Answer : 29.7 mL are in a fluid ounce based on this data.
Explanation :
As we are given that 300 mL and 10.1 oz are equivalent. That means,
300 mL = 10.1 oz
or,
10.1 oz = 300 mL
Now we have to determine the volume of fluid in milliliters.
As, 10.1 oz of fluid = 300 mL
So, 1 oz of fluid =
= 29.7 mL
Therefore, 29.7 mL are in a fluid ounce based on this data.
Answer:
193.4 J/K
Explanation:
For a closed system, the entropy is given as the natural logarithm of microstates.
The number of particles ( grains of sand ) N = 28
The number of boxes ( compartments ) M = 1000
Entropy is the logarithm of number of microstates
But the number of microstates is given by
Answer:
2.43J
Explanation:
Given parameters:
Mass of the arrow = 0.155kg
Velocity = 31.4m /s
Unknown:
Kinetic energy when it leaves the bow = ?
Solution:
The kinetic energy of a body is the energy in motion of the body;
it can be derived using the expression below:
K.E = m v²
m is the mass
v is the velocity
Solve for K.E;
K.E = x 0.155 x 31.4 = 2.43J
Answer:
(a) Elongation of rod = 0.19732 mm
(b) Change in diameter = 0.00651 mm
Explanation:
Circular area at end of steel rod = pi * diameter^2 / 4
Area = 3.801 * 10^(-4) meter squared
Stress = force / area
Stress = 75000 / (3.801 * 10^-4)
Stress = 197316495 Pa OR 0.197 GPa
Modulus of elasticity = stress / strain
200 = 0.19732 / Strain
Strain = 0.0009866 (longitudinal)
(a) Strain = change in length / initial length
0.0009866 = Elongation of rod / 200
Elongation of rod = 0.19732 mm
(b) Poisson ratio = lateral strain / longitudinal strain
0.3 = lateral strain / 0.0009866
Lateral strain = 0.000296
Lateral strain = Change in diameter / original diameter
0.000296 = Change in diameter / 22
Change in diameter = 0.00651 mm
