The two forces are 12N and 10N (option B)
<h3>What is the net force?</h3>
The net force is the force that has the same effect in magnitude and direction as the two forces acting together.
This problem can be solved using a right angled triangle;
Let the forces be P and Q
sin 40 = P/16
P= 16 sin 40
P = 10 N
Cos 40 = Q/16
Q = 16 cos 40
Q = 12 N

Answer:
<em>You can increase the ideal mechanical advantage of an inclined plane by decreasing the angle of the inclined plane</em>
Explanation:
<u>Mechanical Advantage Of An Inclined Plane
</u>
Since the sloping surface of the inclined plane is always greater than its height, the ideal mechanical advantage of an inclined plane is always greater than 1. To compute the ideal mechanical advantage for an inclined plane, we divide the length of the incline by the height of the incline. For example, An inclined plane that is 10 meters long and 5 meters high has an ideal mechanical advantage of 2.
If we look at the inclined plane as a triangle formed with the height and the horizontal surface, the length L of the inclined plane is the hypotenuse of such triangle and h is the opposite leg of the angle formed with the floor. Since:
The mechanical advantage is
As decreases, its sine also decreases and the mechanical advantage (its reciprocal) will increase. Thus the answer is
<u>You can increase the ideal mechanical advantage of an inclined plane by decreasing the angle of the inclined plane</u>
Answer:
Ionic Compound
Explanation:
To identify the type of chemical bond in a molecule, look at the atoms that make up the compound. If there are two nonmetals, it is a covalent bond. If the two atoms are metals, it is a metallic bond. If one atom is a metal and the other is a nonmetal, it is an ionic bond. Ionic compounds are also known as salts. You can identify KBr as an ionic compound because potassium is a metal and a salt.
