<span>The tire will rotate about 10 million times. An automobile tire is slightly less than 2 and half feet in diameter. It's circumference is that times pi with is a bit over 3. So 2.5 * 3 = 7.5 ft as an estimate for how far the tire rolls per revolution. A mile is a bit over 5000 feet, so call it 700 revolutions per mile. For the 35000 miles, call it 7 times 5000 miles. Now 7 times 7 is a bit under 50, so call 7 * 700 = 5000. And 5000 times 5000 = 25000000. The nearest order of magnitude is 10 million. So as an order of magnitude estimate, a automobile tire will rotate about 10 million times during it's life.</span>

Q7) A box sliding with a velocity of 5 m/s accelerates at 2 m/s^2. How
grigory [225]

Answer:

The box displacement after 6 seconds is 66 meters.

Explanation:

Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object (\Delta s), in meters, can be determined by the following expression:

\Delta s = v_{o}\cdot t+\frac{1}{2}\cdot a\cdot t^{2} (1)

Where:

v_{o} - Initial velocity, in meters per second.

t - Time, in seconds.

a - Acceleration, in meters per square second.

If we know that v_{o} = 5\,\frac{m}{s}, t = 6\,s and a = 2\,\frac{m}{s^{2}}, then the box displacement after 6 seconds is:

\Delta s = 66\,m

The box displacement after 6 seconds is 66 meters.

Blababa [14]

In the increasing size order, they are Universe, Andromeda galaxy, solar system, Arcturus, Sun, Earth.

  • The universe, cosmos contains all things. It has countless billions of galaxies.
  • The Andromeda Galaxy, together with the Triangulum Galaxy and about 30 other smaller galaxies, is the largest galaxy in the Local Group, which also contains the Milky Way.
  • A solar system comprises a star and all its planets, asteroids, comets, and other celestial bodies. It is considerably bigger in the universe, cosmos than a star.
  • Arcturus is a huge red star in the Northern Hemisphere of the Earth's atmosphere. When the sun has evolved into a red giant, it will look like Arcturus. Arcturus has a diameter that is roughly 25 times greater than the sun and earth.
