Answer:

0.2 A

Explanation:

Current: This is the rate of flow of charge in a circuit. The S.I unit of charge is Ampere (A).

Note: When resistors are connected in parallel, the total current is equal to the sum of the individual current in each resistor.

It = I1 + I2 + I3......................... Equation 1

Where,

It = Total current, I1 = current in the first resistor, I2 = current in the second resistor, I3 = current in the third resistor.

Given: It = 0.71 A, I1 = 0.27 A, I2 = 0.24 A.

Substitute into equation 1

0.71 = 0.27+0.24+I3

0.71 = 0.51+I3

I3 = 0.2 A.

Hence the current through the third resistor = 0.2 A

True. Though typically crack deals take place in a car, or in an alley. The middle of a long block is kind of exposed. It could happen anywhere in Chicago though.

Determine the density of a rectangular piece of concrete that measures 3.7 cm by 2.1 cm by 5.8 cm and has a mass of 43.8 grams.
Novay_Z [31]
It is customary to work in SI units.

Calculate the volume of the concrete.
V = 3.7*2.1*5.8 cm³ = 45.066 cm³ = 45.066 x 10 ⁻⁶ m³

The mass is  43.8 g = 43.8 x 10⁻³ kg

The density is mass/volume.
Density = (43.8 x 10⁻³ kg)/(45.066 x 10⁻⁶ m³) = 971.9 kg/m³

Answer: 971.9 kg/m³

Distinguish between a converging lens and a diverging lens.
andriy [413]

Answer:A converging lens is thickest in the middle and causes parallel light rays to converge through the focal point on the opposite side of the lens. A diverging lens is thinner in the middle and causes parallel light rays to diverge away from the focal point on the same side of the lens.

Energy is the ability to do work. True or false
Blababa [14]
Work can be defined as the energy transferred from a body to its sorroundings, the energy spent to move a body, or the energy you need to alter a charged particle, so no energy, no work; thus, the statement is true.
