The wavelength of a wave traveling along a string can be calculated using the following formula:
What is wavelength?
Wavelength is the distance between two consecutive points of the same phase on a wave. It is the distance traveled by a wave in one period (the time it takes for the wave to complete one cycle). The wavelength is usually denoted by the Greek letter lambda (λ).
wavelength = speed of wave / frequency
The speed of a wave traveling along a string is equal to the square root of the tension in the string divided by the mass per unit length of the string. If you know the tension in the string and the mass per unit length of the string, you can use the following formula to calculate the speed of the wave:
speed of wave = sqrt(tension / (mass per unit length))
Once you have the speed of the wave, you can use the formula above to calculate the wavelength.
Alternatively, if you know the length of the string and the frequency of the wave, you can use the following formula to calculate the wavelength:
wavelength = length of string / number of waves
In this case, the number of waves is equal to the frequency of the wave multiplied by the time it takes for one wave to pass a fixed point.

Speed is distance over time, so v = λ / T. The frequency, f, is 1/T, so the equation relating wave speed, frequency, and wavelength is v = f λ . where µ = m / L is the string's mass per unit length.

A 100 L ball is blown up inside at 200K. It is then taken outside in the hot sun, and the volume increases to 150 L. What is the new temperature?
Answer:
Temperature, T2 = 300 Kelvin
Explanation:
Given the following data;
Initial volume = 100 Liters
Initial temperature = 200 Kelvin
Final volume = 150 Liters
To find the final temperature T2, we would use Charles' law.
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles is given by;
[tex] \frac {V}{T} = K[/tex]
[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]
Making T2 as the subject formula, we have;
[tex] T_{2}= \frac{V_{2}}{V_{1}} * T_{1}[/tex]
Substituting into the formula, we have;
[tex] T_{2}= \frac{150}{100} * 200[/tex]
[tex] T_{2}= 1.5 * 200 [/tex]
Temperature, T2 = 300 Kelvin

A baseball is thrown with a speed of 36 meters per second (m/s). What is the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate? A-72 B-18 C-41 D-31 Help me out please
Answer:
d = 18 m
Explanation:
Given that,
The speed of a baseball, v = 36 m/s
We need to find the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate.
Let the distance be d. We can find it using the formula,
Speed = distance/time
or
[tex]d=vt\\\\d=36\times 0.5\\\\d=18\ m[/tex]
So, the required distance is equal to 18 m.

The equation below shows a general equation for a reaction, and the amounts of the substance are written underneath.
AB + CD → AC + BD
(15 g) (?) (?) (10 g)
The total mass of the products is 50g. Which best completes the other two amounts?
The amount of CD is 40 g, and the amount of AC is 35 g.
The amount of CD is 35 g, and the amount of AC is 40 g.
The amount of CD and AC would be the same.
The amount of CD and AC is undetermined.
Explanation:
The amount of CD is 35 g, and the amount of AC is 40 g.
Explanation:
AB + CD \rightarrow AC + BDAB+CD→AC+BD
The law of conservation of mass states that in any chemical reaction, the total mass of the reactants must be equal to the total mass of the products.
In this reaction, we know the mass of one reactant (AB, 15 g) and the mass of one product (BD, 10 g). In order to have the same total mass on the left side and on the right side of the equation, the mass of AC must be 5 g more than the mass of CD. We see that the only choice that satisfies this condition is:
The amount of CD is 35 g, and the amount of AC is 40 g.
In fact, if we assume these masses are correct, we have:
- on the reactant side: m(AB)+m(CD)= 15g + 35g = 50g
- on the product side: m(AC)+m(BD)= 40g + 10g = 50g
so, we have the same mass on both sides of the equation, and the law of conservation of mass is satisfied.
Answer:
B is the answer on edge
Explanation:
B: The amount of CD is 35 g, and the amount of AC is 40 g.

Calculate the force of an object shot in the air with a mass of 2 kg and an acceleration of 9.81 m/s2.
Answer:
Force = 19.62 Newton
Explanation:
Given the following data;
Mass = 2kg
Acceleration = 9.81 m/s²
To find the force;
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
Substituting into the formula, we have;
Force = 2 * 9.81
Force = 19.62 Newton
What can we say about the forces? A. They are balanced. B. They are unbalanced. C. They are not in equilibrium.
You can say anything you want to about them without fear of contradiction. There's no information here to prove you wrong.
Your little cousin loves ice cream bars. You buy him one and he starts to lick it. As you sit down on a park bench, he drops
the bar on the seat of the bench. You pick up the bar to throw it away, but he starts to cry, so you shrug and give it back to
him. Will he definitely get sick?
Answer:
nop
Explanation:
It is not certain whether the child will get sick from eating the ice cream bar that was dropped on the bench.
What is contamination?Contamination refers to the presence or introduction of harmful substances or organisms into a material, environment, or food source.
There is a possibility that the ice cream bar could have picked up bacteria or other contaminants from the bench that could make the child sick. However, the risk of illness depends on a number of factors, including the cleanliness of the bench, the length of time the ice cream was in contact with the bench, and the overall health of the child's immune system.
To reduce the risk of illness, it is important to wash hands and surfaces frequently, especially when handling food. If possible, it is best to discard food that has come into contact with potentially contaminated surfaces to prevent the spread of illness. However, if the child has already eaten the ice cream bar and does become sick, it is important to monitor their symptoms and seek medical attention if necessary.
