The maximum sample rate of a single software receiver in kHz is dependent on the specifications of the software receiver, as there is no standard value for this.
The maximum sample rate is a parameter of the receiver, which determines the highest frequency of signals that the software receiver can detect with the highest degree of accuracy.
Therefore, to determine the maximum sample rate of a particular software receiver, it is important to check the specifications provided by the manufacturer.
Additionally, there are various other factors that can impact the sample rate of a software receiver, including the processing power of the computer being used, the design of the software, and the complexity of the algorithms used to detect and demodulate signals.

how much heat needs to be removed from 100 g of 85°c water to make -5°c ice?
The amount of heat that needs to be removed from 100 g of 85°c water to make -5°c ice is 70194 J of heat.
What is the heat change when 100 g of 85°C water changes to -5°C ice?The amount of heat that needs to be removed is calculated below.
Heat changes involved are as follows:
Heat change from water at 85°C to water at 0°C = mc₁ΔT₁
Heat change from water at 0°C to ice at 0°C = mL
Heat change from ice at 0°C to ice at -5°C = mc₂ΔT₂
where
m is mass = 100 g
c₁ is the specific heat capacity of water = 4.184 J/g/K
ΔT₁ is temperature change = 85°C
L is the latent heat of fusion of ice = 336 J/g
c₂ is the specific heat capacity of ice = 2.06 J/g/K
ΔT₁ is temperature change = 5°C
Heat change = (100 * 85 * 4.184) + (100 * 336) + (100 * 5 * 2.06)
Heat change = 70194 J

what is the frequently of wave that wave has a wavelength of 0.39 m and a speed of 86 m/s?
The frequency of wave that wave has a wavelength of 0.39 m and a speed of 86 m/s is 220.5 Hz
v = λ / T
f = 1 / T
v = f λ
v = Wave speed
λ = Wavelength
T = Time period
f = Frequency
λ = 0.39 m
v = 86 m / s
f = v / λ
f = 86 / 0.39
f = 220.5 Hz
This equation is just a different version of velocity formula which is distance divided by time. In terms of a wave the distance is wavelength and time is time period T.

Find the magnitude of the torque that acts on the molecule when it is immersed in a uniform electric field of 6.19×105 N/C with its electric dipole vector at an angle of 69.9∘ from the direction of the field.
Answer:
\(\tau=5.81\times 10^5p\ N-m\)
Explanation:
We have,
Electric field, \(E=6.19\times 10^5\ N/C\)
The electric dipole vector at an angle of 69.9 degrees from the direction of the field.
The torque acting on a molecule is given by :
\(\tau=p\times E\\\\\tau=pE\sin\theta\)
p is electric dipole moment
\(\tau=p\times 6.19\times 10^{5}\times \sin (69.9)\\\\\tau=5.81\times 10^5p\ N-m\)
So, the magnitude of the torque acting on the molecule is \(5.81\times 10^5p\ N-m\).

Given:
• Distance = 150 km
,• Speed = 50 km/hr
Let's find the time it will take to cover the distance in minutes.
To find the distance, apply the formula:
\(time=\frac{distance}{speed}\)Thus, we have:
\(\text{time}=\frac{150}{50}=3\text{ hours}\)The time in hours is 3 hours.
To convert the time from hours to minutes, we have:
60 minutes = 1 hour
3 hours = 3 x 60 = 180 minutes
Therefore, it time in minutes is 180 minutes.

at what pressure range does the technician valve off the vacuum pump when evacuating to a deep vacuum?
When transferring a vacuum furnace chamber from atmospheric pressure to a supposedly "rough" vacuum, the roughing valve is utilized (typically in the range of 10 -2 to 10 -3 Torr).
This degree of vacuum is sometimes sufficient to carry out the targeted process. Another common name for vacuum is negative pressure (or soft vacuum). This happens when an application needs to keep track of both pressure increases and pressure drops in both directions above and below the atmosphere. The difference in pressure between the exhaust exit and input provides the basis for a vacuum.
We all know that water and air travel from high altitude to low altitude, and that a vacuum is produced by a difference in pressure between the two.

