A street that is 172 m long is coverd by snow . City workers are useing a snowplow to cleer the street . A tire on the snowplow has turn 43 tines on traveling the lenght .What is the diamater of the tire ?

Answers

Answer:

The diameter of the tire is 1.274 m

Explanation:

Given;

total length of the street, L = 172 m

let the radius of the tire = r

let the diameter of the tire, d = 2r

In every single turn, a tire covers a distance, D = 2πr

for the total 43 times, the distance covered, D = L = 43 x 2πr

L = 43 x 2πr

172 = 86πr

[tex]r = \frac{172}{86 \pi} \\\\r = 0.637 \ m[/tex]

d = 2r = 2 x 0.637

d = 1.274 m

Therefore, the diameter of the tire is 1.274 m

__ is the tradition of a widow killing herself by throwing her body on her husband's burning funeral pyre; it is performed __ today in India.
A. Agni Purana, daily
B. Sati; very rarely
C. Juche; often
D. Shinto; not at all​

Answers

The Sati is an ancient Hindu funeral practice where a widow immolates herself on her husband's funeral pyre. B. Sati; very rarely

The tradition described in the question is known as "Sati."

Sati is an ancient Hindu funeral practice where a widow immolates herself on her husband's funeral pyre.

The term "Sati" is derived from the name of the goddess Sati, who is believed to have self-immolated in a mythological tale.

While Sati was practiced in India in the past, it has been officially banned by the British colonial administration in the early 19th century.

The ban was implemented due to the inherent cruelty and violation of human rights associated with the practice.

Sati had already been in decline prior to the ban, as social reformers within India had been advocating against it.

Today, Sati is considered illegal and a criminal offense in India.

It is also condemned by religious authorities and most members of Indian society.

The Indian government has taken significant measures to enforce the ban and prevent any instances of Sati from occurring.

Laws have been enacted to protect the rights and safety of widows, and there are severe penalties for anyone involved in promoting or participating in Sati.

While it is true that rare instances of Sati may still occur, they are illegal and highly condemned.

The Indian government, along with various organizations and activists, is actively working to prevent and eradicate this practice completely.

It is important to recognize that Sati does not represent the mainstream or contemporary cultural practices in India.
