Answer:The percentage of the work input that becomes work output is the efficiency of a machine. Because there is always some friction, the efficiency of any machine is always less than 100 percent.

Answer:
9 N
Explanation: Given that L = side of the cube = 10cm = 0.1m
Mass = Density * Volume
Let’s determine the volume of the cube in m^3.
V = L^3
V = 0.1^3 = 0.001m^3
Mass = 0.001 * 2.053 * 10^4 = 20.53kg
Weight = 20.53 * 9.8 = 201.194
Buoyant force = 201.194 – 192 = 9.194 N
This is approximately 9 N.
We don't know if the road is perfectly straight between the intersections, or if the road bends, curves, or turns between them. So we don't have enough information to calculate the displacement between them.
But we <em>can</em> calculate the <u>distance</u> the car traveled between them.
Distance = (speed) (time)
Distance = (20 m/s) (120 s)
<em>Distance = 2,400 meters</em>

Answer:
t=0.58s
Explanation:
We can consider only the horizontal component since the horizontal component of the velocity is constant (
), and we want to know how much time it takes for the balloon to travel a horizontal distance 
at that speed. The definition of (horizontal) velocity is 
, so we have:
