What causes the centrifugal force effect? chk – Centrifugal Force Caused by Inertia. When you swing an object around on a string or rope, the object will pull outward on the rope. The force you feel is called the centrifugal force and is caused by the inertia of the object, where it seeks to follow […]
Where can a third charge be placed so that?
How can we reduce natural hazards?
How can we reduce natural hazards? Awareness, education, preparedness, and prediction and warning systems can reduce the disruptive impacts of a natural disaster on communities. Mitigation measures such as adoption of zoning, land-use practices, and building codes are needed, however, to prevent or reduce actual damage from hazards. What precautions should we take to prevent […]
What is electrostatic screening length?
What is electrostatic screening length? Within the classical mean-field theories that explain screening and interactions in dilute electrolytes,(1) the Debye length, λD, is the yardstick against which the reach of electrostatic interactions in solution is typically measured. What is screening in cable? The screen is often directly placed over the insulated cores or pairs inside […]
What are three signs of the inflammatory response?
What are three signs of the inflammatory response? What are the signs of inflammation? The four cardinal signs of inflammation are redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor). Redness is caused by the dilation of small blood vessels in the area of injury. Does vitamin D help with inflammation? Beyond its critical […]
What is Fitt formula?
What is Fitt formula? The FITT formula is a formula in which each letter represents a factor for determining how to obtain fitness benefits from physical activity: F=frequency, I=intensity, T=time and T=type. What is time in the Fitt formula? Intensity: refers to the intensity of exercise undertaken or how hard you exercise. Time: refers to […]
Is filming on a plane Illegal?
Is filming on a plane Illegal? For example, American Airlines’ photography policy strictly prohibits “photography or video recording of airline personnel, equipment, or procedures.” United, Delta and Southwest have similar policies. However, even if a passenger films without permission, there is no law against taking video or photographs on a plane. Can you take pictures […]
How do you remember thermodynamic relations?
How do you remember thermodynamic relations? A mnemonic used by students to remember the Maxwell relations (in thermodynamics) is “Good Physicists Have Studied Under Very Fine Teachers”, which helps them remember the order of the variables in the square, in clockwise direction. How do you remember Gibbs free energy? The equation often seen for Gibbs […]
What are the 3 types of scatter plots?
What are the 3 types of scatter plots? There are three types of correlation: positive, negative, and none (no correlation). Positive Correlation: as one variable increases so does the other. Height and shoe size are an example; as one’s height increases so does the shoe size. Negative Correlation: as one variable increases, the other decreases. […]
How does heat transfer from one object to another?
How does heat transfer from one object to another? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]
