Answer:
work done is the product of force and distance moved in the direction of a force
Answer:
Explanation:
ohn Snow inquired about the disease outbreak with the local residents. He found a convincing similarity that the affected people drank water from a particular well. He came to a conclusion that it is spreading through water. Whereas Miasma theory suggested that cholera spreads through air because of the pollutants present. John Snow's argument was that if cholera spreads through air, it would have spread faster than the current affected rate.
According to his assumptions, the well was closed and clean water was supplied and the cholera rate went down in the town.
The weight of object with a mass of 8 kg is 78.4 N.
The weight of object with a mass of 0.04 kg is 0.392 N.
The weight of object with a mass of 760 mg is 7.45 N.
<h3>What is weight?</h3>
The weight of an object is the force acting on the object due to gravity.
Weight, W = mg
where;
- m is the mass of the object
- g is acceleration due to gravity, 9.8 m/s²
<h3>Weight of object with a mass of 8 kg</h3>
W = mg
W = 8 kg x 9.8 m/s²
W = 78.4 N
<h3>Weight of object with a mass of 0.04 kg</h3>
W = mg
W = 0.04 kg x 9.8 m/s²
W = 0.392 N
<h3>Weight of object with a mass of 760 mg</h3>
W = mg
W = 0.76 kg x 9.8 m/s²
W = 7.45 N
Thus, the weight of object with a mass of 8 kg is 78.4 N.
The weight of object with a mass of 0.04 kg is 0.392 N.
The weight of object with a mass of 760 mg is 7.45 N.

Answer:
The gauge pressure is 
Explanation:
From the question we are told that
The height of the water contained is 
The height of liquid in the cylinder is 
At the bottom of the cylinder the gauge pressure is mathematically represented as
Where 
is the pressure of water which is mathematically represented as
Now 
is the density of water with a constant values of 
substituting values
While 
is the pressure of oil which is mathematically represented as
Where 
is the density of oil with a constant value
substituting values
Therefore
