𝟙.) Use the table to answer the question.
Object Charge (C)
A +1
B +2
C –1
D –2
Assuming other factors are held constant, which two objects will have the strongest attractive force between them?
🅰🅽🆂🆆🅴🆁: Object B and object D
𝟚.) How does the distance between charged objects affect the electric force between them?
🅰🅽🆂🆆🅴🆁: As distance increases, the strength of the force decreases.
𝟛.) Which material would be the best conductor of electricity?
🅰🅽🆂🆆🅴🆁: Copper
𝟜.) Which particles move freely in a conductor?
🅰🅽🆂🆆🅴🆁: Negatively charged electrons
𝟝.) How would increasing the voltage and the resistance affect the electric current in a simple circuit?
🅰🅽🆂🆆🅴🆁: Increasing the voltage would increase the amount of current. Increasing the resistance would decrease the amount of current.
𝟞.) A simple electric circuit has the following properties:
resistance: 12 ohms
voltage: 96 V
Which circuit below has the same current?
🅰🅽🆂🆆🅴🆁: Resistance: 6 ohms Voltage: 48 V
𝟟.) When a hydroelectric dam is operating, falling water moves turbines, which are able to generate an electric current. Which energy transformations are taking place during operation?
🅰🅽🆂🆆🅴🆁: Potential to kinetic to electrical
𝟠.) An electric current moves through a circuit that makes a complete loop. How will the amount of electrical energy change as the current moves through the circuit?
🅰🅽🆂🆆🅴🆁: Electrical energy will decrease if it is converted into other forms, such as heat or mechanical energy.
𝟡.) Which option could be the load of an electric circuit?
🅰🅽🆂🆆🅴🆁: Light bulb
𝟙𝟘.) How does a light switch control a light?
🅰🅽🆂🆆🅴🆁: The switch opens or closes the circuit.
𝟙𝟙.) Use the table of information about three electromagnets to answer the question.
Electromagnet Current Intensity Number of Turns in the Wire
J high 20
K medium 20
L high 45
Which list shows the electromagnets in order from weakest magnetic force to strongest magnetic force?
🅰🅽🆂🆆🅴🆁: K, J, L
𝟙𝟚.) How is an electric field produced?
🅰🅽🆂🆆🅴🆁: When an object has an electric charge

Mommy is right
I'm sorry, I'm not sure what you are referring to. Can you please provide more context or information?
To determine which two objects will have the strongest attractive force between them, we need to consider the charges of the objects. According to the table provided:
Object A has a charge of +1.
Object B has a charge of +2.
Object C has a charge of -1.
Object D has a charge of -2.
In electrostatics, opposite charges attract each other. So, the strongest attractive force will occur between two objects with opposite charges.
Looking at the options:
- Option "object A and object C" has opposite charges of +1 and -1 respectively.
- Option "object A and object B" has the same charges of +1 and +2 respectively, so this is not correct.
- Option "object B and object D" has the same charges of +2 and -2 respectively, so this is not correct.
- Option "object B and object C" has opposite charges of +2 and -1 respectively.
Considering all the options, the correct answer is: object A and object C, as they have opposite charges of +1 and -1 respectively.
