If u= and v=<3cos45degree,3sin45degree> find the direction of u+v. Put in degrees and round to the nearest tenth.

54.0°

Step-by-step explanation:

We have that:

u=<cos 30°, 4sin30°>

This implies that:

u=<½√3, 2>

Also, v=<3cos 45°, 3sin 45°>

v=<3√2/2, 3√2/2>

u+v=<2.99,4.12)

The direction of u+v, is the angle, it makes with the positive x-axis.

This is given by;

To the nearest tenth, the direction is 54.0°

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
