Identify 5 things that would happen if there is not electricity.
Brilliant_brown [7]

If the power is out long enough even the city folks will run out of water. Many homes are all electric, so as soon at the lights are out they have no heat, no hot water and they can't cook. ... If the power is out, gas stations can't pump gas. Once generators run out of gas, those people will be in the dark too.

A solid object has a mass of 1.62 lb and a volume of 190 mL.
Pachacha [2.7K]

The density of a solid object that has a mass of 1.62 lb and a volume of 190 mL is 3.87g/mL.

<h3>How to calculate density?</h3>

Density is the measure of the mass of matter contained by a unit volume. It can be calculated by dividing the mass of the substance by its volume.

According to this question, a solid object is said to have a mass of 1.62 lb and a volume of 190 mL.

1 pound = 453.592 grams

1.62 Ibs is equivalent to 734.82 grams

Density of the solid object = 734.82 grams ÷ 190 mL

Density = 3.87g/mL

Therefore, the density of a solid object that has a mass of 1.62 lb and a volume of 190 mL is 3.87g/mL.

Container A holds 717 mL of ideal gas at 2.50 bar . Container B holds 179 mL of ideal gas at 4.30 bar . If the gases are allowed
Nesterboy [21]

Answer:

Pressure gas A

using boyles law

p1}V_{1} = P_{2}V2

V2 = 717ml + 179 ml

     = 896ml

∴ P_{2} = 2.50 × 717ml/896ml

       = 2.0 bar

Pressure B

P2 = 4.30 bar× 179ml/896ml

     = 0.859bar

ptotal = P_{A}+P_{B}

          = 2.0 bar + 0.859 bar

           = 2.859 bar

           

Explanation: Using Daltons law of partial pressure,the pressure is independently of each other when the gas is exerted.where we can use daltons law to find the pressure of each gas separately when it expands into the total volume in two containers.

Are the charges in the finger attracted or repelled by the charges in the doorknob? How can you tell?
ludmilkaskok [199]

The charges in the finger are attracted by the charges in the doorknob because charges that are the same repel each other. Charges that are different attract each other. The electric field is pulled toward the other charged object if their charges are different.
