Answer: The correct answer is Option D.

Explanation:

Venus is the second planet of our solar system and is similar in size as compared to Earth. It's atmosphere is mainly composed of carbon dioxide with minor amounts of nitrogen. This planet have a fixed orbital time around the sun which is 225 days.

Moon is the natural satellite of Earth and is smaller than Earth. It is composed of mainly oxygen, silicon, magnesium, iron, calcium, and aluminum. The orbital period of moon around Sun is 29.5 days.

Halley's Comet is a comet which is very small as compared to Earth and is composed of water, carbon monoxide, carbon dioxide and other ices. It appears in every 75-76 years.

Hence, all of the above have highly predictable orbits around the Sun. Therefore, the correct answer is Option D.

Answer: F = 1235 N

Explanation: Newton's Second Law of Motion describes the effect of mass and net force upon acceleration: $F_{net}=m.a$

Acceleration is the change of velocity in a period of time: $a=\frac{\Delta v}{\Delta t}$

Velocity of the car is in km/h. Transforming it in m/s:

$v=\frac{47.10^{3}}{36.10^{2}}$

v = 13 m/s

At the moment the car decelerates, acceleration is

$a=\frac{13}{0.2}$

a = 65 m/s²

Then, force will be

$F_{net}=19(65)$

$F_{net}$ = 1235 N

The horizontal net force the straps of the restraint chair exerted on the child to hold her is 1235 newtons.

andrew11 [14]

Answer:

a shiny smooth leaf

Explanation:

A shiny smooth leaf will cause specular reflection. Other choices will cause diffused reflection from the surface.

A specular reflection is similar to how a mirror or smooth surface reflects. The incident light is given off as a single ordered reflection from the surface of a body.

For this to occur, the surface incident must be smooth and without rough patterns on it.

A path way with rough rocks, small patch of soil and rough logs will give off diffused reflection
