The answer to this question is C
Net convective heat transfer loss rate (gnet)
Gnet = 2h, A (Ts - T∞)
=2(4.51) (0.001) (25)
Gnet = 0.2250 W.
There are two types of convection: natural convection and forced convection. Natural convection is caused by differences in the density of liquids due to differences in temperature (eg "hot air rises"). Global atmospheric circulation and local weather phenomena (including wind) are due to convective heat transfer.
Newton's Law of Cooling is a widely used equation for calculating both forced and natural net convective. The formula for Newton's Law of Cooling is Q = h A ΔT. Equation parameters and their typical US and SI.

Answer: current = 10.25A
Explanation:
Toward = 240w
Alarm clock = 30w
Tanning bed = 720w
4 60 watts bulb = 60 * 4 = 240w
Total power = 240 + 30 + 720 + 240 = 1230w
Voltage = 120v
Recall that Power = current * voltage
1230 = current * 120
current = 1230/120 = 10.25A
Answer:
The answer is given as follows,
Explanation:
Gold large-sized weight 100 g < M < 250g
50 g < Magenta small-sized weight < 100g
100g < Blue medium-sized weight < 250g
Hence,
100g < Blue medium-sized weight < 250g
50 g < Magenta small-sized weight < 100g
100 g < Gold large-sized weight < 250g.
