Answer: a bridge suspended by cables

The fraction of kinetic energy which is transferred to the atomic nucleus is 30.3% and the final kinetic energy of the neutron is 2.93*10^-13.

An object's kinetic energy refers to the energy it has as a result of motion. After the job is finished, the object will be traveling at a new, constant speed because energy has indeed been transferred to it.

let the mass of neutron =m

Mass of neucleus= M

given: M=11.1m

by conservation of kinetic energy:

 fraction of energy that will be transferred to the nucleus = \(\frac{4mM}{(M+m)^{2} }\)

                                                                                                = 44.4/146.41

                                                                                                =0.303

let u be the initial velocities of neutron and nucleus

and v be the final velocities of neutron and nucleus

By conservation of linear momentum,

mu+Mu=mv+Mv

v(nucleus)=2*v(neutron)/12.1

the initial kinetic energy of neutron= 4.2*10^-13

so on solving the final kinetic energy of neucleus=1.27*10^-13

so,

final k.e.of neutron=4.2*10^-13 - 1.27*10^-13

                              = 2.93*10^-13

La presión se define como la fuerza ejercida por un cuerpo por unidad de área de sección transversal de ese cuerpo.

Presión = Fuerza / Área de sección transversal

Dada la masa de la bicicleta m = 620 kg

Peso de la bicicleta = mg = 620 * 9.8

Peso de la bicicleta = 6076N

Si la dimensión de su área de superficie es 0.5m por 0.6m, el área de la sección transversal será 0.6m * 0.5m = 0.30m²

Presión que ejerce la bicicleta en el suelo = 6076 / 0.30 = 20253.33N / m²

The Millenium Falcon is chased by the Imperial Forces. The ship is moving at a speed of 0. 587 c. Han Solo is shooting at the imperial fighters with his newly installed proton cannon purchased at the MSU Surplus Store for $20. 00 plus 6. 00% tax. The cannon emits protons at a speed of 0. 831 c with respect to the ship.

With the use of Relativistic velocity addition formula  we will find the velocity of proton in the resting frame of the movie audience in terms of the speed of the light when the cannon is shot in the forward direction
Formula is given as
v = (u+v')/(1+u*v'/\(c^{2}\))
Where
v = velocity of the protons in the resting frame of the movie audience

u = velocity of the Millennium Falcon with respect to the audience

v' = velocity of the protons with respect to the Millennium Falcon

c = speed of light

By putting all the values we get
v = (0.587c + 0.831c) / (1 + 0.587c*0.831c/\(c^{2}\))

v = (1.418c) / (1 + 0.486)

v = 0.942c

Hence, the velocity of the protons in the resting frame of the movie audience is 0.942 times the speed of light.

Balloon A is positively charged, and balloon C is negatively charged. If balloon A approaches balloon C, there will be an electrostatic force of attraction between them.

When two objects carry opposite charges, they exert an attractive force on each other. This force is known as the electrostatic force and follows Coulomb's law. According to Coulomb's law, the magnitude of the electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. In this scenario, since balloon A is positively charged and balloon C is negatively charged, they have opposite charges. Therefore, the electrostatic force between them will be attractive. The magnitude of the force depends on the charges of the balloons and the distance between them. It is important to note that without specific information about the charges of the balloons and their distance, it is not possible to determine the exact magnitude of the force. To calculate the force, you would need the values of the charges and the distance between the balloons.

Answer:

The magnitude of the boy's displacement is 24.698 paces which is in the direction of approximately 58.24° North of East

Explanation:

The given parameters are;

The distance West the boy on a treasure hunt walks = 12 paces

The distance North the boy on a treasure hunt then walks = 21 paces

The distance East the boy on a treasure hunt then walks = 25 paces

Writing the displacement in vector format, gives;

d = -12·i + 21·j + 25·i

Which gives

d = 13·i + 21·j

The magnitude of the boy's resultant displacement is given as follows;

\(\left | \mathbf{d} \right | = \sqrt{d_x^2 + d_y^2}\)

Where;

\(d_x = 13, \ d_y = 21\)

\(\left | \mathbf{d} \right | = \sqrt{13^2 + 21^2} = \sqrt{610} \approx 24.698 \ paces\)

The magnitude of the boy's displacement is 24.698 paces

The direction of the displacement is tan⁻¹(21/13) ≈ 58.24° North of East.

The magnitude of acceleration of the yo-yo during its fall and rise can be determined using the principles of rotational motion and torque.

(a) During the yo-yo's fall, it is subject to two forces: its weight (mg) and the tension in the string. The net torque acting on the yo-yo causes it to rotate and accelerate. The torque due to the weight can be calculated as the weight multiplied by the radius of the axle (2.77 cm). The torque due to the tension in the string can be calculated as the tension multiplied by the radius of the disks (27.7 cm).

To calculate the magnitude of acceleration during the fall, we need to sum up the torques and divide by the moment of inertia of the yo-yo. The moment of inertia for two uniform disks connected by an axle can be calculated as (1/2) * mass * (radius^2).

Once we have the moment of inertia and the net torque, we can use the equation τ = I * α, where τ is the net torque, I is the moment of inertia, and α is the angular acceleration. The angular acceleration is related to the linear acceleration by the equation α = a / r, where a is the linear acceleration and r is the radius of the axle.

(b) During the yo-yo's rise, the forces acting on it are the same as during the fall: its weight (mg) and the tension in the string. However, the direction of the net torque is opposite to that during the fall. Thus, the magnitude of acceleration during the rise can be calculated using the same principles as in part (a), but with the signs of the torques reversed.

It's important to note that the tension in the string changes during the yo-yo's motion, which affects the magnitude of acceleration. To accurately determine the tension, more information about the yo-yo's motion, such as the angular velocity or the length of the string, would be needed.

In summary, the magnitude of the acceleration of the yo-yo during its fall and rise can be calculated using principles of rotational motion, torque, and moment of inertia. The specific calculations require more information about the yo-yo's motion and the tension in the string.

In the dry and extremely hot conditions of Southern California during summer, at approximately 1 pm, one would expect to see that the stomata of plants are closed. This is because to avoid excessive water loss through transpiration, plants tend to close their stomata, which are tiny openings on the surface of leaves responsible for gas exchange. Closing the stomata helps to conserve water by reducing the loss of water vapor from the plant's leaves.

Stomata play a crucial role in gas exchange during photosynthesis. However, when plants are exposed to hot and dry conditions, the closure of stomata becomes essential to prevent excessive water loss. By closing their stomata, plants can reduce transpiration and conserve water. Transpiration is the process through which water vapor escapes from the plant through the stomata.

Closing the stomata helps in minimizing water loss by reducing the evaporation of water from the plant's leaves into the surrounding dry air. This is particularly important in drought conditions when water availability is limited. By conserving water, plants can better withstand the dry and hot environment.

While the closure of stomata helps in water conservation, it also has an impact on photosynthesis. When the stomata are closed, the exchange of gases, including carbon dioxide (CO2) for photosynthesis, is restricted. As a result, the rate of photosynthesis decreases. However, in extremely hot and dry conditions, the priority for the plant is to conserve water rather than carry out photosynthesis. Therefore, it is expected that the stomata will be closed to limit water loss, even though this reduces the availability of CO2 for photosynthesis.
