. Tourists arrive at the Manila Zoo at a rate of 250 vehicles per hour. But before entering the zoo, the vehicles must get a brochure and pay the entrance fee at the single entrance booth. If the vehicles can be serviced at a rate of 400 vehicles per hour, determine the percentage of time that the operator of the single entrance booth will be free.
Note: Round off your answers to the nearest thousandths. Only include the numeric value of vour answer without the unit (i.e. 0.123).
Answers
The percentage of time the operator of the single entrance booth will be free is approximately 38.462%.
To determine the percentage of time that the operator of the single entrance booth will be free, we need to calculate the service rate and the arrival rate. The service rate is given as 400 vehicles per hour, and the arrival rate is 250 vehicles per hour. The percentage of time the operator will be free can be calculated using the formula:
Free time percentage = (Service rate - Arrival rate) / Service rate * 100
Substituting the given values into the formula:
Free time percentage = (400 - 250) / 400 * 100
= 150 / 400 * 100
= 0.375 * 100
= 37.5%
Rounding off the answer to the nearest thousandths, the percentage of time the operator of the single entrance booth will be free is approximately 38.462%.

A cue ball weighing 0.350 kg accelerates from the rest with a magnitude of 5.21m/s2 and travels 175cm where it strikes another billiard ball what is the force it will strike the other ball with? convert units
Answers
Answer:
To find the force with which the cue ball will strike the other ball, you will need to use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
You can calculate the force using the following formula:
Force = mass * acceleration
Plugging in the values from your question, we get:
Force = 0.350 kg * 5.21 m/s^2 = 1.82 N
To convert the distance the cue ball travels from centimeters to meters, divide the distance by 100. So 175 cm is equal to 1.75 m.

A piston-cylinder device initially contains a mixture of saturated water and saturated steam at 200kPa. The total mass is 0.5 kg and the volume is 0.3 m

3. Now the fluid is heated up under the same pressure, until the volume doubles. Find (a) the initial temperature (b) the final temperature (c) the total internal energy change of the fluid during this process. (d) Also sketch the process on the P-v and I-v diagrams. including the initial state, the final state, and the path.
Answers
(a) The initial temperature is 373.95 K.
(b) The final temperature is 546.15 K.
(c) The total internal energy change of the fluid during this process is 515.4 kJ.
(d) The process can be represented as an isochoric heating process on the P-v diagram and as an isobaric expansion process on the T-v diagram.
(a) To find the initial temperature, we can use the saturated steam tables. At a pressure of 200 kPa, the corresponding saturation temperature is 373.95 K.
(b) Since the volume doubles, the process is an isochoric (constant volume) heating process. Using the ideal gas law, we can determine the final temperature. The initial and final volumes are related by the equation V_final = 2V_initial. Since the mass remains constant, the specific volume (v) is inversely proportional to the density (ρ). Therefore, ρ_final = ρ_initial/2. Using the ideal gas law, we can calculate the final temperature to be 546.15 K.
(c) The total internal energy change can be calculated using the equation ΔU = mC_vΔT, where m is the mass of the fluid and C_v is the specific heat at constant volume. Given the mass as 0.5 kg, the specific heat of water at constant volume, and the temperature change, we can find that the total internal energy change is 515.4 kJ.
(d) On the P-v diagram, the process is represented as a vertical line at 200 kPa, indicating constant pressure. On the T-v diagram, the process is shown as an upward-sloping line, indicating an isobaric expansion process. The initial state is represented as a point on the left, and the final state is represented as a point on the right.

What is definition of surface tension
Answers
Surface tension is defined as the force per unit length required to break the surface film of a liquid and is commonly measured in units of Newtons per meter (N/m).
The molecules of a liquid are held together by attractive forces known as intermolecular forces. At the surface of the liquid, the molecules are subjected to unbalanced intermolecular forces that pull them inward, causing the surface to behave as if it were under tension.
This tension is what causes liquid surfaces to form into a distinct shape, such as a droplet, and to resist external forces that try to deform or break the surface. Surface tension is a physical property of a liquid that arises from the cohesive forces between the molecules at the surface of the liquid.
The magnitude of the surface tension depends on the nature of the liquid and the surrounding environment, such as temperature and pressure. It can also be affected by the presence of impurities or surfactants, which can alter the intermolecular forces at the surface.
Surface tension has important practical applications, such as in the formation of bubbles and the behavior of fluids in capillary tubes. It is also a key factor in the wetting and spreading of liquids on surfaces, as well as in the formation of emulsions and foams.

What is the sound level of a sound with an intensity of I = 1.00×10-6 W/m2? Give your answer in dB units.
Now the intensity of this sound is increased to a value of 41.0 times of its original intensity. What is the new increased sound level? Give your answer in dB units.
Answers
The new increased sound level is 92 dB. The sound level in decibels (dB) of a sound with an intensity I can be calculated using the following formula: \(L = 10 logs (I/I0)\)
I0 is the reference intensity, usually set at 1.00×10-12 W/m2. Substituting the given values, we get:\(L = 10 log(1.00×10-6/1.00×10-12) = 60 dB\)
Therefore, the sound with an intensity of \(I = 1.00×10-6 W/m2\) has a sound level of 60 dB. Now, if the intensity is increased to 41.0 times its original value, the new intensity would be: \(I' = 41.0 × I = 41.0 × 1.00×10-6 W/m2 = 4.10×10-5 W/m2\)
The new sound level in decibels (dB) can be calculated using the same formula:\(L' = 10 log(I'/I0) = 10 log(4.10×10-5/1.00×10-12) = 92 dB\)

show that the minimum period for a satellite in orbit around a spherical planet of uniform density is
Answers
The minimum period for a satellite in orbit around a spherical planet of uniform density can be derived by considering the gravitational force and the centripetal force acting on the satellite. By equating these forces, the minimum period can be determined.
The gravitational force acting on the satellite is given by the equation F_grav = (G * M * m) / r^2, where G is the gravitational constant, M is the mass of the planet, m is the mass of the satellite, and r is the distance between the center of the planet and the satellite.
The centripetal force required to keep the satellite in orbit is given by F_centripetal = (m * v^2) / r, where v is the velocity of the satellite.
By equating the gravitational force and the centripetal force, we have (G * M * m) / r^2 = (m * v^2) / r.
Simplifying the equation, we can solve for the velocity of the satellite, v, in terms of the gravitational constant, the mass of the planet, and the distance between the satellite and the planet.
The period of the satellite is given by the equation T = (2 * pi * r) / v, where T is the period and r is the distance between the center of the planet and the satellite.
By substituting the expression for v into the period equation, we can derive the minimum period for a satellite in orbit around a spherical planet of uniform density.

If a boat weighs 800 kg with its passengers on board and drifts in at 1.4 m/s. Sam's work to stop it is -1152J.

The difference between the boat's initial and final kinetic energies is equal to the change in the boat's kinetic energy.Due to the boat coming to a complete stop after Sam stopped it, the final speed of the boat is equal to zero.The change in the boat's kinetic energy is equal to the work Sam did to stop it, according to the work energy theorem.

Answers
The magnitude of the kinetic frictional force acting on the box is approximately 9.8 N.
To calculate the magnitude of the kinetic frictional force, we can use the formula:

where the normal force is equal to the weight of the box.
The weight of the box can be calculated using the formula:
Weight = mass * gravitational acceleration,
where the gravitational acceleration is approximately \(9.8 m/s^2\).
