Explanation:

The direction of the magnetic force on a 1.00 cm section of a wire can be determined based on the orientation of the magnetic field. In this case, the magnetic-field direction is specified as 20.0° south of west.

To determine the direction of the magnetic force, we can apply the right-hand rule. By pointing the thumb of the right hand in the direction of the current flow (from positive to negative), and aligning the fingers with the magnetic-field direction (20.0° south of west), the palm of the hand will indicate the direction of the magnetic force.

However, without additional information about the orientation of the wire with respect to the magnetic field, it is not possible to determine the exact direction of the magnetic force on the wire section. The orientation of the wire, whether it is perpendicular, parallel, or at an angle to the magnetic field, will affect the direction of the magnetic force.

To accurately determine the direction of the magnetic force, it is essential to know the specific configuration and orientation of the wire in relation to the magnetic field. Additional details regarding the setup would allow for a more precise analysis of the forces involved.

Answer:

No machine is free from the effects of gravity, and even with wonderful lubrication, friction always exists. The energy a machine produces is always less than the energy put into it (energy input). ... That is why 100% efficiency in machines shall not be possible.

Answer:The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent.

Explanation:

Answer: the coefficient of friction

Explanation:

The magnitude of frictional force is \(\mu\)N and the magnitude of the force is N. So if we take the ratio of it we will get  \(\mu\) In result.

The friction coefficient is the ratio of the normal force pressing two surfaces together to the frictional force preventing motion between them. Typically, the Greek letter is used to symbolize it, i.e., \(\mu\). In mathematical terms, is equal to F/N, where F represents frictional force and N represents normal force. Since both F and N are measured in units of force, the coefficient of friction is a dimensional less quantity (such as newtons or pounds).

For both static and kinetic friction, the coefficient of friction has a range of values. When an object experiences static friction, the frictional force resists any applied force, causing the object to stay at rest until the static frictional force is removed. In kinetic friction, the frictional force resists the motion of the object.

Answer:

The roadrunner will take approximately 5.285 seconds to catch up to the rattlesnake.

Explanation:

From the statement we notice that:

1) Rattlesnake moves a constant speed (\(v_{S} = 0.75\,\frac{m}{s}\)), whereas the roadrunner accelerates uniformly from rest. (\(v_{o, R} = 0\,\frac{m}{s}\), \(a = 1\,\frac{m}{s^{2}}\))

2) Initial distance between the roadrunner and rattlesnake is 10 meters. (\(x_{o, R} = 0\,m\), \(x_{o,S} = 10\,m\))

3) The roadrunner catches up to the snake at the end. (\(x_{S} = x_{R}\))

Now we construct kinematic expression for each animal:

Rattlesnake

\(x_{S} = x_{o,S}+v_{S}\cdot t\)

Where:

\(x_{o, S}\) - Initial position of the rattlesnake, measured in meters.

\(x_{S}\) - Final position of the rattlesnake, measured in meters.

\(v_{S}\) - Speed of the rattlesnake, measured in meters per second.

\(t\) - Time, measured in seconds.

Roadrunner

\(x_{R} = x_{o,R} +v_{o,R}\cdot t +\frac{1}{2}\cdot a\cdot t^{2}\)

Where:

\(x_{o, R}\) - Initial position of the roadrunner, measured in meters.

\(x_{R}\) - Final position of the roadrunner, measured in meters.

\(v_{o,R}\) - Initial speed of the roadrunner, measured in meters per second.

\(a\) - Acceleration of the roadrunner, measured in meters per square second.

\(t\) - Time, measured in seconds.

By eliminating the final positions of both creatures, we get the resulting quadratic function:

\(x_{o,S}+v_{S}\cdot t = x_{o,R}+v_{o,R}\cdot t +\frac{1}{2}\cdot a \cdot t^{2}\)

\(\frac{1}{2}\cdot a \cdot t^{2} + (v_{o,R}-v_{S})\cdot t + (x_{o,R}-x_{o,S}) = 0\)

If we know that \(a = 1\,\frac{m}{s^{2}}\), \(v_{o, R} = 0\,\frac{m}{s}\), \(v_{S} = 0.75\,\frac{m}{s}\), \(x_{o, R} = 0\,m\) and \(x_{o,S} = 10\,m\), the resulting expression is:

\(0.5\cdot t^{2}-0.75\cdot t -10=0\)

We can find its root via Quadratic Formula:

\(t_{1,2} = \frac{-(-0.75)\pm \sqrt{(-0.75)^{2}-4\cdot (0.5)\cdot (-10)}}{2\cdot (0.5)}\)

\(t_{1,2} = \frac{3}{4}\pm \frac{\sqrt{329}}{4}\)

Roots are \(t_{1} \approx 5.285\,s\) and \(t_{2}\approx -3.785\,s\), respectively. Both are valid mathematically, but only the first one is valid physically. Hence, the roadrunner will take approximately 5.285 seconds to catch up to the rattlesnake.

The wavelength of light emitted by hydrogen corresponding to n = 3 is 656.3 nm.

The equation for the Balmer series of hydrogen is:

\(1/λ = B (1/2^2 - 1/n^2)\)

where λ is the wavelength of the emitted light, B is a constant equal to 1.097 × 10^7 m^-1, and n is an integer corresponding to the energy level of the electron in the hydrogen atom.

