PLZ HELP The diagram shows the electric field due to point charge Q. The negative charge, A, is within the field.
Charge Q has vectors radially outward starting perpendicular from the surface. The farther you get from the charge, the shorter the vectors. All vectors point towards the charge. A point labeled A is just to the right of the charged object.

Which statements are correct? Check all that apply.

Charge Q is positive.
Charge Q is negative.
The electric field is uniform.
The electric field is nonuniform.
If charge A is negative, it moves away from charge Q.
If charge A is positive, it moves away from charge Q.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
