write a function called sum_of_cubes that takes two numbers as arguments and returns the sum of their cubes.
Answers
To write a function called sum_of_cubes that takes two numbers as arguments and returns the sum of their cubes, we can define the function in the following way:
```
def sum_of_cubes(num1, num2):
sum = num1**3 + num2**3
return sum
```
In this function, we first define two input parameters, `num1` and `num2`. We then use the `**` operator to raise each input number to the third power, or cube. We add the two resulting values together and assign the sum to a variable called `sum`. Finally, we return the value of `sum`.
For example, if we call the function with the arguments `2` and `3`, the function will return `35`, which is the sum of the cubes of `2` and `3` (i.e., `2**3 + 3**3 = 8 + 27 = 35`).

Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. Technician B says that latent heat is hidden heat that is required for a change of state of matter. Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B
Answers
Answer: C
Both A and B are correct
Explanation:
Latent heat is the hidden heat.
Latent heat is the heat energy required to change one state of matter to another state of matter without change in temperature. For example, solid state to liquid state, or liquid state to gaseous state.
Thermometer can not detect the latent heat. That is why it is called hidden heat.
If Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. And Technician B says that latent heat is hidden heat that is required for a change of state of matter, then we can therefore conclude that both Technician A and Technician B are correct.

Which of the following did Dropbox implement after a series of security snafus in 2011 and 2012?
a. firewall
b. SSL/TLS
c. two-factor authentication
d. anti-virus software
Answers
Dropbox implemented the two-factor authentication feature after a series of security snafus in 2011 and 2012. The two-factor authentication feature is used for an extra layer of security to prevent unauthorized access.
After a series of security incidents in 2011 and 2012, Dropbox implemented several measures to enhance its security. One of the measures they implemented was two-factor authentication (2FA). This added an extra layer of security by requiring users to provide an additional verification step, typically a code sent to their mobile device, in addition to their password when logging into their accounts. Two-factor authentication helps protect against unauthorized access, even if the password is compromised.
While it is likely that Dropbox also implemented other security measures, such as firewalls and anti-virus software, specific information about those measures being implemented as a direct response to the security snafus is not readily available. However, SSL/TLS (Secure Sockets Layer/Transport Layer Security) was likely already in use by Dropbox even before the security incidents as it is a common security protocol used for encrypting data transmitted over the internet.

what is the transfer function? what is the steady-state error, ess? what is the natural frequency? you can assume ra
Answers
The transfer function is a mathematical representation of the relationship between the input and the output of a system. The steady-state error, or ess, is the difference between the desired output and the actual output when the system reaches a steady state. The natural frequency is the frequency of the system's response without any external forces.
Transfer Function: Transfer Function is used in signal processing, control engineering, and other disciplines that deal with systems or signals. The ratio of output to input in Laplace transform is known as the transfer function.
Steady-State Error: The error that happens when the system is at a stable state is referred to as a steady-state error. The difference between the desired and actual response is known as steady-state error. A system's ability to track a specific input as time progresses is characterized by this kind of error. If the input signal is a unit step, then the steady-state error is referred to as the static error coefficient. The coefficient of the steady-state error is frequently used to classify systems in control engineering.
Natural Frequency: Natural frequency is a term used in physics to describe how quickly an object vibrates when it is set in motion. The number of oscillations made by a system in a given time period without any external force acting on it is referred to as its natural frequency. A natural frequency is a measure of a system's stiffness and mass. In a control system, it is the frequency at which the system oscillates in the absence of any input.

hat is the frequency of a clock waveform whose period is 50 microseconds 10 kHz 20 kHz 100 MHz 100 kHz Keep in mind, the frequency f = 1/period. f = 1/T
Answers
The frequency of the clock waveform with a period of 50 microseconds is 20 kHz.
Frequency is a fundamental concept in physics and engineering that refers to the number of occurrences of a repeating event or phenomenon within a specific time interval. It is typically measured in hertz (Hz), which represents the number of cycles or oscillations per second.
To calculate the frequency, we can use the formula:
f = 1 / T
where f is the frequency and T is the period.
In this case, the period is given as 50 microseconds. To convert microseconds to seconds, we divide by 1,000,000:
T = 50 microseconds / 1,000,000 = 0.00005 seconds
Now we can calculate the frequency:
f = 1 / T = 1 / 0.00005 = 20,000 Hz = 20 kHz.

what is the thermo-elastic stress-strain relationship? write out the equation and explain the definition of each term involved. g
Answers
The thermo-elastic stress-strain relationship is important in understanding the behavior of materials under different thermal and mechanical conditions, and it has important implications for the design and performance of many engineering systems.
This relationship can be expressed mathematically through the following equation:σ = EαΔT + Eε
where σ represents stress, E represents the modulus of elasticity, α represents the coefficient of thermal expansion, ΔT represents the change in temperature, and ε represents strain.The first term on the right-hand side of the equation represents the thermal stress that develops in a material as a result of a change in temperature. This stress is caused by the material expanding or contracting due to changes in its dimensions resulting from changes in temperature.The coefficient of thermal expansion, α, is a measure of the material's sensitivity to temperature changes and represents the fractional change in length per degree of temperature change.The second term on the right-hand side of the equation represents the mechanical strain that occurs as a result of external forces acting on the material. This term is independent of temperature and represents the material's response to an applied load.

It is important to know the number of teeth on the two gears when calculating a bevel gear because the number of teeth determines the gear ratio, which in turn determines the torque and speed at which the gears will operate.
How to calculate the gear ratio?The gear ratio is calculated by dividing the number of teeth on the driving gear by the number of teeth on the driven gear.
If the number of teeth is not known, it would be impossible to accurately calculate the gear ratio and determine the performance of the gear set.
Additionally, the number of teeth also affects the meshing pattern and the contact ratio between gear teeth, which is also important to the gear's performance.

Mass media is not typically considered a social institution.
Instead, it is often regarded as a societal subsystem or a form of communication and information dissemination. Social institutions, on the other hand, are recognized as established systems or structures that fulfill specific functions and play crucial roles in society.
Let's briefly discuss the other options:
b. Peer group: Peer groups, consisting of individuals of similar age, social status, or interests, are considered social institutions. They provide a context for socialization, support, and the development of shared norms and values.
c. Healthcare: Healthcare is recognized as a social institution. It encompasses various organizations, professionals, and systems that provide medical services, promote public health, and address individual and community well-being.
d. Government: Government is a fundamental social institution responsible for establishing and enforcing laws, maintaining social order, providing public services, and managing governance and decision-making processes within a society.
It's worth noting that the classification of social institutions may vary among sociologists, and there can be debates and variations in their definitions. However, in general, mass media is not typically considered a social institution due to its distinct characteristics and functions compared to recognized social institutions like education, family, religion, economy, healthcare, and government.
