Highway curves are marked with a suggested speed. If this speed is based on what would be safe in wet weather, estimate the radius of curvaure for a curve marked 50km/h?The coefficient of static friction of rubber on wet concrete is .7, the coefficient of kinetic friction of rubber on wet concrete is .5 .

Answers

Answer 1

Radial (aka centripetal) acceleration keeps cars on an unbanked road in a curve. This acceleration is given by

[tex]a_{rad}= \frac{v^2}{r} [/tex]

The force required to keep in going in a circle is given by Newton's second law, F=ma. Here a is the radial acceleration from the above equation, so we get a radial force:

[tex]F_{rad}=m \frac{v^2}{r} [/tex]

This force is mediated by the friction force between the tires of the car and the road. For friction force we use the coefficient of friction and the normal force of the road on the car (which will also be the force of the car on the road). On an unbanked road this is just the weight of the car, mg.

The question now is, which coefficient of friction to use? It might surprise you to find that although the car is moving relative to the road, we should use the static coefficient. To see why this is the case, think about what the wheel's surface is doing as it meets the road. As a wheel rotates around and comes into contact with the road surface, it's bottom section is moving in a direction opposite to the car's forward movement. The point that actually touches the road is moving backward at the same speed that the car moves forward and so it is at rest with the street. If this were not the case, your tires would always be skidding on the road. (If you're having trouble seeing this, there are plenty of animations of this phenomenon on the internet). Once a car is skidding it is no longer in control and cannot turn like one that is not skidding.

So now the friction force is just

[tex]F_{fric}= \mu_s F_n=\mu_smg[/tex]

We now have to set these equal and solve for r, the radius of the circle we are traveling in. Note that mass will cancel and so we don't need to worry about the mass of the cars involved:

[tex]m \frac{v^2}{r}=\mu_smg \\ \\ \frac{v^2}{r}=\mu_sg \\ \\ \frac{v^2}{\mu_sg}=r \\ \\ \frac{(13.89m)^2}{0.7*9.8 \frac{m}{s^2} } =28.12m[/tex]

Where I have converted the speed to m/s for unit consistency.

Answer 2

The radius of curvature for wet weather is required.

The radius of curvature would be 28.1 m.

[tex]\mu_s[/tex] = Coefficient of static friction for wet concrete = 0.7

g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

m = Mass of car

v = Velocity of car = 50 km/h

The force balance is

[tex]\dfrac{mv^2}{r}=\mu_s mg\\\Rightarrow r=\dfrac{v^2}{\mu_s g}\\\Rightarrow r=\dfrac{(50\times \dfrac{1000}{3600})^2}{0.7\times 9.81}\\\Rightarrow r=28.1\ \text{m}[/tex]

The radius of curvature would be 28.1 m.

At which of the following temperature and pressure levels would a gas be most likely to follow the ideal gas law? A. 0 K and 100 Pa B. 273 K and 1 Pa C. 100 K and 273 Pa D. 273 K and 100 kPa

Answers

The Ideal Gas Law makes a few assumptions from the Kinetic-Molecular Theory. These assumptions make our work much easier but aren't true under all conditions. The assumptions are,

1) Particles of a gas have virtually no volume and are like single points.
2) Particles exhibit no attractions or repulsions between them.
3) Particles are in continuous, random motion.
4) Collisions between particles are elastic, meaning basically that when they collide, they don't lose any energy.
5) The average kinetic energy is the same for all gasses at a given temperature, regardless of the identity of the gas.

It's generally true that gasses are mostly empty space and their particles occupy very little volume. Gasses are usually far enough apart that they exhibit very little attractive or repulsive forces. When energetic, the gas particles are also in fairly continuous motion, and without other forces, the motion is basically random. Collisions absorb very little energy, and the average KE is pretty close.

Most of these assumptions are dependent on having gas particles very spread apart. When is that true? Think about the other gas laws to remember what properties are related to volume.

A gas with a low pressure and a high temperature will be spread out and therefore exhibit ideal properties.

So, in analyzing the four choices given, we look for low P and high T.

