Please help me I'm stuck on this question

Option C. 1.8 A

Explanation:

We'll begin by calculating the equivalent resistance of the circuit. This can be obtained as follow:

Resistor 1 (R₁) = 20 Ω

Resistor 2 (R₂) = 30 Ω

Resistor 3 (R₃) = 10 Ω

Equivalent resistance (R) =?

R = R₁ + R₂ + R₃ (series connection)

R = 20 + 30 + 10

R = 60 Ω

Finally, we shall determine the current flowing through the circuit. This can be obtained as shown below:

Voltage (V) = 110 V

Equivalent resistance (R) = 60 Ω

Current (I) =?

V = IR

110 = I × 60

Divide both side by 60

I = 110 / 60

I = 1.8 A

Thus, the current flowing through the circuit is 1.8 A.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures

the ima (higher than 1m) will be greater than the ima with the height of 1m.
