Bruce collects the data on four electric circuits listed in the table.
circuit-voltage-resistance
w-18-38
x-24-34
y-34-70
z-12-18
bruce must report any circuits that deliver more than 4.0 c of charge in 8.0 s.

which lists every circuit that bruce must include in his report?

x and z
x and y
w and y
w and z

Answer : X and Z

Explanation :

For w :

Voltage,

resistance,

so,

So charge,

For x :

Voltage,

resistance,

so,

So charge,

For y :

Voltage,

resistance,

so,

So charge,

For z :

Voltage,

resistance,

so,

So charge,

So, the circuits X and Z delivers 5.64 C and 5.28 C of charge.

Hence, Bruce must include X and Z in his report.
