Answer:

Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing. These tools allow for more precise and accurate observations. Scientists also use equipment to measure things like radiation or pH – phenomena not directly observable.

Scott is making a chart to show the difference between chemical reactions and nuclear reactions. Which part of his chart is inco
Nimfa-mama [501]

Answer:

The incorrect part of the chart is;

Line 1

Chemical {} Reaction   {}                                   Nuclear Reaction

Line 1 Happens in the nucleus of atoms   {} Happens between atoms

Explanation:

The given chart can be presented as follows;

  Chemical Reaction {}                               Nuclear Reaction

1. Happens in the nucleus of atoms    {}   Happens Between atoms

2. Forms new compounds {}                     Forms new atoms

3. Involves small amounts of energy {}    Involves large amounts of energy

From the above chart, line 1 is incorrect because a chemical reaction happens between the valence electrons of the reacting atoms while a nuclear reaction is the reaction that takes place between the nucleus of two or more atoms or the nucleus of an atom and a subatomic particle to produce one or more than new nuclide of a new atom with a change in the mass of the nucleus being represented by the large amount of energy in the reaction. Therefore, a nuclear reaction takes place in the nucleus of an atom, forms new atoms and involves large amounts of energy

The correct arrangement is presented as follows;

  Chemical Reaction {}                              Nuclear Reaction

1. Happens Between atoms    {}                Happens in the nucleus of atoms

Discuss the difference between waveform graphs and vibration graphs​
Kitty [74]

Difference exists mainly in the label for x axis.

Explanation:

  • Shapes of waveform and vibration graphs are same.
  • Vibration graphs shows the particle at a single location in the path of the wave when time passes.
  • Waveform graphs shows the particle at multiple locations at a single moment of time.

A piece of wood has a volume of 4.6 cm to the power of 3, and a mass of 3.7 g what is the density of the wood
AysviL [449]

Density is given by:

D = M/V

D = density, M = mass, V = volume

Given values:

M = 3.7g, V = 4.6cm³

Plug in and solve for D:

D = 3.7/4.6

D = 0.80g/cm³
