Answer:
ig so it's already heated
<h2>Activities illustrates the Nature of a Dialectical Process</h2>
Dialectical method is at center a conversation among two or more characters carrying diverse localities of opinion regarding a topic but hoping to build the fact by reasoned disputes. Dialectic relates a discussion but cleft of biased components such as passionate plea and the recent derogatory knowledge of eloquence.
It can be compared with the dialectic method where one faction of the communication informs the another. Logic is alternatively identified as lesser reasoning, as objected to superior thought or commentary.

Answer:
26.8 %
Explanation:
TH = 100°C = 100 + 273 = 373 K
Tc = 0°C = 273 K
The efficiency of the heat engine is given by
η = 0.268
η = 26.8 %
Thus, the efficiency of the heat engine is 26.8 %.
Answer:
25.06s
Explanation:
Remaining part of the question.
(A large stone sphere has a mass of 8200 kg and a radius of 90 cm and floats with nearly zero friction on a thin layer of pressurized water.)
Solution:
F = 60N
r = 90cm = 0.9m
M = 8200kg
Moment of inertia for a sphere (I) = ⅖mr²
I = ⅖ * m * r²
I = ⅖ * 8200 * (0.9)²
I = 0.4 * 8200 * 0.81
I = 2656.8 kgm²
Torque (T) = Iα
but T = Fr
Equating both equations,
Iα = Fr
α = Fr / I
α = (60 * 0.9) / 2656.8
α = 0.020rad/s²
The time it will take her to rotate the sphere,
Θ = w₀t + ½αt²
Angular displacement for one revolution is 2Π rads..
θ = 2π rads
2π = 0 + ½ * 0.02 * t²
(w₀ is equal to zero since sphere is at rest)
2π = ½ * 0.02 * t²
6.284 = 0.01 t²
t² =6.284 / 0.01
t² = 628.4
t = √(628.4)
t = 25.06s
