Answer:
Force = 125 [N]
Explanation:
In the attached image we can see a sketch of the lever system.
And if we make a sum of moments at the point O equal to zero (0).
In the equation showed in the image, we can determinate the force that we need
Answer:
1) H. magnitude, 2) D. coordinates, 3) G. distance.
Explanation:
1) A vector has, by definition, both <em>magnitude</em> and direction. (Reason: Scalars have only magnitude)
2) Once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as <em>coordinates</em>. (Reason: Coordinates are ordered pairs)
3) Speed differs from velocity in the same way that <em>distance</em> differs from displacement. (Reason: The distance is the magnitude of displacement)
Answer:
<h3>The answer is 0.47 kg</h3>
Explanation:
The mass of the object given it's momentum and velocity can be found by using the formula
![m = \frac{p}{v} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7Bp%7D%7Bv%7D%20%20%5C%5C%20)
where
p is the momentum
v is the velocity
We have
![m = \frac{7.1}{15} \\ = 0.4733333...](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B7.1%7D%7B15%7D%20%20%5C%5C%20%20%3D%200.4733333...)
We have the final answer as
<h3>0.47 kg</h3>

Answer:
Dryer sheets stop static cling by absorbing static electricity formed by different fabrics during your dryer cycle. The fabric softeners that coat dryer sheets are positively charged ions to balance the electrons and ions that cause static cling, leaving you with soft clothes without the static.
