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

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

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.

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.

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

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.

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%

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
