Electrons that are located in the outermost orbit in the Bohr model of a boron atom will be 3.

A nucleus with six neutrons and five protons makes up the Bohr model of boron. The K-shell and L-shell electron shells around the nucleus The valence electrons, which make up three of the electrons in the outermost shell of the Bohr diagram, are also present. The orbits of the electrons around the small nucleus are described by the Bohr model of boron.

It utilizes a number of different electron shells, including K, L, M, and N. The number of electrons that each shell can hold varies, with the shell closest to the nucleus having the least energy. The energy levels increase as the shell recedes more. According to the Bohr model, the electrons in an atom may be seen to orbit the nucleus in a variety of orbits with differing energies.

Answer:

use first equation of motion v=u+at..v is 0..since we have to take him to rest and u is 13.5

Explanation:

u = 13.5 m/s

a = - 2.5 m/s^2

v = u + at

0 = 13.5 - 2.5 * t

t (time to reach a complete halt) = 5.4 sec

Answer:

\(45m\)

Explanation:

Let \(V_0\) be the horizontal speed of the keys and D be the horizontal distance covered by the keys.

\(V_0= 8.0 \frac ms\)

\(D= 28 m\)

The initial velocity in the vertical direction is \(0\).

Let \(g\) be the acceleration due to gravity, which always acts vertically downwards, so, it will not change the horizontal direction of the speed, i.e. \(V_0\) will remain constant throughout the projectile motion.

Let \(t\) be the total time of flight in seconds. So,

\(D= V_0t\)

\(\Rightarrow 28=8t\)

\(\Rightarrow t=3 s \; \cdots (i)\)

Let \(H\) be the hight of the cliff.

Now, from the equation of motion

\(s=ut+\frac 1 2 at^2\;\cdots(ii)\)

Where is the displacement is the direction of force, is the initial velocity in the direction of force,   is the constant acceleration due to force and is the time of flight.

Here, , and  (negative sign is for taking the sigh convention positive in the direction as shown in the figure.)

From equation (ii)

\(-H=0\times t + \frac 1 2 (-g)t^2\)

\(\Rightarrow H= \frac 1 2 gt^2\)

Take \(g= 10 \frac m{s^2}\) and put the value of \(t\) from equation (i), we have

\(H=\frac 1 2 \times 10\times 3^2\)

\(\Rightarrow H= 45 m\).

Hence, the height of the cliff was \(45 m\).

The correct statement is "I only." One of the pre-loss objectives of risk managers is to meet any legal requirements the company may face.

The use of fire-resistive materials when constructing a building is an example of risk control. This is because risk control involves taking proactive steps to reduce the likelihood or severity of loss when an incident occurs. Fire-resistive materials are designed to withstand fire, and they are meant to slow down or contain the spread of fire in a building, thus reducing the risk of loss or damage.

In risk management, risk control is one of the four basic methods used to handle or mitigate risks. The other methods include risk transfer, risk avoidance, and risk retention. Risk transfer involves shifting the risk of loss to another party, such as through insurance or contract agreements. Risk avoidance involves eliminating the activity that could lead to loss or harm, while risk retention involves accepting the risk and dealing with any losses that may occur. As for the second question, the correct statement is "I only."

One of the pre-loss objectives of risk managers is to identify, assess, and evaluate potential risks that could negatively affect an organization. They also work to develop strategies to manage these risks and to ensure that the company is meeting any legal or regulatory requirements. On the other hand, one of the post-loss objectives of risk managers is to minimize the impact of losses that occur. They work to evaluate the effectiveness of the company's risk management strategies and to ensure that the company recovers from the loss as quickly as possible. Maximizing the risk manager's wealth is not a post-loss objective of risk managers.

Answer:

0.16Hz

Explanation:

Given that:

wavelength (λ) = 125 meters

speed (V) = 20 m/s

frequency (F) = ?

Recall that frequency is the number of cycles the wave complete in one second. And its value depends on the wavelength and speed of the wave.

So, apply the formula V = F λ

Make F the subject formula

F = V / λ

F = 20 m/s / 125 meters

F = 0.16 Hz

Thus, the frequency of the wave is 0.16 Hertz.

Answer:

Approximately \(4.50 \times 10^{11}\; {\rm s}\).

