A nuclear reaction is the perfect place to use <u> E = mc² </u>.
9.00 x 10¹³ = (m) (3 x 10⁸)²
Divide each side by (3 x 10⁸)² : m = (9 x 10¹³) / (3 x 10⁸)²
m = (9 x 10¹³) / (9 x 10¹⁶) = <em>0.001 kg</em>
Now, take several steps back, and look at what you've been working with:
You just showed that 1 gram of matter, when completely converted to energy,
produces the energy for a 100-watt light bulb to run for 28,519 years !
Correct answer is option C.
Remaining liquid over a wide temperature range
Other options are invalid.
Answer:
Themal energy is the best answer from you
Answer:
Wood Resistance = 0.18 m².°C/W
Explanation:
The formula for heat flow in terms of thermal resistance is:
Q/A = ΔT/R
R = AΔT/Q
where,
R = Total Resistance = Resistance of Concrete + Resistance of wood = Resistance of wood + 0.26 m².°C/W
A = Surface Area of Wall = 3.2 m x 4.7 m = 15.04 m²
ΔT = Difference in temperature = 16°C - 2°C = 14°C
Q = Heat Flow = 476 Watt
Therefore,
0.26 m².°C/W + Wood Resistance = (15.04 m²)(14°C)/(476 W)
Wood Resistance = 0.44 m².°C/W - 0.26 m².°C/W
<u>Wood Resistance = 0.18 m².°C/W</u>
Answer:
the answer is kinetic energy
