<h2>Answer
</h2>
4.6 m/s in the same direction as 5.8 m/s velocity.
<h2>Explanation </h2>
Velocity is a vector quantity. It has both magnitude and direction.
Taking the 5.8 m/s moving to the right as positive, then the 1.2 m/s moving to the left will be negative.
∴ 5.8 + -1.2 = 5.8 - 1.2
= 4.6 m/s.
Since the answer is positive, it has the same direction 5.8 m/s velocity.
The resultant velocity vector is 4.6 m/s to the right.
Answer:
the advantages of the periodic table are as follows;
Explanation:
- the periodic table is easy to understand and and elements are positioned according to their configurations.
- the lanthanide series as well as the actinide series are seperately placed
- the elements in the table are placed according to their respective atomic numbers thus reduces the complexity of the periodic table.
Answer:
Total Force that the air inside the house exerts upward on the ceiling is 5.25 × 10⁶ lb
Explanation:
Force = Atmospheric Pressure × Floor Area
Where; Standard Atmospheric Pressure = 2100 lb/ft²
Floor Area = 2500 ft²
Substitute the data
∴ Total Force = 2100 lb/ft² × 2500 ft²
Total Force = 5.25 × 10⁶ lb
