A centigrade and fahrenheit thermometer are placed in hot water. The water is cooled. What fall of temperature will the fahrenheit thermometer register when the centigrade thermometer registers the fall in temperature as 45 degrees?​

The equivalent capacitance of this system is approximately 8.0 µF.

The energy stored in 9.0 µF is 56250 J.

The potential difference across the 5 µF capacitor is given by 1.6 × 10⁻⁶ times the potential difference V₂.

To find the equivalent capacitance of the system, use the concept of capacitance in series and parallel combinations.

(a) Capacitors in series:

1/C_eq = 1/C₁ + 1/C₂ + 1/C₃ + 1/C₄

Substituting the given values:

1/C_eq = 1/5.0 µF + 1/10.0 µF + 1/9.0 µF + 1/8.0 µF

Converting 8.0 µF to Farads:

1/C_eq = 1/5.0 µF + 1/10.0 µF + 1/9.0 F + 1/(8.0 × 10⁻⁶ µF)

Calculating the sum:

1/C_eq = 0.2 + 0.1 + 0.111 + 125000

Taking the reciprocal of both sides:

C_eq = 1 / (0.2 + 0.1 + 0.111 + 125000)

Calculating the value of C_eq:

C_eq ≈ 7.99999 µF or approximately 8.0 µF

(b) To calculate the energy stored in the 9.0 µF capacitor, use the formula:

E = (1/2) × C × V²

Substituting the given values:

E = (1/2) × 9.0 µF × (50.0 V)²

Calculating the energy:

E = (1/2) × 9.0 µF × 2500 V²

E = 56250 J

The energy stored in the 9.0 µF capacitor is 56250 J.

(c) To calculate the potential difference across the 5 µF capacitor, use the formula:

C₁ × V₁ = C₂ × V₂

Substituting the given values:

5.0 µF × V₁ = 8.0 µF × V₂

Converting 8.0 µF to Farads:

5.0 µF × V₁ = 8.0 × 10⁻⁶ µF × V₂

Simplifying:

V₁ = (8.0 × 10⁻⁶ µF / 5.0 µF) × V₂

V₁ = 1.6 × 10⁻⁶ × V₂

The potential difference across the 5 µF capacitor is given by 1.6 × 10⁻⁶ times the potential difference V₂.

Answer:

I KNOW THE ANSWER IT WILL COST 30$

Explanation:

The surface velocity is approximately 2.07 m/s.

The average velocity of the liquid flow per unit depth,

Q/A = 1.25 [gal/min]/[1 ft x 0.5 in x (1/12) ft/in] = 10 [ft/min]

where Q is the flow rate and A is the cross-sectional area of the channel.

Use the laminar velocity profile to determine the velocity at the center of the channel (y=0),

u(y=0) = Uo(2(0) - 0^2)/(2h) = 0

Since there is no slip at the wall, the velocity at y=h/2,

u(y=h/2) = Uo(2(h/2) - (h/2)^2)/(h)

= Uo(2-h/2)

= 2Uo - Uh/2

Equating this to the average velocity,

2Uo - Uh/2 = 10 [ft/min]

Solving for Uo = (10 + Uh/2)/2

Uh = Ahu(y=h/2) = AhUo(2-h/2)/(h) = A*Uo(2-h/2)

Substituting A = 1 [ft^2] and h = 0.5 [in] = 0.042 [ft], we get:

Uh = Uo(2-0.042/2) = 0.979Uo

Uo = (10 + 0.979Uo/2)/2

Uo = 6.8 [ft/min] or 2.07 [m/s]

Displacement = (14-20) Km = -6 Km

The displacement of a car is -6 Km South

The magnitude of the change in momentum is 36 kg m/s.

The momentum of an object is defined as the product of its mass and velocity.

The symbol for momentum is p. Its unit is kilogram meters per second (kg m/s). When a ball falls vertically onto a surface, the momentum is said to change.

The magnitude of the change in momentum can be found by calculating the difference between the initial momentum and the final momentum.

We can use the equation below to find the change in momentum.Δp = pf - pi

Where Δp is the change in momentum, pf is the final momentum, and pi is the initial momentum.The initial momentum of the ball can be found using the equation:

p = mv

where p is momentum, m is mass and v is velocity.

Therefore, the initial momentum of the ball is:

p = mv= 1.2 kg × 15 m/s= 18 kg m/s

The final momentum can be found using the same equation, but with a negative velocity since the ball is bouncing back with the same speed but opposite direction.

Therefore, the final momentum is:-18 kg m/s/

The change in momentum can now be calculated using the equation:

Δp = pf - piΔp = (-18 kg m/s) - (18 kg m/s)Δp = -36 kg m/s

Therefore, the magnitude of the change in momentum is 36 kg m/s.

