To find the order of magnitude of the number of breaths a person takes during an average span of 70 years, we will follow these steps: ### Step 1: Calculate the total time in minutes over 70 years. 1. **Convert years to days**: \[ 70 \text{ years} \times 365 \text{ days/year} = 25,550 \text{ days} \] ...

Let a star be much brighter than our sun but its mass is same as that of sun If our earth has average lift span of man as 70 years In the earth like planet of this star system having double the distance from our star find the average lift span of a man on this planet in terms of our year .

In an imaginary planetary system, the central star has the same mass as our sun, but is much brighter so that only a planet twice the distance between the earth and the sun can support life. Assuming biological evolution ( including aging process etc.) on that is similar to ours, what would be the average life span of a 'human' on that planet in terms of its natural year? The average life span of a human on the earth may be taken to be 70 years.

An amusement park ride consist of a large verticle cylinder that spins about its axis first fast enough that any person inside is held up againest the wall when the is mu_(s) and the radius of the cylider is R a. Shown that maximum period of revolation neccessary to keep the person from falling is T = (4 pi^(2) mu_(s) R //g)^(1//2) b. Obtain a numerical value for T taking R = 4.00m and mu_(s) = 0.400 . How many revolations per minute does the cylinder make? c. If the rate of revolation of the cylinder is make to be some what larger what happens to the magnitude of each one of the forces acting on the person ? What happens to the motion of the person ? d. If instead the cylinder rate revolution is made to be somewhat smaller what happens to the magnitude and what happens to the motion of the person ?
