The capacitors are disconnected from the potential difference without allowing them to discharge. They are then reconnected in p

arallel with each other, with the positively charged plates connected together. What is the voltage across each capacitor in the parallel combination?

Answer:

net voltage will become half that of initial voltage now

Explanation:

Initially two capacitors are connected across a given voltage difference

So the net charge on the two capacitors is given as

Q = C_{eq} V

Q = \frac{C}{2} V

now when these are connected in parallel with no change in charge

then total charge on each plate is given

Q = \frac{CV}{2} + \frac{CV}{2}

Q = CV

also we know that

C_{eq} = 2C

now we will have

V_{net} = \frac{Q_{net}}{C_{eq}}

V_{net} = \frac{CV}{2C} = \frac{V}{2}

so net voltage will become half that of initial voltage now

A car is traveling at 21.0 m/s. It slows to a stop at a constant rate over 5.00s. How far does the car travel during those 5.00
Doss [256]

Answer:

d = 105 m

Explanation:

Speed of a car, v = 21 m/s

We need to find the distance traveled by the dar during those 5 s before it stops. Let the distance is d. It can be calculated as :

d = v × t

d = 21 m/s × 5 s

d = 105 m

So, it will cover 105 m before it stops.

A block of ice of mass 4.30 kg is placed against a horizontal spring that has a force constant k = 250 N/m and is compressed a d
OleMash [197]

Answer:

W = 0.060 J

v_2 = 0.18 m/s

Explanation:

solution:

for the spring:

W = 1/2*k*x_1^2 - 1/2*k*x_2^2

x_1 = -0.025 m and x_2 = 0

W = 1/2*k*x_1^2 = 1/2*(250 N/m)(-0.028m)^2

W = 0.060 J

the work-energy theorem,

W_tot = K_2 - K_1 = ΔK

with K = 1/2*m*v^2

v_2 = √2*W/m

v_2 = 0.18 m/s

A boy on rollerskates is travelling along at 8 m/s. He has a mass of 60 kg and is carrying his
Brrunno [24]

Answer:

6m/s

Explanation:

the original momentum = mass x velocity = 8x (60+10) = 560

momentum after = mass x velocity of the school bag + mass x velocity of the boy = 10x20 + 60x A

200+60A = 560

A=6
