How to solve it? Three capacitors with capacities of 600 pF, 300 pF, 200 pF are connected in series. The 60 V voltage is applied to the group. Calculate the voltage on each capacitor. Answer: 10V, 20V, 30V.

Answers

Answer:

1. Voltage across 600 pF is 10 V.

2. Voltage across 300 pF is 20 V.

3. Voltage across 200 pF is 30 V.

Explanation:

We'll begin by calculating the total capacitance of capacitor. This can be obtained as follow:

Capicitance 1 (C₁) = 600 pF

Capicitance 2 (C₂) = 300 pF

Capicitance 3 (C₃) = 200 pF

Total capacitance (Cₜ) =?

1/Cₜ = 1/C₁ + 1/C₂ + 1/C₃

1/Cₜ = 1/600 + 1/300 + 1/200

1/Cₜ = 1 + 2 + 3 / 600

1/Cₜ = 6/600

1/Cₜ = 1/100

Cₜ = 100 pF

Next, we shall convert 100 pF to Farad (F). This can be obtained as follow:

1 pF = 1×10¯¹² F

Therefore,

100 pF = 100 pF × 1×10¯¹² F / 1 pF

100 pF = 1×10¯¹⁰ F

Thus, 100 pF is equivalent to 1×10¯¹⁰ F.

Next, we shall determine the charge. This can be obtained as follow:

Voltage (V) = 60 V

Capicitance (C) = 1×10¯¹⁰ F

Charge (Q) =?

Q = CV

Q = 60 × 1×10¯¹⁰ F

Q = 6×10¯⁹ C

1. Determination of the voltage across 600 pF.

Capicitance 1 (C₁) = 600 pF = 6×10¯¹⁰ F

Charge (Q) = 6×10¯⁹ C

Voltage 1 (V₁) =?

Q = C₁V₁

6×10¯⁹ = 6×10¯¹⁰ × V₁

Divide both side by 6×10¯¹⁰

V₁ = 6×10¯⁹ / 6×10¯¹⁰

V₁ = 10 V

2. Determination of the voltage across 300 pF.

Capicitance 2 (C₂) = 300 pF = 3×10¯¹⁰ F

Charge (Q) = 6×10¯⁹ C

Voltage 2 (V₂) =?

Q = C₂V₂

6×10¯⁹ = 3×10¯¹⁰ × V₂

Divide both side by 3×10¯¹⁰

V₂ = 6×10¯⁹ / 3×10¯¹⁰

V₂ = 20 V

3. Determination of the voltage across 200 pF.

Capicitance 3 (C₃) = 200 pF = 2×10¯¹⁰ F

Charge (Q) = 6×10¯⁹ C

Voltage 3 (V₃) =?

Q = C₃V₃

6×10¯⁹ = 2×10¯¹⁰ × V₃

Divide both side by 2×10¯¹⁰

V₃ = 6×10¯⁹ / 2×10¯¹⁰

V₃ = 30 V

what is the gain in gpe when a brick of 2.00 kg is lifted up by 11.5 m


[ HELP NEEDED URGENTLY

Answers

Answer:

E = 225.4 J

Explanation:

Given that,

The mass of a brick, m = 2 kg

It is lifted up by 11.5 m

We need to find the gain in gravitational potential energy. The formula for gravitational potential energy is given by :

[tex]E=mgh\\\\E=2\times 9.8\times 11.5\\\\E=225.4\ J[/tex]

So, the gain in gravitational potential energy is 225.4 J.

5. A standing wave in a clothesline has 4 nodes and 3 antinodes. The clothesline is 12 m long and is vibrating

at 0.50 vibrations per second. What is the speed of the wave?

Answers

Answer:

  v = 4 m / s

Explanation:

In this exercise we are asked to find the speed of the wave, which is described by the expression

          v = λ f

in this case the wave has 4 nodes and 3 antinodes, in a length of 12 m

for a standing wave it is satisfied that we have a full wavelength and a half of another

          L = λ + ½ λ

          L = [tex]\frac{3}{2}[/tex] λ

          λ = ⅔ L

Cambien indicates that it has a frequency of

          f = 0.5 Hz

we substitute

          v = ⅔ L f

let's calculate

          v = [tex]\frac{2}{3}[/tex] 12 0.5

          v = 4 m / s

The final velocity of a car is 30m/s. The car is accelerating at a rate of 2.5m/s2
over an 2.8m/s2
8 second period of time. What is the initial velocity of the car?

