Answer:
Using the log combination rules to reduce the famous Sakur-Tetrode equation, The change in entropy is given as:
∆S = NK*ln(V"V$/V").
Where V"V$ is final Volume (Vf) after constraint's removal,
V" is Initial Volume (Vi) before constraint's removal.
Temperature (T) is constant, Internal Energy, U is constant, N and K have their usual notations
Explanation:
Given in the question, the container is an adiabatic container.
For an adiabatic contain, it does not permit heat to the environment due to its stiff walls. This implies that the Internal Energy, U is kept constant(Q = U). The temperature is also constant (Isothermal). Thus, the famous Sakur-Tetrode equation will reduce to ∆S = NK* In(Vf/Vi).
Vf is the volume after the constraint is removed(Vf = V"V$). Vi is the volume occupied before the constraint is removed (Vi = V")
Answer: it is bad for you and can cause some crazy brain dammage and this could potentially end you life because it is harmful :p
Answer:
The car would travel after applying brakes is, d = 14.53 m
Explanation:
Given that,
The time taken to apply brakes fully is, t = 0.5 s
The velocity of the car, v = 29.06 m/s
The distance traveled by the car in 0.5 s, d = ?
The relation between the velocity, displacement, and time is given by the formula
d = v x t m
Substituting the values in the above equation,
d = 29.06 m/s x 0.5 s
= 14.53 m
Therefore, the car would travel after applying brakes is, d = 14.53 m
Answer:
Differences are listed below:
Explanation:
Weight: Plastic can weigh appreciably much less than than metal.A plastic part weighs approximately one-sixth of the same part in steel.
Chemical resistance:Plastic are much less likely to suffer chemical attack and don not corrode.
Machinability: Plastic are much more easier to cut through than metal.
Product life: The life span for plastic is longer than of the metals in many applications.
Cost: The cost of plastic raw materials is appreciably less than of the metals.
Heat: Plastic are less heat resistive than metals.
Ultraviolet light can degrade the plastics soon.
Strength: Metal provides more strength than the plastic.
Answer:
F=50kg
D=5m
W=FD
therefore work done is 250Nm
