Answer: The whole of it was owned originally by the lord of the manor. He lived in the big house called the manor house. Attached to it were many acres of grassland and woodlands called the park. These were the "demesne lands" which were for the personal use of the lord of the manor.

The lord of the manor previously owned the entire property. He resided in the substantial home known as the manor house.

Thus, The park, which covered many acres of grassland and trees, was connected to it. These "demesne lands" belonged to the lord of the manor and were used exclusively for his exclusive purposes.

The word "manor" is derived from the Old French word "manoir," which means "dwelling place," but a manor isn't just any old house.

The homes and grounds of the nobility were referred to as manors back when people still had titles of nobility. expressing to someone that his home is a manor is the equivalent of expressing that it is so lavish and beautiful that it could have belonged to a lord.

Thus, The lord of the manor previously owned the entire property. He resided in the substantial home known as the manor house.

The sound pressure level produced within the roof void as a result of the plant room noise is calculated to be 48 dB.

To determine the sound pressure level in the roof void, we utilize the sound reduction index of the plant room wall and the sound pressure level in the plant room. The formula used for this calculation is L2 = L1 - R, where L2 represents the sound pressure level in the roof void, L1 denotes the sound pressure level in the plant room, and R signifies the sound reduction index of the plant room wall adjoining the roof void. Given that the sound pressure level in the plant room is 61 dB and the sound reduction index of the plant room wall is 13 dB, we substitute these values into the formula to find the sound pressure level in the roof void:

L2 = 61 dB - 13 dB

L2 = 48 dB

Hence, the sound pressure level produced within the roof void as a result of the plant room noise is determined to be 48 dB. To further reduce the sound pressure level from the plant room to the adjacent rooms, there are several recommended strategies. One approach is to improve the sound insulation of the common wall between the plant room and the adjacent rooms. This can involve increasing the sound reduction index of the wall by adding sound-absorbing materials or panels, or enhancing the sealing of any gaps or openings to minimize sound leakage.

An electric current is a flow of charge.

Electric current refers to the movement of electric charge in a conductor. It is the flow of charged particles, typically electrons, through a conductor. Electric current is measured in units of amperes (A), which represents the rate at which charge flows. One ampere is equivalent to one coulomb of charge passing through a point in one second.

The other statements mentioned are not completely accurate:

   The movement of electrons at near the speed of light is not a complete definition of electric current. While electrons do indeed move in electric circuits, their speed is typically much slower than the speed of light.

   The electrical equivalent of gravitational potential difference is voltage or electric potential difference. It is related to electric current but not the same thing.

   Electric current is not measured in joules per coulomb. Joules per coulomb is the unit for electric potential or voltage. Electric current is measured in amperes (A), as mentioned earlier.

The question should be:

The unknown noble gas is argon. Argon is the third most abundant gas in Earth's atmosphere, making up around 0.94% of the total atmosphere.

It is also the most abundant noble gas, making up around 1.3% of the atmosphere. Argon is an odorless, colorless, and tasteless gas that is slightly heavier than air.

It is nontoxic and nonflammable. Argon has a low thermal conductivity, so it is often used as an inert gas shield in welding and other high-temperature processes. In this case, it took 151 seconds for the same amount of argon to effuse from the container, compared to 74 seconds for neon.

This indicates that argon has a much lower effusion rate than neon and is therefore a different gas.

Explanation:

According to the law of conservation of energy, the energy can neither be created nor destroyed.

Answer:

The answers to your questions are given below

Explanation:

A. Definition of momentum.

Momentum of an object can be defined as the product of the mass of the object and its velocity. Mathematically, it expreessed as:

Momentum = mass x Velocity

From the above equation, we can derive the SI unit of momentum as follow:

Mass is measured in Kilogram (Kg)

Velocity is measured in meter per second (ms¯¹).

Momentum = mass x Velocity

Momentum = Kg x ms¯¹

Momentum = Kg•ms¯¹

Therefore, the SI unit of momentum is Kg•ms¯¹.

Bi. Determination of the force of the body from O to A.

Mass (m) = 5 kg

Velocity (v) = 40 ms¯¹

Time (t) = 2 secs.

Force (F) =?

Next, we shall determine the acceleration of the body.

Acceleration (a) = Velocity (v) /Time (t)

a = v /t

Velocity (v) = 40 ms¯¹

Time (t) = 2 secs.

Acceleration (a) =.?

a = v/t

a = 40/2

a = 20 ms¯²

Now, we can obtain the force as follow:

Mass (m) = 5 kg

Acceleration (a) = 20 ms¯²

Force (F) =?

