When a certain air-filled parallel-plate capacitor is connected across a battery, it acquires a charge of 200 µC on each plate.
Vika [28.1K]

Answer:

The value is \epsilon =  2.25

Explanation:

From the question we are told that

The charge acquired on each plate is q =  200 \mu C  =  200 *10^{-6} \  C

The additional charge accumulated on each plate is q_a =  250 \mu C  =  250 *10^{-6} \ C

Generally the capacitance of the capacitor before a dielectric slab is inserted is

C_i =  \frac{q}{V}

=> C_i =  \frac{200 \mu C}{V}

Generally the total charge on each plate of the capacitor when the dielectric slab was inserted is

Q =  q + q_a

=> Q = ( 200 + 250 ) \mu C

=> Q = 450 \mu C

Generally the capacitance of the capacitor after a dielectric slab is inserted is mathematically represented as

C =  \frac{450 \mu C}{V}

Generally the dielectric constant is mathematically represented as

\epsilon =  \frac{C}{C_i}

=>      \epsilon =  \frac{450 \mu C}{200  \mu C}

=>       \epsilon =  2.25

When a carpet is beaten with a stick dust particles off<br> ...why
Luda [366]

Answer:

An object's inertia tends to resist any change in its state of rest or motion. If a carpet is beaten with a stick then the carpet begins to move. But, the particles of dust are trying to resist their state of rest.

Jim began a 153-mile bicycle trip to build up stamina for a triathlon competition. Unfortunately, his bicycle chain broke, so he
NARA [144]

consider the motion when Jim travels by bicycle

D = total distance to be traveled for the trip = 153 mile

v = speed of riding = 42 mph

t = time taken to complete the trip by bicycle = ?

using the equation

t = D/ v

inserting the values

t = 153/42

t = 3.64  h

while walking and riding :

T = total time taken to complete the trip by walking and riding = 5 hours

t ' = time of walking = T - t = 5 - 3.64 = 1.36 hours

v' = speed of walking = 4 mph

d' = distance traveled by walking = ?

distance traveled by walking is given as

d' = v' t'

d' = 4 x 1.36

d' = 5.44 miles

d = distance traveled by bicycle = D - d' = 153 - 5.44 = 147.56 miles

v = speed of riding = 42 mph

t = time spent on the bicycle = ?

time spent on the bicycle is given as

t = d/v

t = 147.56/42

t = 3.51 hours
