Answer:Explanation:
A microscopic hair examination can also determine if a hair was forcibly removed, artificially treated or diseased. A comparison microscope can be used to compare a questioned hair to a known hair sample in order to determine if the hairs are similar and if they could have come from a common source.
Answer:
A is the correct option.
Explanation:
Physics primer is a set of mathematics topics that are relevant to introductory physics courses. The idea behind the physics primer is to provide the students a strong base of mathematics concept that can be helpful for them in the future courses of physics. It should be taken before the introductory lessons of physics. It will help out students in solving those physics problems that involves mathematics. Physics primer is usually comprised of tutorials, answers of specific questions and videos.

Answer:
The acceleration of the wallet is
Explanation:
Given that,
Radius of purse r= 2.30 m
Radius of wallet r'= 3.45 m
Acceleration of the purse
We need to calculate the acceleration of the wallet
Using formula of acceleration
Both the purse and wallet have same angular velocity
Hence, The acceleration of the wallet is
The correct answer is :
According to classical electrodynamics, light energy is a wave that is absorbed by atoms in a manner similar to how an object absorbs radiant heat. So, the atoms of a metal would absorb more energy the brighter the light was. It would be feasible for an electron in a metal to break free from its atoms if it received enough energy from the incoming wave. The more energy absorbed, the more energetic the metal's released electrons would be. Additionally, no electrons could conceivably be ejected until each atom had enough light energy. Light intensity was far more important than light frequency.
In many respects, the photo-electric effect contradicted this strategy:
- If the light was below a specific frequency, no matter how bright it was, no electrons were released. Increased light intensity increased the number of electrons that were released, but not their energy, if the light was above this frequency.
- Regardless of how weak the light was, electrons were nearly immediately emitted from the metal.
- Even though the intensity of the light was reduced, an increase in its frequency led to more energising electrons leaving the metal.
