15 lb is nearly 6 kg amd 50 n is nearly 5 kg,so first puppy weighs more
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
The correct answer to fill
in the blank would be:
“a barrier island”
Barrier islands are
coastal landforms and a category of dune system that are remarkably even or
lumpy areas of sand that was formed by wave and tidal actions that are parallel
to the mainland coast. Due to this feature, there are no enough sand blockades
to minimize the destruction by Hurricane Sandy.
That should be the Grasslands ?
Answer:
it may be because of the movement of the atoms. i believe that the heat of the warm water makes it move faster, thus making the object float due to upthrust, or air pressure
