Answer:
D: All
Explanation:
In cats, noise pollution causes what is known as acoustic stress in them.
In birds, noise pollution delays their nesting because it makes their songs which they use to probe to be at a low frequency.
Noise pollution affects humans because it can lead to loss of hearing, sleep disturbance, stress, high blood pressure e.t.c
Therefore, it affects Cats, birds and humans.
So option D is correct.
Limestone cave can develop when Limestone rock is weathered. The weathering of the rock leaves an empty space that forms the cave. Which of the following best explains how the Limestone weathered?
Answer:
he shape is like granite, other rocks like this are shaped in the weather.
Explanation:
He shape is like granite, other rocks like this are shaped in the weather.
What is Limestone?The primary source of the substance lime is limestone, a form of carbonate sedimentary rock composed primarily of calcium carbonate (CaCO3).
The minerals calcite and aragonite, which are various crystal forms of CaCO3, make up the majority of its material. As these minerals separate from water that has dissolved calcium, limestone is created.
Both biological and nonbiological activities can contribute to this, while biological processes—like the buildup of corals and shells in the sea—have probably been more significant during the past 540 million years.
Therefore, He shape is like granite, other rocks like this are shaped in the weather.

The less mass an object has, the --- its gravitational f
Answer:
The less mass an object has, the less its gravitational [force.]
Explanation:
Newton's Law of Gravity states that [tex]F_G=\frac{Gm_1m_2}{r^{2}}[/tex]. The two m values are the objects' masses, G is the gravitational constant, and r is the distance between the objects' centers. Notice how the mass values are in the fraction's numerator? That means increasing the mass of one or both objects increases [tex]F_G[/tex]. That also implies the inverse; decreasing the mass of one or both objects decreases [tex]F_G[/tex]!

How can you prove that air contains carbon dioxide?
Answer:
Limewater can be used to detect carbon dioxide. If carbon dioxide is bubbled through limewater then it turns from clear to cloudy/milky in colour. This is why limewater used in a simple respirometer can show that more carbon dioxide is present in exhaled air compared to inhaled air.
Explanation:
Answer:
Explanation:
Carbon dioxide (CO 2) is colorless and odorless, so you can't detect it through direct observation. You'll need to collect an air sample (or a CO 2 sample), then run one of several simple tests to identify the presence of the gas
what does it mean for a disease to be X linked?
Answer:
X-linked is a trait where a gene is located on the X chromosome. Humans and other mammals have two sex chromosomes, the X and the Y. In an X-linked or sex linked disease, it is usually males that are affected because they have a single copy of the X chromosome that carries the mutation.

Look carefully at the diagram below, which shows two cells connected in series. What will the reading on the ammeter be?
Enter your answer as a number
Submit
1.5v
1.5v
Answer:
The reading on the ammeter is 0 ampere
Explanation:
When two or more voltage sources are arranged in series as shown in the diagram, the resultant voltage is given by the sum of the voltages by taking into consideration the direction of the polarities of the voltage sources which can be either series aiding voltage source configuration or series opposing voltage source configuration
In the series aiding voltage source configuration, the positive terminal of one voltage source is connected to the negative terminal of the next voltage source such that the current flows in the same direction in both sources of the voltage in the circuit and the resultant voltage source is given by adding the individual voltage sources together
However, in the series opposing voltage source configuration, the positive terminal of one voltage source is connected to the positive terminal of the next voltage source such that the current flows in opposite direction in both voltage sources and the voltage across the entire voltage sources is given by finding the sum of the differences of the opposing voltage sources
The arrangement of the voltage sources in the question is one of a series opposing voltage configuration and the voltage across both voltage sources is given by subtracting one (usually the smaller voltage source) from the other as follows;
[tex]V_{(series \ opposing)}[/tex] = V₁ - V₂
Where;
V₁ = The voltage of one (usually the larger) of the voltage source = 1.5 V
V₂ = The voltage of the other voltage source = 1.5 V
Therefore;
[tex]V_{(series \ opposing)}[/tex] = 1.5 V - 1.5 V = 0 V
The reading on the ammeter = The current in the circuit, 'I', which is given as follows;
V = I·R
∴ I = V/R = 0/R = 0
I = 0 A (ampere)
The reading on the ammeter = I = 0 A (Current cannot flow without the presence of a voltage).

