Question: 18 kilogram Mass Block rest on level surface if the coefficient of static friction between the Block and the surface is 0.6 what horizontal force is required to just move the blcok ( take gravity as 10m/s2
)
Answer:
108 N
Explanation:
From the question,
Applying
F' = mgμ................ Equation 1
Where F' = Frictional force = horizontal force required to just move the block, m = mass of the block, g = acceleration due to gravity, μ = coefficient of static friction.
From the question,
Given: m = 18 kg, μ = 0.6, g = 10 m/s²
Substitute these values into equation 1
F' = 18×0.6×10
F' = 108 N

Explanation:
it is almost zero .this is because the distance and the electrostatic force are inversely proportional
The formation of the outer planets are affected by their
distance from the sun with having them to maintain the lighter elements that
they are composed of such as the hydrogen and helium, having them far away will
also make their planet more cooler as the sun is distant from them.
When looking for distance you multiply speed by time
So 15 x 2 = 30
30 is the distance between his house and school
