(a) The fraction of neutron's kinetic energy transferred to the atomic nucleus is 0.09.

(b) The final kinetic energy of the neutron is 3.82 x 10⁻¹³ J.

The final velocity of the atom is calculated by applying the principle of conservation of linear momentum as follows;

initial momentum of the neutron = final momentum of the atom

m₁u₁  = m₂u₂

where;

The mass of the atomic nucleus = 11.1 m₁

u₂  = m₁u₁ / m₂

u₂  = m₁u₁ / (11.1 m₁)

u₂  = 0.09u₁

The initial kinetic energy of the neutron is calculated as;

K.Ei = ¹/₂m₁u₁²

The final kinetic energy of the atomic nucleus is calculated as;

K.Ef =  ¹/₂m₂u₂²

K.Ef =  ¹/₂(11.1 m₁)(0.09u₁)²

K.Ef = 0.09 (¹/₂m₁u₁²)

K.Ef = 0.09 (K.Ei)

The fraction of neutron's kinetic energy transferred to the atomic nucleus is calculated as;

= 0.09 (K.Ei) / K.Ei

= 0.09

= 9 %

The final kinetic energy of the neutron is calculated as follows;

K.E.f (neutron) = (1 - 0.09) x (4.2 x 10⁻¹³ J)

K.E.f (neutron) = 3.82 x 10⁻¹³ J

Answer:

a) We can use the following formula to calculate the acceleration of the object:

a = (v_f - v_i) / t

where a is the acceleration, v_f is the final velocity, v_i is the initial velocity, and t is the time interval. Substituting the given values, we get:

a = (90 m/s - 40 m/s) / (2 min * 60 s/min) = 0.83 m/s^2

The force applied causing it to speed up can be found using Newton's second law of motion:

F = m * a

where F is the net force, m is the mass of the object, and a is the acceleration. Substituting the given values, we get:

F = 0.05 kg * 0.83 m/s^2 = 0.042 N

Therefore, the force applied causing the object to speed up is 0.042 N.

b) The work done by this force can be calculated using the following formula:

W = F * d

where W is the work done, F is the net force, and d is the displacement of the object. The displacement of the object is given by:

d = 670 m

Substituting the given values, we get:

W = 0.042 N * 670 m = 28.14 J

Therefore, the work done by the force is 28.14 J.

c) The work done by friction can be calculated using the formula:

W_friction = F_friction * d

where W_friction is the work done by friction, F_friction is the force of friction, and d is the displacement of the object. The force of friction can be calculated using:

F_friction = μ * F_norm

where μ is the coefficient of friction and F_norm is the normal force. The normal force is equal to the weight of the object, which is given by:

F_weight = m * g

where m is the mass of the object and g is the acceleration due to gravity. Substituting the given values, we get:

F_weight = 0.05 kg * 9.81 m/s^2 = 0.49 N

The normal force is equal in magnitude to the weight of the object, so we have:

F_norm = F_weight = 0.49 N

Substituting the given coefficient of friction, we get:

F_friction = 0.34 * 0.49 N = 0.17 N

The work done by friction can now be calculated by substituting the values we have found:

W_friction = 0.17 N * 670 m = 113.9 J

Therefore, the work done by friction is 113.9 J.

d) The net work done can be calculated as the sum of the work done by the applied force and the work done by friction:

W_net = W_applied + W_friction

Substituting the values we have found, we get:

W_net = 28.14 J + 113.9 J = 142.0 J

Therefore, the net work done is 142.0 J.

To store temperature control for safety food (TCS) in refrigerators, salad bars, and pizza or sandwich prep units, the temperature must be kept at 41°F or colder.

