Answer: A resistor, which converts some electric energy to light and thermal energy.

Explanation:

A bulb filament is made of resistor which allows the current to pass. Usually the metal- Tungsten is used to make the filament. A filament is a wire in the bulb through which current passes and it glows.  Joule heating phenomenon is used. The electrical energy is converted to heat and light energy by the resistor when current passes through it.

Tungsten has a very high melting point, it is hard and high thermal stability. Thus, it makes the best bulb filament.

A proton is released in a uniform electric field, and it experiences an electric force of 5 X 10^-10 N toward the South. What is
Ymorist [56]

Answer:

Electric field on proton

E=3.12\times 10^9\ N/C

Explanation:

Given that

Force,F=5\times 10^{-10}\ N

We know that

Charge on proton

q=1.6\times 10^{-19}\ C

We know that

Force = Electric field x Charge

F= E x q

E=\dfrac{F}{q}\ N/C

E=\dfrac{5\times 10^{-10}}{1.6\times 10^{-19}}\ N/C

E=3.12\times 10^9\ N/C

Electric field on proton

E=3.12\times 10^9\ N/C

Explain how the information from the stimuli is communicated to the brain.
irakobra [83]

Answer:

Answer:Neurons communicate through an electrochemical process. Sensory receptors interact with stimuli such as light, sound, temperature, and pain which is transformed into a code that is carried to the brain by a chain of neurons. Then systems of neurons in the brain interpret this information.

According to a college survey, 22% of all students work full time. find the mean for the number of 3) students who work full tim
attashe74 [19]

Assuming that the students worldwide are being considered, because of the extremely large population, this can be considered as a binomial distribution. A normal distribution is used most usually as a fair approximation of the binomial. The mean is the expectation, therefore:<span>
E[x] = np = (16)(0.22) = 3.52 
<span>μ = 3.52 </span></span>
