Two resistors of resistance 19 ohm each are connected in series.
In series combination, equivalent resistance = 19+19 = 38 ohm
Potential difference = 10 V
V/I = R
I ( current ) = V/R = 10 V / 38 ohm = 0.26 ampere
Answer:
The two waves will add vectorially to produce a small amplitude wave in a valley phase.
Explanation:
The two waves will add vectorially to produce a small amplitude wave in a valley phase. This is because the amplitudes of the waves are slightly different and in opposite directions. When wave 1 cancels out all of wave 2, the resultant wave would be the slight difference between both waves, and it would be in the direction of wave 1 which is a valley phase.
Answer:
+b±√b² - 4ac /2a
0.6t ± √36-36/2a
Explanation:
Work done = 1/2 mv² where v = (1.2)²
Therefore, 1/2m(1.2)ω mgh
1/2m (1.2)² = 0.4 × m ×10 5
s = 1.44 / 2.4 = 1.44 / 8
S = ut - 1/2gt²
Where u = 1.2
g = 0.9 × 10
Therefore,
1.8 = 1.2v-2t²
2t²c-1.2t+1.8 = 0
t² - 0.6t + 0.9 = 0
0.6t ± √36-36/2a
Solving this further, we make use of the formula
+b±√b² - 4ac /2a
For us to understand the missing item that would complete beta decay reaction, we need to achieve in depth understanding of chemical formulas and nuclear symbols. Next is to have great comprehension of the following points:
<span>1.) Neutron in nucleus breaks down and changes into a proton.
2) Then it emits an electron, as well as an anti-neutrino which go into space.
3) Lastly, atomic number continuously goes UP while mass number remains unchanged.</span>
Answer:
the ratio of protons to neutrons
Explanation:
Nuclear stability is based on the ratio of protons to neutrons. The nuclear space is made up of protons and neutrons that occupies the nucleus of an atom.
For every atomic nucleus, there is a specific neutron/proton ratio which ensures the stability of the nucleus.
For sodium, Na, the neutron/proton ratio for stability is 12/11.
Any nucleus with a neutron/proton combination different from its stability ratio will be unstable.
