Answer:
<u> a = V final 2___v initial2</u>
28
Explanation:
By definition for contant acceleration <u>a = V final ___v initial</u>
t
Furthermore the average speed is <u>V abg = v initial +v final</u>
2
Combine these relationships to eliminate t. 8 = Vabg t.
An 'alpha particle' is the same thing as the nucleus of a helium atom ...
a little bundle made of 2 protons and 2 neutrons.
A 'beta' particle is an electron.
The mass of an alpha particle is more than 7,000 times the mass of
an electron, so it certainly takes more energy to get it moving.
Answer:
1. a) Draw a line towards the right side from the engine
b) This force pushes the boat forward and helps it accelerate further
2. a) Fixed volume for both solid and liquid
Compressible for only solid
Fixed shape is also for only Solid
b) The answer is 'c'
c) Solids, because they have their particles closely packed therefore they can be compressed (not so sure bout this answer)
