Kinetic energy than parked
0.078 times the orbital radius r of the earth around our sun is the exoplanet's orbital radius around its sun.
Answer: Option B
<u>Explanation:</u>
Given that planet is revolving around the earth so from the statement of centrifugal force, we know that any

The orbit’s period is given by,

Where,
= Earth’s period
= planet’s period
= sun’s mass
= earth’s radius
Now,

As, planet mass is equal to 0.7 times the sun mass, so

Taking the ratios of both equation, we get,





Given
and

Answer:
Number of slices of pizza is 993.
Explanation:
It is given that, in one slice of "everything" pizza there are 650 Calories. The conversion factor from calories to joules is :
1 calorie = 4.184 joules
650 calories = 2719.6 joules
Total energy in the pizza, E = 2700000 J
Let there are n number of slices of pizza. It is given by :

n = 992.79
or
n = 993
So, there are 993 slices of pizza. Hence, this is the required solution.
B is true, however that is not a way in which conserving and recycling paper helps manage energy sources...
