Answer:
the 2kg ball
Explanation:
there is less mass to move so the 2kg ball will move faster. the kinetic energy of the 5kg ball will move slower due to the fact that it needs more energy to move if it has more mass.
<span>a) All the 26m should be used to bent into a square to maximize the total area (= 42.25 m2)
b) 1.4136m should be bent into a square and the rest (= 24.586m) should be bent into an equilateral triangle to minimize the total area (= 29.0835m2)</span>
<u>We are given:</u>
2 Vectors A and B
A = î - 5j
B = 2î - 10j
<u>Proving that the given vectors are Parallel:</u>
We can rewrite the Vector B as: B = 2(î - 5j)
Since A = î - 5j
Vector B can be written as:
B = 2(A vector)
this means that the magnitude of Vector B is twice of vector A but their direction is the same
Since the 2 vectors are moving in the same direction, they are parallel
Answer:
c
Explanation:
electronic balance must always be at zero to prevent errors in measured value
Answer:
2 N
Explanation:
The equation of the forces along the direction perpendicular to the plane is
where
R is the reaction force
is the component of the weight perpendicular to the plane, with
m = 5.0 kg being the mass of the plane
acceleration of gravity
Solving for R,
(1)
The frictional force is given by
where
being the coefficient of friction
Using (1), we find