Force (F) = mass (m) x Acceleration (a)

F = ma

F = 5 x 20

F = 100 N

Therefore, the force of the body from O to A is 100 N.

Bii. Determination of the force of the body from B to C.

Mass (m) = 5 kg

Velocity (v) = 40 ms¯¹

Time (t) = 10 – 6 = 4 secs.

Force (F) =?

Next, we shall determine the acceleration of the body.

Acceleration (a) = Velocity (v) /Time (t)

a = v /t

Velocity (v) = 40 ms¯¹

Time (t) = 4 secs.

Acceleration (a) =.?

a = v/t

a = 40/4

a = 10 ms¯²

Now, we can obtain the force as follow:

Mass (m) = 5 kg

Acceleration (a) = 10 ms¯²

Force (F) =?

Force (F) = mass (m) x Acceleration (a)

F = ma

F = 5 x 10

F = 50 N

Therefore, the force of the body from B to C is 50 N.

Explanation:

First we have to descompose velocity, and get Velocity of X and Y side:

Vx = V * cos 30°

Vx = 3 m/s * 0,866...

Vx = 2,598 m/s

Vy = V * sen 30°

Vy = 3 m/s * 0,5

Vy = 1,5 m/s

Lets calculate time of fly:

Firat, lets calulate up time:

uT = (Fv - Iv) / g

uT = (0 m/s - 1,5 m/s) / -9,8 m/s^2

uT = -1,5 m/s / -9,8 m/s^2

uT = 0,15 s

Like up time is equal to down time, time of fly will be:

T =uT + dT

T = 0,15 s + 0,15 s

T = 0,3 s

Now for calculate how far will reach, lets aplicate the formula:

d = Vx * T

d = 2,598 m/s * 0,3 s

d = 0,779 meters

Will reach 0,779 meters

When a light bounces off the surface of a metal cup and shines in Harold's eyes, the light waves undergo reflection. Reflection occurs when a wave encounters a boundary between two media and bounces back into the original medium.

When a light wave strikes the surface of the metal cup, some of the energy from the light is absorbed by the metal, causing electrons in the metal to become excited and move to higher energy levels. These excited electrons then release the energy they have absorbed by emitting new light waves, in a process called reflection. The reflected light waves bounce off the surface of the metal cup in many different directions, including towards Harold's eyes. When these waves enter Harold's eyes, they stimulate the cells in his retina, which sends electrical signals to his brain. His brain then processes these signals as visual information, allowing him to see the cup and the reflected light.

The gravitational force that exerts on the outer out in space is 1.73 ×\(10^{-7}\)N.

Gravitational force:

The force of gravity or gravitational force pulls objects with mass towards each other. The gravitational force between two objects can be calculated as a function of the product of their masses (M and m), the square of the distance between them(r), and the universal gravitational constant.

The formula is:

F = G Mm/r²

Let us assume that g = 10 m/s².

M = 11000/ 10 = 1100kg

m = 3400/10 = 340kg

The distance was given:

r = 12m

We can look up a value of G:

G = 6.674 ×\(10^{-11}\) m³ / kgs²

F = 6.674 \(10^{-11}\) ( 1100 × 340)/ 12²

  = 17333.86 ×\(10^{-11}\)

  = 1.73×\(10^{-7}\)N

Therefore the gravitational force is 1.73 ×\(10^{-7}\)N.

The rate of decomposition for hydrogen peroxide, when [H₂O₂] is 0.882 M, can be expected to increase. This is because as the concentration of H₂O₂ increases the number of molecules that are present in a solution increases.

This increase results in more molecules interacting with each other, which in turn increases the chances of a successful reaction. At this concentration, the reaction rate would be higher due to the increased number of reaction sites. This is supported by the fact that when a reaction takes place, the reaction rate typically increases with increasing concentration.

Additionally, the additional molecules will increase the number of collisions which will then result in more successful reactions due to the greater energy of collision. Consequently, the reaction rate would be expected to increase when [H₂O₂] is 0.882 M.

Explanation:

Amplitude begins at 9 cm, \(A_0 = 9 cm\)

The amplitude decreases by 7% (0.07) each second

The amplitude function can then be modeled as:

\(A(t) = A_0(1 - 0.07)^t\\A(t) = 9(0.93)^t\)

The spring oscillates 15 times each second, the period of oscillation (time to make 1 oscillation) will therefore be calculated as:
