1. How do energy and matter recycle in a closed-loop system?
Answer:
In a closed-loop system, matter is used to generate energy, and the energy generated is used to produce matter, and the cycle goes on without end.
Explanation:
A closed-loop system is one in which materials or energy is recycled without end through a production cycle. This means that a raw material is used to produce a finished product, and the finished product at the end of its use cycle is converted back and used as a raw material to produce more of it again. Energy and matter can also be cycled in the same way in an energy and matter closed-loop system, converting matter to energy, and the energy is put back into the production of more of the matter.
In a closed system loop, the matter has been recycled to provide raw material and form new products. The energy formed by the product has been recycled by being used by the raw materials for the formation of new products.
The closed system loop can be defined as the system in which the products and energy has been recycled continuously to form more products. The energy has been formed in the closed system loop, that can be utilized by the raw materials for the production of energy.
The products formed after reaching the equilibrium of the formation, and dissociation reaches the point, and starts to dissociate to provide the raw material to the system.
Thus, in a closed system loop, the matter has been recycled to provide raw material and form new products. The energy formed by the product has been recycled by being used by the raw materials for the formation of new products.

A ball is dropped from the roof of the A200 building. How fast is a traveling 0.5 seconds later?
ANYTHING that's dropped near the Earth's surface and isn't affected by air resistance falls 9.8 m/s faster at any time than it did 1 second earlier.
0.5 second after it was dropped with zero speed, it's falling at
(0.5) x (9.8 m/s) = 4.9 m/s .
It makes no difference which building it was dropped from.

Answer:
350 miles
Explanation:
because multiply 70 times 5 and you will get 350
A person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.A) What is her average speed over the entire trip?
B) What is her average velocity over the entire trip?
Answer:
A.) 3.975 m/s
B.) 0.925 m/s
Explanation:
Given that a person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.
A) What is her average speed over the entire trip?
The average speed = (4.90 + 3.05)/2
Average speed = 7.95/2
Average speed = 3.975 m/s
B) What is her average velocity over the entire trip?
Since velocity is a vector quantity, that is, we consider both the magnitude and direction
Average velocity = ( 4.90 - 3.05)/2
Average velocity = 1.85/2
Average velocity = 0.925 m/s

Please help me with thus question (picture) D:
well thanks for the Information
Explanation:
Torque = Force * Perpendicular distance of the force = 10N * 0.8m = 8Nm.
In diagram A, both torques are acting in a clockwise direction. Hence the net torque is 2N * 1m + 4N * 1m = 6Nm, clockwise.
In diagram B, the torques are acting in opposite directions. For the clockwise one, its torque is 5N * 4m = 20Nm. For the anticlockwise one, its torque is 2N * 10m = 20Nm. Since they are in opposite directions and are equal, they cancel out each other.
Hence net force = 0N and net torque = 0Nm.

A ball is dropped from a height = HThe total distance covered in last second of its motion is equal to the distance covered in first 3 second .[tex]\rm{\gray{\underline{\underline{\blue{TO\:FIND:-}}}}}[/tex]
The height of the journey .[tex]\rm{\gray{\underline{\underline{\blue{SOLUTION:-}}}}}[/tex]
We have know that,
[tex]\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S\:=\:ut\:+\:\dfrac{1}{2}\:at^2\:}}}}}[/tex]
Where,
S = Distance .u = initial velocity = 0m/st = time = 3sa = acceleration[Note :- Here, acceleration is ‛acceleration due to gravity’ .]
a = 10m/s^2=> S = 1/2 × 10 × (3)^2
=> S = 5 × 9
=> S = 45m -----(1)
✒ If the ball takes ‛n’ second to fall the ground, then distance covered in nth second is,
[tex]\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S_n\:=\:u\:+\:\dfrac{g}{2}\:(2n\:-\:1)\:}}}}}[/tex]
=> Sn = 0 + 10/2 (2 × n - 1)
=> Sn = 5 (2n - 1)
=> Sn = 10n - 5 -----(2)
Therefore,
10n - 5 = 45=> 10n = 45 + 5
=> n = 50/10
=> n = 5
Now put the value of ‛n = 5’ in equation(2), we get
=> Sn = 10 × 5 - 5
=> Sn = 50 - 5
=> Sn = 45m
[tex]\rm{\pink{\therefore}}[/tex] The height of the journey is “ 45m ” .

a man pulls a box with a force of 90.0 N directed along the handle which makes angle of 45 degrees with the ground. find the horizontal and vertical components of this force
Answer:
The horizontal component of the force, Fₓ = 63.64 N
The vertical component of the force, [tex]F_y[/tex] = 63.64 N
Explanation:
Given;
magnitude of the force, F = 90 N
angle between the handle and the ground, θ = 45°
The horizontal component of the force, Fₓ = Fcosθ
Fₓ = 90 x cos45
Fₓ = 63.64 N
The vertical component of the force, [tex]F_y = Fsin \theta[/tex]
[tex]F_y[/tex] = 90 sin45
[tex]F_y[/tex] = 63.64 N
Therefore, the horizontal and vertical components of the force is 63.64 N.

In Europe, gas cost approximately €0.98 per liter. How many dollars($) per gallon is this? using a factor method
Answer:
€0.98 per liter = 4.377 doller per gallon
Explanation:
It is given that, In Europe, gas cost approximately €0.98 per liter. We need to convert it into dollars($) per gallon.
We know that, 1 euro = 1.18 United States Dollar
1 litre = 0.264172 US gallon
Cost of gas in Europe is €0.98 per liter.
[tex]0.98\ \text{euro/ liter}=\dfrac{0.98\times 1.18\ \text{doller}}{0.264172\ \text{gallon}}\\\\=4.377\ \text{doller/gallon}[/tex]

The news media, such as newspapers and television stations, carry current events worldwide. Explain how the way news travels is similar to the way a wave travels.
Answer:
A simile can be established with the news, where the fact that occurs is the matter of has some type of oscillation or disturbance, which occurs somewhere and is there, the news is the wave that carries the information of this fact the energy of the same to all points, therefore it is equivalent to a traveling wave.
Explanation:
Traveling waves are disturbances of the medium that are transmitted with a constant speed, where matter is subjected to oscillations around its equilibrium point, transporting only energy.
A simile can be established with the news, where the fact that occurs is the matter of has some type of oscillation or disturbance, which occurs somewhere and is there, the news is the wave that carries the information of this fact the energy of the same to all points, therefore it is equivalent to a traveling wave.
The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to a traveling wave.
What is a wave?A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify them.
Transverse and longitudinal are the two main forms.
The wave can be compared in the form of news as
The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to traveling. wave.
Traveling waves are medium disturbances that are conveyed at a constant pace, where matter oscillates around its equilibrium point, transferring only energy.
A parallel may be drawn with the news, where the fact that occurs is the issue of having some sort of oscillation or disturbance.
Hence the news is compared with the help by the help of energy and information.
