What does the Bobo doll experiment prove?
What does the Bobo doll experiment prove? Bobo doll experiment, groundbreaking study on aggression led by psychologist Albert Bandura that demonstrated that children are able to learn through the observation of adult behaviour. … What two things did Bandura conclude? Bandura concluded that children learn two things from observing an aggressive model-how to perform the […]
Which machine motion is the most dangerous?
Which machine motion is the most dangerous? Transverse motion (movement in a straight, continuous line) creates a hazard because a worker may be struck or caught in a pinch or shear point by the moving part. Reciprocating motions. Warning: Exposure to rotating shafts is the most dangerous machine safeguarding hazard. What are the 4 types […]

Can you reflect sound waves?
Can you reflect sound waves? Reflection of sound waves also leads to echoes. Echoes are different than reverberations. Echoes occur when a reflected sound wave reaches the ear more than 0.1 seconds after the original sound wave was heard. There will be an echo instead of a reverberation. Do light waves travel faster than sound […]

What happens when a person is exposed to EM waves?
What happens when a person is exposed to EM waves? Exposure to electromagnetic fields is not a new phenomenon. When electric fields act on conductive materials, they influence the distribution of electric charges at their surface. They cause current to flow through the body to the ground. Low-frequency magnetic fields induce circulating currents within the […]
Is graphene harmful to the human body?
Is graphene harmful to the human body? At the level of the whole body, the authors indicate that there are two main safety factors to consider regarding exposure to CNTs and graphene. The first is their ability to generate a response by the body’s immune system; the second is their ability to cause inflammation and […]

What are the two methods of sensing incoming engine air flow?
What are the two methods of sensing incoming engine air flow? There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with additional sensors and inputs, an engine’s ECU can determine the […]
