Answer:
a) Displacement of the object from t = 0 to t = 3 is 1.5 m
b) Distance of the object from t = 0 to t = 3 is 1.83 m
Explanation:
Velocity, v(t) = t² - 3t + 2
a) Displacement is given by integral of v(t) from 0 to 3.
b) t² - 3t + 2 = (t-1)(t-2)
Between 1 and 2, t² - 3t + 2 is negative
So we can write t² - 3t + 2 as -(t² - 3t + 2)
Distance traveled
It would decrease because the frequency is decreasing
Given:
= 323 K
= 293 K
specific heat of aluminium,
specific heat of water,
Formula Used:
Q = m
Solution:
Let the temperature at equilibrium be ' ' K
Now at equilibrium, using the given formula:
Temperature at equilibrium, = 295.513 K
Now, change in entropy(in J/K) is given by:
Q = m
= 12094.28 cal
Now,
= 40.93 cal/K = 9.78 J/K
Therefore change in entropy is given by:
Answer: The time of motion of the stream of water is calculated as follows;
X = Vₓt
Explanation:
Answer:
thermodynamics
Explanation:
The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.
