There is no change in the weight of either
Air has no influence on the weight of an object unless the object is accelerating down through an air column. The air resistance to the free fall of the object may have an influence on its instantaneous weight of the object.
Explanation:
The weight of an object is influenced by the mass of the object and gravity. Gravity also has influence in a vacuum. Therefore the wooden and iron piece will weight the same in a vacuum as in the air.

Answer:
By observing the color of lines in the spectrum.
Explanation:
There are two types of lines in the spectrum explained below:
i) Bright lines: Bright lines occurs on the spectrum when atoms emit photons. These bright lines show the emission line spectrum.
ii) Dark Lines: Dark lines occurs on the spectrum when atoms absorb photons. These black lines show the absorption line spectrum.
Hence, by observing the color of lines it is possible to identify emission line spectrum and absorption line spectrum.
Answer:
there is an mobile an a latter
Based on the weights of the crate on the different planets, the mass of the given planets compared to the earth are as follows:
- Mercury - lower mass than Earth
- Venus - lower mass than Earth
- Mars - lower mass than Earth
- Jupiter - higher mass than Earth
- Saturn - higher mass than Earth
- Uranus - higher mass than Earth
- Neptune - higher mass than Earth
<h3>What does the weight of an object depend on?</h3>
The weight of an object depends on the mass of the object as well as a constant known as acceleration due to gravity, g.
For an object of constant mass, its weight depends only on the acceleration due to gravity on the object.
The higher the mass of an object, the greater will be its value of acceleration due to gravity.
Hence, for planets in which the weight of the object is less than on earth, the planets will have a lower mass than earth. On the other hand, for planets in which the weight of the object is more than on earth, the planets will have a higher mass than earth.

D) strongly acid
<h3>Explanation</h3>
A neutral solution have a pH of 7. All the solutions with a pH less than 7 are acid, and the more they tend to 0, the more they are acid. Viceversa with the solutions with pH greater than 7
