the wave model can correctly provide all of these, but the bohr model fails for one. which of the following is evidence that the bohr model is incorrect because it fails?

We can apply the de Broglie equation: = h/p, where h is the Planck constant (6.626 x 10-34 J.s), p is the momentum, and is the wavelength. P = h/ = (6.626 x 10-34 J.s)/(2.0 x 10-9 m) = 3.313 x 10-25 kg.m/s is the result of solving for p.

Using the de Broglie relation between the momentum p and the wavelength of an electron (=h/p, where h is the Planck constant), the wavelength of an electron is computed for a given energy (accelerating voltage).

To get the electron's wavelength, use the de Broglie wave equation, hmv.

Part A: -2513.7 rev/s²Part B: 1082.3 ftPart C: 12988 in (rounded to the nearest inch).The solution to the problem is shown below:

Part A

The initial speed of the blade when it's shut off = 48300 rpm (revolutions per minute)

The final speed of the blade when it comes to rest = 0 rpm (revolutions per minute)The time it takes for the blade to come to rest = 2.00 s

The angular acceleration of the blade can be determined by using the formula below:

angular acceleration (α) = (ωf - ωi)/t

where,ωi = initial angular velocity of the blade

ωf = final angular velocity of the bladet

= time taken by the blade to come to restSubstituting the given values in the above formula, we get:

α = (0 - 48300 rpm)/(2.00 s)

= -24150 rpm/s

The negative sign indicates that the blade's angular velocity is decreasing.Part BThe distance traveled by a point on the rim of the blade during deceleration can be determined by using the formula for displacement with constant angular acceleration:

θ = ωit + (1/2)αt²

where,θ = angular displacement of a point on the rim of the blade during deceleration

ωi

= initial angular velocity of the blade

= 48300 rpm

= 5058.8 rad/st

= time taken by the blade to come to rest

= 2.00 sα

= angular acceleration of the blade

= -24150 rpm/s

= -2513.7 rad/s²

Substituting the given values in the above formula, we get:

θ = (5058.8 rad/s)(2.00 s) + (1/2)(-2513.7 rad/s²)(2.00 s)²

= 8105.3 rad

≈ 1298.8 revolutions

The distance traveled by a point on the rim of the blade during deceleration can be calculated using the formula for arc length of a circle:

S = rθwhere,'

r = radius of the blade = 10.0 in

S = distance traveled by a point on the rim of the blade during deceleration

S = (10.0 in)(1298.8 revolutions)

= 12988 in

≈ 1082.3 ft Part C

The magnitude of the net displacement of a point on the rim of the blade during deceleration is the same as the distance traveled by a point on the rim of the blade during deceleration.

S = 1082.3 ft (rounded to the nearest inch)

Explanation:

Average velocity = (change in position) / (change in time)

Therefore, (18-3) / 2.5 = 6

The average velocity of the shopping cart is 8.4 meters per second, directed towards the east.

To find the average velocity of the shopping cart, we'll use the formula for average velocity:

Average velocity = (change in displacement) / (change in time)

The change in displacement is the difference between the final position and the initial position of the shopping cart. Since the cart moves from 3.0m west of the flagpole to 18.0m east of the flagpole, the change in displacement will be:

Change in displacement = 18.0m - (-3.0m) = 18.0m + 3.0m = 21.0m

Now, we'll calculate the average velocity:

Average velocity = (21.0m) / (2.5s) = 8.4 m/s

Hence, the average velocity of the shopping cart is 8.4 meters per second, directed towards the east.

External locus of control

Explanation:

External locus of control is an attitude people possess that makes them attribute their failures or successes to factors other than themselves. The opposite of this type of attitude is the Internal locus of control where the individuals take responsibility for the outcomes of their actions whether good or bad. One good thing about the external locus of control is that when the individuals with this characteristic record successes, they attribute it to others and this presents them as people with team spirit. However, when they record failures, they do not want to take the blame, but rather attribute it to others.

Fred exhibits an external locus of control because he attributed his speeding to other factors like the road signs and GPS instead of fully admitting that it was his fault.

Friction is a force between two surfaces that are sliding, or trying to slide, across each other.  Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced.

A 1000 kg steel beam that is being supported by two ropes is a common example of a static equilibrium problem in physics.

When the beam is not moving, the net force acting on it must be zero, and the sum of the torques acting on it must also be zero. Since the beam is being supported by two ropes, the tension in each rope must be equal to half of the weight of the beam, which is 5000 N. This means that the total upward force acting on the beam is 10000 N, which is equal to the weight of the beam. To ensure that the beam remains in static equilibrium, the two ropes must be positioned such that the torques they produce are equal and opposite. The position and angle of the ropes can be calculated using the principles of torque and equilibrium.

The semicircular canals are specialized to assess rotational acceleration of the head, while the otolith organs are specialized to detect linear acceleration and static position of the head relative to the gravitational axis. The semicircular canals contain fluid-filled channels arranged in three perpendicular planes, allowing them to detect angular movements of the head. On the other hand, the otolith organs consist of small calcium carbonate crystals suspended in gelatinous fluid, which respond to linear accelerations and changes in head position relative to gravity.

The semicircular canals are responsible for detecting rotational acceleration of the head. They are three fluid-filled canals positioned in different planes: the horizontal canal, anterior (superior) canal, and posterior (inferior) canal. Each canal has a bulge at one end called the ampulla, which contains hair cells that detect fluid movement. When the head rotates, the fluid within the canals also moves, bending the hair cells and signaling the brain about the rotational acceleration.

The otolith organs, consisting of the utricle and saccule, are specialized in detecting linear acceleration and static position of the head relative to the gravitational axis. These organs contain small calcium carbonate crystals called otoliths that are embedded in a gelatinous layer. When the head accelerates linearly or changes position relative to gravity, the otoliths move, causing the gelatinous layer to shift and stimulating the hair cells. This signals the brain about changes in linear acceleration and head position, including tilting or linear movements such as walking or riding in a vehicle.

In summary, the semicircular canals are designed to detect rotational acceleration, while the otolith organs are specialized in detecting linear acceleration and static position changes of the head relative to the gravitational axis.
