Answer:
The expression is Vmem = ΔV - I*Rax
Explanation:
According to the picture, if switch S is closed, the Cmem will be short. If Vcap = 0, the current flows through the capacitor only (not through Rmem), thus Vmem = 0 after closing S.
When C is fully charged, then we have:
Vmem = ΔV - I*Rax
<h2>
Velocity of puck and the octopus is 10.59 m/s.</h2>
Explanation:
Here momentum is conserved.
Initial momentum = Final momentum.
Initial momentum = Momentum of hockey puck
Mass of hockey puck = 0.115 kg
Velocity of hockey puck = 35 m/s
Initial momentum = 0.115 x 35 = 4.025 kg m/s
Final momentum = Momentum of puck and the octopus
Combined mass = 0.115 + 0.265 = 0.38 kg
Let v be the speed.
Final momentum = 0.38 x v = 0.38 v
We have
4.025 = 0.38v
v = 10.59 m/s
Velocity of puck and the octopus is 10.59 m/s.
Answer:earth, water, air, fire, and (later) aether, which were proposed to explain the nature and complexity of all matter in terms of simpler substances.
Explanation:
Explanation:
a potassium ion has a charge of 1+.
Magnesium is in the second column and therefore has 2 electrons in its outermost shell. It would tend to lose two electrons and form a +2 ion. Potassium is in the first column and therefore has 1 electron in its outermost shell. It would tend to lose one electron and form a +1 ion.
