velocity=displacement/time
displacement=∆velocity x ∆time
displacement=4x4

The answer is elliptical orbits. Here is are my reason for thinking it is what I know it is. All planets move in elliptical orbits, with the sun at one focus. This is one of Kepler's laws. The elliptical shape of the orbit is a result of the inverse square force of gravity. The eccentricity of the ellipse is greatly exaggerated here.
Answer;
Row to row
In a periodic table a set of properties repeats from row to row
Explanation;
In a periodic table, a set of properties repeats from row to row. This is called the periodic law. In the periodic table, the rows are called periods and the columns are called groups.
The modern periodic table is organized by increasing atomic number. The atomic mass unit is based on 1/12th the mass of a carbon-12 atom.
The atomic mass of an element is the weighted average of the masses of an element’s isotopes.
Heyyyyyyyyyy how is your day goingggg luvvvv
Answer:
It is virtual and behind the mirror
Explanation:
When an image is produced by a mirror, we have the following situations:
- The image is said to be in front of the mirror if it is on the same side of the object, with respect to the mirror
- The image is said to be behind of the mirror if it is on the opposite side of the object, with respect to the mirror
Moreover:
- The image is said to be real if it is in front of the mirror
- The image is said to be virtual if it is behind the mirror
In this case, the image (located at point I) is on the opposite side of the object (located at point O), so it is virtual and behind the mirror.
