Which statement is correct? (2 points)
Lemur [1.5K]

Answer:

When a neutral atom looses an electron to another neutral atom, two charged atoms are created.

Explanation:

On the off chance that one of the two unbiased particle looses an electron, it turns out to be emphatically (charge: +1), in light of the fact that the electron conveys a charge of - 1. Thus, the other atom which acknowledges the electron turns out to be adversely charged (charge: - 1). And in the end, we will have two charged atoms.

Choose the sequence of energy forms that best fits each item.
levacccp [35]

Answer:

1. chemical energy --> electrical energy --> light energy

2. Electrical Energy --> Mechanical Energy

3. Electrical Energy --> Heat Energy

4. Chemical Energy --> Thermal Energy  --> Mechanical Energy

5. Nuclear Energy --> Light energy and thermal energy

6. Mechanical Energy --> Electric Energy

7. Chemical Energy --> Electrical Energy --> Sound Energy

8. Mechanical Energy --> Sound Energy

Explanation:

1.<u>FLASHLIGHT</u>:

chemical energy --> electrical energy --> light energy

The chemical energy from the cell batteries is converted to electrical energy, which is used to produce the light energy in form of flashlight.

2.<u>ELECTRIC SAW</u>:

Electrical Energy --> Mechanical Energy

The electrical energy from the socket is converted to the mechanical energy used to run the saw blade.

3.<u>TOASTER</u>:

Electrical Energy --> Heat Energy

The electrical energy from the socket is converted to the heat energy (thermal energy) used in browning the bread.

4.<u>GAS POWERED SCOOTER</u>:

Chemical Energy --> Thermal Energy  --> Mechanical Energy

The chemical energy from fuel, such as petrol is converted to heat (thermal energy) in the engine by the process of combustion. This heat is then used to do work by conversion into mechanical energy, through piston movement, which in turn moves the shaft and the scooter.

5.<u>THE SUN</u>:

Nuclear Energy --> Light energy and thermal energy

The nuclear reactions on Sun provide nuclear energy which is converted into light and thermal energy that reaches us on earth.

6.<u>WIND TURBINE</u>:

Mechanical Energy --> Electric Energy

The mechanical energy is provided by wind when it rotates the blade of turbine. This is then converted to electrical energy b the turbine.

7.<u>IPOD</u>:

Chemical Energy --> Electrical Energy --> Sound Energy

The chemical energy i supplied by the battery of ipod, which is converted to electrical energy and that electrical energy is used to produce sound by ipod.

8.<u>SPEAKER VIBRATES</u>

Mechanical Energy --> Sound Energy

The mechanical energy due to vibration produces sound energy.

Label each statement 1 2 or 3 for the law of motion it illudtrates​
AveGali [126]

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction
