Answer:

Explanation:
The buoyant force F is equal to the weight of the displaced fluid. The weight of the displaced fluid is  , where
, where  is the mass of the displaced fluid. The mass of the displaced fluid is
 is the mass of the displaced fluid. The mass of the displaced fluid is  , where
, where  is the density of the fluid and
 is the density of the fluid and  is the displaced volume, which is equal to the submerged volume of the cilinder
 is the displaced volume, which is equal to the submerged volume of the cilinder  .
.
Putting all together we have:

Answer:
A) 35 ft
B) 5 ft
C) Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick
Explanation:
A) Total distance covered by the dog = 20 + 15
                                   = 35 ft
B) Since the other distance covered by the dog before chewing the stick, after the retrieval, was in an opposite direction to the initial direction, then;
total displacement of the dog = 20 - 15
                                   = 5 ft
C) Net displacement = distance covered by the dog to retrieve the stick + distance covered before the dog starts chewing the stick
But, displacement involves a specified direction. The distance covered before the dog starts chewing the stick was in an opposite direction to the initial direction.
Thus,
Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick
 
        
             
        
        
        
Answer:
R = 2Ω
Explanation:
Potential difference (V) = current (I) * Resistance (R)
V = IR
I = 2.0A
V = 10v
R = ?
V = IR
R = V / I
R = 10 / 2
R = 2Ω
The resistance across the wire is 2Ω
 
        
                    
             
        
        
        
Answer:Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). ... You probably have an intuitive feeling for density in the materials you use often. For example, sponges are low in density; they have a low mass per unit volume.