A is at absolute zero, which is pretty much impossible, and definitely does not describe a gas. We rule this out immediately.

B and D are at the same temperature (273 K, or 0 °C), but C is at 100 K, or -173 K. This is very cold, so we rule that out.

We move on to comparing the pressures of B and D. Remember, a low pressure means the particles are more spread out. B has P = 1 Pa, but D has 100 kPa. We need the same units to confirm. Based on our metric prefixes, we know that kPa is kilopascals, and is thus 1000 pascals. So, the pressure of D is five orders of magnitude greater! Thus, the answer is B.

Current = (voltage) / (resistance) = (24 V) / (24 ohms) = 1 Ampere.

#2).
To answer this question, we don't care what the
total effective resistance is.
The resistors are in parallel, so each one is connected
directly to the terminals of the battery, and each resistor
has 24 V across it.

Current through the 4-ohm resistor = (voltage) / (resistance)

= (24 V) / (4 ohms)

= 6 Amperes.

#3).
In a series circuit, the total effective resistance is
the sum of the individual resistors, and the current
is (battery voltage) / (total effective resistance).

If pone resistor is replaced with a resistor of lower resistance,
then the sum of the individuals is less, and the current in the
series circuit increases (if the battery can handle it).

Answers

The intensity of the magnetic force F experienced by a charge q moving with speed v in a magnetic field of intensity B is equal to
[tex]F=qvB \sin \theta[/tex]
where [tex]\theta[/tex] is the angle between the directions of v and B.

1) Re-arranging the previous formula, we can calculate the value of the magnetic field intensity. The charge is [tex]q=2.7 \mu C=2.7 \cdot 10^{-6}C[/tex]. In this case, v and B are perpendicular, so [tex]\theta=90^{\circ}[/tex], therefore we have:
[tex]B= \frac{F}{qv \sin \theta} = \frac{5.75 \cdot 10^{-3}N}{(2.7 \cdot 10^{-6}C)(773m/s)\sin 90^{\circ}}=2.8 T [/tex]

2) In this second case, the angle between v and B is [tex]\theta=55^{\circ}[/tex]. The charge is now [tex]q=42.0 \mu C=42.0 \cdot 10^{-6}C[/tex], and the magnetic field is the one we found in the previous part, B=2.8 T, so we can find the intensity of the force experienced by this second charge:
[tex]F=qvB \sin \theta=(42\cdot 10^{-6}C)(1.21 \cdot 10^3 m/s)(2.8 T)(\sin 55^{\circ})=0.12 N[/tex]

D. The thermal energy decreases as the wagon comes towards the bottom of the hill.,

Answers

A. As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases. Potential energy and kinetic energy are opposites. At the top of the hill the wagon has max potential energy and no kinetic energy. At the bottom of the hill the wagon has max kinetic energy and no potential energy. So as the wagon approaches the bottom of the hill potential energy decreases and kinetic energy increases.

Answer:

As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases.

Explanation:

There are two types of energy possessed in the wagon i.e. potential energy and the kinetic energy. As a wagon is accelerating down a hill, its potential energy decreases and the kinetic energy increases.

We know that the energy possessed due to its height above ground level is called its potential energy while the energy possessed due to its motion is called its kinetic energy.

So, the correct option is (A) " As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases".

Select all that apply. A hypothesis is _____. always correct determined before experimentation begins the experimental factor that changes in response to a change in the independent variable testable and falsifiable

Answers

Final answer:

A hypothesis is a testable and falsifiable assumption known before experimentation. It's not always correct and does not always change in response to a change in the independent variable. Even when experiments support a hypothesis, it is not confirmed as absolutely correct.

Explanation:

A hypothesis is a testable and falsifiable assumption based on what is known. It is determined before any experiment begins and serves as a guide for the collection and analysis of data. For instance, we could formulate a hypothesis like, 'If I water plants with sugar-mixed water, they will grow faster.'. If subsequent experimentation disproves this hypothesis, it must be discarded or reformed.

