Answer:
See the answers below.
Explanation:
The magnitude can be easily found by means of the Pythagorean theorem.
We know that the coordinates in x and in y are negative, therefore the vector should be located in the fourth quadrant, see attached image.
And the angle with respect to the horizontal can be determined by means of the tangent of the angle.
These are 40 degrees below the X-positive horizontal axis.
Answer:
See the answer below
Explanation:
T<em>he aspect of the event that relates to matter is </em><em>the materials and different shapes of the balls</em><em> while the aspect that relates to energy is t</em><em>he heights reached by the balls as they bounce off the same floor.</em>
Matter is generally defined as any substance that has weight and is able to occupy space. <u>Hence, the balls being made up of different materials and shapes means that they are made up of matter. </u>
Energy, however, is generally defined as the capacity to do work. The more the energy of a system, the more the work that can be done by the system. <u>The height reached by the balls is thus an indication of the amount of energy possessed by the balls.</u>

Incomplete question as the angle between the force is not given I assumed angle of 55°.The complete question is here
Two forces, a vertical force of 22 lb and another of 16 lb, act on the same object. The angle between these forces is 55°. Find the magnitude and direction angle from the positive x-axis of the resultant force that acts on the object. (Round to one decimal places.)
Answer:
Resultant Force=33.8 lb
Angle=67.2°
Explanation:
Given data
Fa=22 lb
Fb=16 lb
Θ=55⁰
To find
(i) Resultant Force F
(ii)Angle α
Solution
First we need to represent the forces in vector form
Total Force
The Resultant Force is given as
For(ii) angle
We can find the angle bu using tanα=y/x
So
