A researcher investigated whether job applicants with popular (i.e. common) names are viewed more favorably than equally qualified applicants with less popular (i.e. uncommon) names. Participants in one group read resumes of job applicants with popular (i.e. common) names, while participants in the other group read the same resumes of the same job applicants but with unpopular (i.e. uncommon) names. The results showed that the differences in the evaluations of the applicants by the two groups were not significant at the .001 level
The researcher did not find strong evidence to support the idea that job applicants with popular names are viewed more favorably than equally qualified applicants with less popular names.
What factors plan an important role in the hiring process for a job?It sounds like the researcher conducted an experiment to investigate whether job applicants with popular names are viewed more favorably than equally qualified applicants with less popular names.

What is the cost per month to operate an A.C. 10hours per day whose power is 3kW and 1KWH cost 79francs
The cost of operation for an A.C for 10 hours per day for a month will be 71,100 francs.
What is Power?Power is the amount of energy transferred or converted per unit time. The unit of power is the watt, equal to one joule per second. Power is a scalar quantity.
Cost of operation for 10 hours a day;
Daily consumption = 3kW x 10 hours
Daily Consumption = 30kW
Since 1kWH = 79 francs;
Daily consumption amount = 30 x 79 francs
Daily consumption amount = 2,370 francs
Therefore, the monthly consumption (using 30days) will be;
2,370 francs x 30 = 71,100 francs
In conclusion, 71,100 francs will be spent in a month (30 days) to run the 3kW rated A.C for 10 hours a day at 1kWH.

Answer:
Normal force is the force exerted on an object that is in contact with another non-moving object. Force is push and pull
Ex: When a book rests on a surface (like a table), the table is exerting a force on the book in order to support the weight of it.
Answer:
Normal Force is a contact force. When 2 objects are touching each other, they are in contact. Like when a cup is sitting on a table they are in contact cause the table has to hold the force of the cup up on the table.

The centripetal acceleration of the plane is 0.255 g.
What is centripetal acceleration?
centripetal acceleration is the rate at which a body moves through a circle. Due to the fact that velocity is a vector quantity (i.e., it has both a magnitude, the speed, and a direction), when a body travels in a circle, its direction is continually changing, which causes a change in velocity, which results in an acceleration. The circle's Centre is where the acceleration is pointed radially.
Since we are given the tension in the cable and the angle of inclination, we can use trigonometry to find the vertical and horizontal components of tension.
Tsinθ = mg
Tcosθ = mv²/r
where θ = 35°, v = 180 km/h = 50 m/s, r = 1000 m, and m = 1000 kg.
Solving for Tsinθ and Tcosθ, we get:
Tsinθ = mg = (1000 kg)(9.81 m/s²) = 9810 N
Tcosθ = mv²/r = (1000 kg)(50 m/s)²/(1000 m) = 2500 N
Now we can use the horizontal and vertical components of tension to find the centripetal acceleration:
Tcosθ = ma
a = Tcosθ/m = (2500 N)/(1000 kg) = 2.5 m/s²
To express this acceleration in terms of g, we divide by the acceleration due to gravity:
a/g = 2.5 m/s² / 9.81 m/s² = 0.255
Therefore, the centripetal acceleration of the plane is 0.255 g.

The boat’s resultant velocity is v = 31.0 m/s, and the direction of the boat is 23.2 degrees north of east.
A resultant velocity is calculated using the formula below.
Vm equals Sum Sqrt(Vxi2 + VYj2)
where Vm is the resulting magnitude of velocity.
All x-component velocities are denoted by the letters Vxi.
The y-component of all velocities is called Vyj.
Add all of the values for the x-components together, square that number to get the magnitude of the resultant velocity. Add this to the earlier value after doing the same operation for the y-components. Finally, to determine the magnitude, square the result.
Tan-1 (Vx/Vy) = Va

A particle carrying a charge of 0.50 µC enters a magnetic field of strength 0.045 T, with a velocity of 350 m/s.
The velocity is perpendicular to the magnetic field. What is the magnetic force acting on the charged particle?
Answer:
Explanation:
The magnetic force (F) acting on a charged particle moving in a magnetic field is given by the equation:
F = qvBsinθ
where q is the charge of the particle, v is the velocity of the particle, B is the magnetic field strength, and θ is the angle between the velocity of the particle and the direction of the magnetic field.
In this case, the charge of the particle is 0.50 µC, the velocity is 350 m/s, and the magnetic field strength is 0.045 T. Since the velocity of the particle is perpendicular to the magnetic field, θ = 90°. Therefore, we can substitute the values into the equation and solve for the magnetic force:
F = qvBsinθ
F = (0.50 x 10^-6 C)(350 m/s)(0.045 T)(sin 90°)
F = 0.0084375 N
Therefore, the magnetic force acting on the charged particle is 0.0084375 N.

The EMF induced in a single wire loop with an area of 0.0940 m² is in a uniform magnetic field which has an initial value of 3.80 T, is perpendicular to the plane of the loop, and decreases at a constant rate of 0.190 T = 0.34 V. And the current induced in the loop = 0.57 A.
The EMF inducedInduced electromotive force or induced emf is the potential difference at the ends of the coil which will produce an induced electric current.
An induced electric current appears as long as there is a change in magnetic flux.
The equation is:
ε = d∅/dt
We have,
The area of the loop = 0.0940m²
The change in magnetic field with time = (3.80 T - 0.190 T) = 3.61 T
So, the EMF induced:
ε = d∅/dt
= {(0.0940m²) (3.61)} / 1
