You measure my life in hours
I serve you by expiring
I vanish faster when I am thin
and slower when I am thick
The wind is my energy
What am I?

When it is alive we sing, when it is dead we clap our hands. What is it?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

I am an eight letter word and I am a computer terminology.
The second, third and fourth letters make an animal.
The fourth, fifth, sixth, seventh and eighth letters make a weapon.
The first, second, third and fourth letters can be taken as an outcome of any exam.
The fifth, sixth, seventh and eighth letter combine to form a high end typing software.

Can you tell who am I ?

When you say goodbye, I am what you need to tie.
I come as a couple and go wherever you run.
Who am I?

Pronounced as 1 letter, And written with 3, 2 letters there are, and 2 only in me. I’m double, I’m single, I’m black blue and grey, I’m read from both ends, and the same either way. What am I?

Until it is measured, not known. Yet how you miss it when it has gone. What is it?

Two in a corner, one in a room, zero in a house, but one in a shelter. What am I?

What is full of holes but still holds water?

I come in different shapes and sizes.
Parts of me are curved, other parts are straight.
You can put me anywhere you like,
but there is only one right place for me.
What am I?