Answers

Answer:

10m/s

Explanation:

Vf=v0+at

30m/s=v0+2.5m/s^2*8s

Solve for v0=10m/s

Sorry for the vague explanation I'm on my phone right now. Hope this still helps!

Initial velocity of the car where final velocity of a car is 30m/s and it is accelerating at a rate of 2.5 [tex]m/s^{2}[/tex] over an 2.8 [tex]m/s^{2}[/tex] 8 second period of time is 10 m/s.

To find the initial velocity of the car, we can use the kinematic equation:

Final velocity (v) = Initial velocity (u) + (Acceleration (a) * Time (t)).

Given the final velocity (v) as 30 m/s, acceleration (a) as 2.5 [tex]m/s^{2}[/tex], and time (t) as 8 seconds, we can plug these values into the equation:

30 m/s = u + (2.5 [tex]m/s^{2}[/tex] * 8 s).

Now, solve for the initial velocity (u):

30 m/s = u + 20 m/s.

Subtract 20 m/s from both sides:

u = 30 m/s - 20 m/s = 10 m/s.

Therefore, the initial velocity of the car is 10 m/s.

3. A sailor pushes a 160.0 kg crate up a ramp that is 2.50 m high and 15.0 m long onto a loading dock. He exerts a 620.0 N force parallel to the ramp. a) What is the mechanical advantage of the ramp? b) What is the efficiency of the ramp? Your response should include all of your work and a free-body diagram. Answer:

Answers

Answer:

1. The work done by the wind was 2.475 x 20^8 J.

The wind’s power was 4.4 x 10^5 W.

F = 3.50 x 10^4 N

S = 20.0 km = 20^4 m

W = 3.50 x 10^4 N x 20^4 m x cos 45 = 3.960 x 10^9 J

2.5 h = 9000 s

3.960 x 10^9/9000 = 4.4 x 10^5

2. If the lever is 100% efficient, the worker needs to push his side 0.735 m.

efficiency = work output/work input x 100

100 = 1250 x 0.1/170d x 100

100/100 = 125/170d

1 = 125/170d

170d = 125

d = 125/170

d = 0.735 m

3. work = force x distance

work = 620 x 15 = 9300 J

work = (160)(9.8)(2.50) = 3920 J

160 x 9.8 = 1568 N

1568/620 = 2.529

mechanical advantage = 2.529

(3920/9300) x 100% = 42.151

efficacy = 42.15%

When does the ball have the greatest and least amount of potential energy?

Answers

Answer:

A ball thrown into the air has the most potential energy when it has reached the highest point above the ground before it begins descending. If we consider the vertical motion only beginning when the ball leaves the thrower’s hand, the ball is exchanging kinetic energy for (gravitational) potential energy. When all of the kinetic energy has been transformed, the ball begins falling, and exchanges it’s potential energy back into kinetic energy. If you ignore air resistance, the ball will land with as much energy as it began with.

Sticky crashes': A 700 kg car is traveling at 10 m/s. It hits a 300 kg car that is parked. Their bumpers lock and the two roll forward together. With what velocity do they roll forward?​

Answers

Answer:

7 m/s

Explanation:

Find the total mass

m1+m2 = total mass

700kg+300kg = 1000kg

Find the velocity of each mass

v1 = 10m/s

v2 = 0m/s

Find the combined momentum

m1v1 + m2v2 = mfvf

(700)(10)+(300)(0)=(1000)(vf)

7000=1000(vf)

7=vf

So the velocity of the two cars rolling together is 7 m/s

A ball rolling at a speed of 4.30 m/s has a kinetic energy of 23.1 J. What is the mass of the ball?
PLEASE HELP

Answers

Answer:

Mass = 2.50 kilograms.

Explanation:

Given the following data;

Velocity = 4.3m/s

Kinetic energy = 23.1J

To find the mass of the ball;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the equation, we have

23.1 = ½m*4.3²

46.2 = 18.49m

Mass, m = 46.2/18.49

Mass, m = 2.498 ≈ 2.50kg
