From this data, how many male, female, adult, and baby mountain goats do you predict are in the park?
Answer:
80
Explanation:
I literally just did this question lol I hope I helped
In an ecosystem having a park, from the given data there are 71 male,93 female, 103 adults and 61 baby goats in the park.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Which of the following correctly describes how particular type of mirror reflects light? Convex mirrors reflect light to a central point (converging). Concave mirrors reflect light to a central point (converging). Concave mirrors reflect light so the light spreads out (diverging).
Answer:
Concave mirrors reflect light to a central point (converging)
Suppose the source is to the left of the mirror in question.
Parallel rays into the mirror are always reflected towards the focal point.
In the case of a concave mirror the real parallel rays pass thru the focal point.
If the mirror is convex the rays will diverge to the left and act as if they were emanating from the focal point to the right of the mirror.

1.1 A book lies on a table. This book is not moving because:
A there are no forces acting on this book.
B the forces acting on the book are in equilibrium.
C the force that the table exerts on the book is greater than the force
that the Earth exerts on the book.
D the force that the book exerts on the Earth has the same magnitude
as the force that the Earth exerts on the book and therefore they
cancel.
Answer:
B The forces acting on the book are in equilibrium
Explanation:
The book that lies on the table and does not move according to Newton's First Law of motion, because there are no net forces acting on it, therefore the net force (the sum of forces acting on the book) is zero
Therefore, the magnitude of the forces acting on the book and the direction in which the forces acts on the balance each other such that the book is in an equilibrium state because the forces acting on the book (which can cause the book to move) are in equilibrium
Therefore, the book is not moving because the forces on the book are in equilibrium.

What is the momentum of an object with a mass of 50 kg travelling at 8 m/s?
Please answer ASAP
We know that,
p = mv
Where p is momentum,m is mass & v is velocity.From ques. we have;
mass = 50 kgVelocity = 8 m/sSo,
p = 50 × 8
p = 400 kg m/s
p = mv
Clearly, now just put the values
p = 50 × 8
p = 400 kg m/s
The diver uses compressed air to breathe under water. 1700 litres of air from the atmosphere is compressed into a 12-litre gas cylinder. The compressed air quickly cools to its original temperature. Calculate the pressure of the air in the cylinder.
Answer:
The answer is below
Explanation:
A diver works in the sea on a day when the atmospheric pressure is 101 kPa. The diver uses compressed air to breathe under water. 1700 litres of air from the atmosphere is compressed into a 12-litre gas cylinder. The compressed air quickly cools to its original temperature. Calculate the pressure of the air in the cylinder.
Solution:
Boyles law states that the volume of a given gas is inversely proportional to the pressure exerted by the gas, provided that the temperature is constant.
That is:
P ∝ 1/V; PV = constant
P₁V₁ = P₂V₂
Given that P₁ = initial pressure = 101 kPa, V₁ = initial volume = 1700 L, P₂ = cylinder pressure, V₂ = cylinder volume = 12 L. Hence:
P₁V₁ = P₂V₂
100 kPa * 1700 L = P₂ * 12 L
P₂ = (100 kPa * 1700 L) / 12 L
P₂ = 14308 kPa

What is the time required for sound to travel 1.75 km if the temp of the air is 20 C°?
Answer:
Explanation:
The 2 equations we need for this are
[tex]v=331.5+.606T[/tex] and
d = rt. First we need to find the velocity using the first equation, then we will plug it into the distance equation as the rate to find the time.
v = 331.5 + .606(20.0) I used 3 sig figs for the temp instead of the 1 found in 20.
v = 331.5 + 12.1 so
v = 343.6 m/s
Now, before we can find the time in seconds, we need to convert the distance to meters.
1.75 km = 1750 m:
1750 = 343.6t so
t = 5.09 seconds

