Answer:
  c = 5 m
Explanation:
this exercise you want to divide the rectangular room into two triangular rooms
                  
the area of triangles is
            A = ½ base height
            A = ½ 4 3
           A = 6 m²
the length of the curtain can be found using the Pythagorean theorem
            c² = b² + a²
            c = √ (4² + 3²)
            c = 5 m
this is the length of the curtain
 
        
             
        
        
        
The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.
        
             
        
        
        
Answer:
0.16 m
Explanation:
A rectangular gasoline tank can hold 50.0 kg of gasoline when full, and the density of gasoline is 6.8 × 10² kg/m³. We can find the volume occupied by the gasoline (volume of the tank).
50.0 kg × (1 m³/6.8 × 10² kg) = 0.074 m³
The volume of the rectangular tank is:
volume = width × length × depth
depth = volume / width × length
depth = 0.074 m³ / 0.500 m × 0.900 m
depth = 0.16 m
