The controversial psychological study of prison life that took place in 1971 is known as the Stanford Prison Experiment. It was conducted by psychologist Philip Zimbardo and his team at Stanford University to examine how individuals adapt to the roles of prisoners and prison guards in a simulated prison environment.

The study involved 24 male college students who were randomly assigned to either the role of prisoner or guard. The experiment quickly spiraled out of control as the guards began to abuse their power, and the prisoners became increasingly submissive and depressed. The guards used psychological tactics such as humiliation, sleep deprivation, and even physical punishment to maintain their authority over the prisoners.

The study was meant to last for two weeks, but it was terminated after just six days due to the extreme and abusive behavior of the guards. The Stanford Prison Experiment remains controversial due to ethical concerns about the mistreatment of the participants and the potential long-term psychological effects on those who took part.

The study has had a significant impact on the field of psychology and has raised important questions about the ethics of conducting psychological research. It has also shed light on the dangers of group dynamics and how individuals can be easily influenced by social roles and situations.

Explanation:

The maximum height that the orange will reach is 12.18 m.

When an object is thrown at an angle from the horizontal direction, the object is said to be in projectile motion.

You throw an orange out a window at a height of 12.00 meters upwards at an angle of 32° to the horizontal at a velocity of 3.5 m/s.

If u is the initial speed, the maximum height of the ball from the point of throwing is

H = u² sin²θ / 2g

Put the values, we get

H = 3.5² sin²32° / (2x9.81)

H = 0.1753 m

So, the maximum height calculated from the ground is

12 + 0.18 = 12.18 m

Thus ,the maximum height that the orange will reach is 12.18 m.

Answer:

c. Y

Explanation:

Newton's third law of motion states that action and reaction are equal and opposite. Hence for every action, there is an equal and opposite reaction.

Considering the system of forces shown in the image, W and Y are  opposite forces. When the driver slams on the brakes, he will be pushed forward towards the windscreen. The force Y exerted by the seat belt keeps him on the drivers seat by moving him backwards towards the seat.

The electric charge on the rod is no longer separated.

If the magnetic field is parallel to the position of the exposed surface the magnetic flux produced will be zero if the magnetic field is non-zero. If a charged particle moving parallel to the magnetic field has a velocity parallel to the magnetic field, then the force is zero In the above case the velocity is parallel to the magnetic field lines, so the magnetic force is zero.

Induced currents can be created by changing the strength of the magnetic field changing the size of the wire loop, or changing the direction of the wire loop. The main difference between magnetic flux and flux density is that magnetic flux is a scalar quantity whereas flux density is a vector quantity. Flux is the scalar product of flux density and area vector.

To observe the first-order diffraction maximum at 12.6° for a crystal with a spacing between planes of atoms of 0.250 nm, an X-ray wavelength of approximately 0.141 nm is used.

The diffraction of X-rays by a crystal occurs when the spacing between adjacent planes of atoms in the crystal is comparable to the wavelength of the X-rays. This phenomenon is described by Bragg's law, which states that constructive interference occurs when the condition nλ = 2d sinθ is satisfied, where n is the order of the diffraction, λ is the wavelength of the X-rays, d is the spacing between planes of atoms, and θ is the angle of diffraction.

In this case, the first-order diffraction maximum is observed at an angle of 12.6°, and the spacing between planes of atoms is 0.250 nm. To find the wavelength of the X-rays, we can rearrange Bragg's law as λ = 2d sinθ / n.

Plugging in the values, we have λ = 2 * 0.250 nm * sin(12.6°) / 1, which simplifies to approximately 0.141 nm.

Therefore, the wavelength of the X-rays used to observe the first-order diffraction maximum is approximately 0.141 nm.

Answer:

Energy required = 3169.34 Joules.

Explanation:

The quantity of energy (Q) required can be determined by;

Q = mcΔθ

Where: m is the mass, c is the specific heat and Δθ is the change in temperature.

But, m = 96.7 kg, c = 0.874 J/(kg\(^{o} C\)), \(T_{2}\) = \(69.2^{o}\) and \(T_{1}\) = \(31.7^{o}\).

