Answer:
0.900 mol/kg
Explanation:
Molality is moles of solute per kilograms of solvent.
Converting 54 grams of NaOH to moles:
54 g NaOH × (1 mol NaOH / 40.00 g NaOH) = 1.35 mol NaOH
So the molality is:
m = (1.35 mol) / (1.50 kg)
m = 0.900 mol/kg
Convert grams of NaOH to moles:
The formula to convert grams to moles is:[tex]\text{moles of NaOH} = \frac{\text{mass of NaOH (g)}}{\text{molar mass of NaOH (g/mol)}}[/tex]
Given that the mass of NaOH is 54 grams and its molar mass is 40.00 g/mol:
[tex]\text{moles of NaOH} = \frac{54 \text{ g}}{40.00 \text{ g/mol}} = 1.35 \text{ moles}[/tex]
Determine the mass of the solvent (water):
The mass of water is given as 1.50 kg.
Convert this mass into kilograms (if necessary):
Since 1.50 kg is already in the correct unit, no conversion is needed here.
Calculate molality (m):
The formula for molality is:
[tex]\text{molality (m)} = \frac{\text{moles of solute}}{\text{mass of solvent (kg)}}[/tex]
Substitute the values into the formula:
[tex]\text{molality} = \frac{1.35 \text{ moles}}{1.50 \text{ kg}} = 0.90 \text{ m}[/tex]
19. A young woman named Kathy Kool buys a superde-
luxe sports car that can accelerate at the rate of
16 ft/s2. She decides to test the car by dragging with
another speedster, Stan Speedy. Both start from rest,
but experienced Stan leaves 1 s before Kathy. If Stan
moves with a constant acceleration of 12 ft/s2 and
Kathy maintains an acceleration of 16 ft/s2, find
(a) the time it takes Kathy to overtake Stan, (b) the
distance she travels before she catches him, and
(c) the velocities of both cars at the instant she over-
takes him.
Answer:
a) 6.46 seconds
b) 334 feet
c) Kathy: 103 ft/s; Stan: 89.6 ft/s
Explanation:
At constant acceleration:
x = x₀ + v₀ t + ½ at²
where x is final position,
x₀ is initial position,
v₀ is initial velocity,
a is acceleration,
and t is time.
For Kathy, x₀ = 0 ft, v₀ = 0 ft/s, a = 16 ft/s², and t = t.
For Stan, x₀ = 0 ft, v₀ = 0 ft/s, a = 12 ft/s², and t = t + 1.
Kathy:
x = 0 + (0) t + ½ (16) t²
x = 8t²
Stan:
x = 0 + (0) (t + 1) + ½ (12) (t + 1)²
x = 6 (t + 1)²
a) When Kathy overtakes Stan, they have the same position:
8t² = 6 (t + 1)²
8t² = 6 (t² + 2t + 1)
8t² = 6t² + 12t + 6
2t² − 12t − 6 = 0
t² − 6t − 3 = 0
Solving with quadratic formula (or complete the square):
t = [ -(-6) ± √((-6)² − 4(1)(-3)) ] / 2(1)
t = [ 6 ± √(36 + 12) ] / 2
t = (6 ± √48) / 2
t = (6 ± 4√3) / 2
t = 3 ± 2√3
Since t > 0, t = 3 + 2√3 ≈ 6.46 seconds.
b) Kathy's position when she overtakes Stan is:
x = 8t²
x = 8 (3 + 2√3)²
x ≈ 334 feet
c) To find the final velocities, we use:
v = at + v₀
For Kathy:
v = (16) (3 + 2√3) + 0
v ≈ 103 ft/s
For Stan:
v = (12) (3 + 2√3 + 1) + 0
v ≈ 89.6 ft/s
List and Explain three ways study groups benefit your learning
Answer:
Explanation:
Find a new perspective.The other members of the study group will have different ideas and perspectives to their own, thus generating different ways of understanding a topic. When you study, you only have one vision, however, by doing it in company, your own knowledge is enriched and you can understand the concepts globally.
MotivationIt is another advantage of studying in a group. Being alone, he turns around before sitting down to study, looking for excuses and wasting time. On the other hand, when having a study appointment, you must meet a schedule, taking advantage of the moment to just study. They will also encourage each other to continue studying. In short, you cannot postpone studies as you would if you were studying alone.
Eliminate boredom.Joining a study group generally makes the act of studying a little less monotonous. You should try to put together a group with those who understand the subject and are responsible, and the ideal is to enjoy the entire study process in company.
Answer:
Look at things from a different angle.
Other members of the study group will have different views and viewpoints than they do, resulting in a variety of approaches to a topic. When you study, you only have one vision; but, when you do it in a group, your knowledge expands and you may grasp topics more broadly.
Motivation
Another benefit of studying in a group is this. He turns around before settling down to study because he is alone, looking for reasons and wasting time. When you have a study appointment, on the other hand, you must stick to a timetable and use the time to study. They will also motivate one another to keep learning. In other words, you won't be able to postpone your studies like you would if you were studying alone.
Explanation:
A man pushes a lawn mower with a force of 25 newtons. The lawn mower has a mass of 17 kilograms and the handle makes an angle of 60 degrees with the horizontal. How much work is done if the lawn mower is pushed a total of 500 meters
Answer:
6250 J
Explanation:
Work is the distance times the component of the force along that distance.
The horizontal component of the force is:
25 N × cos(60°) = 12.5 N
So the work done is:
W = (500 m) (12.5 N)
W = 6250 J
To calculate the work done by the man on the lawn mower, we use the formula Work = Force imes Distance times cos( heta). The horizontal component of the force is determined and then multiplied by the distance to get a total work done of 6250 joules.
Calculating Work Done When Pushing a Lawn Mower
To calculate the work done on an object, you can use the formula Work (W) = Force (F) times Distance (d) times cos( heta), where heta is the angle between the force and the direction of movement. For the man pushing the lawn mower, the force is 25 newtons, the distance is 500 meters, and the angle is 60 degrees with the horizontal.
First, calculate the horizontal component of the force:
Fhorizontal = F times cos(heta)
Fhorizontal = 25 N times cos(60°)
Fhorizontal = 25 N times 0.5
Fhorizontal = 12.5 N
Next, calculate the work done using the horizontal component of the force:
W = Fhorizontal times d
W = 12.5 N times 500 m
W = 6250 J (joules)
Therefore, the work done by the man on the lawn mower when pushing it 500 meters is 6250 joules.

