What is the total kinetic energy of a 0. 15 kg hockey puck sliding at 0. 5 m/s and rotating about its center at 8. 4 rad/s? the diameter of the hockey puck is 0. 076 m.
The mass of the puck is
m = 0.15 kg.
The diameter of the puck is 0.076 m, therefore its radius is
r = 0.076/2 = 0.038 m
The sliding speed is
v = 0.5 m/s
The angular velocity is
ω = 8.4 rad/s
The rotational moment of inertia of the puck is
I = (mr²)/2
= 0.5*(0.15 kg)*(0.038 m)²
= 1.083 x 10⁻⁴ kg-m²
The kinetic energy of the puck is the sum of the translational and rotational kinetic energy.
The translational KE is
KE₁ = (1/2)*m*v²
= 0.5*(0.15 kg)*(0.5 m/s)²
= 0.0187 j
The rotational KE is
KE₂ = (1/2)*I*ω²
= 0.5*(1.083 x 10⁻⁴ kg-m²)*(8.4 rad/s)²
= 0.0038 J
The total KE is
KE = 0.0187 + 0.0038 = 0.0226 J
Answer: 0.0226 J
Find the measure of a negative angle coterminal with 95°.
The measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Thus, option (b) is correct.
What is coterminal?Angles in common position (angles with the starting side on the positive x-axis) that have a shared terminal side are referred to as coterminal angles. It's as easy as subtracting or adding 360° or 2 to each inclination, depending on whether it's measured in degrees or trigonometric functions. There are an endless amount of coterminal angles to be discovered.
The measure of a negative angle coterminal with 95°
Ф + 360 n
n is any integer (negative or positive)
Ф = 95°,
- 3n is an integer,
The co-terminal angles of 95° are,
= 95° + 360° (-3n)
= 95° - (1080 n)° ; for any integer n.
As a result, the measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Therefore, option (b) is correct.

Using the equations 2 sr(s) + o₂ (g) → 2 sro (s) ∆h° = -1184 kj/mol co₂ (g) → c (s) + o₂ (g) ∆h° = 394 kj/mol determine the molar enthalpy (in kj/mol) for the reaction c(s) + 2 sro(s) → co₂ (g) + 2 sr(s).
Considering the Hess's Law, the enthalpy change for the reaction is 790 kJ/mol.
Hess's Law indicates that the enthalpy change in a chemical reaction is the sum of the ∆H of each stage of the reaction will give us a value equal to the ∆H of the reaction when it occurs in a single stage.
In this case you want to calculate the enthalpy change of:
C(s) + 2 SrO(s) → CO₂ (g) + 2 Sr(s)
You know the following reactions, with their corresponding enthalpies:
Equation 1: 2 Sr (s) + O₂ (g) → 2 SrO (s) ∆H° = -1184 kJ/mol
Equation 2: CO₂ (g) → C (s) + O₂ (g) ∆H° = 394 kJ/mol
First stepIn this case, first, to obtain the enthalpy of the desired chemical reaction you need 1 mole of C (s) on reactant side and it is present in second equation. But since this equation has 1 mole of C (s) on the product side, it is necessary to locate this on the reactant side (invert the reaction). And when an equation is inverted, the sign of ΔH also changes.
Second stepNow, 2 moles of SrO (s) must be a reactant and is present in the first equation. Since this equation has 2 moles of Sr0 (s) on the product side, it is necessary to locate the O on the reactant side (invert the reaction) and the sign of ΔH changes.
SummaryIn summary, you know that two equations with their corresponding enthalpies are:
Equation 1: 2 SrO (s) → 2 Sr (s) + O₂ (g) ∆H° = 1184 kJ/mol
Equation 2: C (s) + O₂ (g) → CO₂ (g) ∆H° = -394 kJ/mol
Adding or canceling the reactants and products as appropriate, and adding the enthalpies algebraically, you obtain:
C(s) + 2 SrO(s) → CO₂ (g) + 2 Sr(s) ΔH= 790 kJ/mol
Finally, the enthalpy change for the reaction is 790 kJ/mol.

2.Can compare similarities found in reference sequences to determine any potential relations
3.Somatic cell mutations are not passed to the next generation.
4.They are both forms of cell division.
5.They both can pass on genetic variations that can be inherited.
Explanation:
Meiosis is a type of cell division that is specific to germ cells. The correct option is C.
What are germ cells?Germ cells differentiate to create male along with female gametes, sperm, and unfertilized eggs (oocytes or ova), and then meiosis occurs to generate a haploid set of chromosomes.
After that, haploid gametes combine to form a diploid zygote, which develops into a new individual.
The eggs and sperm that reproducing organisms use to pass on their genomes from generation to generation are referred to as germ lines (parents to offspring).
Germ cells are egg and sperm cells, as opposed to somatic cells, which are all other cells in the body.
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half. This process is necessary for the production of egg and sperm cells for reproduction.
Thus, the correct option is C.
