Therefore, our final answer is that our pencil weight 3.5 grams

The heat of fusion must be approx from 0 to infinity
Answer:
5.024 years
Explanation:
T1 = 1 year
r1 = 150 million km
r2 = 440 million km
let the period of asteroid orbit is T2.
Use Kepler's third law
T² ∝ r³
So,
T2 = 5.024 years
Thus, the period of the asteroid's orbit is 5.024 years.
Answer:
This experiment lets you repeat Galileo's experiment in a vacuum. The free fall of a coin and feather are compared, first in a tube full of air and then in a vacuum. With air resistance, the feathers fall more slowly. In a vacuum, the objects fall at the same rate independent of their respective masses.