Answer:
Beth went back toward her origin
Explanation:
Please, see the attached image that represent's Beth's path.
She started her walk 2 meters from the origin (0) and after 6 seconds she headed back to position zero (0) the origin. Notice the second half of the graph as a segment going down, thus reducing her distance from the origin, and getting closer to it.
Answer:
Beth went back toward her origin.
Beth speed up considerably.
Explanation:
speed of the object is defined as the slope of the position time graph
here we know that
initially it moves from t = 0 to t = 6 from x = 2 to x = 8
so the slope is given as
[tex]v = \frac{x_2 - x_1}{t_2 - t_1}[/tex]
[tex]v = \frac{8 - 2}{6 - 0}[/tex]
[tex]v = 1 m/s[/tex]
similarly for next we have
again it comes to x = 0 after t = 10 s
so the speed is
[tex]v_2 = \frac{x_3 - x_2}{t_3 - t_2}[/tex]
[tex]v_2 = \frac{0 - 8}{10 - 6}[/tex]
[tex]v_2 = -2 m/s[/tex]
so here the velocity is negative which shows that it will move in reverse direction also its velocity is also increase
so correct answers are
Beth went back toward her origin.
Beth speed up considerably.

You measure the voltage difference of a circuit to be 15 Volts and the resistance to be 675 Ohms.
What is the current in the circuit? (Show the appropriate equation and show your work with units)
Answer:
0.0222 A
Explanation:
V = I*R
[tex]15v = 675ohms \times i \\ i = \frac{15v}{675ohms} = 0.0222 a [/tex]
Using Ohm's law, which is I = V/R, the current I is calculated by dividing the voltage V (15V) by the resistance R (675Ω), resulting in a current of 22.2 milliamps.
The student is asking how to calculate the current in a circuit when given the voltage and resistance. To find the current (I), we use Ohm's law, which is represented by the equation I = V/R, where I is the current in amperes (A), V is the potential difference in volts (V), and R is the resistance in ohms (
). To solve the student's problem:
Voltage (V) = 15 Volts
Resistance (R) = 675 Ohms
Plugging these values into Ohm's law:
I = V/R
I = 15V / 675 Ω
I = 0.0222 A or 22.2 mA (Milliamps)
Therefore, the current in the circuit is 22.2 milliamps.
A car travels 12 kilometers due north and then
8 kilometers due west going from town A to
town B. What is the magnitude of the displacement
of a helicopter that
ies in a straight line from
town A to town B?
Answer:
14.42km
Explanation:
Given that the car traveled 12km due north, then 8 km due west going from town A to B, this can be represented on x-y plane as ( vectors) 12 units up and the 8 units to the left .
In doing so , the magnitude of displacement will be the square-root of the sum of squares of the two vectors
Magnitude =[tex]\sqrt{12^2+8^2} \\\\=\sqrt{144+64} \\\\\\=\sqrt{208} \\\\\\=14.42km[/tex]
If a car travels 12 kilometers due north and then 8 kilometers due west going from town A to town B. The magnitude of the displacement of a helicopter that flies in a straight line from town A to town B will be 14 km
Using this formula
Magnitude of the displacement=√North kilometers ²+West kilometers ²
Where:
North=12 kilometers
West=8 kilometers
Let plug in the formula
Magnitude of the displacement=√12²+8²
Magnitude of the displacement=√144+64
Magnitude of the displacement=√208
Magnitude of the displacement=14 km
Inconclusion If a car travels 12 kilometers due north and then 8 kilometers due west going from town A to town B. The magnitude of the displacement of a helicopter that flies in a straight line from town A to town B will be 14km