The resultant of the displacement is 336.5m

The process of splitting a vector into its components is called resolution of the vector. The vectors are splitted into vertical and horizontal component.

For the first displacement;

The vertical component = - 150 sin45 = -106.1 m

The horizontal component = - 150 cos 45° = -106.1 m

For the second displacement;

The vertical displacement = - 85sin90 = -85

The horizontal component = 0

For the third displacement;

The vertical displacement = 550 sin55 = 450.5

The horizontal displacement = 550 cos 55 = 315.5

Sum of vertical component = 450.5-85-106.1 = 263.4

sum of horizontal component = 315.5 -106.1 = 209.4

Using Pythagorean theorem

R = √ 263.4² + 209.4²

R = √113227.92

R = 336.5m

The resultant angle = tan^-1( 263.4/209.4)

A car enters a corner and accelerates at 14 m/s² [S 10° E] for 6.5 s. It leaves the corner going 35 m/s [E 40° S].The car’s displacement during the corner is 365.95 meters, with a direction of S 81.4° E (measured from due south).

The term “displacement” refers to a change in an object's position. It is a vector measure with a magnitude and direction. It appears as an arrow that directs from the first position to the ending place.

We can break down the car's motion during the corner into horizontal and vertical components.

The horizontal component can be found using the initial and final velocities in the east direction:

=35 m/s cos(40°) - 0 m/s = 26.8 m/s

The time for which the car was accelerating can be used as the duration of motion in the south direction, so we can use the formula:

Δy = 1/2(14)(6.5 s)² = 365.125 m

Therefore, the displacement of the car during the corner is the vector sum of the horizontal and vertical components:

d = √(ΔxE)² + (ΔyS)²

d = √(26.8 m/s)² + (365.125 m)² = 365.95 m

Answer:

mAngleB= 50

mAngleC= 130

Explanation:

Complementary angles = 90

So If angle A is 40 subtract that to 90 to find angle B which is 50

and 50+40= 90 = Complementary !

Supplementary angles = 180

So if angle C is supplementary to angle B you would need to subtract 50 from 180 to find angle C which is 130

130+20= 180 = suplementary !

Value of Angle B is 50°.

Value of Angle C is 130°.

When two angles add up to 90 degrees, they are said to be complimentary angle.

When two angles add up to 180 degrees, they are said to be supplementary angle.

Given that:

angle A = 40°

Angle B is  a complement of Angle A.

so,

∠A + ∠B = 90°

∠B = 90° - ∠A = 90° - 40° = 50°

Again;  Angle C is a supplement of Angle B; so,

∠C + ∠B = 180°

∠C = 180° - ∠C = 180° - 50° = 130°

Hence, Angle B= 50° and Angle C= 130°.

Magnitude of vector A is  51.4 m and the angle of vector A with positive x-axis θ is 127.1° .

The quantities which have direction as well as magnitude is known as vector quantities .

We are given that ,

Ax is vector component on x -axis=−31m

Ay is vector component on y -axis=44m

Therefore, the magnitude of the vectors \(A_{x}\) and \(A_{y}\) is \(A\) which is given as,

\(A = \sqrt{A_{x} ^{2} }+ {A_{y} ^{2} }\\A = \sqrt{{-31} ^{2} }+ {41 ^{2} }}\\A = 51.4m\)

Thus, the magnitude of vector A will be 51.4 m

Now calculating the angle(θ) of the vector which make on the positive x axis, is given by the formula,

θ' = \(tan^{-1}\frac{Ax}{Ay}\)

θ' = \(tan^{-1}\frac{-31}{44}\)

θ' = \(-59.9\)°

Thus, here vector A is lies in 2nd quadrant which is  x-component of vector A that is negative and y-component is positive. So that from this to get the angle of vector with positive x-axis,

θ = 180° - θ'

θ=180 °- 52.9°

θ= 127.1°

Hence from above solution, the angle of vector A with positive x-axis θ is 127.1°

Answer:

2. ahead of the package.

Explanation:

Using y' - y = ut - 1/2gt², we find the time, t it takes the package to hit the ground. So, u = initial vertical velocity of package = 0 m/s, y = initial position of package = 3970 m, y' = final position of package = 0 m, g = acceleration due to gravity = 9.8 m/s².

