The second time can someone me force vectors can be added together in any order. it does not matter which vector you draw first, the resultant will be the same, both in length and direction. practice finding resultant vectors by completing this assignment.

you will need a ruler and a protractor. calculate the resultant force vector for each of the following sets of two force vectors. you will need the protractor to make sure you are redrawing each force vector in the right direction using the correct angles. the ruler is used to redraw the force vectors with the correct magnitude. after you sketch the resultant, measure the length and the direction of it. provide the magnitude and direction, including the units, for your answers. the horizontal dotted lines are there simply to you measure the angles with the protractor. graph paper would with this assignment.

vector examples

example a
in example a the first vector is 27° with a force of 23 n. the second vector us 75° with a force of 30 n. use 10 n = 1 cm as your scale. what is the resulting vector?
example b
in example b the first vector is 224° with a force of 27 n. the second vector is 123°, with a force of 32 n. what is the resulting vector?
example c
in example c the first vector is 80° with a force of 16 n. the second vector is 144° with a force of 48 n. what is the force and degrees of the resulting vector?

answer:

dont know

explanation:

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
