Answer:
Development of the gene chromosome theory
Explanation:
The speed of a beam of light will appear the same to all observers.
<h3>Speed of light:</h3>
The exact distance that light travels in a vacuum in a second is 299,792,458 meters (983,571,056 feet). This is roughly 186,282 miles per second, or "c," the symbol for light speed in mathematics.
According to Einstein's theory of special relativity, an object (such as a single photon of light) cannot appear to move faster than the speed of light. This physical rule is not broken by Nemiroff's experiment since the laser pointer emits a stream of photons rather than a single photon.
Nothing can move faster than light in a vacuum, according to one of physics' most revered rules. However, in a recent experiment, this speed restriction was broken when a laser pulse traveled at more than 300 times the speed of light.

The density of an object is the mass of the object divided by its volume.
Remember that mass of an object is the amount of matter that the object contains. The unit for mas in the standard international unit system is the kilogram (kg), which is 1000 grams; the unit of mass in the US is the pound (lb), which is 453.592 grams.
The volume of an object is the amount of space that the object occupies. The unit for volume in the standard international unit system are the cubic meter (
) and the liter (L); 1 cubic meter equals 1000 liters.
The density of an object is the quantity of mass of the object per unit of its volume. The unit for mas in the standard international unit system is the kilogram per cubic meter (
).
Now, lets create our hypothesis:
If the mass and the volume of and object are known, then its density can be calculated dividing the object's mass by its volume.
We can conclude that the density of an object can be obtained by dividing its mass by its volume.
Electrical voltage is the potential energy of an electrical supply stored in the form of an electrical charge. From the equation I = V/R, the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance.Therefore, the voltage of the current increases as it passes through a resistor.

Answer:</h3>
AgCl + NaNO₃
<h3>
Explanation:</h3>
- The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
- In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
- In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
- Therefore, the complete reaction is given by;
AgNO3 + NaCl → AgCl + NaNO₃
- But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.
