Which of the following is a result of a limiting factor in an ecosystem?
a. A pond has only produced a small amount of algae, so the fish population is also small.
b. The weather was extra humid last summer and there were more mosquitos than ever before.
c. A farmer planted new grass and months later his animals looked healthier than they’ve looked in years.
d. This year, ticks are supposed to be worse than in previous years, with a huge number of them carrying Lyme Disease.
Answer:A - a pond has only produced a small amount of algae, so the fish population is also small. i’m pretty sure that’s correct.
Explanation: The amount of alage determines the size,or carrying capasity of the fish population,so it is a limiting factor.

A fall thrown vertically upwards with a speed
of 20 ms-¹ from the top of a tower reaches
the earth in 8seconds. find the height of the
tower.
take g= 10ms-²
Answer:
Height of tower = 480 meter
Explanation:
Given:
Initial velocity = 20 m/s
Time taken to reach ground = 8 second
So,
Final velocity = 0 m/s
Acceleration due to gravity = 10 m/s²
Find:
Height of tower
Computation:
s = ut + (1/2)(g)(t)²
s = (20)(8) + (1/2)(10)(8)²
s = 160 + (1/2)(10)(64)
s = 160 + (10)(32)
s = 160 + 320
s = 480 meter
Height of tower = 480 meter
a uniform metre scale rests horizontally on a knife edge at the 60cm mark when a mass of 10 gram is suspended from one end . at which end this mass be suspended . what is the mass of meter scale?
Answer:
40 gram or 0.04 kilogram
Explanation:
From the diagram attached,
The mass must be suspended at end B.
Applying the principle of moment,
Sum of clockwise moment = sum of anti-clockwise moment.
From the diagram,
Taking the moment about the pivot,
X(60-50) = 0.1(100-60)
Where X = weigth of the meter rule
10X = 4
X = 4/10
X = 0.4 N
X = 0.4/10
X = 0.04 kg
X = 40 g
Hence the mass of the meter rule = 0.04 kg or 40 gram

Explanation:

please help me with this
Answer:
Explanation:
Use the one-dimensional equation for displacement:
Δx = v₀t + [tex]\frac{1}{2}at^2[/tex] where Δx is the displacement, v₀ is the initial velocity (which is 0 since someone had to be holding the penny still before it was dropped), t is the time it takes to travel a certain distance (which is given as 4 seconds), and a is the acceleration due to gravity which is -9.8 m/s/s. Filling in:
Δx = [tex](0\frac{m}{s})(4s)+\frac{1}{2}(-9.8\frac{m}{s^2})(4s)^2[/tex] I'm going to expand this first so you can see how the units work out. First of all, anything times 0 is 0, so what is right in front of the plus sign goes to 0 and I'm going to leave it out. How this looks expanded without doing any of the actual math yet is:
Δx = [tex]\frac{1}{2}(-9.8\frac{m}{s^2})(4^2s^2)[/tex] which makes it apparent that the seconds-squared cancel each other out, leaving us with the meters only. NOW doing the math and rounding to 2 sigfig's even though there's only 1 in the number 4:
Δx = 78 m(the negative would only be used if the question we were answering was how far the penny had to fall, which would then use the negative sign to indicate that the penny is falling to a point that is below th point from which it was released. Since height is a distance measurement, it will never be negative. Keep in mind, asking how far the penny fell is not the same thing in physics as asking how tall the building was that the penny fell from.)

What is Law of energy conservation ?
Law of energy conservation states that energy can neither be created nor be destroyed and can only transform from one form to other form.
From Law of energy conservation we can say that Digestion starts from that very point when we put food in our mouth so the moment you eat the sandwich, it starts getting digested and when it reaches the stomach ,your body converts its chemical energy into the movement of your muscles.
hence , correct option is :
D. Chemical energy stored in the bonds of the molecules of the sandwich is transformed into kinetic energy.

