Answer:
As a result, Sofa's acceleration was 2 m/s² according to Newton's Second Law of motion.
Explanation:
Newton's Second Law, also called the Fundamental Law of Dynamics, indicates that: "The change in motion is directly proportional to the printed motive force and occurs according to a straight line along which that force is printed." This means that the acceleration of a moving object depends on the amount of force applied to it at a given moment, in order to modify its trajectory or speed.
So, Newton's second law states that a body accelerates if a force is applied to it. The acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object:
F = m * a
where "m" is the mass of the object, "a" is the acceleration and "F" is the net force, that is, the vector sum of all the forces acting on the object.
In this case:
Replacing:
300 N = 150 kg*a
Solving;
300 N÷ 150 kg=a
2 m/s²=a
<u><em>As a result, Sofa's acceleration was 2 m/s² according to Newton's Second Law of motion. </em></u>
Answer:
133.33 g/mole
Explanation:
To get the molar mass, you will need to first determine the atoms in the compound.
AlCl₃
We have aluminum (Al) and Chlorine (Cl)
Next step is to determine how many atoms of each element you have in the compound. The subscript will tell you how many. If you see no subscript, that means 1 atom.
Al = 1 atom
Cl = 3 atoms
Then you multiply the number of atoms by the atomic weight to get the molar mass of each element and add them up to get the total molar mass of the compound:
Element # of atoms atomic weight molar mass
Al 1 x 26.98 g/mole = 26.98 g/mole
Cl 3 x 35.45 g/mole = <u>106.35 g/mole</u>
TOTAL = 133.33 g/mole
Answer: Starches, carbon dioxide, and sugar.
Explanation: plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
