Answer:
I want to say decomposers, because they break down plants that the herbivores eat, and they can also decompose the remains of a scavenger, herbivore, OR carnivore, that was killed and eaten by a carnivore, and maybe even found and eaten by a scavenger. I'm sorry if it's not correct, that's just what my brain has decided right now

Answer:
1. v₂ = 12.43 m/s
2. I₁ = - 80 N.s
3. I₂ = 80 N.s
Explanation:
Consider the following data given in the question:
m₁ = mass of the Cart 1 = 16 kg
m₂ = mass of the Cart 2 = 7 kg
u₁ = velocity of cart 1 before collision = 4 m/s
u₂ = velocity of cart 2 before collision = 1 m/s
v₁ = velocity of cart 1 after collision = - 1 m/s
v₂ = velocity of cart 2 after collision = ?
1.
Applying the law of conservation of momentum:
[tex]m_{1}u_{1} + m_{2}u_{2} = m_{1}v_{1} + m_{2}v_{2}\\(16\ kg)(4\ m/s)+(7\ kg)(1\ m/s)=(16\ kg)(-1\ m/s)+(7\ kg)(v_{2})\\v_{2} = \frac{87\ kg.m/s}{7\ kg}[/tex]
v₂ = 12.43 m/s
2.
Impulse of cart 1 = I₁ = m₁(v₁ - u₁)
I₁ = (16 kg)(- 1 m/s - 4 m/s)
I₁ = - 80 N.s
3.
Impulse of cart 2 = I₂ = m₂(v₂ - u₂)
I₂ = (7 kg)(12.43 m/s - 1 m/s)
I₂ = 80 N.s
A 1500 kg car is being lifted by a hydraulic jack attached to a flat plate. Underneath the plate is a pipe with radius of 24 cm at the top and 2cm at the bottom. To generate an upward acceleration for the car of 1.0 m/s2, how much force must be applied to the small end of the pipe? The answer is NOT 102 N btw
Answer:
The force that must be exerted at the other end is 102.08 N/m₂
Explanation:
Using Pascal's formula; P₁ = P₂
P₁ = F₁/A₁ = m*g/(πr²)
m = 1500 kg; g = 9.8 m/s², r = 24 cm = 0.24 m
P₁ = (1500 * 9.8)/(22/7 * 0.24 * 0.24)
P₁ = 81235 N/m²
P₂ = F₂/A₂
A₂ = πr² where π = 22/7; r = 2.00 cm = 0.02m
A₂ = 22/7 * 0.02 * 0.02 = 0.00126 m²
P₂ = F₂ / 0.00126 m₂
substituting in the formula P₁ = P₂
81235 N/m² = F₂ / 0.00126 m²
F₂ = 81235 N/m² * 0.00126 m²
F₂ = 102.08 N/m₂

There is a bell at the top of a tower that is 45m high. The bell mass is 190. Calculate its potential energy.
Answer:
83790 J.
Explanation:
Potential Energy: This can be defined as the energy possessed by a body, by vitue of it position in the gravitational field. The S.I unit of Potential Energy is Joules (J).
From the question,
P.E = mgh........................................... Equation 1
Where P.E = potential Energy of the bell, m = mass of the bell, h = height of the tower, g = Acceleration due to gravity.
Given: m = 190 kg, h = 45 m.
Constant: g = 9.8 m/s²
Substitute these values into equation 1
P.E = 190×45×9.8
P.E = 83790 J.
Hence the potential energy of the bell is 83790 J.
The burning of wood in a campfire is which type of reaction?
A. Exothermic, because energy is absorbed from the surroundings
B. Endothermic, because energy is released to the surroundings
C. Exothermic, because energy is released to the surroundings
D. Endothermic, because energy is absorbed from the surroundings
If energy is conserved, then:
O A. initial (PE + KE) = final (PE + KE).
O B. the initial KE must be zero.
O C. the momentum does not change.
O D. PE(before) = KE(before).
If energy is conserved, then initial (PE + KE) = final (PE + KE). So, the correct option is A.
What is meant by Law of Conservation of Energy ?The law of conservation of energy states that, energy can neither be created nor be destroyed, but can be transformed from one form to another.
Here,
According to law of conservation of energy,
The total energy of an isolated system remains constant. That means, the total energy of the system in the initial state will be same as that in the final state.
The total mechanical energy is the sum of kinetic energy and potential energy.
TE = KE + PE
Therefore, the energy to be conserved in the system,
Initial TE = Final TE
So, Initial (KE + PE) = Final (KE + PE)
Hence,
If energy is conserved, then initial (PE + KE) = final (PE + KE).

