Write each force in component form:
<em>v </em>₁ : 50 N due east → (50 N) <em>i</em>
<em>v</em> ₂ : 80 N at N 45° E → (80 N) (cos(45°) <em>i</em> + sin(45°) <em>j</em> ) ≈ (56.5 N) (<em>i</em> + <em>j</em> )
The resultant force is the sum of these two vectors:
<em>r</em> = <em>v </em>₁ + <em>v</em> ₂ ≈ (106.5 N) <em>i</em> + (56.5 N) <em>j</em>
Its magnitude is
|| <em>r</em> || = √[(106.5 N)² + (56.5 N)²] ≈ 121 N
and has direction <em>θ</em> such that
tan(<em>θ</em>) = (56.5 N) / (106.5 N) → <em>θ</em> ≈ 28.0°
i.e. a direction of about E 28.0° N. (Just to clear up any confusion, I mean 28.0° north of east, or 28.0° relative to the positive <em>x</em>-axis.)

Answer:
Gravity is the force of attraction between two objects; it is dependent upon the mass of the objects and the distance between the objects.
Explanation:
Gravity is defined as the force of attraction between two objects. It depends on the masses of objects and the distance between them. The gravitational force between two bodies is given by the universal law of gravitation. According to this law, the force of gravity is :
Where
G is the universal gravitational constant
m₁ and m₂ are masses of two bodies
d is the distance between two bodies
Hence, the correct statement that describes gravity is (b)
Answer:
Interface
Explanation:
This is a classic example of Interface technology.
An interface allows different software packages to communicate without re-entering data.
Here in this case also systems are able to communicate with one another without duplicating data entry. For example, practice management software and another for their electronic health record.
