Limiting contact between gamma rays and healthy tissue is important because gamma rays are high-energy ionizing radiation that can damage healthy cells and cause mutations, increasing the risk of cancer and other adverse health effects. Shielding and focusing gamma rays to target specific areas of the body during radiation therapy can help minimize damage to surrounding healthy tissue.
What else can I help you with?
What are the factors on which limiting friction depends?
Limiting friction depends on factors such as the nature of the surfaces in contact, the applied force pressing the surfaces together, and the presence of any lubricants between the surfaces. The roughness of the surfaces, the temperature, and the contact area also influence limiting friction.
State laws of limiting friction?
1. the direction of force of friction is always opposite to the direction of motion.. 2. the magnitude of limiting friction depends upon the nature and state of polish of the two surfaces in contact and acts tangentially to the interface between them.. 3. the magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.. 4. the magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same..
What are the examples of limiting friction?
If limiting friction is the same as static friction, then I have an answer, because static friction means that the objects in contact do not move. For example, if you place a box on the table, it does not move, as there is static friction between the box and the table.
Is gravity considered a contact force?
Gravity is not considered a contact force because it acts at a distance, without physical contact between the objects. Contact forces, such as friction or tension, require direct contact between objects for the force to be exerted.
What is it called when friction stops something from moving?
The frictional force needed to just stop something from moving is called limiting friction, and the object is said to be in limiting equilibrium.

What physical feature might have limited contact between India and China?
The Himalaya Mountains. That should answer your question.
Why was Columbus' contact with America significant?
Because Columbus' voyage of finding the New World was an failed attempt so instead he found America (which was the New World) and it led to the permanent contact between America and Europe...so that is why the contact is significant between the two.
When force is applied to an object but does not cause the object to move?
That will happen if the force applied is less than the limiting value of the friction between the object and the surface that it is in contact with.
What was japans and China's policy of limiting foreign contact called?
Isolationism
What is limiting value of friction?
The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.

Some countries are reluctant to have contact with other countries. What do these countries lose by limiting contact with other countries?
by providing them with foreign aid.

Heat transfer between two substances that are in contact is called?
the answer is conduction because it transfers heat between two substances that are in contact.