Temperature control for safety (TCS) food is food that requires temperature control to limit the growth of bacteria or the production of toxins. TCS food includes most protein foods (such as meat, poultry, seafood, and eggs), dairy products, cooked vegetables and beans, and many ready-to-eat foods like sliced tomatoes, leafy greens, and deli meat.TCS foods must be kept out of the temperature danger zone to avoid bacterial growth and prevent the production of toxins. The temperature danger zone is between 41°F and 135°F, and it is the temperature range where bacteria grow most rapidly. To keep TCS foods safe and prevent foodborne illness, they must be kept at safe temperatures.TCS foods that are being refrigerated must be kept at 41°F or colder,

while TCS foods that are being hot-held must be kept at 135°F or hotter. When cooling TCS foods, they must be cooled from 135°F to 70°F within two hours and from 70°F to 41°F or colder within an additional four hours. This is known as the two-stage cooling process.It is important to regularly monitor the temperature of TCS foods using a calibrated thermometer to ensure they are being kept at safe temperatures. If the temperature is found to be out of range, corrective action must be taken immediately to prevent the growth of bacteria or the production of toxins and keep the food safe.

If the strong force was suddenly turned off throughout the universe, atoms would almost immediately disintegrate as the strong force is responsible for holding the nucleus of an atom together.

This would result in a release of energy as the protons and neutrons in the nucleus repel each other due to the electromagnetic force. The energy released would be so great that it would cause a massive explosion, similar to a nuclear explosion. Furthermore, the absence of the strong force would also affect the stability of neutron stars and supernovae, which rely on the strong force to maintain their structure. Overall, the absence of the strong force would result in a catastrophic and potentially apocalyptic scenario for the universe.

To calculate the current, we need to find the number of helium nuclei passing through a given point per unit time. The linear density of helium nuclei (denoted by λ) is given as 9.53 × 10^7 m^(-1), which represents the number of nuclei per meter.

Since the helium nuclei are accelerated to a speed of 2.09 × 10^6 m/s, each nucleus takes a time of Δt = 1/v to pass through a given point. Therefore, the number of nuclei passing through that point per unit time is λv.

The charge of each helium nucleus is 2e, where e is the elementary charge. Thus, the total charge passing through the point per unit time is given by Q = 2e × λv.

Finally, the current (I) is defined as the rate of flow of charge, so we can write I = Q/Δt = 2e × λv / (1/v) = 2eλv^2.

Plugging in the given values, we get I = 2 × (1.6 × 10^(-19) C) × (9.53 × 10^7 m^(-1)) × (2.09 × 10^6 m/s)^2 ≈ 4.00 A.

An aircraft's true airspeed (TAS) is affected by changes in the outside air temperature (OAT). When the OAT decreases, the air density increases, and this results in an increase in the aircraft's TAS. This is because as the air density increases, there are more air molecules available to create lift, and this reduces the amount of drag experienced by the aircraft.

In simple terms, if the aircraft is flying at a constant power setting and indicated altitude, and the OAT decreases, the TAS will increase. This means that the aircraft will cover more ground in a given amount of time, and the speedometer will indicate a higher speed.

It is essential for pilots to take into account changes in OAT when calculating their TAS, as this affects their fuel consumption, flight time, and overall performance. Understanding the relationship between OAT and TAS is crucial for safe and efficient flying.

The maximum speed at which the body can move before it slides off the platform is approximately 1.08 m/s.

To find the maximum speed at which the body can move before it slides off the platform, we need to find the maximum centripetal force that can be applied on the body. The centripetal force is given by the formula:

F = \(\frac {mv^2} {r}\)

where m is the mass of the body, v is its velocity, and r is its distance from the center of the platform.

The maximum force that can be applied is equal to the friction force, which can be calculated as:

\(f_{max} = f_{coefficient } \times N\)

where friction _(coefficient)= 0.60, and N is the normal force, which is equal to the gravitational force on the body, given by:

N = mg

where m is the mass of the body (200 g) and g is the acceleration due to gravity (9.8 m/s^2).

So, we can write the equation for the maximum friction force as:

\(f_{max} = friction_{coefficient} \times m g\)

Now, we can equate the maximum centripetal force and the maximum friction force:

\(\frac {m \times v^2} {r} = friction_{coefficient} \times m g\)

Solving for v, we get:

\(v = \sqrt{(friction_{coefficient} \times g \times r)}\)

Substituting the values, we get:

v =\(\sqrt{(0.60 \times 9.8 \times 0.20) }\)

=> \(\sqrt{(1.176) m/s\)

=> 1.08m/s

So, the maximum speed at which the body can move before it slides off the platform is approximately 1.08 m/s.
