1. No - energy cannot be created or destroyed.
2.Since the answer to 1 is no, the answer to number 2 is no.
3.It's relative to something, i.e. the absense of something. So it would have to be the absense of space and time, the absense of existence itself.
As far as we know, we live in a...
one parent is 50%, hence you inherent 25% indian from that parent.
The other parent is eithet 1.56% or 3.12% so you inherit 0.78% or 1.56% respectively.
For a total of 25.78% or 26.56% either of which ,depending on rounding, could be said to be 26%
Consider that no two sounds are actually the exact same- so every time you hit the plate: from a physics point of view; it will produce a different sound although you as a person may not be able to distinguish the difference.
What constitutes a certain sound? What determines pitch when hearing...
Have you tried drawing the diagram, something like this:
Where would the image have to be to be bigger than the object?
Which side is known as the real side, which side is known as the virtual side and why?
If 15% is deflected each time, then sirius's intensity, which let's say is 1 becomes 0.614 since (0.85)^3=0.614
Then, log(1/0.614)*2.5=0.5295
0.5295 is hence the difference between the apparnt magnitudes of the star after it has passed through the three windows. -1.5+0.5295=-0.9704
There's...
That's still rather vague. This has been answered a few times on the stack-exchange, i'll link you the links see if they help.

If it's to do with the UK as said above, it depends on your exam board. Do all the exam past papers

and make sure you know everything in the textbook. You can also look at the exam specification to find...
Consider throwing a ball. If you throw the ball, disregarding air resistance, it will not slow down in the direction you throw it in- Newtons first law.
Yet, gravity will pull it down to the Earth. so in the direction you threw the ball in, it will not slow down- it will just speed up towards...
I got you :D. Energy isn't real as such, that's why you're getting intuitively confused. The real phenomena which we experience would be velocity. That's how we percieve the world, through velocity and mass. Everything can come down to velocity and mass.
The rest is just things we believe in...
