A bag weighing 20 N is pushed horizontally a distance of 35 m across a
topjm [15]

Answer:

350J

Explanation:

Given parameters:

Weight of bag  = 20N

Distance moved horizontally  = 35m

Force applied  = 10N

Unknown:

Work done on the bag  = ?

Solution:

Work done is the force applied to move a body through given distance.

  Work done  = Force applied x distance

So;

 Work done  = 10 x 35  = 350J

Is it possible to accelerate while moving constant speed
marusya05 [52]

Answer:

Explanation:

An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.

If the _____ work on a simple machine equals the output work, the machine is said to be 100% efficient.
omeli [17]
<h3>Answer:</h3>

Input work

<h3>Explanation:</h3>

Concept being tested: Efficiency of machines

Therefore we need to know what is the efficiency of a machine

  • Efficiency of a machine is the ratio of work output of machine to the work input expressed as a percentage.
  • Thus;

Efficiency = (Work output ÷ Work input) × 100%

  • Therefore, if the work input is equal to the work output then the efficiency of the machine will be 100%.
  • Most machines are not 100% efficient due to loss of energy in form of heat due to friction of the moving parts of the machine.
