Velocity ratio is also defined as the ratio of a distance through which any part of a machine moves, to that which the driving part moves during the same time. An object has a mechanical advantage if it exerts a force higher than the velocity ratio.
Answer:
force and mass sorry i dont clear
Explanation:
Answer:
C voltage
Explanation:
Voltage is the change in electric potential so basically current flows from high potential to low potential due to voltage.
Answer:
Answers are in the explanation
Explanation:
a)
vf² = vi² + 2gh
0 = vi² + 2(-9.8)(72)
vi = 37.57 m/s
b)
vf = vi + gt
0 = 37.57 - (9.8)t
t = 3.83 s
3.83 x 2 = 7.67 s
vf = vi + gt
vf = 37.57 - (9.8)(7.67)
vf = -37.60 m/s
c)
Its vertical velocity at the highest point is 0 m/s
Answer:
because dust particles wants to stay in rest but when we hit or beat carpet it comes in motion and due to unbalanced inertia it's fall down..
