Answer:
basaltic cinder cone
Explanation:
The volcano consists of a black ("negro") basaltic cinder cone with associated lava flows, including an aa flow field reaching 4 km to the NE and SW. The frequent eruptions of Cerro Negro have modified its morphology continuously since its birth 160 years ago
Answer:
d = 1.82 10⁻⁶ m = 1.82 μm
Explanation:
The diffraction phenomenon is explained by a similar equation Young's double slit equation
d sin θ = n λ
Where d is the spacing between the bars, θ is the angled diffraction, n in an integer representing the order of diffraction and λ is the wavelength of light
Let's calculate
d = n λ / sin θ
d = 1 470 10⁻⁹ /sin 15
d = 1.82 10⁻⁶ m = 1.82 μm
Answer:
So, you're going to need the equation ρ = ρo [1 + α(T-To)]
1.59x10^-8 ohms*m is your ρo because that is measured at your reference temperature (To), 20◦C. T is your 6◦C and α is 0.0038(◦C)−1. So, using that you solve for ρ. If you keep up with the units though, you notice it comes out to be ohms*m and that isn't what you want.
So, the next equation you need is J=σE where E is your electric field (3026 V/m) and σ is the electrical conductivity which is the inverse of your answer you got in the previous equation. So find the inverse of that answer and multiply it by your electric field and that will give you the current density.
I hope this helps!
Explanation:
The movement of material due to differences in density that are caused by differences in temperatures is called CONVECTION.
Engineering controls could involve altering the weight of the products, adjusting the heights of the work surfaces, or getting lifting equipment. Administrative controls are workplace policies, practices, and processes that reduce the likelihood of risky situations for employees.
<h3>What are Engineering controls?</h3>
- Engineering controls are methods for preventing dangerous situations for workers by erecting a barrier between them and the danger or by ventilating the area to remove any hazardous materials.
- Instead of depending on employee behavior or mandating that employees wear safety gear, engineering controls entail making physical changes to the workplace itself.
<h3>What is Administrative controls?</h3>
- Administrative controls are policies, procedures, shift designs, or training that reduce the threat of a hazard to a person.
- Typically, administrative controls aim to alter people's behavior (such as that of manufacturing workers) rather than eliminating the real risk or provide personal protective equipment (PPE).
