How are conditions, convictions, and radiation different

When two objects are in direct contact with each other, there will be an exchange of heat from the hotter object to the colder one, which is because of conduction. Further, the objects which allow heat to movement effortlessly through them are called conductors.  

Convection infers the type of heat exchange, by genuine movement of matter, that happens just in fluids. Fluids suggests any substance, whose particles move uninhibitedly starting with one place then onto the next, for example, liquid and gases.  

The heat transfer system in which no medium is required is called radiation. It alludes to the movement of heat in waves, as it needn't bother with atoms to movement through. The object requires not be in direct contact with each other to transmit heat. At whatever point you feel heat without touching the object, it is a direct result of radiation.

iron would move it is magnetic there is a mag field around the current in the wire

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
