Where v is the velocity, Δx is the position variation and Δt is the time variation in the analyzed interval.

In this case

         v = [tex]\frac{2.0 - (-2.0)}{4.0\ -1.0}[/tex]

          v = 1.33 m / s

In conclusion using the uniform motion ratios we can find that the correct answer for the average velocity is

        B) 1.3 m / s

the solubility of sugar is 30 degree Celsius at 220 what does it mean​

Answers

Answer:

So, that if you put 100 mL of 30 degree water in a beaker, you could add up to 220 grams of sugar and it would eventually dissolve. In other words, that mass of sugar should dissolve in 100 mL of water to make a solution that is just saturated.

The solubility of sugar is 30° C at 220. This means 220g of sugar is dissolved in 100g of solvent to make the saturated solution at 30° C. Solutions.

What is the solution?

Most frequently, the solubility is represented in terms of mass per volume of water. Solubilities are frequently stated as g/100 mL, g/100 g, or g/L of water.

The ratio you provided is probably 1 g of sugar to 100 mL of water. In other words, if you put 100 mL of water at 30 degrees in a beaker, you could add up to 220 grams of sugar, and it would finally dissolve.

To generate a solution that is just saturated, the mass of sugar should dissolve in 100 mL of water.

Therefore, at 220 degrees, sugar dissolves at 30 degrees. This indicates that to create the saturated solution at 30° C, 220g of sugar must be dissolved in 100g of solvent.

You row a boat perpendicular to the shore of a river that flows at 3 m/s. The velocity of your boat is 4 m/s relative to the water. What is the velocity of your boat relative to the shore?

Answers

Answer:

The velocity vBW of the boat relative to the water is 4.0 m/s, directed perpendicular to the current, as in Figure 3.18.

Explanation:

The boat is perpendicular to the shore. Then the net velocity of the boat with respect to river is 5 m/s. The observer feels like the boat is moving slower than they appear actually.

What is relative velocity ?

Relative velocity is velocity of an object measured with respect to other object which can be of stationary or moving with a speed. Thus speed relative to another object is called the relative velocity.

The relative velocity is what's the speed for an observer but it differs from actual velocity. Sometimes it may slower or faster depending on the object with which a we are relating the speed.

Given that the speed of the boat = 4 m/s

speed of river = 3 m/s.

Both are perpendicular and the net velocity of the boat is :

r = √(3² + 4²) = 5 m/s.

Hence, the velocity of the boat relative to the shore will be 5 m/s.

How far will a 600kg boat travel in 12 s if there is a constant 900N force on it and it starts from rest?

Answers

Answer:

d = 108 m

Explanation:

Given that,

Initial speed, u = 0

Mass of the boat, m = 600 kg

Time, t = 12 s

Force on boat, F = 900 N

Firstly, we can find the acceleration of the boat using formula, F = ma

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{900\ N}{600\ kg}\\\\a=1.5\ m/s^2[/tex]

Let it will travel d distance. Using second equation of motion to find it as follows :

[tex]d=ut+\dfrac{1}{2}at^2\\\\d=0+\dfrac{1}{2}\times 1.5\times (12)^2\\\\d=108\ m[/tex]

north pole
O C. They loop from the south pole to the south pole and from the
north pole back to the north pole.
OD. No consistent pattern exists in the lines.

Answers

Answer:

It’s option B

Explanation:

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

The magnetic field lines are the points towards the south pole of magnet and are away from the north pole. Thus, option B is correct.

What are magnetic field lines?

A North magnetic pole would move along magnetic field lines, which are lines drawn in a magnetic field. Magnetic lines of force are another name for the magnetic field lines.

The north pole serves as the starting point for magnetic lines of force, which end at the south pole. They won't ever cross over each other.

Small compasses will point away from the magnet's north pole and toward its south pole when used to map the magnetic field surrounding a bar magnet.

Therefore, the magnetic field lines are given to have direct attention away from the north pole of a magnet and toward its south pole.
