Answer 1

We conclude that the quantity of the charge that flows through the wire in 50 s will be 45 C.

Step-by-step explanation:

Given

• Current I = 0.9 A

• Time t = 50 s

To determine

We need to find the quantity of the charge that flows through the wire in 50 s.

Important Tip:

A current of 1 Ampere = 1 Coulomb of charge flowing in 1 second

Using the formula involving charge and current

`I=(Q)/(t)`

where:

• 
  `I` represents the current in amperes (A)

• 
  `Q` represents the charge in coulomb (C)

• 
  `t` represents the time in seconds (s)

now substituting I = 0.9 and t = 50 in the formula

`I=(Q)/(t)`

`0.9\:=\:(Q)/(50)`

switch sides

`(Q)/(50)=0.9`

Multiply both sides by 50

`(50Q)/(50)=0.9\cdot \:50`

Simplify

`Q=45` C

Therefore, we conclude that the quantity of the charge that flows through the wire in 50 s will be 45 C.