A particle moves in a straight line. Its speed(v)
increases linearly with time. If the initial speed of
the particle is vo and its speed at t = 4 s is 2V
then integration of vdt from 0 to 4 is
(1) Zvo
(3) 6v
(2) 8vo
(4) AVO
Answer:
[tex]6v_0[/tex]
Explanation:
The speed of the particle increases linearly with time, so we can write it as
[tex]v(t) = kt+v_0[/tex]
where k is the a certain constant of proportionality and [tex]v_0[/tex] is the initial speed.
We also know that at t = 4 s, the speed is [tex]v=2v_0[/tex], so we can use this information to find k:
[tex]v(4) = 4k+v_0 = 2v_0 \rightarrow k = \frac{v_0}{4}[/tex]
So the complete expression of v(t) is
[tex]v(t) = \frac{v_0}{4}t+v_0 = v_0 (\frac{t}{4}+1)[/tex]
Now we integrate the quantity [tex]v(t)[/tex], and we find:
[tex]\int {v(t)} \, dt =\int (\frac{v_0}{4}t+v_0) \, dt =\frac{v_0}{8}t^2 + v_0 t[/tex]
Substituting the limit of integration t = 4, we find:
[tex]\frac{v_0}{8}4^2 + 4v_0 =2v_0+4v_0 = 6v_0[/tex]
And substituting t = 0, we find 0. So, the result of the integration from 0 to 4 is
[tex]6v_0[/tex]
In any circuit, current is inversely proportional to:
potential

2. Now imagine that the car is on a rectangular track that is 30 cm on each short side and 60 cm on each long
side. The car begins at the 0 cm position and takes one trip around the track.
a
What is the displacement of the car?
b.
What is the total distance that the car travels?
Answer:
distance is 180 displacement is 0
Explanation:
Displacement is the distance between one point to another directly in only one direction but distance is the distance traveled altogether in any direction.
The displacement of the car traveling around a rectangular track and returning to the starting point is zero, while the total distance traveled by the car is the sum of all sides of the rectangle, thus 180 cm.
Explanation:In physics, displacement is defined as the shortest distance from the initial to the final position of a point. Therefore, if a car starts from a point on the track and makes a round trip back to the same point, the displacement of the car is zero.
Total distance traveled by the car, however, is the total length of the path covered by the car. The track is a rectangle with width 30 cm (short side) and length 60 cm (long side). Thus the total distance is calculated by adding up the lengths of all sides of the rectangle (2*30 cm + 2*60 cm) which equals 180 cm.

How do you find velocity on a position/time graph?
Well, to find velocity, you need to divide the change in position by the change in time. So on your graph, find two points. Find the change in position and time in those two points, these can be any two points on the graph. Then you can divide the change in position by the change in time. (I know this explanation is confusing so hopefully what I included below can help.)
Velocity = x1 - x2 divided by t1 - t2

In order to decrease the friction an object experiences, you can either change
the surface it sits on or you can_______its weight.
Answer:
Reduce its weight
Explanation:
For an object on a flat surface, the maximum force of friction experienced by the object is given by:
[tex]F = \mu W[/tex]
where
[tex]\mu[/tex] is the coefficient of friction
W is the weight of the object
As we can see from the formula, there are two ways of reducing the friction:
- Decreasing [tex]\mu[/tex] --> this coefficient depends on the material and on the roughness of the surface, so this can be changed by changing the properties of the surface
- Decreasing W, the weight --> this can be done by reducing the mass of the object

When a number is written in scientific notation (representing the number using powers of base ten) it is expressed so that it contains a digit in the place of the units and all other digits after the decimal point, multiplied by the respective exponent.
Then, the significant digits will be the digits that are before the power of ten.
In the case of [tex]0.00069[/tex] we have to move the decimal point to the right and the power of base ten will be equal to the spaces moved to the right:
[tex]0.00069=6.9(10)^{-4}[/tex]

Jose gets up from his seat on the bus to move closer to the front. Just as he begins to walk forward, the bus stops at a light. What is the best explanation of what happens to Jose?
Answer:
According to first law of motion, a body continues to be in state of rest or motion unless an unbalanced force acts on it.
When the bus stops, Jose feels a sudden forward motion. This is due to the inertia of motion. In the bus, Jose has same speed as the bus while sitting. When she gets and starts moving, the bus stops at the light. But due to the inertia of motion, Jose feels a sudden forward motion before she finally stops.
