Answer:
The surface must be a good absorber of light. Spectra of the planets proved that methane in the atmospheres of these planets is what absorbs red light.
Explanation:
An intensive property will not change if you took a piece ( like color or temperature )
<span>An extensive property will change ( like weight or volume) </span>
<span>1) wall: hard ( intensive); yellow (intensive) </span>
<span>2) ice cube: cold( intensive) ; large( extensive) </span>
<span>3) sofa: brown (intensive); long ( extensive) </span>
<span>4) dog: black ( intensive); heavy ( extensive) </span>
<span>5) stove: hot ( intensive); white (intensive) </span>
Explanation:
hmm by the increasing the size of wheel and decreasing axle
We know that tangential acceleration is related with radius and angular acceleration according the following equation:
at = r * aa
where at is tangential acceleration (in m/s2), r is radius (in m) aa is angular acceleration (in rad/s2)
So the radius is r = d/2 = 1.2/2 = 0.6 m
Then at = 0.6 * 5 = 3 m/s2
Tangential acceleration of a point on the flywheel rim is 3 m/s2
