Answer:
25000 mm: because 25 m × 1000 mm /1 m = 25000 mm
Explanation:
We can convert 25 m to millimetre (mm) by doing the following:
Recall:
1 m = 1000 mm
Therefore,
25 m = 25 m × 1000 mm /1 m = 25000 mm
25 m = 25000 mm
Thus, 25 m is equivalent to 25000 mm
Hello!
Answer:
Explanation:
→ The force applied to an object is equal to:
Where:
- a is the acceleration
- F is the force
- m is the mass
→ So, the acceleration of the car is equal to:
Conclusion:
The acceleration of the car is 1.30m/s².
Explanation:
acceleration is directly proportional to the force and inversely proportional to the mass of the object
a=f/m
=1700/1300
The radius of a positive ion always less than the radius of its neutral atom because the nucleus pulls the remaining electrons in closer.
Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus.
Only the most prevalent kind of hydrogen is neutron-free. The smallest component of ordinary stuff that makes up a chemical element is an atom.
Quarks and electrons are the two categories of fundamental particles that make up an atom. An atom's nucleus is surrounded by an area of electrons. The electrical charge of every electron is negative one.
Protons and neutrons, which together make up an atom's nucleus, are made of quarks.
Thus, option A is correct.

Molecular clocks
Molecular clocks use the relationship between the DNA of several groups of organisms to evaluate how long ago they diverged evolutionarily from one another. Therefore, option (4) is correct.
The molecular clock can be described as a figurative term for a technique that utilizes the mutation rate of biomolecules to determine the time when two or more life forms diverged. The biomolecular data used are usually nucleotide sequences for DNA, RNA, or amino acid sequences for proteins.
The benchmarks for calculating the mutation rate are often fossil or archaeological dates. The molecular clock is commonly used in molecular evolution to estimate times of speciation or radiation.
The molecular clock can only give one time period as it cannot assign concrete dates. For viral phylogenetics and ancient DNA studies, the areas of evolutionary biology, the intermediate samples can be utilized to more precisely calibrate the molecular clock.
