How might a suit of armor be a good analogy for a function of the skeletal system?
It's a frame for your body and protects organs and armor protects your body from injury
D. between radio waves and microwaves
<span>The normal force acting on the bag by the floor is calculated using th data on the force used to push the bag and the coefficient of friction between the bag and the floor. The normal force is determined through the formula Force / kin.coeff. Substituting, 27 N / 0.23 is equal to 117. 39 N. The answer is D.</span>
Answer:
a) C. 7.5 V
b) A. 2.5 V
Explanation:
First, we find the total resistance of the circuit. A voltage divider circuit is a series circuit. Therefore, its total resistance will be the sum of individual resistances:
a)
Now, we will apply the voltage divider rule on this circuit to find the voltage across the 300 Ω Resistor (R₂):
V₂ = 7.5 V
Therefore, the correct option is:
<u>C. 7.5 V</u>
<u></u>
b)
Now, the voltage across the 100 Ω Resistor (R₁) will be:
Therefore,the correct option is:
<u>A. 2.5 V</u>
Answer:
1.18266×10⁻²⁰ J
Explanation:
Applying,
E = (3/2)kT.................... Equation 1
Where E = kinetic energy of the gas molecule, k = Boltzmann's constant, T = Temperature
But,
PV = nRT.............. Equation 2
Where P = pressure, V = Volume, n = number of moles, R = Universal gas constant.
make T the subject of the equation
T = PV/nR............. Equation 3
Substitute equation 3 into equation 1
E = (3/2)k(PV/nR)
E = 3kPV/2nR............... Equation 4
Given: k = 1.38066×10⁻²³ J/K, V = 6.6 L = 0.0066 m³, P = 7.1 atm = (101325×7.1) N/m² = 719407.5 N/m², n = 2.9 mol, R = 8.31451 J/K.mol
Substitute into equation 4
E = (3×1.38066×10⁻²³×0.0066×719407.5)/(2×8.31451)
E = 1182.66×10⁻²³ J
E = 1.18266×10⁻²⁰ J
