Explanation / Answer

Q-3

1 ft = 0.3048 meters

So

417 ft = 417*0.3048 meters

          = 127.102 meters

1 inch = 0.0254 meters

So

10 inches = 10 * 0.0254 m

                = 0.254 m

So 417ft 10 in = 127.102 meters + 0.254 meters

                     = 127.356 meters

Q-4)

1 Metric Ton = 1000 kg

No. of people would it take to move the Statue of Liberty = 205 metric tons. / 80

                                                                                  = 205 * 1000 / 80

                                                                                  = 2562.5 = 2563

                                                                                 2563 units of people required

Q-5)

Given Data

4.5 million pounds = 4,500,000 lb

Lets Assume a person can pull an average of 110 kg

Solution :-

I assume they're pulling it straight up (in other words, that it's not rolling or sliding along the ground), and that they're doing it on the surface of the earth, where gravity is 9.8 m/s^2.

(It actually doesn't make much sense to refer to people being able to pull mass - we move things by applying a force. On the moon, we can lift more mass than we can on the Earth, because gravity is lower, and the same mass weighs less - but our strength is the same! But that's maybe getting beyond the scope of the problem.)

So, 110 kg/person * 9.8 m/s^2 = 1078 kg*m/s^2, or 1078 N/person (Newtons).

A Newton is the metric unit of force, and there's a relationship between Newtons and pounds, just like there is between meters and inches.

1 Newton is approximately equal to 0.225 lb.

So, 1078 N/person * 0.225 lb/N = 242.34 lb/person.

That means, if you have a bunch of average people pulling, each one will pull with 242.34 lb of force.

Another way too look at it is, if you multiply that by 1 person, that's 242.34 lb/person * 1 person = 242.34 lb.

If the space shuttle is 4,500,000 lb, then it would take 4,500,000 lb / (242.34 lb/person) = 18,569 people

18,569 people units of people required

Q-6)

We have

I fathom = 6 ft
I mile = 5280 ft

Given Data

Distance of Uranus = 1.607 * 10^6 miles

convert to feet:
1.607 * 10^6 mile * 5280 ft/mile

= 8484.96 * 10^6 ft

convert to fathoms:
8484.96 * 10^6 ft * 1fathom / 6feet
     = 1414.16 * 10^6 fathoms = 1.4142*10^9 fathoms
