Within how many hours must cooked tcs food be cooled from 135 to 70.
TCS food must be cooled from 135 °F to 70 °F in two hours . Milk and egg are the example of the tcs food.
What is temperature?Temperature directs the hotness or coldness of a body. Faster the motion of particles, more the temperature.
Raw, cooked, or partially cooked animal products such as eggs, milk, meat, or fowl. Rice, potatoes, and pasta are examples of cooked plant-based foods.
Raw seed sprouts, sliced melons, cut tomatoes, and cut leafy greens are examples of plant-based foods.
TCS food must be cooled from 135 °F to 70 °F in two hours and to 41 °F or below in six hours.

A 24 volt battery is connected to a circuit with a 4- light bulbs that are connected in series. Resistance of each light bulb is 3 Ohms, a) What will be the current in the circuit
Answer:
Current = 2 amps
Explanation:
Remark
The voltage of the circuit is 24 volts.
The Resistance Series circuit is
Rt = B1 + B2 + B3 + B4B1 = B2 = B3 = B4 = 3 ohmsRt = 4*3 ohms = 12 ohms (each bulb has a resistance of 3 ohms each and there are four of them)Givens
E = 24 volts
R = 12 ohms
Formula
E = I * R where
E = voltageR = resistanceI = CurrentSolution
24 volts = 12 * I Divide by 12
24/12 = I
I = 2 amperes.

Which transition by an electron will release the greatest amount of energy? a b c d
The electron of orbital a by transition will release the greatest amount of energy.
What is transition energy?Atomic electron transition is a change (or jump) of an electron from one energy level to another within an atom or artificial atom.
It appears discontinuous as the electron "jumps" from one quantized energy level to another, typically in a few nanoseconds or less.
It is also known as an electronic (de-)excitation or atomic transition or quantum jump.
Electron transitions cause the emission or absorption of electromagnetic radiation in the form of quantized units called photons. Their statistics are Poissonian, and the time between jumps is exponentially distributed.
The damping time constant (which ranges from nanoseconds to a few seconds) relates to the natural, pressure, and field broadening of spectral lines.
The larger the energy separation of the states between which the electron jumps, the shorter the wavelength of the photon emitted.

Use the drop-down menu to answer the question. a student is going to produce static charge in a glass rod by rubbing it with a piece of silk. which method of transferring charge does this image illustrate?
Answer:
The second answer is friction. In other words the second answer.
Explanation:
The correct answer to the question is Friction. Friction is responsible to produce a static charge in a glass rod by rubbing it with a piece of silk.
What is friction?Before answering this question, first we have to understand the process of charging a body by friction.
There are generally three modes of charging a body which are known as friction, induction and conduction respectively.
Friction: Friction is the mode of charging a body by direct contact through rubbing with another substance.
In this process, a low electron affinity substance is rubbed with a high electron affinity substance. The low electron affinity substance will lose electron, and acquires positive charge.
On the other hand, the high electron affinity substance will gain electrons, and gets negatively charged .
Hence, there is actual transfer of electrons from one body to another body in the process of charging a body through friction.
As per the question, the glass rod is rubbed with silk. Due this rubbing,static electricity will be developed on the glass rod and silk.
Hence, it is obvious that the glass rod gains static charge due to the process of friction.

A man lifts a 120 kg barbell 2 m above the ground . What is the gain in gravitational PE of the barbell?
Answer:
2,352 Joules
Explanation:
At the ground, the barbell has a classical mechanical energy value of zero. There is no classical kinetic or potential energy for the barbell. The moment the man starts to lift the barbell, he does work on the barbell and transfers kinetic energy to it due to the motion. At its maximum height where the man lifts the barbell to a stop, the kinetic energy is zero because it transformed into gravitational potential energy stored in the gravitational field. Our reference point for potential was defined to be zero at the floor, therefore we can say that the gravitational potential energy at 2 meters is:
[tex]U=mgh=(120kg)(9.8m/s^2)(2m)=2,352J[/tex]

Which event is part of a covection current in the air?
Answer:
As you must know, Convection Current is the transfer of heat by actual movement of molecules from a hot to cold place due to difference in densities. Thus, the phenomenon of convection current is also observed in nature, for example the Land and Sea Breezes help in keeping the temperature moderate in coastal areas. Convection current in air also helps the birds and gliders to stay in air for a long period.

parallel connection:Advandages: 1. Every unit that is connected in a parallel circuit gets equal amount of voltage.2. It becomes easy to connect or disconnect a new element without affecting the working of other elements.3. If any fault happened to the circuit, then also the current is able to pass through the circuit through different paths.Disadvantages: 1. It requires the use of lot of wires.2. We cannot increase or multiply the voltage in a parallel circuit.3. Parallel connection fails at the time when it is required to pass exactly same amount of current through the units.series connection:Advantages: 1. Series circuits do not overheat easily. This makes them very useful in the case of something that might be around a potentially flammable source, like dry plants or cloth.2. Series circuits are easy to learn and to make. Their simple design is easy to understand, and this means that it’s simple to conduct repairs .3. we can add more power devices, they have a higher output in terms of voltage .4. The current that flows in a series circuit has to flow through every component in the circuit. Therefore, all of the components in a series connection carry the same current.Disadvantages: 1.If one point breaks in the series circuit,the total circuit will break.2. As the number of components in a circuit increases ,greater will be the circuit resistance.
What must have been the velocity of a 250 kg car that has 18000 J of energy?
Answer:
12 m/s
Explanation:
Given,
Kinetic energy ( K.E ) = 18000 J
Mass ( m ) = 250 kg
To find : Velocity ( v )
Formula : -
K.E = mv²/2
v² = 2 K.E / m
= 2 x 18000 / 250
= 2 x 72
= 144
= 12 x 12
v² = 12²
v = 12 m/s
Therefore,
the velocity of the car is 12 m/s

The segment of the motion that net force act on the object causing a positive acceleration is segment 1.
Motion of an objectThe motion of an object occurs when a net force greater than zero acts on the object.
The force on the object is determined from Newton's second law of motion.
