Answer:
False.
Explanation:
We usually define vectors in terms of its magnitude and their orientation. Magnitude and direction does not vary with the change of a coordinate system as they are independent of coordinates and will remain the same. So it does not matter what your choice of a coordinate system is, it will not effect its direction and magnitude. However you can resolve the vector in to its components if you want.
A gas doesn't have a fixed shape because the amount of space between the molecules in gas can change easily. B. the particles are not compressible
<span>
they're both properties of water. both involve the "sticking" property of H2O .</span><span>
cohesion is "sticking" together (water sticking to water) and adhesios is water</span><span>
</span>
"sticking" to something else. They are both important to life processes.
<span>In chemistry, adhesion refers
to the tendency of unlike molecules to bond with one another, while
cohesion refers to the attractive force between molecules of the same
type. Surface tension, which is an essential property of water, illustrates the relationship between adhesion and cohesion.</span>
Answer:
repulsion force es R = 5,224 10⁻³ N
Explanation:
We use Newton's second law to add forces, the elective force is repulsive because the asteroids have the same type of charge and gravitational force is always attractive.
Gravitational force
Fg = G m1 m2 / r²
Fg = 6,673 10⁻¹¹ 5.7 10⁴ 5.5 10⁴/190²
Fg = 5,795 10⁻⁶ N
Electric force
Fe = k q1 q2 / r²
Fe = 8.99 10⁹ 14.0 10⁻⁶ 15.0 10⁻⁶ / 190²
Fe = 5.2296 10⁻³ N
The resulting force is
R = Fe - Fg
R = 5.2296 10⁻³ - 5.795 10⁻⁶= 5229.6 10⁻⁶ - 5,795 10⁻⁶
R = 5,224 10⁻³ N
this is a repulsive force and the asteroids move away from each other
The polarized glasses contain a special filter that blocks the glares and the hazes while driving through the sun or looking at the water, which makes your eyes more comfortable and makes you see better.
Hope this Helps! :)
