4. Perform the experiment
5. Analyze the data
6. Conclusion
So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
Answer:
Explanation:
If H be the heat flowing in time t through an area of A having thickness d
H = k A x ( θ₂ - θ₁ ) t / d , k is thermal conductivity , ( θ₂ - θ₁ ) is temperature difference of walls
putting the given values
= (1.12 x 2.8x 5 x 9 x 16.7 x 60 x 60) / .08
= 1.06 x 10⁸ J .
Answer:
Explanation:
F = Force = 
m = Mass of proton = 
t = Time taken = 
Acceleration is given by
The velocity of the proton is
Answer: When enough __energy__ is added to the substance, the solid reaches its _melting_ point and becomes a liquid
Explanation: since energy is being added the substance changes phase into a liquid .
