According to Newton's third law
- Ever action has a equal and opposite reaction.
So
- Hence if applied force is 8000N opposing force is also 8000N
As car is pushed forward so the opposing force is less than 8000N
I think you would be using a topographic Map, So the answer should be A
Because the object is still made of the same material
Density is not affected by the weight and shape of an object its affected by how concentrated the atoms are in a given volume
I think its the car moving to a stop sign
Answer:
1299 N/m²
Explanation:
Applying,
P = ρgh............... Equation 1
Where P = pressure of water at the bottom of the container, ρ = density of water, h = height of water in the container, g = acceleration due to gravity.
but,
V = πr²h............ Equation 2
Where V = volume of water, r = radius of the container
make h the subject of the equation
h = V/πr².................. Equation 3
From the question,
Given: V = 200 liters, = 200000 cm³, r = 70 cm
Constant: π = 22/7
Substitute these values into equation 3
h = 200000/[(22/7)(70²)]
h = 12.99 cm
h = 0.1299 m
Also given
Constant: g = 10 m/s², ρ = 1000 kg/m³
Substitute these values into equation 1
P = 0.1299(10)(1000)
p = 1299 N/m²
