Answer:
A) a low specific heat.
Explanation:
As we know that heat given to the sand will increase it temperature
so we can say
here we will have
so now we will have
more change in temperature due to heat given to the sand will show that it must have low specific heat capacity as it inversely depends on the specific heat capacity of the sand
so correct answer will be
A) a low specific heat.
Answer:
<em>1.49 x </em><em></em>
<em></em>
Explanation:
Kepler's third law states that <em>The square of the orbital period of a planet is directly proportional to the cube of its orbit.</em>
Mathematically, this can be stated as
∝
<em>to remove the proportionality sign we introduce a constant</em>
= k
k =
Where T is the orbital period,
and R is the orbit around the sun.
For mars,
T = 687 days
R = 2.279 x
for mars, constant k will be
k = = 3.987 x
For Earth, orbital period T is 365 days, therefore
= 3.987 x
x
= 3.34 x
R =<em> 1.49 x </em><em></em>