We want to find the wavelength of light emitted by hydrogen corresponding to n = 3.

Substituting this value into the equation, we get:

\(1/λ = B (1/2^2 - 1/3^2)\)

Simplifying the right-hand side, we get:

1/λ = B (1/4 - 1/9) = B (5/36)

Multiplying both sides by λ, we get:

λ = 1/(B (5/36))

Substituting the value of B = 1.097 × 10^7 m^-1, we get:

\(λ = 1/(1.097 × 10^7 m^-1 × 5/36)\) = 656.3 nm

Therefore, the wavelength of light emitted by hydrogen corresponding to n = 3 is 656.3 nm.

The period of pendulum is still the same at 1.4 seconds.

We need to know about pendulum experiment to solve this problem. The pendulum is a simple experiment to calculate gravitational acceleration. The gravitational acceleration can be calculated by

g = 4π² . L / T²

where g is gravitational acceleration, L is the length of the string and T is the period.

From the question above, we know that:

L = 0.5 meters

m1 = 1 kg

θ = 12⁰

m2 = 2 . m1

T1 = 1.4 seconds

Find the period of pendulum

g = 4π² . L / T²

T² = 4π² . L / g

T = √(4π² . L / g)

The period of a pendulum does not depend on the mass of the object, hence the period is still the same at 1.4 seconds.

Explanation:

The electric potential energy of the charge will be =3.5*10^8 J  

Electric potential energy is the energy that is needed to move a charge against an electric field.

F=Force experienced by the charge = 3.6*10^-4 N

q1 = magnitude of charge producing the electric field

q2 = magnitude of charge experiencing the electric force

r1 = distance between the two charges

Electric force experienced by the charge is given using coulomb's law as

\(F=\dfrac{kq_1q_2}{r^2}\)

\(3.6\times 10^{-4}=\dfrac{9\times 10^9 q_1q_2}{(9.8\times 10^{-5})^2}\)

\(q_1q_2=3.84\times 10^{-22}\)

Electric potential energy of the charge can be given as

\(U=\dfrac{kq_1q_2}{r}\)

\(U=\dfrac{(9\times 10^9)q_1q_2}{(9.8\times 10^{-5})^2}\)

\(U=3.5\times 10^{-8}\ J\)

Thus Electric potential energy of the charge can be given as \(U=3.5\times 10^{-8}\ J\)

A sprinter sprints by pushing forward on the ground, which generates a backward force on the sprinter. This backward force is the only horizontal force acting on the sprinter, causing her to accelerate forward. The sprinter does not push backward on the ground, as this would generate a forward force on her, opposing her forward motion.

Explanation:

U₂ = 0 V. The lamp (L₂) is short circuited, meaning that there is no resistance between its terminals. As such, the voltage across its terminals must be zero.

Resistance is a concept in physics that measures the opposition to the flow of electric current, heat, light, sound, or any other form of energy or matter. It is the measure of how much an object, material, or system resists the flow of electric current, heat, light, sound, or any other form of energy or matter.

a) U₂ = 0 V. The lamp (L₂) is short circuited, meaning that there is no resistance between its terminals. As such, the voltage across its terminals must be zero.

b) U₁ = 12 V. Since the generator is providing a constant voltage of 24 V across its terminals, the voltage across the terminals of (L₁) will be half of this, i.e. 12 V. As the lamps are identical, the current I' through the circuit will also be 0.6 A.

c) (L₁) may burn out due to the large amount of current it is carrying. If the current is too high, it may exceed the rated capacity of the lamp and lead to its failure.

d) (L₁) does not burn out because the circuit includes a fuse. The fuse is designed to break the circuit in the event of an excessive current, thus protecting the lamp from burning out. When the fuse blows, the circuit is broken and the lamp will be off.

The Earth's atmosphere is divided into several layers, each with different characteristics that affect the types of wavelengths that are reflected, absorbed, or allowed to pass through to Earth's surface.

The first layer closest to Earth's surface is the troposphere, which contains most of the Earth's weather. This layer is characterized by decreasing temperature with altitude and contains water vapor, carbon dioxide, and other greenhouse gases. These gases absorb and re-emit certain wavelengths of radiation, such as infrared radiation, which are trapped within the atmosphere, leading to the greenhouse effect. This helps to keep the Earth warm, but too much of this effect can lead to global warming and climate change.

The next layer is the stratosphere, which contains the ozone layer. Ozone absorbs harmful ultraviolet radiation from the sun, preventing it from reaching the Earth's surface. This layer allows visible light and some infrared radiation to pass through.

Above the stratosphere is the mesosphere, where most meteoroids burn up upon entering the Earth's atmosphere. This layer absorbs most of the incoming radiation and reflects some of it back into space.

Finally, the thermosphere is the outermost layer of the Earth's atmosphere, where the temperature increases with altitude due to the absorption of high-energy solar radiation. The ionosphere, a sub-layer of the thermosphere, contains ions and free electrons that can reflect and scatter radio waves, making long-range communication possible.

Overall, the characteristics of each atmospheric layer affect the types of wavelengths that are reflected, absorbed, or allowed to pass through to the Earth's surface. The amount of radiation absorbed or reflected by each layer can also affect the Earth's climate and weather patterns.
