Answer:
1700 Joules
Explanation:
Work=force x distance
Force = 170 kg
Distance= 10 Meters
170 x 10 = 1700 Joules of work
 
        
             
        
        
        
Hold on and let's discuss this realistically.
Because of gravity, there are two forces between the Earth and me. One draws me toward the Earth. The strength of that force is what I call my "weight". The other force draws the Earth toward me, and has the same strength.
The strength of these forces depends on the masses of the Earth and me. If the strength just tripled, that means that at least one of us just picked up a lot more mass. If the Earth suddenly became three times as massive, then the weight of everything and everybody on it would suddenly triple, and I'm pretty sure it would be the end of all of us before too long.
If it was only MY mass that suddenly tripled, that would mean that I had gone tearing through my house and the neighbour's house, eating everything in sight including the 2 couches, 3 dogs, and 6 TVs. Naturally, just as you would expect, my weight changed from 207 to 621, and my skin is stretched really tight.
ooohhh
        
             
        
        
        
Answer:
The necessary separation between  the two parallel plates is 0.104 mm
Explanation:
Given;
length of each side of the square plate, L = 6.5 cm = 0.065 m
charge on each plate, Q = 12.5 nC
potential difference across the plates, V = 34.8 V
Potential difference across parallel plates is given as;

Where;
d is the separation or distance between the two parallel plates;

Therefore, the necessary separation between  the two parallel plates is 0.104 mm
 
        
             
        
        
        
Answer
given,
given,
small cube side = 10 cm
larger cube side = 12 cm
density of steel = 7 g/cm³
density of aluminium = 2.7 g/cm³
density of the water (ρ₁)= 1 g/cm³
Cube A and B made of steel 
buoyant force of Cube A
  B₁ = ρ₁ V g = 1 x 10 x 10 x 10 x g=  1000 g
for cube B
  B₂ = ρ₁ V g = 1 x 12 x 12 x 12 x g=  1728 g
buoyant force of Cube C
  B₃ = ρ₁ V g = 1 x 10 x 10 x 10 x g=  1000 g
for cube D
  B₄ = ρ₁ V g = 1 x 12 x 12 x 12 x g=  1728 g
buoyant force acting on the cube depends on the density of the fluid
hence,
  B₂ = B₄  > B₁ = B₃
