A laser beam is to be directed through a small hole in the center of a circle of radius feet. the origin of the beam is feet from the circle. at what angle of elevation should the beam be aimed to ensure that it goes through the hole?
Based on the radius of the circle and the origin of the beam, the angle of elevation to ensure that the beam goes through the hole is 15.95°.
What angle of velocity is needed for beam accuracy?The best operation to use would be the Tangent as the angle we are looking for is adjacent to the circle.
Solving gives:
tan (angle) = Radius of hole / Distance of beam
Angle = tan ⁻¹ (Radius of hole / Distance of beam)
= tan⁻¹ (10 / 35)
= 15.95°

Heterotrophs obtain energy from all of the following except
Assume that louisa carried an average balance of $1,000 from her credit card purchases over the past year. the a.p.r. on her credit card for the past year was 19.99%. approximately how much interest would louisa have paid over the course of the year?
The approximate amount of interest that louisa would have paid over the course of the year is; $200.
How to Calculate Simple Interest?The amount of interest accrued in simple interest is given by the formula:
E = P*i*t
Where;
P is the balance.
i is the interest rate.
t is the time.
We are given;
Balance; P = $1,000, hence
APR of 19.99% and so i = 0.1999
time; t = 1 year.
Thus, the amount she will pay is:
E = 1000 * 0.1999 * 1
E = $199.9
Approximating to a whole number gives;
E = $200

Acids increase the concentration of hydronium ions in solution by donating hydrogen ions to water molecules. true false
The statement about Acids increasing the concentration of hydronium ions in solution is; True
What is the concentration of the solution?In pure water and in neutral solutions, we know that the Hydroxonium ions [H₃O⁺] and Hydroxyl Ions [OH⁻] are equal. Therefore, [H₃O⁺] = [OH⁻] = 1 * 10⁻⁷.
However, that concentration can be altered by the addition of an acid or abase. Thus, If an acid is added to pure water the concentration of hydronium ions in the solution will increase.

What would the population size of sika deer be one year after the carrying capacity increased to 70,000 as a result of deforestation? assume rmax does not change.
The population size of Sika deer one year after the carrying capacity increased to 70000 as a result of deforestation is; 63667 deer
How to Calculate Growth Rate?We are given the following about the Sika deer population;
Initial Population in 2005 = 26000
Stabilized Population between 2012 and 2014 = 58000
r_max for population = 0.57
Now, we want to find the population size of Sika deer one year after the carrying capacity increased to 70000 as a result of deforestation
Thus;
carrying capacity; k = 70000
population size; N = 58000
max growth rate; r_max = 0.57
Formula for the growth is;
dN/dt = (r_max × N)[(K - N)/K]
Plugging in the relevant values gives;
dN/dt = 0.57 × 58000[12000/70000]
dN/dt = 5667
Thus;
Increase in population = 5667 + 58000
⇒ 63667

At what temperature teq do the forward and reverse corrosion reactions occur in equilibrium?
Standard Gibb's free energy at 298K and 5975K is 3.16×10⁶J and -3.83×10⁵J respectively, and temperature at equilibrium state is 5362.3 K.
What is the standard Gibb's free energy?The complete question is in the brainly link at the end. We can say that;
Standard Gibb's free energy of any reaction is gotten from the formula;
∆G° = ∆H° - T∆S°
where;
∆G° is change in free energy
∆H° is change in enthalpy = 3352 kJ = 3352 × 10³J
∆S° is change in entropy = 625.1 J/K
T is absolute temperature = 298 K
Plugging in the relevant values into the gibbs energy equation gives;
∆G° = (3352 × 10³) - (298 × 625.1)
∆G° = 3.16 × 10⁶J
Gibb's free energy at temperature of 5,975 K is;
∆G° = (3,352 × 10³) - (5,975 × 625.1)
∆G° = -3.83 × 10⁵J
At the equilibrium state, the value of Gibb's free energy is zero. Thus we can calculate the temperature as;
0 = (3352 × 10³)J - (T × 625.1 J/K)
Solving for T gives;
T = 5362.3 K

Consider the following reaction: no(g) + so3(g) ⇌ no2(g) + so2(g) a reaction mixture initially contains 2.0 bar no2 and 1.0 bar so2. determine the equilibrium pressure of so2 if kp for the reaction at this temperature is 0.0118.
The equilibrium pressure for the sulfur dioxide in the reaction has been 0.0843 bar.
What is equilibrium?The equilibrium is the condition in which the partial pressure of the product and the reactant molecules is equal.
The ICE table for the partial pressure is attached.
Based on the pressure of equilibrium, the pressure constant is given as:
[tex]k_p=\rm \dfrac{[pNO]\;[pSO_2]}{[pNO][pSO_3]}\\0.0118=\dfrac{a^2}{(0.86-a)^2}\\a=0.0843[/tex]

What is frost?Water that has changed from a liquid or gas to a solid is called frost. Typically, frost forms on exterior objects like cars, windows, and plants when there is moist air present. Areas with a lot of fog frequently have heavy frosts. Frost develops when an outside surface cools below the dew point.
Temperatures higher than 32 °F can cause frost to occur. A1: The ice coating that forms on surfaces at or below 32 degrees Fahrenheit is what is referred to as frost. On occasion, frost can develop over night on your grass even though the temperature has not fallen below freezing.
When water vapour from an environment above freezing comes into touch with a solid surface, a thin film of ice called "frost" is created.

Give (in order) the correct coefficients to balance the following reaction: h2sncl6 + h2s → sns2 + hcl
Let a, b, c, and d be coefficients in the balanced reaction,
a H₂SnCl₆ + b H₂S → c SnS₂ + d HCl
Count the atoms on both sides and set the amounts equal to each other:
• H : 2a + 2b = d
• Sn : a = c
• Cl : 6a = d
• S : b = 2c
Suppose a = 1. Then
6a = d ⇒ d = 6
2a + 2b = d ⇒ b = (d - 2a)/2 = 2
b = 2c ⇒ c = b/2 = 1
So, the balanced reaction is
1 H₂SnCl₆ + 2 H₂S → 1 SnS₂ + 6 HCl
The correct coefficients in order to balance the reaction is 1, 2, 1, 6
How to determine the correct coefficients to balance the equation?To obtain the correct coefficients in order to balance the reaction, we shall obtain the balance equation. This is shown below:
H₂SnCl₆ + H₂S → SnS₂ + HCl
There are 2 atoms of S on the right side and 1 atom on the left side. It can be balanced by writing 2 before H₂S as shown below:
H₂SnCl₆ + 2H₂S → SnS₂ + HCl
There are 6 atoms of Cl on the left side and 1 atom on the right side. It can be balanced by writing 6 before HCl as shown below:
H₂SnCl₆ + 2H₂S → SnS₂ + 6HCl
Now, the equation is balanced. Thus, the correct coefficients needed to balance the reaction is 1, 2, 1, 6
