False. Magnetic interactions can occur even when the interacting objects are not touching. Magnetic fields can exert forces on objects at a distance, such as between a magnet and a piece of metal.
The answer to this question is no. Radiation can occur when objects are not touching
Two objects must be touching and it has to transfer heat
Neutral objects are neither attracted nor repelled by positively or negatively charged objects. This is because neutral objects have an equal number of positive and negative charges, resulting in no net charge and hence no interaction with charged objects.
Heat can be transferred by radiation even if the objects are not touching. Radiation is a form of energy transfer that can occur through empty space, so it does not require direct contact between objects. Objects can exchange heat through radiation by emitting and absorbing electromagnetic waves.
No, conduction requires physical contact between objects to transfer heat. Without direct contact, conduction cannot occur.
The two categories of forces are contact forces, which occur when two objects are physically touching, and non-contact forces, which act between objects that are not in direct physical contact.
Touching forces, also known as contact forces, are interactions that occur when two objects physically touch each other. They can include forces like friction, normal force, tension, and air resistance. These forces are important in understanding how objects behave and move in the physical world.
convection and radiation heat transfer bot occur without either object being in direct contact with each other.
No, conduction can occur between objects without them needing to be in direct contact. Heat conduction can happen through a material medium or in the form of radiation, where energy is transferred through electromagnetic waves.
True. Charge can be transferred between objects without the need for them to be in direct contact with each other. This can occur through processes such as induction or through the movement of charged particles.
In accordance with Newton's third law, Steve and Gretchen are touching each other. One may initiate the touch, but the physical interaction can't occur without contact between both Steve and Gretchen. Indeed, you cannot touch without being touched!
