To pass a bicyclist traveling in the same direction on a two-lane road without bicycle lanes, you should slow down and wait until there is no traffic approaching, then pass the bicyclist leaving him or her sufficient space.

A bike lane is a section of the road that has been marked with pavement markings, signage, and striping specifically for the preferential or exclusive use of cyclists. With predictable behaviour and movements between cyclists and motorists, bike lanes allow cyclists to travel at their preferred speed without being hindered by the current traffic situation.

A bike lane differs from a cycle track in that it lacks any physical barriers (bollards, medians, raised curbs, etc.) that prevent motorised traffic from encroaching on it. When there is no parking, traditional bike lanes run along the curbside, next to parked cars on the right side of the street, or on the left side of the street in certain circumstances.

When performing the calculations and layout prior to bending/installing the conduit, the tools that an electrical worker should have include a calculator and a mathematical formula to determine the amount of conduit that would be needed.

In addition, the electrical worker must have a conduit bender with various bending shoes to fit the conduit's dimensions, a hacksaw or a reciprocating saw, a reaming tool to remove burrs and sharp edges after cutting, and a tape measure. To be able to carry out the calculations needed for conduit bending, it is crucial that you are well familiar with basic mathematics, especially geometry and trigonometry, and you can operate a scientific calculator.

Most conduit-bending tables use these calculations and would help to learn them as they are fundamental to becoming an experienced conduit bender. Measure and mark the bend mark. Cut the conduit. Ream the conduit to remove burrs. Set the bender on the floor. Insert the conduit into the bender. Follow the bending chart to make the desired bend angle. Set the second bend angle (if necessary).Reverse the bender and bend the other side of the conduit.

Using the Newton's second law of motion we will see that the acceleration is  0.0875 m/s^2.

The acceleration of a vehicle is determined by the force acting on it and its mass, as described by Newton's second law of motion:

F = m * a

where F is the force acting on the object, m is the mass of the object, and a is the resulting acceleration.

In this case, the force acting on the vehicle is 0.07 N, and the mass of the vehicle is 0.8 kg. Substituting these values into the equation above, we get:

0.07 N = 0.8 kg * a

Solving for a, we get:

a = 0.07 N / 0.8 kg

a = 0.0875 m/s^2

Therefore, the acceleration of the 0.8 kg vehicle powered by 0.07 N of force is 0.0875 m/s^2.

The nitrogen compressor in the chemical plant adiabatically compresses 600 ft3/s of N2 from 15 psia and 77°F to 300 psia and 900°F. Adiabatic compression means that no heat is exchanged with the surroundings during the process.

After compression, the nitrogen passes through a heat exchanger, where it is cooled at constant pressure. The outlet temperature is given as 150°F.

To analyze this process, we can use the ideal gas law and the specific heat capacity at constant pressure (Cp) for nitrogen. The ideal gas law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

First, convert the temperatures from Fahrenheit to Kelvin:

Initial temperature = (77°F + 459.67)°R = 536.67°R
Final temperature = (150°F + 459.67)°R = 609.67°R

Next, determine the number of moles of nitrogen using the given volume and pressure at the initial condition:

n = PV / RT
n = (15 psia)(600 ft3/s) / (10.73 psia*ft3/R)(536.67°R)
n ≈ 13.7 mol/s

Now, we can calculate the final volume using the final pressure and the number of moles:

V = nRT / P
V = (13.7 mol/s)(10.73 psia*ft3/R)(609.67°R) / 300 psia
V ≈ 408 ft3/s

In summary, the nitrogen compressor adiabatically compresses 600 ft3/s of N2 from 15 psia and 77°F to 300 psia and 900°F. Then, in the heat exchanger, the nitrogen is cooled at constant pressure to an outlet temperature of 150°F. The final volume of nitrogen is approximately 408 ft3/s.

When a dielectric is inserted into a capacitor connected to a battery, the energy stored in the capacitor increases. This is because the electric field between the plates decreases due to the presence of the dielectric, which leads to an increase in capacitance and an increase in energy stored in the capacitor.

The capacitance is defined as the ability of a capacitor to store energy in the form of an electric charge, and it is directly proportional to the distance between the plates and inversely proportional to the dielectric constant of the medium between the plates.

The work done in the process of inserting a dielectric into a capacitor is given by the equation W = Fd, where W is the work done, F is the force required to insert the dielectric, and d is the distance over which the force is applied. The force required to insert the dielectric is proportional to the change in electric field between the plates, which in turn is proportional to the dielectric constant of the medium.

The energy stored in a capacitor connected to a battery increases when a dielectric is inserted, and the work done in the process depends on the dielectric constant of the medium.

In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.

Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.

Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.

In the steady state total volume going out will be equal to total volume coming in , and

total salt coming in = total salt going out

Total volume coming in per minute = 2000 + 2 x 10³ x 60

= 122000 L .

Total salt coming in per minute = 1200 x 2000 + 20  x 2 x 10³ x 60

= 2400000 + 2400000 mg

= 4800000 mg

volume of water going out per minute = 122000 L

Total salt going out  per minute = 4800000 mg

concentration of water going out = 4800000 / 122000

= 39.344 mg / L
