<u>Answer:</u> the absolute age of the rocks.

<u>Reasoning:</u> The relative age of a rock is not an exact age. rather it's the comparison of one rock or fossil to another to find which one is older or younger.

What is the net ionic equation for a reaction between HCl and NaOH
kodGreya [7K]

Answer:

What is the net ionic equation for a reaction between HCl and NaOH?

Explanation:

A salt is a neutral ionic compound. Let's see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl

Hope that helped.

Please help this is so hard 1: Why is the sky blue?
kolezko [41]

Answer:

1. As white light passes through our atmosphere, tiny air molecules cause it to 'scatter'. Therefore, blue light is scattered more than red light and the sky appears blue during the day.

2. We can see the moon during the day for the same reason we see the moon at night. The surface of the moon is reflecting the sun's light into our eyes. When we see the moon during the day it's because the moon is in the right spot in the sky and it's reflecting enough light to be as bright, or brighter, than the sky.

3. At eight pounds per gallon, that's another 38,593,169,564 pounds of water in the air. Add it all up, and the total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds!

4. 5.972 × 10^24 kg

5. Four forces keep an airplane in the sky. They are lift, weight, thrust and drag. Lift pushes the airplane up.

6. Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.

7. Rainbows are formed when sunlight is scattered from raindrops into the eyes of an observer. The lower the sun in the sky the more of an arc of a rainbow the viewer will see. Rain, fog or some other source of water droplets must be in front of the viewer.

8. Birds can sit on power lines and not get electric shocks because the electricity is always looking for a way to get to the ground. The birds are not touching the ground or anything in contact with the ground, so the electricity will stay in the power line.

Need help please it must be right thank u
vova2212 [387]

Answer:

13. c) Net

14. a) Gravity

15. d) Watt

16. b) the speed will suddenly decrease.

Explanation:

13. The <u>net </u> force is combination of all individual forces.

14. When we sit on the chair , then <u>gravitational force</u> acts on our body due to our mass.

F = mg

here, F = force due to gravity , g = acceleration due to gravity  and m= mass of the body

15.Power : It is the force acting per unit area .It is discovered by James Watt

Power =\frac{force}{area}

Power =\frac{N}{m^{2}}

Its unit is Nm^{-2} .In honor of the Scientist , its unit is Watt.

Watt = Nm^{-2}

16. When the parachute first opens , the <u>speed of the skydiver suddenly decreases</u> because of the resistance offered by the air particles.(For more details look at the figure attached)

17. Transfer of momentum from one object to other is t<u>he law of conservation of momentum</u><u> </u>(NOT ENERGY).So the answer is<u> </u><u>False</u>

<u> Law of Conservation of Momentum : </u> Total momentum of a system is conserved if no external force attack on it. Momentum can neither be created nor destroyed but transferred from one form to other.
