Answer:
the carrying capacity will decrease density dependent
Explanation:
The limiting factor of the disease is density dependent and will decrease the carrying capacity of the population because the disease that affect the population operate when the number of organisms in per unit area get to a specific level , it's affected the population when the population per unit are reached a certain level and the disease decrease the carrying capacity of the population. Carrying capacity is the average population size of organisms in an habitat. As the lobsters population is affected by disease, the population sizes reduced because many of the lobsters would of died and inactive, thereby causing a reduction in the size and capacity.
can you tell Which body part does not help in the perception and production of sound in humans?
ears, lungs, mouth or vocal cords
which is not?
Lungs do not help in the perception and production of sound in humans.
What are lungs?Gaseous exchange occurs during inhalation and exhale during breathing. Main components of the human respiratory system include the nose, mouth, throat, larynx, trachea, bronchi, and lungs.
In humans and other vertebrates, the primary organs for respiration are the lungs. They are situated in the thoracic cavity of the chest, on either side of the heart. The lungs are spongy, anatomically speaking, with a total surface area that ranges from 50 to 75 square meters.
The lungs' main job is to make it easier for gases to move from the blood into the air. It's interesting to note that the right lung is significantly larger and heavier than the left.
Hence, lungs do not help in the perception and production of sound in humans.

A cyclist is traveling 10 m/s with an acceleration of 6 m/s2. How fast is the cyclist traveling at the end of 20 seconds
Answer:
The cyclist is traveling at 130 m/s
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
[tex]v_f=v_o+at[/tex]
The cyclist initially travels at 10 /s and it's accelerating at a=6m/s^2. We need to know the new speed when t= 20 seconds have passed.
Apply the above equation:
[tex]v_f=10+6\cdot 20[/tex]
[tex]v_f=10+120[/tex]
[tex]v_f=130\ m/s[/tex]
The cyclist is traveling at 130 m/s

Which of the statements about the nitrogen cycle is not true? Animals get nitrogen by eating plants or other animals Animals get nitrogen by eating plants or other animals Decomposers break down waste to yield ammonium Decomposers break down waste to yield ammonium Nitrogen moves back and forth between the atmosphere and living things Nitrogen moves back and forth between the atmosphere and living things All plants generate nitrogen in their roots
Answer:
decomposers break down waste to yield ammonia.
Explanation:
The nitrogen cycle is the process by which nitrogen circulates among the atmosphere, terrestrial, and marine ecosystems and is converted into multiple chemical forms through both biological and physical processes.
In the nitrogen cycle, decomposers do not break down waste to yield ammonia.
So, the option ''decomposers break down waste to yield ammonia'' is correct.

A car moves at the constant speed of 20 m/s along a straight track for 12 seconds. Calculate how far it travels in meters in this time.
The distance traveled by car with a constant speed of 20m/s is equal to 240m.
What is speed?The speed of an object can be defined as the distance traveled by the object in a definite time interval. The speed is a scalar quantity as it carries only the magnitude and does not have any direction.
The speed can be calculated from the ratio of the distance traveled by the object to the time taken to cover that distance.
The speed equation for an object can be written as follows:
Speed = distance /time taken
Distance = Speed × time
Given, the speed of the car = 20 m/s
The total time taken by car to travel the distance = 12 sec
The distance traveled by car = 20 × 12 = 240 m.
Therefore, the car will travel a distance of 240 meters in a given time.

In a 350-m race, runner A starts from rest and accelerates at 1.6 m/s^2 for the first 30 m and then runs at constant speed. Runner B starts from rest and accelerates at 2.0 m/s^2 for the first 30 m and then runs at constant speed. Runner A befins running as soon as the race begins but B first takes a nap to rest up. What is the longest nap that B can take and still not lose the race?
Answer:
B can take 0.64 sec for the longest nap .
Explanation:
Given that,
Total distance = 350 m
Acceleration of A = 1.6 m/s²
Distance = 30 m
Acceleration of B = 2.0 m/s²
We need to calculate the time for A
Using equation of motion
[tex]s=ut+\dfrac{1}{2}at_{A}^2[/tex]
Put the value in the equation
[tex]30=0+\dfrac{1}{2}\times1.6\times t_{A}^2[/tex]
[tex]t_{A}=\sqrt{\dfrac{30\times2}{1.6}}[/tex]
[tex]t_{A}=6.12\ sec[/tex]
We need to calculate the time for B
Using equation of motion
[tex]s=ut+\dfrac{1}{2}at_{B}^2[/tex]
Put the value in the equation
[tex]30=0+\dfrac{1}{2}\times2.0\times t_{B}^2[/tex]
[tex]t_{B}=\sqrt{\dfrac{30\times2}{2.0}}[/tex]
[tex]t_{B}=5.48\ sec[/tex]
We need to calculate the time for longest nap
Using formula for difference of time
[tex]t'=t_{A}-t_{B}[/tex]
[tex]t'=6.12-5.48[/tex]
[tex]t'=0.64\ s[/tex]
Hence, B can take 0.64 sec for the longest nap .

how can we calculate the e.m.f of the battery?.
Explanation:
The emf is equal to the work done on the charge per unit charge (ϵ=dWdq) when there is no current flowing. Since the unit for work is the joule and the unit for charge is the coulomb, the unit for emf is the volt (1V=1J/C).
Answer:
The EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it. The magnitude of emf is equal to V (potential difference) across the cell terminals when there is no current flowing through the circuit. (byjus)

Melissa is riding on a carousel at a distance of 8.0 m from the center of the ride. She travels at a speed of 1.3 m/s. Melissa has a mass of 45 kg.
A) What is Melissa’s acceleration?
B) What is the net force on Melissa?
Answer:
(A) The acceleration of Melissa is 0.211 m/s²
(B) The net force on Melissa is 9.5 N
Explanation:
Given;
radius of the carousel, r = 8.0 m
speed of Melissa, v = 1.3 m/s
mass of Melissa, m = 45 kg
(A) The acceleration of Melissa is given by centripetal acceleration;
[tex]a_c = \frac{v^2}{r} \\\\a_c = \frac{1.3^2}{8}\\\\a_c = 0.211 \ m/s^2[/tex]
(B) The net Force on Melissa is given by centripetal force;
[tex]F_c = ma_c\\\\F_c = 45 *0.211\\\\F_c = 9.5 \ N[/tex]
c. What did you notice with the acceleration values obtained by the different items? What do you think caused the variations in these values?
Explanation:
The given table gives the acceleration of an object for the different items at 50 N force.
Force acting on an object is given by :
[tex]F=ma[/tex]
As, [tex]a=\dfrac{v-u}{t}[/tex]
where u and v are initial and final velocities
It can be noticed that, as the mass of the object increases and final velocity decreases, the value of acceleration also decreases. It is maximum when the mass is least and the final velocity is most. As mass and velocity is changing, it will cause the change in variations of the value of a.
Variation in the values of acceleration occurs due to the different in the final velocity of different items.
The acceleration values obtained by the different items varies from one another because of different mass as well as final velocity. Acceleration depends on both mass of an object as well as velocity. We know that acceleration is the time rate of change of velocity.
So if the change occur in velocity we also experience change in the acceleration of that object so we can conclude that variation in the values of acceleration occurs due to the different in the final velocity of different items.
