Answer:
The coefficient of friction in the hall is 0.038
Explanation:
Given;
mass of the Parker, m = 73.2 kg
applied force on the parker, F = 123 N
frictional force, Fs = 27.4 N
the coefficient of friction in the hall = ?
frictional force is given by;
Fs = μN
Where;
μ is the coefficient of friction
N is normal reaction = mg
Fs = μmg
μ = Fs / mg
μ = (27.4) / (73.2 x 9.8)
μ = 0.038
Therefore, the coefficient of friction in the hall is 0.038
Answer:
The two defining characteristics of a vector are its magnitude and its direction.
Explanation:
Explanation:
the correct answer is Option 5.√½gh.
hope this helps you.
DISTANCE
-length of the path between two points
-doesn't have to be a straight path
-has no direction
DISPLACEMENT
-the length from the starting point to the ending point
-must be a straight path
-must have direction (north, south, east, west, up, down)
EXAMPLE-If you wanted to know the distance from your house to the park, you could say 'three blocks north and then two blocks west' but for displacement, you could just cut through houses and backyards to get to the destination.
Hope that makes some sense :)
I believe it’s; C) points 2 and 4
Explanation: for a current to flow, it needs a closed path :)
