The minimum speed required for a satellite in order to break free permanently from the planet and the radius of the synchronous orbit of a satellite are 7.3 Km/s and 3.1 × 10⁴ km respectively.

To find the answer, we need to know about the escape velocity and time period of revolving satellite.

<h3>What's the expression of escape velocity of a satellite?</h3>
  • Mathematically, escape velocity= √(2GM/R)
  • G = gravitational constant, M = mass of planet, R= radius of the planet
  • Here, M = 4.74×10²⁴kg, R = 5870 km
  • Escape velocity=  √(6.67×10^(-11)×4.74×10²⁴/5.870×10⁶)

          = 7.3 Km/s

<h3>What's the expression of time period of a circularly orbiting satellite?</h3>
  • T= {2π×r^(3/2)}/√(GM)
  • r= (T/2π)⅔× (GM)^(1/3)
  • r is the radius of the orbit
<h3>What's the radius of the circular orbit, if the time period of the satellite is 16.6 hours?</h3>
  • T = 16.6 hours = 16.6×3600 second = 59760s
  • r = (59760/2π)^⅔× (6.67×10^(-11)×4.74×10²⁴)^(1/3)

        = 3.1 × 10⁴ km

Thus, we can conclude that the escape velocity and the radius of the synchronous orbit of a satellite are 7.3 Km/s and 3.1 × 10⁴ km respectively.

A large truck is crossing a bridge 1 mile long. The bridge can only hold 14000 lbs, which is the exact weight of the truck. The
klasskru [66]
Depends on the weight of the bird.
1) Half a mile is about 800m.
2) 14000 lbs = about 6 tones, same like couple 4WD
3) Fuel consumption is about 20L per 100km or 0.2l each 1km or 0.16L within 800m
4) density of fuel is about 70% of density of water so .... weight of 1.6L of fuel burned would be about 1.6*0.7=1.1 kg

So if birds mass would be below 1 kg - the bridge will not collapse. But if it would be a pelican with the mass of 9kg - it would be a drama :)

A woman climbs up a ladder in 1.37 s at 2.20 m/s. How tall is the ladder?
ArbitrLikvidat [17]

Answer:

The ladder is 3.014 m tall.

Explanation:

To solve this problem, we must use the following formula:

v = x/t

where v represents the woman’s velocity, x represents the distance she climbed (the height of the ladder), and t represents the time it took her to move this distance

If we plug in the values we are given for the problem, we get:

v = x/t

2.20 = x/1.37

To solve this equation for x (the height of the ladder), we must multiply both sides by 1.37. If we do this, we get:

x = (2.20 * 1.37)

x = 3.014 m

Therefore, the ladder is 3.014 m tall.

Hope this helps!
