An object's angular momentum won't change when it is rotating in a closed system without unbalanced forces, external forces, or torques. According to the law of conservation of angular momentum.
It is referred to as being in a state when there isn't any imbalanced force operating on any portion of the system or the system as a whole.The two forces are equal in strength and move in opposite directions, which causes them to balance one another. The book is in equilibrium and won't accelerate because there aren't any unbalanced forces operating on it.
What three things can an object do as a result of uneven forces?Due to unequal forces on the same side, an imbalanced force accelerates the item on which it is operating, changing its position, speed, or direction. An imbalanced force accelerates the item it is acting upon, shifting its location.

stars x and y are 5 au apart from each other. star x is 1.5 times as massive as star y. the center of mass of this system is au away from star x and au away from star y. question 14 options: 2;3 3;2 1;4 4;1
To find the center of mass of the system, we need to consider the masses and positions of the two stars.
Given:
Distance between stars x and y = 5 AU
Mass of star x = 1.5 times the mass of star y
Let's assume the distance of the center of mass from star x is d1, and the distance of the center of mass from star y is d2.
According to the principle of the center of mass, the center of mass of a system can be calculated using the formula:
d1 = (m1 * x1 + m2 * x2) / (m1 + m2)
d2 = (m1 * y1 + m2 * y2) / (m1 + m2)
where m1 and m2 are the masses of stars x and y, and x1, x2, y1, and y2 are their respective positions.
In this case, since star x is 1.5 times as massive as star y, we have:
m1 = 1.5m2
Therefore, the center of mass of this system is 3 AU away from star x and -3 AU away from star y.

DIDN'T GET WRONG BUT WANTED TO BETTER UNDERSTAND
2.5E-2 s^-1
Rate for compound 3 is 125 nM/s, and rate of product formation did not vary over time for first 5 minutes implies enzyme was saturated with substate.
Kcat=Vmax/[E]= 125 nM/s/(5.0 uM)= 2.5E-2 s^-1
The kcat for the reaction of the enzyme at pH 4.5 when no chloride is added and compound 3 is the substrate is 2.5E-2 s^-1. This value is calculated using the formula Kcat = Vmax / [E], where Vmax is the maximum velocity of the reaction, and [E] is the concentration of the enzyme.
In this experiment, the concentration of the enzyme is 5.0 uM, and the rate of product formation for compound 3 is 125 nM/s. As the rate of product formation did not vary over the first 5 minutes, it can be assumed that the enzyme was saturated with substrate. Using this information, the kcat can be calculated as:
Kcat = Vmax / [E]
= 125 nM/s / (5.0 uM)
= 2.5E-2 s^-1
Therefore, the kcat for the reaction at pH 4.5 when no chloride is added and compound 3 is the substrate is 2.5E-2 s^-1.

A man supports himself and the uniform horizontal beam pulling the rope with a force T.The weights of men and the beam are 883 N and 245 N respectively.Calculate the tension T in the rope and the forces exerted by the pin at A.
Answer:
T=502.5N
Ax=171.8N
Explanation:
The computation of the tension T in the rope and the forces exerted by the pin at A is shown below:
vertical forces sum = Ay + Tsin20 + T - 245 - 883 = 0
Now
horizontal forces sum = Ax - Tcos70
Now Moment about B
-Ay × 4.8 + 245 × 2.4 + 883 × 1.8=0
Ay=453.6N
Now substitute in sum of vertical forces T=502.5N
Ax=171.8N
a. The tension (T) in the rope is equal to 502.51 Newton.
b. The forces exerted by the pin at A is equal to 171.86 Newton.
Given the following data:
Weight of men = 883 N Weight of beam = 245 NTo calculate the tension (T) in the rope and the forces exerted by the pin at A:
First of all, we would determine the vertical force by taking moment about point B as shown in the diagram.
\(-A_y \times 4.8 + 883 \times 1.8 + 245 \times 2.4 =0\\\\-4.8A_y + 1589.4 + 588 =0\\\\4.8A_y= 3237\\\\A_y=\frac{2177.4}{4.8} \\\\A_y= 453.63 \;Netwon\)
The tension (T) in the rope would be calculated by the sum of the vertical component of forces, which is given by:
\(\sum F_x = A_y + Tsin20 + T - 245 - 883 = 0\\\\453.63 + 0.3420T + T -1128=0\\\\1.3420T = 1128-453.63\\\\1.3420T =674.37\\\\T =\frac{674.37}{1.3420}\)
Tension, T = 502.51 Newton.
To find the forces exerted by the pin at A, we sum the vertical component of forces, which is given by:
\(\sum F_y = A_x - Tcos70 =0\\\\A_x =Tcos70\\\\A_x = 502.51 \times cos70\\\\A_x = 502.51 \times 0.3420\\\\A_x = 171.86\;Newton\)

