Explanation:
Essential Knowledge
It is essential that the student be able to distinguish between specialized structures that allow protists and fungi to obtain energy and explore their environment.
Protists
Protists are organisms that are classified into the Kingdom Protista. Although there is a lot of variety within the protists, they do share some common characteristics.
● Protists are usually single celled organisms.
● Live in moist environments.
● Vary in the ways they move and obtain energy.
Protists obtain their energy in several ways.
● Animal-like protists ingest or absorb food after capturing or trapping it.
● Plant-like protists produce food through photosynthesis.
● Fungus-like protists obtain their food by external digestion either as decomposers or as parasites.
● Some protists have both autotrophic and heterotrophic characteristi
The one which best compares the structure in protists and fungi that allow these organism to explore their environment is option B. Some protists move using cilia and flagella. Fungi do not move but have fast growing hyphae.
What are moving aids in protists and fungi ?Protists are the eukaryotes that are not considered to be either fungi, animals, or plants. They are mainly tiny and unicellular. Many unicellular protists are motile and can move by employing flagella, cilia, or pseudopods, especially protozoans.
Cells that employ cilia for movement are typically referred to as ciliates, whereas those that use flagella are typically referred to as flagellates.
In marine, brackish, and freshwater reservoirs, hundreds of species of the ciliate genus Paramecium or flagellated Euglena can be found; the green alga Chlamydomonas is found in soil and freshwater all over the world.
Due of their inability to move, fungi produce spores that resemble seeds. These spores spread by the wind, animals, etc., and seek out new environments to flourish.
As the primary means of vegetative growth in the majority of fungi, hyphae are referred to as a mycelium. Therefore, option B is correct.

Explanation:
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

Explanation:
need help due in 30 mins
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 lever of class 1 has a lotal length of 3m and is
able to lift a load of 60N with a force of 30N at a Time Find
the position of the fulcrum.
Answer:
Fin Lin = Fo Lo Work = Work out where in = input and o = output
Fin / Fo = Lo / Lin = 30 / 60 = 1/2 (input force = 1/2 output force)
Lin + Lo = 3
Lo = 3 - Lin
1/2 = (3 - Lin) / Lin from above
1/2 = 3 / Lin - 1
3 / Lin = 1.5 and Lin = 2
So the input length = 2 m and the output length = 1 m

determine the density in kg/m3 of a solid whose mass is 40 and whose dimension in centimetre are 30×4×3
Answer:
Density = 11.11 kg/m³
Explanation:
Given the following data;
Mass = 40 kg
Dimensions = 30×4×3 = 360 cm³ to m³ = 360/100 = 3.6 m³
Thus, volume = 3.6 m³
Now, we can find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Substituting into the equation, we have;
Density = 40/3.6
Density = 11.11 kg/m³

If two alpha particles (each with two protons and two neutrons) are 0.500 m apart, what is the electric potential energy of the system?
Answer:
U = 1.84 10⁻²⁷ J
Explanation:
Electric potential energy is
U = k q₁q₂/ r
in this case the electric charge is
q = 2 p
q = 2 1.6 10⁻¹⁹
q = 3.2 10⁻¹⁹ C
indicate the distance between the charges is 0.500 m
we calculate
U = 9 10⁹ 3.2 10⁻¹⁹ 3.2 10⁻¹⁹ /0.500
U = 1.84 10⁻²⁷ J

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).

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

1. How does a lunar eclipse happen?
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.
