The false statement is B) Homolytic bond cleavage yields neutral radicals in which each atom gains one electron.

In homolytic bond cleavage, each atom retains one electron from the shared pair of electrons, resulting in the formation of two neutral radicals, where each atom retains its original number of electrons.

No atoms gain or lose electrons in this process.

In a homolytic bond cleavage, a covalent bond is broken, and the shared pair of electrons is split equally between the two atoms involved in the bond.

This results in the formation of two neutral radicals, with each atom retaining one of the electrons from the shared pair.

A radical is a chemical species characterized by the presence of an electron that is unpaired, meaning it does not have a partner electron with which it forms a complete pair. When a covalent bond is homolytically cleaved, each atom involved in the bond gains one electron, resulting in the formation of two radicals.

These radicals are highly reactive due to the presence of the unpaired electron, which makes them prone to participate in further chemical reactions.

It's important to note that in homolytic bond cleavage, there is no transfer of electrons from one atom to another.

Instead, the bond is broken in a way that allows each atom to retain one of the electrons, leading to the formation of two neutral radicals.

Therefore, statement B, which suggests that each atom gains one electron, is false.

Answer:

(a) the height of the diving board is 22.896 m

(b) the horizontal distance traveled by the girl is 7.02 m

(c) if she had just drop off the board, her time to drop to the water would have been longer.

Explanation:

Given;

initial speed of the girl, u = 3.9 m/s

time to hit the water, t = 1.8 s

(a) the height of the diving board is calculated as;

h = ut + ¹/₂gt²

h = (3.9 x 1.8)  +  ¹/₂ x 9.8 x 1.8²

h = 7.02 + 15.876

h =  22.896 m

(b) the horizontal distance traveled by the girl is calculated as;

X = ut

X = 3.9 x 1.8

X = 7.02 m

(c) if she just drop off the board, then the initial speed will be zero;

h = ut + ¹/₂gt²

h = 0 + ¹/₂gt²

2h = gt²

\(t^2 = \frac{2h}{g} \\\\t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2 \ \times\ 22.896 }{9.8} }\\\\t = 2.16 \ s\)

Thus, if she had just dropped off the board, her time to drop to the water would have been longer.

Simply put different aspects of the electromagnetic spectrum reflect differently. Certain chemicals will absorb different frequencies of light while reflecting others.

By knowing how intensity relates to distance, we will see that at 4 meters of the engine the intensity is 80.

The sound spreads in a solid angle like all waves, so the intensity of the sound will decrease with the distance squared, this means that:

\(I = \frac{P}{4*pi*r^2}\)

Where P is the sound power, we know that when the student is at 8m from the engine, the intensity measured is 20 (it does not tell the units) so we have:

\(20 = \frac{P}{4*3.14*(8m)^2} \\\\P = 20*4*3.14*(8m)^2 = 16,078.8 m^2\)

Now, if you move 4 meters closer to the engine, your new position will be:

r = 4m

Then we have:

\(I = \frac{16,078.8 m^2}{4*3.14*(4m)^2} = 80\)

The set {1,{2},{3}} contains three elements: 1, {2}, and {3}. The element {2} is a set that contains the element 2. However, the element {2} is not itself an element of the set {1,{2},{3}}.

To be an element of a set, an object must be contained directly within the set. In this case, the object {2} is not contained directly within the set {1,{2},{3}}. Instead, it is contained within the set {2}. Therefore, {2} is not an element of the set {1,{2},{3}}.

Here is another way to think about it. If we were to write out the set {1,{2},{3}} in list form, it would look like this:

Answer:

Approximately \(86.5\; {\rm V}\).

Explanation:

By Faraday's Law of Induction, the emf \(\epsilon\) induced in a coil would be proportional to the number of turns \(N\) in that coil and rate of change in magnetic flux through that coil \(d\Phi / d t\):

\(\displaystyle \epsilon = -N\, \frac{d\Phi}{dt}\),

In a transformer, the rate of change \(d\Phi / d t\) in magnetic flux is the same for both coils. Hence, the the emf induced in each coil would be directly proportional to the number of turns in each coil.

Let \(N_{P}\) and \(N_{S}\) denote the number of turns in the two coils. Let \(\epsilon_{P}\) and \(\epsilon_{S}\) denote the emf induced in the two coils.

\(\displaystyle \frac{\epsilon_{P}}{N_{P}} = \frac{\epsilon_{S}}{N_{S}}\).

\(\begin{aligned} \epsilon_{S} &= \frac{\epsilon_{P}\, N_{S}}{N_{P}} \\ &= (30.0\; {\rm V}) \, \frac{980}{340} \\ &\approx 86.5\; {\rm V}\end{aligned}\).

Answer:The continuity equation for a compressible liquid is a mathematical expression that relates the changes in fluid density, velocity, and volume to the changes in time. This equation can be written as:

∂ρ/∂t + (ρv)•∇ = 0

where:

ρ = fluid density

v = fluid velocity

∂/∂t = partial derivative with respect to time

∇ = del operator

The continuity equation expresses the principle of mass conservation, stating that the rate of change of fluid density in a fixed volume must be equal to the rate of flow of fluid into or out of that volume. This equation is commonly used in fluid dynamics to study the behavior of liquids and gases in various applications, such as in pipelines, pumps, valves, and compressors.