The length of the track itself is 500m. The vehicles (each of mass 15kg) are dragged
along the track back to the top of the ride in stacks of 4. The force required to drag
them at constant speed is 200N
Use an equation from page 2 to calculate the total work done in dragging the stack
back to the start of the ride
Answer:
W = 100000 J = 100 KJ
Explanation:
Here we will use the most basic and general formula of work, which is as follows:
[tex]W = Fd[/tex]
where,
W = Work Done = ?
F = Force Required = 200 N
d = Length of Track = 500 m
Therefore,
[tex]W = (200\ N)(500\ m)\\[/tex]
W = 100000 J = 100 KJ

People living near wind farms sometimes object to them because of visual pollution and what other
form of pollution?
Answer:
Wind turbines are a source of clean renewable energy, but some people who live nearby describe the shadow flicker, the audible sounds and the subaudible sound pressure levels as "annoying." They claim this nuisance negatively impacts their quality of life
Another form of pollution in the farm is called noise pollution
Noise pollution is simply known as disturbing or elevated sound that constitute nuisance and affects the health and well-being of people.Noise pollution from farm includes animals making different sounds, sounds from farm machineries and farm equipment etc.Conclusively, we can say that another form of pollution in the farm is called noise pollution

Wiley coyote pushes a 5kg boulder from an initial height of 10m, the boulder rolls down the hill, across the road, and up the hill on the left. The rock is able to reach a height of 17 m before rolling back down. How fast did Wiley have to push the rock to make this happen?
Answer:
v = 11.7 m / s
Explanation:
For this exercise we can use the conservation of energy
starting point. Where you drop the stone
Em₀ = K + U = ½ m v² + m g h₁
final point. Point where the stone arrives
Em_f = U = mgh₂
We are assuming that there is no friction, so the energy is conserved
Em₀ = Em_f
½ m v² + m g h₁ = m g h₂
v² = 2g (h₂-h₁)
let's calculate
v² = 2 9.8 (17 - 10)
v = √137.2
v = 11.7 m / s

2. How does a solar eclipse happen?
3. Which one occurs more often?
Answer:
1.lunar eclipse- happen when Earths shadow block the sun light
2.solar eclipse-A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight
3. lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Force.
Force = Mass * Acceleration.
here, Mass = 45 kg and Force = 65 N
hence, Acceleration = 65/45
===> Acc. = 1.44 m/s^2
hence the acceleration is 1.44 m/s^2

The compass is a small bar magnet that’s free to spin. Based on what you observed, is the coil of wire with current passing through it a magnet?
Answer:
People have been aware of magnets and magnetism for thousands of years. The earliest records date back to ancient times, particularly in the region of Asia Minor called Magnesia—the name of this region is the source of words like magnet. Magnetic rocks found in Magnesia, which is now part of western Turkey, stimulated interest during ancient times. When humans first discovered magnetic rocks, they likely found that certain parts of these rocks attracted bits of iron or other magnetic rocks more strongly than other parts. These areas are called the poles of a magnet. A magnetic pole is the part of a magnet that exerts the strongest force on other magnets or magnetic material, such as iron. For example, the poles of the bar magnet shown in Figure 20.2 are where the paper clips are concentrated.
A bar magnet with paper clips attached to it.
Figure 20.2 A bar magnet with paper clips attracted to the two poles.
If a bar magnet is suspended so that it rotates freely, one pole of the magnet will always turn toward the north, with the opposite pole facing south. This discovery led to the compass, which is simply a small, elongated magnet mounted so that it can rotate freely. An example of a compass is shown Figure 20.3. The pole of the magnet that orients northward is called the north pole, and the opposite pole of the magnet is called the south pole.
Answer:
Yes, the coil of wire with current passing through it is a magnet.