The type of extinguisher that is intended to be used on a Class B fire is the Aqueous film forming foam (AFFF) extinguisher. The AFFF extinguisher is the main answer to the question.
An Aqueous film forming foam extinguisher is designed to extinguish fires that are fueled by flammable liquids like oil, gasoline, or kerosene. This extinguisher works by covering the fuel source with a layer of foam that deprives the flames of oxygen. The foam also helps to cool the fuel, further limiting the spread of the fire.
There are different types of fires, and each requires a specific type of extinguisher. A Class B fire is fueled by flammable liquids, including gasoline, oil, and kerosene, among others. These fires can be extremely dangerous and difficult to extinguish, which is why it's important to use the right type of fire extinguisher.
The Aqueous film forming foam extinguisher (AFFF) is the most effective type of extinguisher for Class B fires. This type of extinguisher works by smothering the flames with a layer of foam that contains water and a special chemical agent. The foam creates a barrier that cuts off the fire's oxygen supply and prevents it from spreading. AFFF extinguishers are stored-pressure extinguishers, which means that the foam is already mixed with water and ready to use.
In conclusion, the Aqueous film forming foam extinguisher (AFFF) is the type of extinguisher intended to be used on a Class B fire. This type of extinguisher is highly effective in smothering flames and preventing the fire from spreading. It is essential to use the right type of extinguisher for the type of fire to prevent the fire from growing.

a man pushing a mop across a f loor causes it to undergo two displacements. the first has a magnitude of 150 cm and makes an angle of 1208 with the positive x axis. the resultant displacement has a magnitude of 140 cm and is directed at an angle of 35.08 to the positive x axis. find the magnitude
The magnitude of the second displacement (D2) is approximately 198.49 cm.
To find the magnitude of the second displacement, we can use the concept of vector addition. Given the magnitudes and angles of the two displacements, we can break them down into their x and y components and then add the corresponding components to obtain the resultant displacement.
Let's denote the first displacement as D1 and the second displacement as D2.
D1:
Magnitude: 150 cm
Angle with the positive x-axis: 120.8°
D2:
Magnitude: Unknown (let's denote it as D2mag)
Angle with the positive x-axis: 35.08°
To find the x and y components of D1, we use trigonometric functions:
D1x = D1 * cos(angle)
D1y = D1 * sin(angle)
D1x = 150 cm * cos(120.8°) ≈ -75 cm
D1y = 150 cm * sin(120.8°) ≈ 129.90 cm
Now, let's find the x and y components of the resultant displacement:
Resultant displacement (R):
Magnitude: 140 cm
Angle with the positive x-axis: 35.08°
Rx = R * cos(angle)
Ry = R * sin(angle)
Rx = 140 cm * cos(35.08°) ≈ 115.53 cm
Ry = 140 cm * sin(35.08°) ≈ 79.83 cm
Since we know that the resultant displacement is obtained by adding the two displacements together, we can write:
Rx = D1x + D2x
Ry = D1y + D2y
By substituting the known values, we get:
115.53 cm = -75 cm + D2x
79.83 cm = 129.90 cm + D2y
Simplifying:
D2x = 115.53 cm + 75 cm ≈ 190.53 cm
D2y = 79.83 cm - 129.90 cm ≈ -50.07 cm
Now, we can find the magnitude of the second displacement (D2) using the components:
D2mag = \(\sqrt{ (D2_x^2 + D2_y^2)\)
D2mag = \(\sqrt{190.53 cm)^2 + (-50.07 cm)^2)\) ≈ 198.49 cm
Therefore, the magnitude of the second displacement (D2) is approximately 198.49 cm.