The net force on the box perpendicular to the floor is

∑ F[perp] = F[normal] - mg = 0

where mg is the weight of the box. Then

F[normal] = mg = 147 N

so that

F[friction] = 0.3 F[normal] = 44.1 N

The net force parallel to the floor is

∑ F[para] = F[applied] - F[friction] = ma

where a is the acceleration of the box. Then

F[applied] = (15 kg) a + 44.1 N

Then the work done by the applied force is

W[applied] = ((15 kg) a + 44.1 N) (1 m) = (15a + 44.1) J

We can't find the exact amount of work without any more information. If the box is pulled with constant speed, then a = 0 so the work would be 44.1 J.

Expression for rate law for first order kinetics is given by:

\(t=\frac{2.303}{k}\log\frac{a}{a-x}\)

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant  = x

a - x = amount left after decay process  = \(\frac{x}{16}\)

a) for calculating k

\(20=\frac{2.303}{k}\log\frac{x}{\frac{x}{16}}\)

\(k=\frac{2.303}{20}\log{16}\)

\(k=0.138years^{-1}\)

b) for calculating half life:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

\(t_{\frac{1}{2}}=\frac{0.693}{0.138years^{-1}}\)

\(t_{\frac{1}{2}}=5years\)

Thus its half life is 5 years

The mass flow rate of water is 0.08757 kg/s

mCp (T2 - T1) = Q =w

m x 1.015 (360-315) = 4000

m = 4000/ 1.015 x 10^3 x (360-315)

m = 0.08757 kg/s

The density of water at 68°F / 20°C has a flow rate in our example of about 998 kg/m3. However, as the density of water varies with temperature, salinity, and pressure, use our water density calculator if you want to be extremely accurate. 30.58 lbs/s of mass flow were shown by the gadget.

The switch that adjusts the magnetic field to be either nearly uniform or have a strong gradient will affect the current in the two coils differently.

When the magnetic field is nearly uniform at the center, the current in both coils will remain relatively unchanged. The uniform field will not induce any significant voltage in the coils, so the current will flow through them as usual.

However, when the magnetic field has a strong gradient, the current in the two coils will be affected differently. The rapidly changing field will induce a voltage in the coils according to Faraday's law of electromagnetic induction. This induced voltage will result in a change in the current flowing through the coils. The magnitude and direction of the induced current will depend on the specific characteristics of the coils and the magnetic field gradient.

In summary, the switch that changes the magnetic field from uniform to having a strong gradient will induce a change in the current flowing through the coils due to the induced voltage.

Mass is a fixed quantity of matter, while weight is the force exerted on a mass by gravity. Therefore, weight depends on the forces acting on a mass, specifically the gravitational force.

Mass and weight are not the same, but they are related because weight is proportional to mass. More specifically, weight is equal to the mass of an object multiplied by the acceleration due to gravity. Mass and weight are not related by speed or any other mathematical operation, and they are not inversely proportional or related by squaring.

Explanation:

Part A
Here, we have to find out the final displacement from the origin. In order to find the displacement, we have to find out the net distance travelled by the delivery truck.

First we will find the total distance covered in the north and south direction:21 blocks north, 27 blocks southSo, the net distance travelled in north-south direction = (21-27) blocks = -6 blocksNow, we will find the total distance covered in the east and west direction: 15 blocks east.

So, the net distance travelled in east-west direction = 15 blocks Net distance travelled = √(6² + 15²) ≈ 16 blocks. So, the final displacement from the origin (magnitude) is 16 blocks.

Part B

To find the final displacement from the origin (direction), we have to find the direction of the displacement. Here, the delivery truck travels 21 blocks north, 15 blocks east, and 27 blocks south.

So, the displacement vector has two components, i.e. one in north-south direction and another in east-west direction. Net displacement in east-west direction = 15 blocksAnd, net displacement in north-south direction = -6 blocks

Therefore, the angle of the displacement vector with the east direction can be found as shown below:θ = tan-1((-6)/15)≈ -22.6°The angle is negative because the vector is in the opposite direction to the east direction. Therefore, the final displacement from the origin (direction) is 23° west of the north direction (approximate to three significant figures).

Magnitude : The simple definition of magnitude is "distance or quantity." In the sense of motion, it depicts the absolute or relative direction or size of an object's movement. It is used to convey something's size or scope. In material science, extent by and large alludes to distance or amount.

Answer:

Kundan should sit at more that 2.5 meters from the location of the fulcrum on the side opposite to the side where Bijaya sits

Explanation:

The given parameters are;

The weight of Kundan, F₁ = 200 N

The weight of Bijaya, F₂ = 500 N

The distance of Bijaya from the fulcrum, d₂ = 1 m

Therefore, for Kundan to lift Bijaya, Kundan should sit at a location further than the point where both the moment of Bijaya and Kundan about the fulcrum are equal

Moment of a force, M = The magnitude of the force, F × The perpendicular distance to the point at which the force acts, d

At equilibrium, the sum of the clockwise moment = The sum of the anticlockwise moment

Taking the moment of Kundan as being in the anticlockwise direction and the moment of Bijaya as acting in the clockwise direction, we have;

F₁ × d₁ = F₂ × d₂

∴ 200 N × d₁ = 500 N × 1 m

d₁ = 500 N·m/(200 N) = 2.5 m

Therefore, when Kundan sits at the point d₁ = 2.5 m, away from the fulcrum on one side of the sea saw and Bijaya sits at the point 1 m from the fulcrum on the other side of the sea saw, both Kundan and Bijaya will have the same moment

For Kundan to lift Bijaya, therefore, Kundan as to sit at a point further than 2.5 m from the fulcrum on the opposite side of the fulcrum from Bijaya.
