Answer:
D. 43° 52`
Explanation:
A bearing is an angle, measured clockwise from the north direction. When solving a bearing problem, it is good to represent the bearings in the given question with diagram.
The diagrammatically representation of the bearing of lines A and B, 16° 10` and 332° 18` respectively given in the question is shown in the figure attached.
At Point A, we will calculate angle ∠BAO.
Calculating the angle ∠BAO
∠BAO = 90° - 16° 10`
= 73° 50`
At Point B, we will calculate angle ∠ABO.
Calculating the angle ∠ABO
∠ABO = 332° 18` - 270° 0`
= 62° 18`
At Point O, we will calculate the include angle ∠BOA.
Calculating the angle ∠BOA
∠BAO + ∠ABO + ∠BOA = 180° (sum of angles in a triangle)
73° 50` + 62° 18` + ∠BOA = 180°
136° 8` + ∠BOA = 180°
∠BOA = 180° - 136° 8`
∠BOA = 43° 52`
The value of the included angle BOA is 43° 52
Answer:
Thermal Pollution
Explanation:
Thermal pollution is a <em>term</em> use to describe the <u>final result caused from the water used as a coolant by power plants and/or industrial companies</u>.<em> It changes the water temperature and its quality. It is usually caused from humans or companies especially manufacturing companies - They use it for their personal needs. The end product of the water after being discarded is Thermal Pollution</em>
Answer:
300 meters per second. That's equal to about 670 miles per hour.
Explanation:
Not only are air particles incredibly small, they are always moving. And they move fast. At room temperature, they are going about 300 meters per second. That's equal to about 670 miles per hour.
Answer:
In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.
What is the concentration of H+ ions at a pH = 2?
0.01 mol/L
What is the concentration of OH– ions at a pH = 2?
0.000000000001 mol/L
What is the ratio of H+ ions to OH– ions at a pH = 2?
10,000,000,000 : 1
