The wall separating Henri from his manager made it hard to hear what his manager was saying, the wall is an example of a physical barrier.
Physical barrier is the environmental and natural condition that act as a barrier in communication in sending message from sender to receiver.
Organizational environment or interior workspace design problems, technological problems and noise are the parts of physical barriers.Surroundings, distance between people, time differences and faulty communication methods are factors that can create a physical barrier. Managers must quickly identify these factors to address their negative effects on productivity.Therefore the wall between Henri and his manager acts as a physics barrier which made it hard to hear what his manager is saying.

Problem 12.41 9 of 9 Review A 50 g mass rotates in a vertical plane--call it the xy-plane with the y-axis pointing up--at the end of a 75-cm-long, massless, rigid rod. The other end of the rod is attached to a frictionless pivot at the origin. Part A What is the gravitational torque about the pivot when the mass is 60° above the +x-axis? Give your answer using unit vectors. Express your answer in newton-meters. Enter components of torque, separated by comma. IVO AE ? Tx, Ty,Tz = N·m Submit Request Answer
The value of gravitational torque after solving the expression will be equal to -0.18375 N.mz.
What is Torque?The rotating equivalent of a force in physics or mechanics is called torque. Depending on the topic matter, it may also be referred to as the moment, point in time of force, rotating force, or turning effect. It symbolizes a force's capacity to cause a change inside the bodies natural rotational motion.
As per the given information in the question,
Mass, m = 50 g
Length, l = 75 cm
Gravitational force, [tex]\vec F[/tex] = -mgy
Then, the position vector of the particle will be,
[tex]\vec \tau[/tex] = l(cos 60° x + sin 60° y) × (-mgz)
= -0.18375 N.mz
Therefore,
[tex]\tau_x, \tau_y,\tau_z=0, 0, -0.18375[/tex]

a. What are the defects of simple cell?
a block is pulled along a surface of negligible friction by a spring scale that exerts a force f on the block. the mass of the block is 4kg, and the spring scale reads 10n. which of the following free-body diagrams can be used to show the magnitude and direction of all the forces exerted on the block as it is pulled along the surface?
The correct free-body diagram is the one shown in option C
What is the correct free-body diagram?We know that the free-body diagram could be used to identify the forces that are acting on an object. We know that the normal force that acts on an object must be equal to the weight of the object and this is represented as lines of equal length on the free-body diagram.
We can now see that the correct free-body diagram is one in which the magnitude of the force weight and the normal force is the same. Now the force on the spring would be shown as the forward force.
