Answer:
How does increasing the frequency of a wave affect the wavelength of the wave?
The frequency is defined as the number of full wavelengths that may be completed in a given unit of time (f). The frequency (F) and energy (E) of a wavelength drop as the wavelength's size rises. As a result of these calculations, you may have noticed that the wavelength grows shorter as the frequency rises. The wavelength increases in length in proportion to the reduction in frequency.

Answer:
This isnt exactly an answer, but it should help if you need a general grip on the subject. Its simply an example or model.
Explanation:
It is sort of like being on the road. If you want to get to your destination, you have to follow the correct path or paths, meaning you dont want to steer out of lane because if you do it will be even harder to get where you were going. So as long as you can get a general direction of the frequency you can narrow it down you can find where you are going.

explain how cold water masses form
Question 1
Analyze this: A rightward force of 80 N is applied to a 5.00 kg object to accelerate it to the right. The friction force
between the object and the surface is 30 N. Complete the diagram
The only part of the diagram that remains is the force that moves the object forward which is 50 N.
We know that the net force is obtained using the relation;
Net force = -Frictional force + Rightward force
The frictional force is negative because its direction is opposite to that of the forward force.
We have the following information from the question;
Frictional force = 30 N
Rightward force = 80 N
Mass = 5.00 kg
Net force is obtained from;
5a = 80 - 30
5a = 50
a = 10 m/s^2
Net force = 50 N, This the force that moves the object forward.

The method of measuring distance in space using parallax is equivalent to surveyors on Earth doing _______________. The smaller the parallax of an object, the greater its __________. When we measure parallax, the distance between the two observers (or two vantage points) is called the ___________. The first parallax to a star was not measured until 1838 because the stars are so _______________. The distance at which a star has a parallax of one second of arc is called a __________. In 1989, astronomers launched a satellite called __________ to measure parallax even better from outer space.
Answer:
Triangulation
Distance
Baseline
Far away
Parsec
Hipparcos
Astronomers are known to estimate the distance of nearby objects in space through the use of stellar parallax, or trigonometric parallax.
They often measure a star's movement using the background of more distant stars as Earth revolves around the sun.
With the use of Parallax, one can get the best way to have the distance in astronomy,
Triangulation is often used instead of parallax to know the terrestrial distances by forming triangles with a predefined base and measuring the angles formed with the other two sides.

block a of mass 4m is attached by a light string to block b of mass 2m. the string passes over a pulley with negligible friction and of negligible mass. block a is held a distance h above the ground, as shown. the blocks are released from rest, and block a reaches the ground two seconds later. the value of h is most nearly
The kinematics and Newton's second law allow us to find the height from which the block system descends is:
y = 6.54 m
Given parameters
Body mass m1 = 4 kg The mass of the body on the ground m² = 2 kg The descent time t = 2sTo find
Body height
Newton's second law gives a relationship between the net force, the mass, and the acceleration of the body.
∑ F = m a
Where the bold letters indicate vectors, F is the force, m the mass and the acceleration of the body.
Kinematics studies the movement of bodies, looking for relationships between position, velocity and acceleration
y = v₀ t + ½ a t²
In the attached we have a free body diagram of the system, let's write Newton's second law.
T - W₁ = m₁ a
-T + W₂ = m₂ a
Let's solve the system of equations.
W₂ - W₁ = (m₁ + m₂) a
a = [tex]\frac{m_2-m_1}{m_2+m_1} \ g[/tex]
Let's calculate
a = [tex]\frac{2 -4}{ 2 +4} \ 9.8[/tex]
a = -3.27 m / s²
The negative sign indicates that the heaviest body is descending.
Now we can use kinematics to find the height, as the system comes out of rest the initial velocity is zero, when he reaches the ground his height is zero.
y = y₀ + v₀ t + ½ a t²
0= y₀ + 0 +½ a t²
Let's calculate
y₀ = ½ 3.27 2²
y = 6.54 m
In conclusion, using kinematics and Newton's second law we can find the height from which the block system descends is:
y = 6.54 m

Tonya has been working a lot and has not been able to maintain healthy habits, like diet and exercise, as well as she normally does. This has meant a lot of late nights and eating take-out instead of preparing meals herself. What is the likely result of this change in behavior?
A.
She is at high risk for obesity.
B.
She will probably gain a little weight.
C.
If she is young, there will be no impact.
D.
If she is exercising at all, the effects will be minimal.
PLEASE NO LINKS
Tonya has been working a lot and if she is not able to maintain her healthy then she will probably gain a little weight. Hence, option B is correct.
What is Diet?Diet, in the context of nutrition, refers to the items that a person frequently eats and drinks (or a group). A regulated diet, or one that satisfies a person's physical needs, may be used during a specific illness therapy or health condition management.
For instance, a diabetic's diet may be limited to a variety of foods and beverages that help control blood sugar levels. Numerous fiber, non-starchy fruits, and vegetables are included in the diet suggested for diabetic patients. Because starchy foods are high in carbohydrates, eating a lot of them could raise your blood sugar levels.
If Tonya has been working a lot and is not able to maintain healthy habits as she normally does then she will gain some weight. But she must make sure to start a healthy lifestyle as soon as possible because in a long run this habit can affect her health very badly.

8 kg cat is running with a velocity of 4 m/s. What is the cat's momentum?
Answer:
Kinetic energy = (1/2) (mass) (speed)²
Kinetic energy = (1/2) (8 kg) (4 m/s)² =
(4 kg) (16 m²/s²) =
64 (kg-m/s²) (m) = 64 newton-m = 64 joules
A cat of mass 8 kg moving with a velocity of 4 m/s, then the momentum of the cat's movement will be equal to 32 kg m/s.
What is momentum?The momentum is the result of a particle's velocity and its mass. Force and motion, meaning it has both magnitude and the direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of increase of momentum.
The impulse, which is the product of the force and the intervals (the impulse), is equal to the difference in momentum, according to Newton's 2nd law, if a steady force operates on a particle for a specific amount of time. On the other hand, a particle's momentum is the amount of time needed for a consistent action to fight it to rest.
As per the data provided in the question,
Mass of the cat, m = 8 kg
Velocity of the cat, v = 4 m/s.
[tex]Momentum(p) = Mass(m)*velocity(v)[/tex]
p = (8 kg) × (4 m/s)
p = 32 kg m/s.
Therefore, the momentum of the cat is 32 kg m/s.

Kinetic energy is energy that possesses due to its motion. Basically, a moving object has kinetic energy.
Potential energy is the energy held by an object due to its position relative to other object. Which means it has the possibility (potential) to become kinetic energy, but at that moment where it’s not moving, it’s potential energy.
