1 mol KMnO₄ contains 4 mol O, which has a molar mass of about 15.999 g/mol. Then the mass of O in the sample is
(4 mol) (15.999 g/mol) ≈ 63.996 g
Explanation:
Given
perpendicular (p) = 48
base(b) = 14
hypotenuse (h) = x = ?
We know by using Pythagoras theorem
x² = p² + b²
x² = 48² + 14²
x² =2304 + 196
x² = 2500
x = √2500
Therefore x = 50

It’s the magnet cause it is the only one that can pull something in or push away without being to close
Answer:
Look below
Explanation:
If apostolic is for some reason prevented, it can lead to uncontrolled cell division and the subsequent development of a tumor.
A) The x-component of the shot's acceleration while in flight is; aₓ = 0 m/s²
B) The y-component of the shot's acceleration while in flight is;
a_y = -9.8 m/s²
C) The x-component of the shot's velocity while in flight is; vₓ = 7.55 m/s
D) The y-component of the shot's velocity while in flight is;
a_y = 9.32 m/s
<h3>Projectile motion</h3>
A) The x-component of the shot's acceleration while in flight?
aₓ = 0 m/s²
B) Since the object is thrown vertically, it means that it is against gravity and as such acceleration due to gravity will be negative,
Thus, the y-component of the shot's acceleration while in flight is;
a_y = -9.8 m/s²
C) The x-component of the shot's velocity at the beginning of its trajectory is; v_x = v cos θ
v_x = 12 cos 51
v_x = 7.55 m/s
D) The y-component of the shot's velocity at the beginning of its trajectory is; v_y = v sin θ
v_y = 12 sin 51
v_y = 9.32 m/s
