Answer:
7.9 kilometers per second
Explanation:
Answer:
a. 51.84Kj
b. 2808.99 W/m^2
c. 11.75%
Explanation:
Amount of heat this resistor dissipates during a 24-hour period
= amount of power dissipated * time
= 0.6 * 24 = 14.4 Watt hour
(Note 3.6Watt hour = 1Kj )
=14.4*3.6 = 51.84Kj
Heat flux = amount of power dissipated/ surface area
surface area = area of the two circular end + area of the curve surface

= 2.136 *10^-4 
Heat flux =
= 2808.99 
fraction of heat dissipated from the top and bottom surface

=11.75%
1.Only suitable for dc
2.more expensive than moving iron type
3. Easily damaged
