The scientists need to measure for forces are magnitude and direction.
<h3>What is Force?</h3>
The force is defined as the external effort applied in the form of push or pull to cause the acceleration of a body.
Mathematically it is expressed as the product of mass and acceleration of an object.
therefore standard expression for the force as per Newton's second law is given as,
F = ma
Here,
m is the mass of the body.
a is the magnitude of the acceleration of the body.
Also, the force is a vector quantity that has significance for its magnitude as well as the direction.
So scientific analysis regarding the force needs its magnitude along with the direction of application.
Thus,The scientists need to measure for forces are magnitude and direction.

The four scientific principles of sustainability are...
1. Reliance of solar energy
how much of the sun we reuse.
2. Biodiversity
When there is a large verity of species.
3. Nutrient Recycling
When a Population benefit from other populations.
4. Population control
When one type of population of species is to large.
Have a wonderful day

None of the above! You can use the headlights even if the visibility is way under 1000feet. There are many countries especially in Europe where headlights/daylights must be always on with no regard to visibility conditions. In some cities you will be even given a fine for not having the lights on all the time. But rules vary from country to country...
T, because everybody knows that you can make your own goal by yourself, you dont have to depend on someone