Two sound waves (speed 343 m/s) have different wavelengths. The first has a wavelength of 5.72 m, and the second a wavelength of 11.44 m. What beat frequency do you hear from these two waves?
Answer:
The beat frequency is 30 Hz
Explanation:
Given;
velocity of the two sound waves, v = 343 m/s
wavelength of the first wave, λ₁ = 5.72 m
wavelength of the second wave, λ₂ = 11.44 m
The frequency of the first wave is calculated as follows;
F₁ = v/λ₁
F₁ = 343 / 5.72
F₁ = 59.97 HZ
The frequency of the second wave is calculated as follows;
F₂ = v/λ₂
F₂ = 343 / 11.44
F₂ = 29.98 Hz
The beat frequency is calculated as;
Fb = F₁ - F₂
Fb = 59.97 HZ - 29.98 Hz
Fb = 30 Hz

Una placa de cobre a 20°C tiene unas dimensiones de 65cm x 78 cm. Encuentra el área de la placa a 400°C; Coeficiente de dilatación del cobre es (17x10^-6 )1/°C
Answer:
El área de la placa es aproximadamente 5102.752 centímetros cuadrados.
Explanation:
Asumamos que el cambio dimensional como consecuencia de la temperatura es pequeña, entonces podemos estimar el área de la placa de cobre en función de la temperatura mediante la siguiente aproximación:
[tex]A_{f} = w\cdot l \cdot [1 + 2\cdot \alpha\cdot (T_{f}-T_{o})][/tex] (1)
Donde:
[tex]w[/tex] - Ancho de la placa, en centímetros.
[tex]l[/tex] - Longitud de la placa, en centímetros.
[tex]\alpha[/tex] - Coeficiente de dilatación, en [tex]\frac{1}{^{\circ}C}[/tex].
[tex]T_{o}[/tex] - Temperatura inicial, en grados Celsius.
[tex]T_{f}[/tex] - Temperatura final, en grados Celsius.
Si sabemos que [tex]w = 65\,cm[/tex], [tex]l = 78\,cm[/tex], [tex]\alpha = 17\times 10^{-6}\,\frac{1}{^{\circ}C}[/tex], [tex]T_{o} = 20\,^{\circ}C[/tex] and [tex]T_{f} = 400\,^{\circ}C[/tex], entonces el área de la placa a la temperatura final:
[tex]A_{f} = (65\,cm)\cdot (78\,cm)\cdot \left[1+\left(17\times 10^{-6}\,\frac{1}{^{\circ}C} \right)\cdot (400\,^{\circ}C-20\,^{\circ}C)\right][/tex]
[tex]A_{f} = 5102.752\,cm^{2}[/tex]
El área de la placa es aproximadamente 5102.752 centímetros cuadrados.

Please answer as if you're teaching someone who has no knowledge of the subject, thank you.
Answer:
(C) 700 N
Explanation:
The given parameters are;
The mass of the mountain climber, m = 100 kg
The angle formed by the rope with the horizontal, θ = 45°
The gravitational field strength, g = 10 N/kg
The weight of the man, W = m × g
∴ W = 100 kg × 10 N/kg = 1,000 N
At equilibrium, we have;
The downward force, the weight of the man, W = The upward force, the vertical component of the tension on the two halves of the rope
We have;
W = T × sin(θ) + T × sin(θ)
∴ 1,000 N = 2 × T × sin(45°)
Therefore, we have;
T = 1,000 N/(2 × sin(45°)) = 707.106781 Newtons
Therefore, the tension in the rope is closest to (approximately) 700 N.
weathering can be either chemical or physical process that action of water causes physical weathering rocks which examples
Frost wedging is a type of physical weathering of rock.
Explanation:
Physical or mechanical weathering affects the rock structurally but does not change the chemical composition. Mechanical forces will rub, break or shatter the rock surfaces. Wedging, abrasion, exfoliation are different types of physical weathering.
Water is one of the main sources which alter the structure of the rocks physically.
Frost wedging occurring due to flow of freezing water over the rocks. This frozen water enters the rock through the cracks and crevices on the rock surface, and will expand inside and makes the rocks to crack further and breaks it apart.
