Answer:
time rising = 34 / 9.8 = 3.47 sec
total time in air = 2 * 3.47 sec = 6.94 sec
(time rising must equal time falling)
R = 17 m/s * 6.94 s = 118 m
Can also use range formula
R = v^2 sin (2 theta) / g
tan theta = 34 / 17 = 2
theta = 63.4 deg
2 theta = 126.9 deg
sin 126.9 = .8
v^2 = 17^2 + 34^2 = 1445 m^2/s^2
R = 1445 * .8 / 9.8 = 118 m agreeing with answer found above
Surveys are considered the most reliable way to gather data
P₄ + 3O₂ ⟶ 2P₂O₃
Explanation:
A balanced equation is any equation that complies with the law of conservation of matter and mass.
The law of conservation of matter states that "in a chemical reaction, matter is neither created nor destroyed but simply rearranges. ".
This suggests that the total number of atoms on both reactant and product sides must be the same in a balanced chemical equation. Also, the same atoms are found on both sides of a chemical equation with no additional or external species.
Now let us check if the equation is conserved:
P₄ + 3O₂ ⟶ 2P₂O₃
Atoms reactant product
P 4 4
O 6 6
We see that we have equal number of atoms on both sides. The equation is balanced.

Explanation:
Convergent boundaries (where plates collide) and divergent boundaries (where plates split apart).
Answer:
Time period, T = 403.78 years
Explanation:
It is given that,
Orbital distance, 
Mass of the Earth, 
Mass of the planet, 
Let T is the orbital period of this planet. The Kepler's third law of motion gives the relation between the orbital period and the orbital distance.
or
T = 403.78 years
So, the orbital period of this planet is 404 years. Hence, this is the required solution.