Substituting the variables into the equation, we have

y' - y = ut - 1/2gt²

0 m - 3970 m = 0t - 1/2 × (9.8 m/s²)t²

-3970 m = -(4.9m/s²)t²

t² = -3970 m ÷ -4.9 m/s²

t² = 810.2 s²

t = √810.2 s²

t = 28.5 s

Using v = u' + at, we find the horizontal acceleration of the plane. Since the initial horizontal velocity of the package is that of the plane, u' = 162 m/s, v = 0 m/s since the package stops and t = 28.5 s when the package stops.

So, a = (v - u')/t

a = (0 m/s - 162 m/s)/28.5 s

a = -162 m/s/28.5 s

a = -5.68 m/s²

Using v² = u'² + 2as, we find the horizontal distance ,s where the package stops.

So, s =  (v² - u'²)/2a

Substituting the values of the variables, we have

s =  ((0 m/s)² - (162 m/s)²)/(2 × -5.68 m/s²)

= - 162 m²/s²/(-11.36 m/s²)

= 14.26 m

The horizontal distance d the plane moves after releasing the package is d = u't = 162 m/s × 28.5 s = 4617 m

Since d = 4617 m > s = 14.26 m, the plane would be ahead of the package when the package hits the ground.

The loudness is 90 phones, the sound intensity is 10^-7 W/m^2, and the power of the source is 0.0314 watts

(a) The loudness level in phones can be found using the formula:

Lp = 40 + 10 log(I/I0) + 10 log(f/f0) + G

Where Lp is the loudness level in phones, I is the sound intensity in watts/m^2, I0 is the reference sound intensity (10^−12 W/m^2), f is the frequency in Hz, f0 is the reference frequency (1000 Hz), and G is the frequency-dependent gain of the ear (in phones).

Substituting the given values, we get:

Lp = 40 + 10 log(I/10^-12) + 10 log(1000/1000) + G

Lp = 40 + 10 log(I/10^-12) + G

Since the sound level meter reading is 52 dB, the sound intensity can be found using the inverse square law of sound propagation:

L1 - L2 = 10 log(I1/I2)

52 - 0 = 10 log(I/10^-12)

I = 10^-7 W/m^2

Substituting this value in the above equation, we get:

Lp = 40 + 10 log(10^-7/10^-12) + G

Lp = 40 + 50 + G

Lp = 90 + G

Therefore, the loudness level of the clarinet sound at a distance of 5m is 90 phones (approximately).

(b) The sound intensity in watts/meter^2 can be calculated using the formula:

I = P/(4πr^2)

Where P is the power of the source in watts, and r is the distance from the source. Substituting the given values, we get:

I = P/(4π(5)^2)

Since we are interested in the sound intensity, we can rearrange this equation to solve for P:

P = I × 4πr^2

Substituting the given value of I, we get:

P = (10^-7 W/m^2) × 4π(5)^2

P = 0.0314 W

Therefore, the sound intensity of the clarinet sound at a distance of 5m is 10^-7 W/m^2, and the power of the source is 0.0314 watts.

(c) The power of the source can also be calculated using the formula:

                                           P = I × A

Where A is the surface area of a sphere with radius 5m (which is the surface area over which the sound energy is distributed).

Substituting the given value of I and the formula for surface area of a sphere (A = 4πr^2), we get:

P = (10^-7 W/m^2) × 4π(5)^2

P = 0.0314 W

Therefore, the power of the source is 0.0314 watts, which is consistent with the value obtained using the formula for sound intensity.

An observer on the spacecraft would see the light beam moving away from the ship at the speed of light, while an observer on Mars would also see the light beam moving away from the ship at the speed of light. This is because the speed of light is always constant, regardless of the motion of the observer or the light source.

When the ball is hit from the deck of the yacht at 100 mph, it is moving at a speed relative to the yacht.

Since the yacht is moving at 20 mph, the ball would appear to be moving away from the yacht at 100 mph.

This is because the speed of the ball relative to the yacht is 100 mph, while the speed of the yacht relative to the ground is 20 mph.

Therefore, the total speed of the ball relative to the ground would be the sum of the speed of the yacht and the speed of the ball relative to the yacht, which is 120 mph (20 mph + 100 mph).

Now let's consider the Hermes spacecraft traveling at 0.1c past Mars and shining a laser from the front of the ship.

According to the theory of relativity, the speed of light is always the same for all observers, regardless of their motion or the motion of the light source.

So, regardless of the speed of the spacecraft, the light beam would travel away from the ship at the speed of light, c.

An observer on the spacecraft would see the light beam moving away from the ship at the speed of light, while an observer on Mars would also see the light beam moving away from the ship at the speed of light.

This is because the speed of light is always constant, regardless of the motion of the observer or the light source.

In summary, the theory of relativity tells us that the speed of light is always the same for all observers, regardless of their motion or the motion of the light source.
