Answer:
1638.225ms-1
Explanation:
Mass of block= 16.1 Kg
Mass of bullet = 0.08Kg
Initial velocity of block= 0ms-1
Initial velocity of bullet= ????
Final velocity of bullet and wood= 8.1 ms-1
From Newton's third law:
Momentum before collision= momentum after collision
MAUA + MAUB= V(MA +MB)
(0.08×UA) + (16.×0)= 8.1(0.08+16.1)
0.08UA= 131.058
UA= 1638.225ms-1
Answer:
Gamma rays occupy the short-wavelength end of the spectrum; they can have wavelengths smaller than the nucleus of an atom. Visible light wavesare one-thousandths the width of human hair--about a million times longer than gamma rays. Radio waves, at the long-wavelength end of the spectrum, can be many meters long.

<span>The atom becomes positively charged.
When you add electrons to a neutral atom, it is no longer a neutral atom, it has a negative change and is an anion. When you take away electrons from a neutral atom, it is no longer a neutral atom- it becomes a positive atom, and is a cation.</span>
