Answer:
<h2>9000 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 900 × 10
We have the final answer as
<h3>9000 N</h3>
Hope this helps you
Answer:
f = 3 × 10⁶ Hz
Explanation:
Given data:
Wavelength of wave = 1.0 ×10² m
Frequency = ?
Solution:
Formula:
Speed of light = wavelength× frequency
Frequency = speed of light / wavelength
speed of light = 3× 10⁸ m/s
f = 3× 10⁸ m/s / 1.0 ×10² m
f = 3 × 10⁶ s⁻¹
s⁻¹ = Hz
f = 3 × 10⁶ Hz
You have to find the stoichiometric ratio between AlCl₃ and BaCl₂. The common element between them is Cl. So, the ratio of Cl in BaCl₂ to AlCl₃ is 2/3. The molar mass of AlCl₃ is 133.34 g/mol. The solution is as follows:
Mass of AlCl₃ = (6 mol BaCl₂)(2 mol Cl/1 mol BaCl₂)(1 mol AlCl₃/3 mol Cl)(133.34 g/mol) = 533.36 g AlCl₃

Idk if i'm too late but the answer should be A.
