The Laws of Badminton
A match consists of the best of 3 games of 21 points.
Every time there is a serve – there is a point scored.
The side winning a rally adds a point to its score.
At 20 all, the side which gains a 2 point lead first, wins that game.

Answer:
In the second case there's no way to know what depth the bullet will penetrate into the block.
Explanation:
Since the block is on a <em>frictionless </em>surface, when hitted by the bullet, this last one could barely penetrate the surface of the block and, both, start moving as one (<em>perfectly inellastic collition</em>) since here, there's no vise to hold the block into place.
I’m not sure what your question is but I hope I can be of help. Series would split voltage and have same current all through, whereas parallel would have the same voltage all throughout but would have different amperes(currents)
Answer:Zero
Explanation:
Given
mass of ball 
If the ball is thrown upward then at maximum point velocity of ball is zero because ball is no longer able to move upward
Momentum(P) of a particle is given by



Therefore at the highest point momentum is zero .
'Doing work' is a way of transferring energy from one object to another, energy is transferred when a force moves through a distance.
If i explain with formula
Work done (J) = Energy transferred (J)
So more energy, more work done bc u transferred more energy to move the object and doing the work. and if you only use a little of energy, the work done also only a little.
