Suppose c⃗ =a⃗ +b⃗ where vector a⃗ has components ax = 5, ay = 2 and vector b⃗ has components bx = -3, by = -5. what is the direction of vector c⃗ ?

326,3° or 146,31°

Explanation:

So you know that A=(5,2) and B=(-3,-5)

so C is going to be=(5,2)+(-3,-5)=(2,-3)

The direction of a vector is the measure of the angle it makes with a horizontal line.  One of the following formulas can be used to find the direction of a vector:

tanα=

tanα=---> arctg()=α=326,3° or 146,31°

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
