Which words identify the scientific parts of a wave? check all that apply.

breaker
crest
current
drift
trough

The words that identify the scientific parts of a wave are;

Explanation:

Crest is the highest point of a wave positioned at the peak.The distance between two crests in a wave represents the wavelength of that wave.You can imagine a series of mountains, where the peak points now reprrsent the crest.Trough is the lowest point of a wave positioned at its bottom side.The distance between two trough points respresent the wavelength of the wave.

crest

trough

I hope this helps

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

because if the tool that you are using is not balanced it there would be false mass.
