Hello there.
<span>
At ground level g is 9.8m/s^2. Suppose the earth started to increase its angular velocity. How long would a day be when people on the equator were just 'thrown off'? Why is the expression 'thrown off' a bad one ?
</span>
People would not be thrown off.

Let s = rate of rotation 
<span>Let r = radius of earth = 6,400km </span>
<span>Then solving (s^2) r = g will give the desired rate, from which length of day is inferred. </span>
<span>People would not be thrown off. They would simply move eastward in a straight line while the curved surface of earth fell away from beneath them.</span>

Why does a box on the seat of a car slide around on the c one the car speeds up slows down or turns a corner?
Feliz [49]
Because the box keeps going straight at the same speed, while the seat under it speeds up, slows down, or changes direction.

Why are ionic solids poor conductors of electricity? The lattice is brittle. The ions are neutral. The ions are of equal but opp
sveta [45]

The ions are in fixed positions.

Explanation:

Ionic solids are poor conductors of electricity because their ions are fixed in position. Their ions are not free to move about. They are fixed in crystal lattices.

  • For the conduction of electricity, compounds must possess free mobile electrons and moving ions in solution.
  • Ionic compounds are formed by the electrostatic attraction between a metallic and non-metallic ion.
  • They actually contain ions but their ions are locked up.
  • They are not free to move about.
  • Electrical conduction involves ion mobility.
  • In molten and aqueous forms, they are able to conduct electricity because their ions are then mobile.

Two air craft P and Q are flying at the same speed 300m/s. The direction along which P is flying is at right angles to the direc
Lerok [7]

Answer:

424.26 m/s

Explanation:

Given that Two air craft P and Q are flying at the same speed 300m/s. The direction along which P is flying is at right angles to the direction along which Q is flying. Find the magnitude of velocity of the air craft P relative to air craft Q

The relative speed will be calculated by using pythagorean theorem

Relative speed = sqrt(300^2 + 300^2)

Relative speed = sqrt( 180000 )

Relative speed = 424.26 m/s

Therefore, the magnitude of velocity of the air craft P relative to air craft Q is 424.26 m/s