The illustration in figure below shows a uniform metre rule weighing 30 N pivoted on a wedge placed under the 40 cm mark and carrying a weight of 70 N hanging 2 from the 10 cm mark. The ruler is balanced horizontally by a weight W hanging from the 100 cm mark. Calculate the value of the weight W.
Answer:
W = 30 N
Explanation:
Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.
[tex](70\ N)(40\ cm - 10\ cm)-(30\ N)(50\ cm-40\ cm)-(W)(100\ cm - 40\ cm) = 0\\W(60\ cm) = (70\ N)(30\ cm)-(30\ N)(10\ cm)\\\\W = \frac{1800\ N.cm}{60\ cm}[/tex]
W = 30 N
3. What does an object at rest and an object moving at constant velocity have in common?
Differentiate between:
a. Compression and Rarefaction
Answer:
Explanation:
Compression
The region in a medium where the distance between the vibrating molecules is minimum is compression.
This is the region with higher air pressure than the surrounding .
Rarefaction
The region in a medium where the distance between the vibrating molecules is maximum is rarefaction.
This is the region with relatively low air pressure.

A go-cart and rider have a mass of 100 kg. If the cart accelerates at 5 m/s2 during a 25 m sprint, how much work did the cart do
Answer:20watts
Explanation:
Answer:
The solution is given below
Explanation:
The computation is shown below;
We know that
Work done = Fs cosθ
But before that we need to determine the force i.e.
We know that
Force (F) = mass (m) × Acceleration (a)
= 100 × 5
= 500 N
Now, work done by the go-cart is
Work done (W) = Fs cosθ
= 500 × 25 × cos(0°)
= 500 × 25 × 1
= 12,500 J
A rigid body of moment of inertia 0.5 kg.M^2 rotates with 2 RPM. How much torque is needed to increase the rotation to 10 RPM in 5 seconds.
Answer:
T = 0.084 Nm
Explanation:
First, we will calculate the angular acceleration:
[tex]\alpha = \frac{\omega_f - \omega_i}{t}[/tex]
where,
α = angular acceleration = ?
ωf = final angular speed = (10 RPM)(2π rad/1 rev)(1 min/60 s) = 1.05 rad/s
ωi = initial angular speed = (2 RPM)(2π rad/1 rev)(1 min/60 s) = 0.21 rad/s
t = time = 5 s
Therefore,
[tex]\alpha = \frac{1.05\rad/s - 0.21\ rad/s}{5\ s}\\\\\alpha = 0.168\ rad/s^2[/tex]
Now, for the torque:
[tex]T = I\alpha[/tex]
where,
T = torque = ?
I = moment of inertia = 0.5 kg.m²
Therefore,
[tex]T = (0.5\ kg.m^2)(0.168\ rad/s^2)\\[/tex]
T = 0.084 Nm
skater spins over a point at a speed of 3.0 rotations per second then the momentum of inertia is 0.60 kg.M2, what is its angular momentum?
Answer:
[tex]L=11.3\ kg-m^2/s[/tex]
Explanation:
Given that,
Angular speed of a skater, [tex]\omega=3\ rot/s=18.84\ rad/s[/tex]
The moment of inertia of the skater, I = 0.6 kg-m²
We need to find the angular momentum of the skater. The formula for the angular momentum of the skater is given by :
[tex]L=I\omega[/tex]
Substitute all the values,
[tex]L=0.6\times 18.84\\\\L=11.3\ kg-m^2/s[/tex]
So, its angular momentum is equal to [tex]11.3\ kg-m^2/s[/tex].
Do planets revolve slower or faster the closer they are from the sun?
Answer:
The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.
Is this statement correct that all charged particles experience same force in uniform electric field
Answer:
No the statement is incorrect.
Explanation:
Mathematically, force F experience of a charge particle of magnitude q in an uniform electric field E is given as
F = E/q
In uniform electric field is where the intensity of electric field remains same throughout. However, from the above equation it is clear that force experience by the charge particle also depends upon the magnitude of charge particle as well. So, with change in charge particles the force experienced by it also changes.

The distance between 4 nodes (3 sections, 2 sections= wavelength) is 15.0cm. The frequency of the source is 10Hz. What's the speed of the waves in cm/s?
Answer:
the speed of the waves is 150 cm/s
Explanation:
Given;
frequency of the wave, f = 10 Hz = 10
distance between 4 nodes, L = 15.0 cm
The wavelength (λ) of the wave is calculated as follows;
Node to Node = λ/2
L = 2(Node to Node) = (4 Nodes) = 2 (λ/2) = λ
Thus, λ = L = 15.0 cm
The speed (v) of the wave is calculated as follows;
v = fλ
v = 10 Hz x 15.0 cm
v = 150 cm/s
Therefore, the speed of the waves is 150 cm/s
