Answer:
80⁰
Explanation:
triangle AOB = 180
So, a = 50
triangle CAB = a+a+x=180
CAB = 50+50+X=180
CAB = X = 180-100
X=80

Answer:
Explanation:
Since OA = OB (Radius of a circle)
angle OAB = angle OBA = 50
I'm not sure what to do beyond this...

show that for a clósed organ pipe only odd harmonics are present wheras for an open organ pipe all the harmonics are present
Answers
Answer:
For a closed organ pipe, the point at the closed end is always a node, 'N' while the open end is always an antinode, 'A'
Therefore, for a closed organ pipe, we only have;
NA = N↔A = First harmonics = f₁
NANA = NA↔AN↔ NA = Third harmonics, = f₃ = 3·f₁
NANANA = NA↔AN ↔ NA ↔ AN ↔ NA = f₅ = 5·f₁
It can also be shown that for a closed organ pipe, only f₇, f₉, f₁₁, ... are present
Therefore, a closed organ pipe has only odd harmonics present
For an open organ pipe, we have;
ANA = First harmonics = f₁
ANANA = ANA ↔ ANA = Second harmonics = f₂ = 2·f₁
ANANANA = ANA ↔ ANA ↔ ANA = Third harmonics = f₃ = 3·f₁
Similar relationship exist for f₄, f₅, f₆...
Therefore, for an open organ pipe, all harmonics, (multiples of the fundamental, f₁) are present
Explanation:
The graph show a distance travelled by four cars (A, B, C& D) over a period of time . Which car travelled at a greatest speed? *
Answers
Answer:
Car A traveled with the greatest speed.
Explanation:
We know that the steepness of the slope of the line on the distance-time graph represents speed.
Important Tip:
If the slope of the line is more vertical — steep — the speed will be fast.If the slope of the line is more horizontal — flatter — the speed will be slow.For example, at t = 5 seconds, the A car has covered more than 80 meters while all the other cars have covered less than 80 meters during the same period.
IIn fact, during the entire journey, it is clear that from the graph that the slope of the line of A car is more vertical — steep — than the slopes of cars B, C, and D.
Therefore, car A traveled with the greatest speed.
A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m. How much work is done to move the lift this height?
Answers
300N + 950N = 1250N
1250N x 12m = 15000J
Answer = 15000J of work is done.
The total work done to move the lift to this height if, A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m, is 15000 Joules.
What is work done?When an object is moved over a distance by an external force, at least a portion of that force must be applied in the direction of the displacement. This is known as work in physics.
Given:
A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m,
Calculate the total force as shown below,
Total force = Lift weight + man weight
Total force = 300 + 950
Total force = 1250 N
Calculate the work done as shown below,
The work done = Total force × displacement by total force
The work done = 1250 × 12
The work done = 15000 Joules
Thus, the total work done is 15000 joules.

5. A student is investigating the relationship between pressure,
temperature, and entropy. A student manages to obtain a sample of ice,
water, and water vapor that all coexist at the same temperature called
the triple point. Which will have the greatest entropy at the triple point?
Answers
Answer:
The water vapor will have the greatest entropy at the triple point
Explanation:
At the triple point of water, which has the properties of 0.0075°C temperature and 6.11657 mbar pressure, solid ice, liquid water and water vapor exist together in a location
According to Professor Stephen Lower on LibreTexts website entropy is a measure the extent to which thermal energy is shared and spread in a system
The change in entropy, ΔS = ΔH/T
The heat change in [tex]\Delta H_{melting}[/tex] = 6.01 kJ/mol
The heat change in vaporization, [tex]\Delta H_{vaporization}[/tex] = 45.05 kJ/mol
The heat change in sublimation, [tex]\Delta H_{sublimation}[/tex] = 51.06 kJ/mol
Therefore, the entropy of the water vapor [tex]S_{water \ vapor}}[/tex] > The entropy of liquid water, [tex]S_{Liquid \ water}[/tex] > The entropy of the solid ice, [tex]S_{Solid \, ice}[/tex]
The portion with the highest entropy at the triple point is the water vapor
The water vapor will have the greatest entropy at the triple point

A boy moves around a square path of side 15m. He completes 1 round in 40 sec. 1 Calculate the displacement of the boy at the end of 2min 20sec.
Plsss answer fast!
Answers
Answer:
Explanation:
2 min 20 sec = 140 sec .
In 40 sec one round
In 140 sec 140 / 40 round = 3.5 round .
That means the boy will be positioned at the diametrically opposite corner of the square path .
side of square path = 15 m
length of diameter = 15√2
= 21.21 m
Displacement of boy is 21.21 m .
