current = (voltage) / (resistance) < == the formula (from ohm's law)
current = (5 volts) / (2.5 ohms) < == the work
current = 2 amperes < == the solution
here is the answer calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. then, multiply the area of the base by the height of the cylinder to find the volume.
thermal energy transfer through conduction, conduction involves the direct transfer of heat from one object to another object that is contacted.
thermal energy transfer through convection, convection involves the movement of warm particles.
thermal energy transfer through radiation, radiation involves the movement of electromagnetic waves.