A 0.42 kg soccer ball is moving down field with a velocity of 12 m/s. A player kicks the ball so that it has a final velocity of 18 m/s down field. What is the change in the balls momentum? and find the constant force exerted by the players foot on the ball if the two are in contact for 0.020 s?
Answer:
the change in momentum is 2.52 N·s
the constant force on the ball while in contact with the players foot is 126 N
Explanation:
p=momentum
m=mass
v=change in velocity
p=(0.42)(6)
p=2.52
The change in the ball's momentum is 2.52 kgms⁻¹
The constant force exerted by the players foot on the ball is 126 N
From the question,
We are to determine the change in momentum of the ball
Change in momentum calculated by using the formula,
[tex]\rho = m(v-u)[/tex]
Where [tex]\rho[/tex] is the change in momentum
[tex]m[/tex] is the mass
[tex]v[/tex] is the final velocity
and [tex]u[/tex] is the initial velocity
From the given information,
[tex]m = 0.42 \ kg[/tex]
[tex]u = 12 \ m/s[/tex]
[tex]v = 18 \ m/s[/tex]
Therefore,
Change in the ball's momentum,
[tex]\rho = 0.42 (18-12)[/tex]
[tex]\rho = 0.42 (6)[/tex]
[tex]\rho = 2.52 \ kgms^{-1}[/tex]
Hence, the change in the ball's momentum is 2.52 kgms⁻¹
For the force exerted by the players foot
Force is given by change in momentum with time
That is,
[tex]F = \frac{\rho}{t}[/tex]
Where
[tex]F[/tex] is the force
[tex]\rho[/tex] is the change in momentum
and [tex]t[/tex] is the time
From the given information
[tex]t = 0.020 \ s[/tex]
Therefore,
[tex]F = \frac{2.52}{0.020}[/tex]
[tex]F = 126 \ N[/tex]
Hence, the constant force exerted by the players foot on the ball is 126 N

According to Einstein, space and time are relative and are parts of a whole universe that has four dimensions. Masses in the universe curved space-time, and the resulting shape of space-time cause gravity.
The above theory is known as the General Relativity or General Theory of Relativity and it was published in 1915 by Albert Einstein.
Basically, it states that universe curved space-time is directly proportional to the energy and momentum of matter and radiation that is present. Thus, gravity is the universe curved space-time caused by massive objects.

Answer: B) Cells come in different shapes and different sizes.
Explanation:
Cell is the basic unit of life. Each cell forms the an integral component of the body of the living organism. The cell structure and function varies from organism to organism. The cells of the plants are comparatively larger than the animal cells. The plant cells are usually rectangular in shape whereas that of animals are usually circular or round in shape. The shape and size of the cells can vary depending upon the function and structure of the organism.

A 15 n net force is used to move a 5kg box. What is the resulting acceleration?
A. 15m/s^2
B. 5m/s^2
C. 20m/s^2
D. 3m/s^2
Answer:3 m/s
Explanation:
The resulting acceleration to move the 5Kg box is equal to 3m/s². Therefore, option (D) s correct.
What is acceleration?Acceleration can be defined as the rate of change in the velocity of an object with respect to time. The acceleration of an object is a vector parameter with both magnitude and direction. Acceleration is also defined as the first derivative of the velocity w.r.t. time and the second derivative of position w.r.t. time and
According to Newton's 2nd law of motion, the force is equal to the product of the mass (m) and acceleration.
F = ma
And, a = F/m
Therefore, the acceleration (a) inversely proportional to the mass (m).
Given, the force used to move the box, F = 15 N
The mass of the given Box, m = 5 Kg
The resulting acceleration, a = 15/5 = 3 m/s²
Therefore, the acceleration of the box is equal to 3 m/s² when it is pushed with a force of 15 N.
