<h3>What is matter?</h3>
The matter has volume and space occupied.
When conceivable the researcher endeavors to test his speculations via painstakingly planned and controlled tests that will yield quantitative instead of subjective outcomes.

Answer:c
Explanation:
In Physics we follow the sign convention i.e. work done by the system is considered as positive i.e. work is being done by system on the surrounding and vice-versa.
For heat :Heat added to the system is considered as Positive while heat loss to surrounding is considered as negative.
thus doing work on the surrounding(work done by system) w=+
Losing heat to the surrounding q=-
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that the gravitational force is given as
so we will have to find the ratio of force on two planets due to star
so here we have
Part b)
Orbital speed is given as
so the ratio of two orbital speed is given as
Part c)
Time period is given as
so the ratio of two time period is given as
B. Half a centimeter per year
