Heat can be transmitted by a conductor using conduction and convection method.
<u>Explanation:</u>
Heat energy can be transferred in three ways. In other words, the propagation of heat energy can be done by conduction, convection and radiation. Among these three conduction and convection requires a conducting medium, while radiation does not require any medium for transmitting the heat energy.
Conduction is the form of heat energy transfer where the energy is transmitted through the medium in contact with each other. So the electrons will collide with each other and the medium should be in contact and they should be highly conducting in nature, to perform conduction.
In case of convection, the liquid or gas molecules transfer the thermal energy from one point to another. No contact between the medium is required. It passes through the flow of gas or liquids. Thus, conduction and convection are the two methods by which heat can be transmitted by a conductor.
Force can be calculated by the product of mass and the acceleration of the object in motion. Acceleration is the change of velocity per change in time. The expression would be:
F = ma
where
a = Δv/Δt
The object is from rest and time 0. Acceleration would reduce to:
a = v/t
F = m(v/t)
2000 = 100 (v / 0.3)
v = 6 m/s -------> OPTION 1