So that,

Q = mc(\(T_{2}\) - \(T_{1}\))

   = 96.7 x 0.874 x (\(69.2^{o}\) - \(31.7^{o}\))

  = 96.7 x 0.874 x 37.5

  = 3169.3425

Q = 3169.34

   = 3.2 KJ

The amount of energy required is 3169.34 Joules.

No, after an alpha particle leaves the nucleus, it would not speed up because it has already been accelerated to its maximum velocity while it was inside the nucleus.

The alpha particle is emitted from a nucleus due to the process of radioactive decay, where the unstable nucleus emits an alpha particle to become more stable. During its formation, the alpha particle gains energy from the decay process, which causes it to move away from the nucleus. This energy is typically in the form of kinetic energy, which is the energy associated with the motion of an object.

Once the alpha particle leaves the nucleus, it travels at a constant velocity, which is determined by its initial kinetic energy and the resistance it encounters from the surrounding environment. This resistance is primarily due to the presence of other particles in the surrounding medium, such as air molecules or other atoms, which can cause the alpha particle to lose some of its kinetic energy through collisions.

Therefore, the alpha particle will not speed up after leaving the nucleus because it has already reached its maximum velocity inside the nucleus. However, it may lose some of its kinetic energy due to collisions with other particles, which could cause it to slow down over time.

To test the circuit breaker's tripping behavior, you can perform an overload test.

The following are the procedures for testing the circuit breaker:

Inspection:

Examine the circuit breaker for any visual harm or defects.

Ensure that all screws and terminals are secure and free of debris.

Continuity:

Use a multimeter to check the circuit breaker's continuity.

Ensure that there is continuity between the input and output wires of the circuit breaker and that the multimeter's resistance reading is zero when the breaker is closed.

Load:

Examine the circuit breaker's load-carrying capacity.

To do so, use a power source that is within the circuit breaker's current range and attach the circuit breaker to it.

As a result, the power source's current would flow through the circuit breaker.

Observe the tripping behavior:

After the power source has been connected, increase the current gradually to see if the circuit breaker trips at the appropriate value.

To do this, use a variable resistor or a load bank device to regulate the current flowing through the circuit breaker.

To determine which zodiacal constellations are visible in the western sky at 6 am on January 25, refer to the star finder and locate the corresponding positions on the celestial map.

The star finder is a helpful tool for locating celestial objects and obtaining information about the night sky. To use the star finder effectively, it should be held overhead with the compass points aligned to match the actual compass points. Keep in mind that east and west may appear reversed when looking down at the star finder.

The star finder consists of an open ellipse representing the sky for a specific time and date. The edges of the ellipse correspond to the observer's horizon. East and west are not located at the midpoint along the elliptical horizon due to the distortion caused by representing a three-dimensional hemisphere on a flat page. The east and west cardinal points are positioned north along the ellipse from their respective midpoints.

Locating the zenith is essential, as it is directly overhead for all observers and remains stationary. To find the zenith, tape both ends of a string between the north and south points on the star finder, spanning the entire visible sky. Mark a dot on the string midway between the northern and southern horizons using an ink pen. This dot represents the zenith.

By using the star finder and aligning it with the correct date and time, you can identify the zodiacal constellations visible in the western sky at 6 am on January 25. Simply locate the corresponding constellations on the star finder and observe their positions in the western region of the celestial map.

The statement that describes energy of the roller coaster as it slows down while travelling to the top of the coaster is 'The cart loses kinetic energy and gains potential energy.'

Consider three roller coaster points that are each at a different height from the ground. If we disregard all frictional and drag forces and focus just on the conservative forces acting on the roller coaster car, we may assume that all kinetic and potential energy is conserved. As a result, energy only transforms from one form to another.

When the roller coaster vehicle hits the bottom, it will have reached its maximum level of kinetic energy since all of the gravitational potential energy has been transformed into kinetic energy.

At the top of the roller coaster, the object has its maximum gravitational potential energy and none at all (assumed there is no velocity). As the object begins to fall to the bottom, its gravitational potential energy falls and its kinetic energy increases.

Hence, as the cart reaches the top, it slows down because it loses kinetic energy and gains potential energy.
