A scoop of ice cream is placed on top of a warm piece of pie in a bowl.
Lisa [10]

Answer:

b. The overall amount of energy in the bowl will neither increase nor decrease.

c. The ice cream will increase in energy.

Explanation:

b. The total amount of energy in the container will not increase or decrease. Since the energy is transferred from one element to another, the energy that dissipates is negligible.

In this case the energy of the pie is transferred to the ice cream, melting it.

c. The ice cream will increase in energy. As the heat is transferred from the pie to the ice cream. the movement between the particles of the ice cream increases, increasing its kinetic energy

is Earth an open system or closed system? Explain your answer and provide at least one example that occurred during the Precambr
Ivan

Answer:

The Earth is essentially a closed system; it obtains lots of energy from the Sun but the exchange of matter with the outside is almost zero. Isolated systems can exchange neither energy nor matter with an outside system.

The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period. It is now known, however, that life on Earth began by the early Archean and that fossilized organisms became more and more abundant throughout Precambrian time.

9.40_Q1) Which particle moves through a metal wire as electricity?
bija089 [108]

Answer No 1:

The correct option is Electrons.

Electrons are the negatively charged particles of an atom. They revolve around the nucleus of an atom. In circuits, electricity is carried by the electrons which move through a wire. Hence, option C is the correct option.

Other options like option A are not correct because protons are the positively charged particles of an atom. They are present in the nucleus of an atom and hence, do not generate an electric current.

Answer No 2:

Electrons move through the circuit from the negative power terminal to the positive power terminal.

Electrons make up the negative charged particles of an atom. They are involved in the conduction of electricity in circuits. In a circuit, the current flows from a negatively powered terminal to a positively charged terminal. This is known as the electron flow. Hence, option A is correct.

Answer No 3:

The correct option is B) Current

The movement or flow of electrons or electric charge is termed as electric current.  Whenever a circuit is completed, current is generated.

Other options like option C, resistance are not correct because resistance is the force which opposes current flow.

Answer No 4:

The correct option is A) Voltage

Voltage can be described as the force which causes electricity to flow in a circuit. Hence, option A is correct.

Other options like option C are jot correct because resistance is the force which opposes the flow of current.

Answer No 5:

The correct option is C) resistance

Resistance can be described as the force which opposes the flow of current. Resistance can be measured in ohms. It can be described as the difficulty which electrons have in moving through a circuit.

Other option like option A is not correct because voltage is the force through which current is generated.

Answer No 6:

The correct option is C amps

The S.I unit through which current is measured is called amperes. The symbol for amperes is A.  Hence, option C is the correct option.

Other options like ohms are not correct because ohms is the S.i unit for resistance.

Answer No 7:

The correct option is A) volts

The S.I unit for voltage is volts. Voltage can be described as the potential difference which is present in a circuit. Hence, option A is correct.

Other options are not correct because amp is the unit of electric current and ohms is the unit for resistance.

Answer no 8:

The correct option is C) ohms

In physics, resistance can be described as the force which opposes the motion of electrons or electrical current. The S.I unit for resistance is ohms. Hence, option C is correct.

Other options like option A is not correct because volts is the S.I unit of velocity. Option B is not correct because amps is the unit for electric current.    

Answer No 9:

The correct option is C) The voltage is decreased because of the electrical resistance.

According to ohm's law electric current is directly proportional to electric current and inversely proportional to electric resistance.

So, when the resistance increases, the voltage decreases.

Why would a third-degree burn be less painful than a first- or second-degree burn involving the same body area?
Irina18 [472]
A third-degree burn would be less painful than a first- or second-degree burn involving the same body area because of the destruction of underlying pain receptors.
Nerve endings are destroyed in third-degree burns, which means that a person can no longer feel pain in that particular spot on the body. Third-degree burns are the most severe ones and cannot be treated easily - usually skin grafting or synthetic skin has to be used to replace the burnt skin.