According to Coulomb's law, what happens to the attraction of two oppositely charged objects as their distance of separation increases?
(a) increases (b) decreases
(c) remains uncharged (d) cannot be determined
Answer:
Option B. Decreases
Explanation:
Coulomb's law states that:
F = Kq₁q₂ / r²
Where:
F => is the force of attraction between two charges
K => is the electrical constant.
q₁ and q₂ => are the two charges
r => is the distance apart.
From the formula:
F = Kq₁q₂ / r²
The force of attraction (F) is inversely proportional to the square of their separating distance (r).
This implies that as the distance between them increase, the force of attraction between the two charges will decrease and as the distance between two charges decrease, the force of attraction between them will increase.
Considering the question given above and the illustration given above, the force of attraction will decrease as their distance of separation increases.
Option B gives the right answer to the question.

A wave pulse travels along a string at a speed of 200 cm/s. Note that parts a - d are independent and refer to changes made to the original string.
If we quadruple mass and length then m = 4m_0 and L = 4L0. So the speed v is:
V =\(\sqrt{\frac{FL}{m} }\)
V = \(\sqrt{\frac{F_{0} 4L_{0} }{4m_{0} } }\)
V = \(\sqrt{\frac{F_{0} L_{0} }{m_{0} } }\)
v = \(V_{0}\)
V= 200 cm/s.
In a wave, the impulse propagating in the string is reflected off the solid wall to which the string is attached, as shown in the figure. Below he gives two statements about this situation. The reflected pulse has the same orientation as the incident pulse with a phase change of π radians. The velocity of a wave on a string depends on the square root of the stress divided by the mass per length, or linear density.
In general, the velocity of a wave through a medium depends on the elastic properties of the medium and the inertial properties of the medium. As the wave momentum moves through the fixed end, the rope end exerts a restoring force in the opposite direction to the wave amplitude, producing a reflected wave of negative amplitude propagating to the left. A sinusoidal wave is an example of a transverse wave because the chord moves up and down at right angles to the horizontal motion of the wave.

A shell explodes into two fragments, one fragment 25 times heavier than the other. If any gas from the explosion has negligible mass, then the momentum change of the heavier fragment is 25 times as great as them fragment. the momentum change of the lighter fragment is 25 times as great as the momentum ct of the fragment. the kinetic energy change of the heavier fragment is 25 times as great as the kinetic energ lighter fragment hea the kinetic energy change of the lighter fragment is 25 times as great as the kinetic energy change heavier fragment the momentum change of the lighter fragment is exactly the same as the momentum change of the heavier fragment
Thus, the momentum change of the heavier fragment is 25 times as great as that of the lighter fragment, and the kinetic energy change of the heavier fragment is also 25 times as great as that of the lighter fragment.

what is the frequency of a wave that travels 20 m/s with a wavelength of 200 meters?
The frequency of a wave is the number of cycles it completes in a given period of time, and it can be calculated using the following equation: frequency = velocity/wavelength. In the case of this wave, the frequency is 0.1 Hz (or 10 cycles/second).

Answer:The continuity equation for a compressible liquid is a mathematical expression that relates the changes in fluid density, velocity, and volume to the changes in time. This equation can be written as:
∂ρ/∂t + (ρv)•∇ = 0
where:
ρ = fluid density
v = fluid velocity
∂/∂t = partial derivative with respect to time
∇ = del operator
The continuity equation expresses the principle of mass conservation, stating that the rate of change of fluid density in a fixed volume must be equal to the rate of flow of fluid into or out of that volume. This equation is commonly used in fluid dynamics to study the behavior of liquids and gases in various applications, such as in pipelines, pumps, valves, and compressors.
