Answer: The correct option is "a tree trunk".

Explanation:

Transparent is a material which allows the light to pass through it.

For example, glass.

An opaque is a material which does not allow light to pass through it.

For example, wood.

Translucent is a material which allows light partially to pass through it.

For example, butter paper.

In the given options, a pair of eyeglasses, a clear water bottle, a car windshield are transparent materials. But a tree trunk is an opaque as it does not light to pass through it.

Therefore, a tree trunk is least likely allow light to pass through it.

Ratling [72]

The net torque exerted by the children on the branch of the tree is 1382 N-m.

The torque exert by the kids is calculated as

T= 45.6*9.8*1.28*cos27.5°+36*9.8*(2.25-1.28)cos27.5°

T=1382 N-m

Hence, The net torque exerted by the children on the branch of the tree is 1382 N-m.

The sun’s___and the planet’s___keeps planets moving is___orbits.

Sauron [17]

The sun’s gravitational attraction and the planet’s inertia keeps planets moving is circular orbits.

Explanation:

The planets in the Solar System move around the Sun in a circular orbit. This motion can be explained as a combination of two effects:

1) The gravitational attraction of the Sun. The Sun exerts a force of gravitational attraction on every planet. This force is directed towards the Sun, and its magnitude is

$F=G\frac{Mm}{r^2}$

where

G is the gravitational constant

M is the mass of the Sun

m is the mass of the planet

r is the distance between the Sun and the planet

This force acts as centripetal force, continuously "pulling" the planet towards the centre of its circular orbit.

2) The inertia of the planet. In fact, according to Newton's first law, an object in motion at constant velocity will continue moving at its velocity, unless acted upon an external unbalanced force. Therefore, the planet tends to continue its motion in a straight line (tangential to the circular orbit), however it turns in a circle due to the presence of the gravitational attraction of the Sun.
