Answer: The block of 0.4 Kg travel the same distance that the block of
0.2 Kg
Explanation: Considering the second newton law, we have the following
F= m*a
F= P*sin (θ) where θ is the angle for the incline
so mg sin (θ)= m*a
a=g sin(θ)
both block have the same acceleration in the inclined plane so travel the same distance independent of its mass.
F = ma
20 N = 20kg * a
a = 20 N /20kg
acceleration = 1 N/kg or 1 m/s²
The standard gibbs free energy of formation of <u>i2 (s)</u> is zero.
<h3 /><h3>Definition of gibbs free energy</h3>
The maximum amount of work that can be accomplished by a thermodynamically closed system at constant temperature and pressure can be calculated using the Gibbs free energy, a thermodynamic potential. Furthermore, it offers a prerequisite for any processes, like chemical reactions, that might take place in such circumstances.
The Gibbs free energy change (measured in joules in SI) is the maximum non-expansion work that can be extracted from a closed system (one that can exchange heat & work with its surroundings but not matter) at fixed temperature & pressure. Only a completely reversible mechanism is able to reach this maximum.

Answer:
0.079 m or 79 mm
Explanation:
Using the equation of motion
v = √(2as)
Where v is the velocity
a is acceleration = 1400m/s²
s is the distance = 0.55 mm = 0.00055m
Therefore
= √(2 × 1400m/s² × 0.00055 m) = 1.54 m/s
Therefore; initial velocity = 1.54 m/s
Then we use the equation of motion s = v² / 2g
Take g = 9.8 m/s²
Therefore
= (1.54m/s)² / 19.6 m/s²
= 0.079 m or 79 mm
Answer:
23895.05 Pa
Explanation:
V = 0.03 m³
mass, m = 4 g
Temperature, T = 388 K
Let P be the pressure.
number of moles, n = 4 / 18 = 0.22
Use ideal gas equation
PV = n RT
P x 0.03 = 0.22 x 8.314 x 388
P = 23895.05 Pa
Thus, the pressure is 23895.05 Pa.
