Answer:
d
Explanation:
This is because momentum is defined as p = mv
delta p = Force *time
neither velocity nor time is given so a conclusion cannot be made on which has the greatest momentum change.
The answer is solar flare ; an eruption of high - energy radiation from the sun.
The correct answer is
1
Potassium has 1 valence electron. In fact, it is in the same group of sodium in the periodic table. But sodium has 1 valence electron, since it is in the 11th position, because the first two elements of the periodic table fills the first orbital, while the elements from 3 to 10 fill the second orbital (made of 8 electrons), so the 11th element (sodium) has 1 valence electron.
Answer:
Explanation:
We need to make an sketch of the two forces acting over the point A, and then we analyze the forces in each of the components x and y.
Therefore, finding the resulting force using Pythagoras ' theorem and the angle of the force with respect to the horizontal.
In the attached image we can find the sketch with the equations used to find the resultant force and the angle.
