Answer:
A: Object A will move in the up direction. But not object B
Explanation:
It will move in the up direction because object A has an unbalanced force. For the up direction there, it is 6 newtons and for the bottom direction, it is 2 newtons. For the right and left direction, both of them are 3 newtons. So object A will move in the up direction because it has the most newtons(which is 6).
For Object B, it is unbalanced too. But object B will move to the right because it is 2 newtons there and there is one newton on the left. Furthermore, the up and down directions are 3 newtons. So they are balanced and will cancel out. Therefore, object A will move in the right direction because it has the most newtons(which is 3).
So the final answer is object A. Hope it helped!
The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL). Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.
Explanation;
Writing scientific notation :
- Move the decimal to the left side until single digit of number remains before the decimal.
- Then we will count the number of times we moved the decimal. Write this number as the exponential power of number '10'.
- For Example:
Radius of the sun = 696,000.0 kilometer
Radius of the sun can also be written as = 
Size of bacterial cell = 
millimeter
Size of bacterial cell can also be written as = 
Answer:
The elements in Group 2 (beryllium, magnesium, calcium, strontium, barium, and radium) are called the alkaline earth metals (see Figure below). These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is ns
