Answer:
Diameter of the piston would be 0.71 m (71.1 cm)
Explanation:
From the principle of pressure;
= 
Let
= 2903.57 lb,
= 24.41 lbs,
= 3.26 cm = 0.0326 m.
= 
=
x
= 0.00334
So that:
= 
= 
= 0.3973
= 0.4 
The radius of the piston can be determined by:
= 
0.3973 =
x 
=
= 0.1264
r = 
= 0.3555
r = 0.36 m
Diameter of the piston = 2 x r
= 2 x 0.3555
= 0.711
Diameter of the piston would be 0.71 m (71.1 cm).
The answer is:
3) a hockey puck moving at constant velocity across ice.
The explanation:
when the Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.
- A force which is not opposed by a force of equal magnitude and acting in the exact opposite direction hence leading to the motion of the object is called an unbalanced force.
- The forces which speed up slow down the objects or makes them change their direction are called Unbalanced forces.
and the phase which satisfy this definition is (3)
Net force can be defined as the sum of force acting on an object in all the directions
.i.e Net force= F acting on a body at upward direction+ F at downward direction+ F at leftward direction+ F at rightward direction.
e.g if a body is at rest the sum of forces acting on body in all direction is zero
but if a body is moving its mean body is facing an unbalanced net force.
Answer:
Data from a cross-sectional study or survey might need to incorporate weights or design effects in the analysis.The analysis plan should specify which variables are most
