For Art class, Social Studies class, English class, American History class,
or Photography class, Shani has done an incredible amount of work.
She'll tell her parents all about it at dinner, and her arms will really ache
when she gets up tomorrow morning.
But it's a different story in Physics class. In Physics, there is a formal definition
for "work". (That's so it can be measured, and numerically compared to all forms
of energy.)
The scientific definition of work is
(force exerted) times (distance moved) .
With this definition, if the force doesn't move through a distance,
then the work done is zero.
Anything you do without moving, even if it's holding a small car over
your head for an hour while your muscles tremble and sweat pours
down, represents no "work" in the scientific sense.
since airplane is thrown towards west with speed 6 m/s
while air is blowing with speed 8 m/s towards north
so here the net speed of air plane will be the resultant of airplane speed and wind speed always
SO here we can say it would be a combination of vector along west with must be of length 6 m/s and other vector is towards north with is of length 8 m/s
so correct answer must be 1st option
Answer:
The graph of a quadratic function is a parabola whose axis of symmetry is parallel to the y -axis. The coefficients a,b, and c in the equation y=ax2+bx+c y = a x 2 + b x + c control various facets of what the parabola looks like when graphed.
