Answer:Given A uniform horizontal beam with a length of 8.00 m and a weight of 200 n is attached to a wall by a pin connection ( allows rotation). Its far end is supported by a cable that makes an angle of 53 degrees with the horizontal. If a 600 n person stands on the beam at 2.00 m from the wall , find the tension in the cable
Now the force acting on the beam are the gravitational force of earth and weight attached to a wall is 200 N which acts at centre. Also force of person standing is 600 N and force exerted is r and tension is T , also torque due to r is zero because it acts at the pivot point. So r = 0
Torque due to tension in the rope is sin 53 x 8.00 x T.
Torque due to force is 2.0 m x 600 N
The weight of beam acts in the centre since the beam is uniform.
So we have
sin 53 x 8.00 x T - 2 m x 600 N - 4 x 200 N = 0
8 .00 x 0.8 x T = 1200 + 800
0.64 T = 2000 N-m
T = 2000 / 0.64
T = 312.5 N
Explanation:
The tension in the cable and the force exerted on the beam by the wall will be 312.5 N and 1200N respectively.
What is force?Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The given data in the problem is;
L is the length 5.00 m long,
[tex]\rm \theta[/tex] is the angle of 53.0°
d is the distance = 1.50 m
T is the tension in the cable
F is the force exerted on the beam by the wall= ?
Torque due to tension in the rope is
[tex]\rm \tau = 8.00 \times sin 53^0 \times T[/tex]
Force due to the torque will be;
F= 2.0 m x 600 N
F= 1200 N
The net tension is found as on applying the static equilibirium equation;
sin 53 x 8.00 x T - 2 m x 600 N - 4 x 200 N = 0
8 .00 x 0.8 x T = 1200 + 800
0.64 T = 2000 N-m
T = 2000 / 0.64
T = 312.5 N
Hence the tension in the cable and the force exerted on the beam by the wall will be 312.5 N and 1200N .

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.

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

Answer:
0.62 m/s
Explanation:
Given that a model train, travelling at speed , approaching a buffer model train buffer spring
The train, of mass 2.5 kg, is stopped by compressing a spring in the buffer.
After the train has stopped, the energy stored in the spring is 0.48 J.
Calculate the initial speed v of the train
Solution
The total energy stored in the spring will be equal to the kinetic energy of the train.
That is,
1/2fe = 1/2mv^2
Substitutes the spring energy, and mass into the formula
0.48 = 1/2 × 2.5 × V^2
2.5V^2 = 0.96
V^2 = 0.96 / 2.5
V^2 = 0.384
V = sqrt ( 0.384 )
V = 0.62 m/s
Therefore, the initial velocity of the train is 0.62 metres per second.

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
One difference between a solar flare and a CME is that a solar flare is composed of ___________, while a CME is composed of __________.

The solar fares consist of 10²² joules, while the plasma is ejected from the solar corona and can be clearly seen from a distance. The Solar flares represent an atmospheric disturbance and plasms are the medium for the growth and development of solar flare and lead to solar activity.What happens to the particles when the temperature decreases?

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.

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.
