Answer:
1.6621 x 10^22 atoms are in the bracelet.
Explanation:
Boom logic...
The equation is an oxidation half-reaction, because the Mg is <em>losing electron</em>s to
form Mg²⁺.
<em>L</em>oss of <em>E</em>lectrons is <em>O</em>xidation and
<em>O</em>xidation <em>I</em>s <em>L</em>oss of electrons.
Answer:
In order to calculate the work that the spike did, you have to respect the following equation:
WORK = FORCE X DISPLACEMENT X COS (0)
Explanation:
Work is measured in joules, and is the amount of energy a body needs to make a certain force over a certain distance.
In the case of this bird we would be calculating with the equation written up in the previous item the work that said animal would do to grind a seed.
Protons / Neutrons is your answer
Answer:
wavelength = 0.56 × 10⁻² m
Explanation:
Given data:
Frequency of radiation = 5.4 × 10¹⁰ Hz
Wavelength = ?
Solution:
Formula:
speed of light = wavelength × frequency
wavelength = speed of light / frequency
wavelength = 3 × 10⁸ m/s / 5.4 × 10¹⁰ Hz ( Hz= 1/s)
wavelength = 0.56 × 10⁻² m
