Answer:
The wavelength can always be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.
Explanation:
Thank me later
Answer:
Explanation:
So what you want to do is measure the wavelength for the wavelength by putting the ruler under or above the distance (show in picture).
amplitude you want to measure it inside of the wave. so when measuring move the ruler sideways.

The2 archer uses a force of 120 N. The force acts on an area of 0.5 cm2 on the archer's fingers. . Calculate the pressure on the archer's fingers.
Answers
Answer:
Pressure = 24000 N/m²
Explanation:
Given the following data;
Force = 120N
Area = 0.5cm² to meters = 0.5/100 = 0.005 m²
To find the pressure;
Pressure= force/area
Pressure= 120/0.005
Pressure = 24000 N/m²
Therefore, the pressure on the archer's fingers is 24000 Newton per meters square.
The pressure on the archer's finger will be [tex]P=240 \ \frac{N}{cm^2}[/tex]
What will be the pressure?Pressure is defined as the normal force applied to the particular area. The formula is given as
[tex]P= \dfrac{F}{A}[/tex]
Here
F= Force applied
A= Area at which the force is applied
Now it is given that
F= 120 N
A= 0.5 [tex]cm^2[/tex]
Now by putting the values in the formula we get
[tex]P=\dfrac{120}{0.5} =240\ \frac{N}{cm^2}[/tex]
Thus the pressure on the archer's finger will be [tex]P=240 \ \frac{N}{cm^2}[/tex]

5. What things would settle in pond water, making it turn to land (terrestrial) succession?
Answers
Answer:
Organic matter
Explanation:
As organic matter continue to build up in a pond, vegetation will begin to appear in the pond. The first set of vegetation to appear are the floating vegetation. Subsequently, submersed plants begin to grow also.
With time, organic sediments continue to fill the pond and its depth is gradually decreased. A swamp or bog is now formed.
This trend of succession continues until the pond eventually turns into land.
Why is average global temperature the most important value when talking about climate change?
Answers
Answer:
The most important number's formal name is "equilibrium climate sensitivity," and it's meant to represent the new equilibrium in surface temperatures after a change in the amount of the Sun's energy trapped here on Earth rather than radiated back to space.
Explanation:
please give me brain list and follow
The average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.
What is temperature?The temperature is the degree of hotness or coldness of the object.
The equilibrium climate sensitivity is the equilibrium in Earth's surface temperature. After the Sun's trapped energy is reduced, the climate changes accordingly.
Thus, the average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.

In order to attain orbit around earth, the ATLAS-V rocket must accelerate up to a
speed of about 7700m/s in about 11 minutes.
a) What average acceleration is required to accomplish this?
b) If the mass of the rocket + fuel is 3.05x105 kg, what is the applied force of the engine?
Answers
= 7700 - 0 / 11
= 700ms^-2
B) force = mass x acceleration
= (3.05 x 105) x 700

A clay ball (mass = 0.25kg) has a rightward momentum of +1.75 kg∙m/s. A second clay ball (mass = 0.25 kg) has a leftward momentum of -1.75 kg∙m/s. The two collide, stick together, and come to a complete stop after the collision.
a) What was the total energy of the system before the collision?
b) What was the total energy of the system after the collision?
Answers
Answer:
the total energy before collision is 12.25J
the total energy after collision is tranfered to sound and heat (by the friction between the two clay balls)
Explanation:
first we should know the velocity of the 2 balls:
momentum=mass ×velocity
we have the momentum and the mass of the 2
so momentum ÷mass=velocity
clay ball 1 velocity=7 m/s & clay ball 2 velocity= -7 m/s
KE=1/2 mv²
1/2 ×0.25×7²=6.125J KE of ball 1
1/2 ×0.25×-7²=6.125J KE of ball 2
add them both we will have 12.25J which is before collision
this energy will then be tranfered to heat and sound as they stop after the collision(velocity =0m/s)

Changing nuclear energy to radiant energy is an example of transforming potential energy into kinetic energy.
What is kinetic energy?Kinetic energy is a type of motion energy (i.e., energy in movement), which is used to perform work.
Conversely, potential energy is a type of energy stored in an object, which can be converted to kinetic energy.Nuclear energy is a type of potential energy because this energy is stored in the atomic nucleus.In conclusion, changing nuclear energy to radiant energy is an example of transforming potential energy into kinetic energy.

How does convection play a role in hurricanes
Answers
Answer:
Convection is what keeps the hurricane going in till the storm hits land.
Explanation:
Convection is the warm, moist current that rises above sea level and as it cools into water vapor it releases energy which a hurricane runs on. Once the hurricane hits land it continues to lose energy to keep it going because there's no convection from the sea currents rising above sea level to release energy.

Decide whether these are true or false. Type out the whole sentence in the space and type a "T" beside the letter. Retype the sentences that are not correct. A. An object has acceleration if its velocity is changing. B. Force is measured in joules. C. Gravity is a force.
Answers
Answer:
1. True.
2. False.
3. True.
Explanation:
A. True: An object has acceleration if its velocity is changing. In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
B. False: Force is measured in joules. Force is a product of the mass of an object and its rate of acceleration. Thus, force is actually measured in Newton.
C. Gravity is a force. Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Two objects have a gravitational force of 800 N. If they are moved twice as far apart and the mass of one object doubles, what is the new gravitational force?
Answers
Answer:
400 N
Explanation:
From the question,
F = kmm'/r²........................ Equation 1
Where F = gravitation force, m and m' = mass 1 and mass 2 respectively, r = distance between the masses.
Given; F = 800 N
Substitute these values into equation 1
800 = kmm'/r².............. Equation 2
If the distance is doubled (2r), and one of the mass is doubled (2m), The new force is
F' = k(2m)(m')/(2r)²
F' = 2kmm'/4r²
F' = kmm'/2r²................. Equation 3
Comparing equation 2 and equation 3
F' = F/2............................ Equation 4
Substitute the value of F into equation 4
F' = 800/2
F' = 400 N

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
