What is the wave length of the instruments playing at this frequency if the speed of sound is 342m/s

Answers

Answer:

6.84m

Explanation:

The question you asked didn't specify the frequency of the instrument, so I'm going to assume for the question sake.

For the question, we will use the formula

λ = V/F, where

λ = the wavelength we're looking for

V = Velocity of the sound

F = frequency of sound.

Assuming that the frequency of the instrument is 50Hz.

λ = 342/50

λ = 6.84 m

True or False. Can Metalloids conduct electricity under certain conditions?

Answers

Answer:

Conduction: Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semi-conductors. Luster: Silicon for example appears lustrous, but is not malleable or ductile (it is brittle - a characteristic of some nonmetals).

Answers

The answer is 1000x10= 10000N
The force should be its weight. This is the force (gravitational) between the Earth and the elevator...the only thing is that the Earth is too massive to "see" the effect of this force (movement) while you see the elevator speeding towards the Earth (with acceleration
g
).

If we want to reach the planet PSR B1620-26 b, explain why we will need to make some big “wrinkle in time” discoveries or find ways to live much, much longer?

Answers

Answer:

Given the information that PSR B1620-26 b is the oldest planet in the Milky Way, it is estimated to be about 13 billion years old, the planet is approximately 12,390 light-years away from Earth, this means that it would take 460,908,000 years to arrive at the ancient planet. If we want to reach this planet, we are going to need to make some gig “wrinkle in time” discoveries, or find ways to live much longer, considering that the current lifespan of humans is only 79 years.

Two resistors, one with 7.00 Ω of resistance and the other with 11.00 Ω of resistance, are connected in series to a 9.00 V battery. How much power is dissipated by these two resistors?

Answers

Answer:

4.5 W

Explanation:

Applying,

P = V²/(R₁+R₂).................. Equation 1

Where P = Power, V = Voltage, R₁ and R₂ = values of the two resistor.

From the question,

Given: V = 9.00 V, R₁ = 7.00 Ω, R₂ = 11.00  Ω

Substitute these values into equation 1

P = 9²/(7+11)

P = 81/(18)

P = 4.5 Watt.

Hence the power dessipated by the two resistors is 4.5 watt

Solution :

[tex] \large\boxed{ \mathrm{volume = \pi {r}^{2}h }}[/tex]

[tex]220 = \dfrac{22}{7} \times 3 \times 3 \times h[/tex]

[tex] \dfrac{220 \times 7}{22 \times 3 \times 3} = h[/tex]

Answer:

0.078 inches

Explanation:

The volume of a cylinder is [tex]V=\pi r^{2} h[/tex]. [tex]r[/tex] is the radius of the cylinder, [tex]h[/tex] is the height of the cylinder, and [tex]V[/tex] is the total volume.We can divide both sides by [tex]9\pi[/tex] to isolate the height. We now have [tex]\frac{220}{9\pi }=h[/tex].We can plug in [tex]220[/tex] for the value of [tex]V[/tex], and insert 3 as [tex]r[/tex]. Now, we have [tex]220 = \pi (3^2)(h)[/tex].We can simplify the right side by finding the value of [tex]3^2[/tex], which is [tex]3*3[/tex], or [tex]9[/tex]. We now have [tex]220 = 9\pi h[/tex].Divide both sides by [tex]9\pi[/tex] so we can isolate the height! We now have [tex]\frac{220}{9\pi }=h[/tex].It would be best to use a calculator at this point. Plug the above equation into a calculator; otherwise, replace [tex]\pi[/tex] with [tex]3.14[/tex] and simplify the fraction. You should get about [tex]07.7809...[/tex] which we can round to the nearest hundredths (since this is Geometry, I am assuming you know how to round).Our final answer is [tex]07.78[/tex] inches.

Answer: Last option (total energy always remains constant)

Explanation:

The Law of Conservation basically states that energy cannot be created or destroyed. Only changed from one form to another (potential, kinetic, chemical, etc.) so it makes sense that the net energy is unchanging.

Calculate the amount of heat gained by 114.32 grams of water at 14.85C raised to 18.0C. The heat capacity of water is 4186J/kgC.

