A resistor and an ideal inductor are connected in series to an ideal battery having a constant terminal voltage V 0. (a) At the

dybincka [34]

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.

$i= i_0[1-e^{-\frac{t}{\tau} }]$

i_o= maximum current

\tau= L/R= time constant

i= current at any instant

$V= V_0[1-e^{-\frac{t}{\tau} }]$

at t=0 at the moment when contact is made

V=V_o[1-1]

⇒V= 0 V

hot-air balloon is ascending at the rate of 14 m/s and is 84 m above the ground when a package is dropped over the side. (a) How

timurjin [86]

Answer:

a) t = 4.14 s

b) Speed with which it hits the ground = 40.58 m/s

Explanation:

Using the equations of motion,

g = 9.8 m/s², y = H = 84 m,

Initial velocity, u = 0 m/s,

final velocity, v = ?

Total Time of fall, t = ?

a) y = ut + gt²/2

84 = 0 + 9.8t²/2

4.9t² = 84

t² = 84/4.9

t = 4.14 s

b) v = u + gt

v = 0 + (9.8 × 4.14)

v = 40.58 m/s