Explanation:

The speed of light is \(c \approx 3.00\times 10^{8}\; {\rm m\cdot s^{-1}}\).

Note that the standard unit of energy, joule, is a derived unit. In terms of the standard base units:

\(\begin{aligned}1\; {\rm J} &= (1\; {\rm N})\, (1\; {\rm m}) \\ &= (1\; {\rm kg \cdot m \cdot s^{-2}})\, (1\; {\rm m}) \\ &= 1\; {\rm kg \cdot m^{2} \cdot s^{-2}} \end{aligned}\).

Apply unit conversion and ensure that the unit of mass is in the standard unit kilogram (\({\rm kg}\)):

\(\begin{aligned} m &= 1\; {\rm g} \times \frac{1\; {\rm kg}}{10^{3}\; {\rm g}} &= 10^{-3}\; {\rm kg}\end{aligned}\).

Apply the equation \(E = m\, c^{2}\) to find the energy equivalent to \(m = 10^{-3}\; {\rm kg}\) of matter:

\(\begin{aligned}E &= m\, c^{2} \\ &= (10^{-3}\; {\rm kg})\, (3.00 \times 10^{8}\; {\rm m\cdot s^{-1}})^{2} \\ &= 9.00\times 10^{13}\; {\rm kg \cdot m^{2} \cdot s^{-2}} \\ &= 9.00\times 10^{13}\; {\rm J} \end{aligned}\).

Divide energy \(E\) by power \(P\) to find the duration \(t\) of the power consumption:

\(\begin{aligned} t &= \frac{E}{P} \\ &\approx \frac{9.00 \times 10^{13}\; {\rm J}}{200\; {\rm J \cdot s^{-1}}} \\ &= 4.50 \times 10^{11}\; {\rm s}\end{aligned}\).

In other words, the energy equivalent to \(1\; {\rm g}\) of matter could power this fridge for approximately \(4.50 \times 10^{11}\; {\rm s}\).

Answer:

If there were no transformation of energy in the world, everything would come to a standstill.

Explanation:

Energy is required for all processes and interactions to occur, including movement and chemical reactions. Without energy, matter would not be able to move or change in any way. This would mean that living organisms would not be able to survive, as they rely on energy to carry out metabolic processes and maintain their body's functions.

The sun would not shine, the wind would not blow and the water would not flow, as they are all driven by energy transformations. The weather would not change, and there would be no seasons. The temperature would not vary and the weather patterns would not change.

Machines and technology would not work, as they also rely on energy to operate. There would be no electricity, transportation, or communication. The economy would come to a standstill as all the industry, trade, and commerce would stop.

In short, without energy transformation, the world would be a static, lifeless place, and life as we know it would not be possible.

Explanation:

Vertical component = 250 sin30

250×1/2=125N

The work done by the applied force on the block against the frictional force is 15.75 J.

Work done is equal to product of force applied and distance moved.

Work = Force x Distance

Given is a 4 kg block is pushed 2m at an acceleration of 0.2 meter per second square up a vertical wall by constant force f applied at an angle of 37 degree with the horizontal if the coefficient of kinetic friction, μ between the block and the wall is 0.30.

From the equilibrium of forces acting on the block, we have

F - f = ma

where, F is applied force, f is frictional force, m is the mass and a is the acceleration.

Frictional force f =  μmgsinθ

Substitute the values, we get

Fcos(37) - μmgsin(37) = ma

Fcos(37) - (0.3)(4)(9.8)sin(37) = 4(0.2)

0.799F - 7.077 = 0.8

F = 9.86 N

Work done by the applied force is

W = Fdcosθ

W = 9.86 x 2 x cos(37)

W = 15.75 J

Thus, the work done by the applied force on the block against the frictional force is 15.75 J.

Answer:

Explanation:

The oly way we can figure this out is if the boy is pulling the sled at a constant velocity. If not, we need a value for acceleration, and you don't have that here. If the boy is pulling the sled at a constant velocity, then the value for acceleration is 0, making this a really simple problem. I'm going with that, since there is no way to answer you otherwise. If velocity is not constant, please either repost the question or put it in the notes section under the question as it stands. If acceleration is 0, then

F - f = ma becomes

F - f = m(0) which is

F - f = 0 and

F = f which says that the applied force is the same as the frictional force. We need then to find the frictional force, which has an equation of

f = μ\(F_n\) where normal force is the same as the weight of the 2 girls. We will find that, then:

Each girl's mass is different so the normal force/weight equation is

w = (30.0)(9.8) + (40.0)(9.8) to get

w = 290 + 390 and

w = 680. Plug that into the frictional force equation:

f = (.120)(680) so

f = 82N

The speed of light is 30,060,120.24048 m/s.