A hypothesis does not necessarily change in response to a change in the independent variable; rather, it predicts the expected response or outcome. However, a hypothesis is not always correct. It represents our best prediction based on the current information and can often be proven wrong as new data or insights become available via further empirical research.

Furthermore, in scientific research, even though a hypothesis is supported by multiple experiments, it does not confirm it to be correct, as future experiments could contradict it. Also, if a hypothesis explains a large amount of experimental data it could be considered a theory, but even theories can be modified if new data appears.

A balloon filled with helium occupies 20.0 l at 1.50 atm and 25.0◦
c. how many moles of helium will there be in the balloon at stp?

Answers

Final answer:

By applying the Ideal Gas Law, we find that the helium balloon contains approximately 1.22 moles under the given conditions. This mole amount remains consistent at standard temperature and pressure (STP) as no gas is added or removed.

Explanation:

Your question pertains to the concepts of chemical stoichiometry and the gas laws. Given the conditions and the volume of the gas, we start by converting the initial conditions to Standard Temperature and Pressure (STP). Your balloon containing helium is at a volume of 20.0 L, a pressure of 1.50 atm, and a temperature of 25.0°C (or 298.15 K in absolute temperature).

The Ideal Gas Law (PV=nRT) allows us to calculate the number of moles (n) in the balloon initially: n = PV/RT = (1.50 atm * 20.0 L) / (0.0821 L*atm/mol*K * 298.15 K) which results in approximately 1.22 mol of helium.

Now, to find the number of moles at STP, we need to remember that the number of moles remains the same as long as no gas is added or removed. Therefore, your balloon contains approximately 1.22 moles of helium at STP as well.

Volume of the balloon, [tex]\( V = 20.0 \) L[/tex]

Pressure of the helium gas,[tex]\( P = 1.50 \) atm[/tex]

Temperature of the helium gas, [tex]\( T = 25.0 \) ^\circ C[/tex]

Convert Temperature to Kelvin

First, convert the temperature from Celsius to Kelvin:

[tex]\[ T_{\text{Kelvin}} = T_{\text{Celsius}} + 273.15 \][/tex]

[tex]\[ T_{\text{Kelvin}} = 25.0^\circ C} + 273.15 \][/tex]

[tex]\[ T_{\text{Kelvin}} = 298.15 \text{ K} \][/tex]

Calculate the Number of Moles (using the Ideal Gas Law)

The ideal gas law equation relates the pressure, volume, temperature, and number of moles [tex](\( n \))[/tex] of a gas:

[tex]\[ PV = nRT \][/tex]

where:

[tex]\( P \)[/tex] is the pressure in atmospheres (atm)

[tex]\( V \)[/tex] is the volume in liters ([tex]L[/tex])

[tex]\( n \)[/tex] is the number of moles of gas

[tex]\( R \)[/tex] is the ideal gas constant, [tex]\( R = 0.0821 \) L\ atm/mol\ K[/tex]

[tex]\( T \)[/tex] is the temperature in Kelvin ([tex]K[/tex])

First, calculate [tex]\( n \)[/tex] using the ideal gas law:

[tex]\[ n = \frac{PV}{RT} \][/tex]

Now, substitute the given values:

[tex]\[ n = \frac{(1.50 \text{ atm}) \times (20.0 \text{ L})}{(0.0821 \text{ L·atm/mol·K}) \times (298.15 \text{ K})} \][/tex]

How much heat is needed to change 5.42 grams of solid gold to liquid gold at its melting point of 1,063°C? The latent heat of fusion of gold is 66.6 J/g.

Answers

[tex]5.42 \times 66.6 = 360.972[/tex]
360.972 J

Answer:

360.97 J

Explanation:

mass of gold, m = 5.42 g

Latent heat of fusion, L = 66.6 J/g

The amount of heat required to convert 1 kg of solid into liquid state at its melting point is called latent heat.

L = Heat / mass

So, L = Q / m

Q = m L

Where, Q is the amount of heat supplied and L be latent heat of fusion amd m be the mass of substance.

Q = 5.42 x 66.6

Q = 360.97 J

Thus, the amount of heat required to melt the desired amount of gold is 360.97 J.
