Answer:
because the muscles press together and prevent the joint from bending any further
Answer:
Staying the same unless, another force acts upon it
Explanation:
An object will stay still or keep moving at the same pace and in a straight line until acted upon by an external force that is unbalanced.
Conductivity would be the property.
Answer:
The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.Jan 4, 2016
Explanation:
Momentum is the product of mass x velocity.
p = mv
Where: p = momentum
m = mass
v = velocity
Now you can answer your question by finding the momentum of each:
p = mv
p(w) = 12 x 5 = 60
p(x) = 15 x 8 = 120
p(y) = 18 x 2 = 36
p(z) = 28 x 10 = 280
With that you can now arrange them in ascending order (least to greatest):
Y < W < X < Z
Your answer is D.
