In 5 seconds, no. Of waves formed = 10

So, in 1 second, no. Of waves formed = {(10/5)×1} = 2.

So, frequency = 2 Hertz.

Now, Time period

= 1/Frequency

= (1/2) seconds

= 0.5 seconds (Ans.)

When the distance between hearing the main sound and the reflecting surface is multiplies of 17 metres (twice or three times ) , the ECHO is heard in the form of the last TWO or three phrases of the whole PRODUCED sound .

Your ANSWER............

The RBCs ( Red Blood CELLS ) CONTAINS hemoglobin ..that helps to carry oxygen throughout the BODY .
....
while WBC ( white blood cells ) ...are the blood cells that fight against DISEASES

Positive and NEGATIVE signs in blood means whether or not the blood contains the rhesus antigen. Rh negative means the antigen is not present and it is safe to DONATE that blood to other NEGATIVES and to positives because the LACK of the antigen will not cause an immunity REACTION.

I THINK C is RIGHT ANS

O

The 'O' blood type is also commonly known as the "Universal blood type" or the "universal donor," because it contains neither A nor B antigens on the red blood cells. However, there are both A and B antibodies in the blood PLASMA. As a result, this type of blood can be used as an infusion to give to individuals with any blood type. Nonetheless, due to the presence of antibodies in the blood plasma, the term "universal blood type" is now somewhat contested. Blood type-related complications in blood transfusions may still occur if there is an issue with the 'O' type blood's antibodies. Given the patterns of genetic inheritance that determine blood type, 'O' type blood is relatively uncommon, compared with A or B type blood. 'O'-type blood may be further divided into Rh+ and Rh-, also known as O+ and O-. This distinction refers to the presence or absence of Rh proteins on the red blood cells.

A

The 'A' blood type contains 'A' type agglutinogens, a type of antigen. These antigens are present in the red blood cells of the 'A'-type blood. Individuals with the 'A' blood type have the 'B'-type antibody in their blood plasma. In addition, the red blood cells of 'A'-type blood may contain Rh proteins on the CELL surface. If this Rh protein is present, the blood is categorized as 'A+'. If it is lacking, the blood is 'A-'. With regard to blood transfusions, individuals with 'A' blood type may donate their blood to individuals with 'A' or 'AB' blood types. Patients with Rh+ blood may receive either Rh+ or Rh- blood, but not vice-versa. (If you have Rh- blood, you can only receive a transfusion of Rh- blood.)

B

'B' type blood is characterized by the presence of 'B'-type antigens in the red blood cells and by 'A'-type antibodies in the plasma. As in the case of 'A' or 'O'-type blood, an individual with a 'B' blood type may be Rh+ or Rh-, depending on whether there are Rh proteins on the red blood cells. Individuals with 'B' blood type may donate blood for use by patients with either 'B' or 'O' blood types

AB

The 'AB' blood type, also known as the "universal receiver" blood type, contains both the A and B antigens on the red blood cells, but contains neither A or B antibodies in the plasma. As a result, individuals with the 'AB' blood type may receive transfusions of any kind of blood. However, they can only donate their blood for use by other individuals of the 'AB' blood type. The 'AB' blood type is produced when the alleles, or genetic indicators, of the mother and father are each 'A' and 'B'. Instead of one type dominating the other, and causing the child to be either 'A' or 'B' type, they are both present, to produce 'AB'-type blood. Despite the common use of the term "universal receiver" for AB type blood, the name may be somewhat deceiving. In addition to the A and B antigens that determine a person's blood type by the ABO system, human blood actually contains hundreds of antigens. In most cases, the presence of these other antigens is QUITE uniform throughout the human population. However, in some unusual cases, an individual may be lacking a particular antigen. In these RARE cases, even an individual with an 'AB' blood type may not be able to receive a transfusion of 'AB' blood. As with 'A', 'B' or 'O' blood types, the 'AB' blood type may be either Rh+ or Rh-.

The velocity of sound in DRY air is APPROXIMATELY 343 m/s at a TEMPERATURE of 25 °C. Therefore, the reflecting object must be more than 1.72m from the sound source for echo to be perceived by a PERSON located at the source. When a sound produces an echo in two seconds, the reflecting object is 343m away.

Characteristics of Magnets

The basic characteristics of magnets
are known by any child who has come across a fridge magnet. Magnets snap to objects made out of iron and they either snap to each other or repel. The feeling of the attraction or repel is easy to describe and detect but what is it that creates this behavior? Read on and learn more about the characteristics of magnets and how they manifest themselves in our daily lives.

Two Magnets Interact
If you take two magnets and try to push them together they will either attract or repel. There is a magnetic force between the magnets that can even be felt by your hand. The reason for this behavior is that each magnet has a NORTH and a south pole. When a north pole of one magnet is subjected to a north pole of another magnet the two magnets will naturally repel each other. We learn from this that magnets have the characteristic of opposites that attract and likes that repel. These forces that we see in magnets actually govern most of our reality and this is why we can’t just put a hand through a chair or other material. The repulsive forces that we can see in magnets are there in miniature to keep matters together and solid.

Magnets Have Memory
You can make a simple test with an LCD calculator to see how magnets have memory. Take a permanent neodymium magnet and place it next to the screen of your calculator. You should first have printed a number there. Now, remove the magnet and return the calculator to zero. When you bring the magnet back the same NUMBERS as before will appear again because it was memorized by the magnet. This characteristic of magnets is used in credit cards where the magnetic stripe of the card holds the sensitive INFORMATION of our bank details.

Magnetic Fields
Magnets create magnetic fields that are both protective and stimulating. These magnetic fields can be used for many things and one very popular area of use is magnetic therapy. Magnetic therapy lets the magnetic fields of magnets interact with the blood of the human body. By stimulating the blood circulation the person being treated experiences pain relief and cure of many different ailments. This is also what makes magnetic jewelry an option for better health and well being.

Split a Magnet in Two
Magnets will always have two poles and even if you split a magnet in two you can’t GET rid of this characteristic. The smaller piece will have two poles and this will continue no matter how many splits you make. There are magnets where the poles are set to the same side but these still include two poles. For magnetic therapy and healing purposes the permanent magnets with two OPPOSITE poles are to recommend since they are the most effective.

Yeah but not a very big fan.
Answer--- The Sentinelese, also known as the Sentineliand the North Sentinel Islanders, are an indigenous people who inhabit North Sentinel Island, located in the Bay of Bengal in India.As North Sentinel Island is PART of the Andaman ISLANDS, the Sentinelese are considered to be one of the Andamanese peoples. They are designated as a Scheduled Tribe.An uncontacted people, the group, estimated to be composed of anywhere from 40 to 500 individuals, is BELIEVED to have lived on North Sentinel Island for as long as 55,000 years and speaks the Sentinelese language, a language isolate not RELATED to the native languages found on the surrounding islands.[6][7][8] Indian authorities have put in PLACE laws that prohibit any individual being closer than 3 miles (4.8 km) to the island, for both the safety of outsiders, as the Sentinelese are known to be hostile, and the Sentinelese themselves. Being an isolated group, they likely do not possess the genetic immunity to survive exposure to common viruses, such as influenza and measles.[6][9]

Unlike other ethnic groups found in the Andamanese Islands, who were more welcoming to outsiders and now interact with them somewhat regularly, the Sentinelese appear to have consistently refused any interaction with the outside world.