Explanation:

15000000 km into m

1 km = 1000m

15000000 km = 15000000 × 1000 m

= 15000000000m

speed = distance travelled / time taken

or, speed = 15000000000/499 m/s

so, speed = 30,060,120.24048m/s

To solve the problem we must know about the relationship between Speed, distance, and Time.

We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,

\(\rm{Speed = \dfrac{Distance}{Time}\)

The speed of the light is 30,060.12 km/sec.

Given to us

We know that speed can be described as,

\(\rm{Speed = \dfrac{Distance}{Time}\)

Therefore,

\(\text{Speed of light} = \dfrac{\text{Distance between the earth and the sun}}{\text{Time taken by the light to travel the distance}}\)

Substitute the value,

\(\text{Speed of light} = \dfrac{15,000,000\ km}{499\ seconds}\)

\(\text{Speed of light} = 30,060.12\ km/sec\)

Let F be the magnitude of the frictional force. This force performs an amount of work W on the bullet such that

W = -Fx

where x is the distance over which F is acting. This is the only force acting on the bullet as it penetrates the tree. The work-energy theorem says the total work performed on a body is equal to the change in that body's kinetic energy, so we have

W = ∆K

-Fx = 0 - 1/2 mv²

where m is the body's mass and v is its speed.

Solve for F and plug in the given information:

F = mv²/(2x)

Answer:

Average velocity is calculated by the formula V = D/t, where V equals the average velocity, D equals total displacement and t equals total time.

Explanation:

Average velocity is calculated by dividing your displacement (a vector pointing from your initial position to your final position) by the total time; average speed is calculated by dividing the total distance you traveled by the total time.

For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph). Average velocity, however, involves total displacement, instead of distance.

The three kinds of spectra can be used to determine different physical properties of the emitting matter.

Three kinds of spectrums :

1. Continuous spectrum: This type of spectrum is produced by a hot,          dense matter, such as a solid or dense gas.

It displays a range of wavelengths or colors without any gaps.

The physical property that can be determined using a continuous spectrum is the temperature of the emitting matter.

analyzing the peak wavelength and the distribution of energy, you can        calculate the temperature using Wien's Law.

2. Emission spectrum: This spectrum is produced by hot, low-density   gas.

It displays bright, distinct lines at specific wavelengths, which correspond to the energy levels of the emitting atoms.

The physical property that can be determined using an emission spectrum is the chemical composition of the emitting matter.

Each element has a unique set of emission lines, so you can identify the elements present in the matter by comparing its emission lines to known reference spectra.

3. Absorption spectrum: This spectrum is produced when light passes through a cooler, low-density gas, and the gas absorbs specific wavelengths, leaving dark lines at those positions.

The physical property that can be determined using an absorption spectrum is the chemical composition of the absorbing matter, similar to the emission spectrum.

By comparing the absorption lines to known reference spectra, you can identify the elements present in the matter.

Answer:

(1) 2 ohms

(2) 12 Volts Across each resistor

(3) I₁ = 3 A, I₂ = 2 A, I₃ = 1 A

Explanation:

From the question,

(1) Equilvalent Resistance (Rt) for parallel connection is

1/Rt =(1/R₁)+ (1/R₂) + (1/R₃)

Where R₁ = 4 ohms, R₂ = 6 ohms, R₃ = 12 ohms

1/Rt = 1/4 +1/6 +1/12

1/Rt = (3+2+1)/12

1/Rt = 6/12

1/Rt = 1/2

Rt = 2 ohms.

(2) Since the resistors are connected in parallel, They will have the same potential difference across them,

Hence the P.d across each resistor = 12 Volts.

(3) For R₁,

I₁ = V/R₁ = 12/4

I₁ = 3 A.

For R₂,

I₂ = V/R₂

I₂ = 12/6

I₂ = 2 A

For R₃,

I₃ = V/R₃

I₃ = 12/12

I₃ = 1 A
