Answer:
a) The frequency of the third harmonic is 786 Hz
b) The frequency of the first harmonic is 340 Hz
c) The frequency of the fifth harmonic is 1640 Hz
Explanation:
The rule is as follows:
If the first harmonic frequency (also called the fundamental frequency) is F, then:
The frequency of the second harmonic (also called the second overtone) is:
2*F
The frequency of the third harmonic (also called the third overtone) is:
3*F
And so on.
With this information, we can answer the questions:
a) We want to find the frequency of the third harmonic, such that the frequency of the first harmonic is 262 Hz.
Then we have F = 262Hz
And the frequency of the third harmonic will be:
3*F = 3*262Hz = 786 Hz
b) First harmonic for a string whose fifth harmonic frequency is 1700Hz.
Let's define F as the first frequency (the one we want to find)
Then the fifth harmonic frequency can be written as:
5*F = 1700Hz
With this equation we can find the value of F:
F = 1700Hz/5 = 340Hz
c) We want to find the fifth harmonic for a string whose third overtone (this is the same as the third harmonic) frequency is 984 Hz.
Then if the frequency of the first harmonic is F, we know that:
3*F = 984 Hz
With this we can find the value of F:
F = 984 Hz/3 =328 Hz
Now that we know the frequency of the first harmonic, we can find the frequency of the fifth harmonic:
5*F = 5*328 Hz = 1640 Hz

How much power is required to carry a 35 N package a vertical distance of 18 m if the work on the package is accomplished in 30 s?
Answers
Answer:
P = 21 watts
Explanation:
Given that,
Weight of a package, F = 35 N
Distance, d = 18 m
Time, t = 30 s
We need to find the power required to carry the package. Power is equal to the work done divided by time. So,
[tex]P=\dfrac{W}{t}\\\\P=\dfrac{Fd}{t}\\\\P=\dfrac{35\times 18}{30}\\\\P=21\ W[/tex]
So, the required power is 21 watts.

which statement describes a chemical change that occurs when a car's airbag inflates? A. the sodium azide melts into a liquid and increases in volume. B. the sodium azide mixes in the air, forming a solution of gases. C. the sodium azide gets so hot that it changes into a gas. D. the sodium azide breaks down into sodium and nitrogen gas.
Answers
Answer: The correct statement is D (the sodium azide breaks down into sodium and nitrogen gas).
Explanation:
A chemical change is an irreversible chemical reaction in which new substances are usually formed. It is also defined as chemical decomposition of a substance leading formation of two or more other substances. A typical example is in the break down or decomposition of sodium azide into sodium metal and nitrogen gas. This is seen in the chemical balanced equation below:
2 NaN3 --> 2 Na + 3 N2
Sodium azide ( also called Sodium trinitride) is a chemical compound that is in built into automobile air bags which upon collision is being triggered to decompose. This leads to the generation of sodium and nitrogen gas that fills the air bag. This aid ls in reducing the impact of the collision and absorbs the forward-moving energy of the occupant.

A gas cylinder has a volume of 0.4 m? It contains butane at a pressure of 100 kPa and a temperature of
20°C. What pressure is needed to compress the gas to a volume of 0.05 m² at the same temperature?
Answers
The pressure needed : 800 kPa
Further explanationGiven
V₁ = 0.4 m³
P₁ = 100 kPa
T₁ = 20 + 273 = 293 K
V₂ = 0.05 m³
T₂ = T₁ = 293 K
Required
The final pressure(P₂)
Solution
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied
[tex]\tt \rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

7. The sketch shows a painter standing on a
scaffold that is supported by two ropes. The
person weighs 500 N and the force of each
rope is 400 N. Calculate the weight of the
scaffold.
Fr
Answers
Answer:
300NExplanation:
From the question
Weight of painter = 500N
Weight of scaffold = x
Weight of painter + weight of scaffold = 2* 400 (since they are supported by two ropes)
Substitute
500 + x = 2(400)
500+x = 800
x = 800-500
x = 300N
Hence the weight of the scaffold is 300N

What is the height of the counter where a 4 kg fruit basket sits that has 30 J of gravitational potential energy? h= GPE/am
Answers
Answer:
0.765m
Explanation:
gravitational potential energy GPE = mass * acceleration due to gravity * height
Given
GPE = 30Joules
Mass m = 4kg
acceleration = 9.8m/s²
Required
Height h
From the formula
h = GPE/mg
h = 30/4(9.8)
h = 30/39.2
h = 0.765m\
Hence the height of the counter is 0.765m

ON
BSN
10 N
20 N
Answers
Answer:
10 N
Explanation:
Given that,
A man pushes against a tree with a force of 10 newtons.
We need to find the amount of force exerted by the tree on the man.
The force exerted by the tree on the man will be equal to the force that the man exert on the tree as per Newton's third law of motion.
It means the tree exert 10 N force on the man. Hence, the correct option is (c) i.e. 10 N.

A boy on a bicycle drags a wagon full of newspapers at 0.800 m/s for 30.0 min using a
force of 40.0 N. How much work has the boy done?
Answers
Answer:
=57600joules
Explanation:
Given data
Velocity =0.8m/s
Time = 30*60=1800 seconds
Distance =Velocity x time
Distance =0.8*1800
Distance =1440m
Work done = force x distance
Work done =40*1440
Work done =57600joules
Hence the work Done is 57600joules

C.The ocean is denser than the land.
D.The land is denser than the ocean.
Answers
Answer: A.The ocean is colder than the land
Explanation:
Based on the information provided in the question, we are informed that Agustin visits Panama City, Florida, during the month of May and that he feels a shore breeze blowing from the ocean onto the beach.
The reason for the shore breeze is simply due to the fact that the ocean is colder than the land. Since the ocean is colder, anyone who goes to the beach will feel the breeze.
A weight of 4.0 N is used to extend a spring. The extension of the spring is 0.06 m. (i) Calculate the spring constant, k, of the spring.
(ii) State what measurements should be made to determine the extension of the spring produced by the 4.0 N weight.
Answers
Answer:
See explanation
Explanation:
Hookes law states that; the displacement due to a stretching force is directly proportional to the magnitude of the deforming force.
F = ke
F = deforming force
k = force constant
e = extention
k = F/e
k = 4N/0.06 m= 66.67 Nm^-1
To determine the extension of the spring produced by the 4.0 N weight
1) We measure the original length of the spring
2) We measure the length after hanging the 4 N mass
3) Subtract the new length from the original length to determine the extention.
