Answer:
the voltage across the resistor is V= 0
Explanation:
The correct answer is zero.
The answer is zero because the inductor acts as open circuit.
![i= i_0[1-e^{-\frac{t}{\tau} }]](https://tex.z-dn.net/?f=i%3D%20i_0%5B1-e%5E%7B-%5Cfrac%7Bt%7D%7B%5Ctau%7D%20%7D%5D)
i_o= maximum current
\tau= L/R= time constant
i= current at any instant
![V= V_0[1-e^{-\frac{t}{\tau} }]](https://tex.z-dn.net/?f=V%3D%20V_0%5B1-e%5E%7B-%5Cfrac%7Bt%7D%7B%5Ctau%7D%20%7D%5D)
at t=0 at the moment when contact is made
V=V_o[1-1]
⇒V= 0 V
Answer:
Point motion will eventually stops due to action of g exactly perpendicular...
Explanation:
If ignoring the air resistance, the magnitude of gravitational acceleration is already strong enough to stops the acceleration. As we know that, the spring constant of a bungee spring cord will be F = -k/x, where x is the stretched length and k is the spring constant of bungee cord. If F = ma = w = mg, the g = -m k/x. Now we can clearly see that the value of g remains constant due to the fluctuating length of the cord as the motion progresses back and forth in SHM say from x1 to x2 and x2 to x1.
Answer:
Gray-ish looking like as if the atmosphere were full of only pollution.
Answer: hes not a country singer if thats what your asking
Explanation:
Answer:
22J
Explanation:
Given :
radius 'r'= 3cm
rotational inertia 'I'=4.5 x 
kgm²
mass on one side of rope '
'= 2kg
mass on other side of rope'
' =4kg
velocity'v' of mass ' = 2m/s
Angular velocity of the pulley is given by
ω = v /r => 2/ 3x 
ω = 66.67 rad/s
For the rotating body, we have
KE = 
I ω²
= 10J
Next is to calculate kinetic energy of the blocks :
=12J
Therefore, the total kinetic energy will be
KE = 
=10 + 12
KE= 22J