Answers

Answer:

1.51 × 10⁶ kJ

General Formulas and Concepts:

Stoichiometry

Using Dimensional Analysis

Thermochemistry

Specific Heat Formula: q = mcΔT

q is heat (in J)m is mass (in g)c is specific heat formula (in J/g °C)ΔT is change in temperature (in °C)

Explanation:

Step 1: Define

[Given] m = 114.32 g

[Given] c = 4186 J/kg °C

[Given] ΔT = 18.0 °C - 14.85 °C = 3.15 °C

[Solve] q

Step 2: Convert Pt. 1

1 kg = 1000 g

[tex]\displaystyle 4186 \ J/kg \ ^\circ C(\frac{1000 \ g}{1 \ kg}) = 4186000 \ J/g \ ^\circ C[/tex]

Step 3: Solve

Substitute in variables [Specific Heat Formula]:                                            q = (114.32 g)(418600 J/g °C)(3.15 °C)Multiply:                                                                                                             q = (4.78544 × 10⁸ J/°C)(3.15 °C)Multiply:                                                                                                             q = 1.50741 × 10⁹ J

Step 4: Convert Pt. 2

1000 J = 1 kJ

[tex]\displaystyle 1.50741 \cdot 10^9 \ J(\frac{1 \ kJ}{1000 \ J}) = 1.50741 \cdot 10^6 \ kJ[/tex]

Step 5: Check

Follow sig fig rules and round. We are given 3 sig figs as our lowest.

Explanation:

Given the following data;

Velocity = 20 m/s

Radius, r = 25 m

To find the centripetal acceleration;

Mathematically, centripetal acceleration is given by the formula;

Centripetal acceleration = velocity²/radius

Centripetal acceleration = 20²/25

Centripetal acceleration = 400/25

Centripetal acceleration = 16 m/s²

Dibuja la gráfica de calentamiento de un kilogramo de plomo que se encuentra inicialmente a 70ºC y pasa a una temperatura final de 2000ºC, sabiendo que su temperatura de fusión es: 327.4ºC y la de ebullición es de 1725ºC

Answers

Answer:

Q= m [tex]c_e[/tex] ΔT and   Q = m L

Explanation:

For this graph of temperature vs energy (heating) we must use two relations

* for when there is no change of state

          Q= m [tex]c_e[/tex] ΔT

* for using there is change of state

          Q = m L

the second expression is a consequence of the fact that all the energy supplied is used to change the state of the solid-liquid and liquid-gas system

the energy supplied is the sum of the energy in each interval

divide the system into intervals determined by the state change points

1) from T₀ = 70ºC to T_f = 327.4ºC, sample in solid-liquid state

           c_e = 128 J / kg ºC

           Q₁ = m c_e (T_f -To)

           Q₁=1  128 (327.4 -70)

           Q₁ = 3.29 10⁴ J

           Q = Q₁ = 3.29 10⁴ J

2) when is it changing from solid to liquid

            L = 2.45 10⁴ J / kg

            Q2 = 1 2.45 10⁴

            Q2 = 2.45 10⁴ J

            Q = Q₁ + Q₂

             Q = 5.74 10⁴ J

3) from to = 327.4ºC until T_f = 1725ºC, sample in liquid state

in the tables the specific heat of the solid and liquid state is the same

             Q3 = m c_e (T_f -To)

             Q3 = 1 128 (1725 -327.4)

             Q3 = 1.79 10⁵ J

              Q = Q₁ + Q₂ + Q₃

              Q = (3.29 +2.45 + 17.9) 10⁴ J

              Q = 23.64 10⁴ J

4) for when it is changing from the liquid state to the gaseous state

             L_v = 8.70 10⁵ J / kg

             Q₄ = m L_v

             Q₄ = 1 8.70 10⁵

             Q₄ = 8.70 10⁵ J

             Q = Q₁ + Q₂ + Q₃ + Q₄

              Q = (3.29 +5.74 + 17.9+ 87.0) 10⁴ J

               Q = 110.64 10⁴ J

5) from To = 1725ºC to T_f = 2000ºC, sample in gaseous state

             Q₅ = m c_e ΔT

             Q₅ = 1 128 (2000 -1725)

             Q₅ = 3.52 10⁴ J

             Q = Q₁ + Q₂ + Q₃ + Q₄ + Q₅

              Q = 114.16 104 J

the following table shows the points to be plotted

         Energy (10⁴ J)  Temperature (ºC)

                  0                     70

                 3.29             327.4

                 5.74             327.4

               23.64           1725

               110.64          1725

                114.16         2000
