Answer:
7.2V
Explanation:
Find the equivalent resistance:
Req = 10 ohms + 15 ohms = 25 ohms
Use ohm's law to find the current:
V = IR
12V = I(25 ohms)
I = .48 amps
Multiple the current with the value of R2 to get the voltage drop:
.48amps x 15 ohms = 7.2V
Answer:
B. 12.0A
Explanation:
The circuit shown in the image is a parallel circuit which mean that the voltage of the source is equal across each resistance in the circuit because they are directly connected to the terminals of the voltage source.
The voltage across the 10 Ohms resistor is 120V
So, let's proceed to calculate the current
By using Ohm's Law
12A is the amount of current flowing through the 10 ohms resistor.
Answer:
B. does it transfer energy
A wave is a disturbance in a medium. Particles vibrate and TRANSFER their ENERGY to their neighbors.
Answer:
1. Soil vapor extraction - 3
2. Air sparging - 1
3. bioventing - 4
4. Natural attenuation -2
Explanation:
Soil vapor extraction - Soil vapor extraction (SVE) is the method in which perforated pipes are used into the soil and air is injected through the pipes. Contamination in soil then removed through perforation in pipes and disposed into an off-gas treatment unit.
Air sparging - In air sparging process air is injected in bubble form that remediates groundwater by volatilizing contaminants and enhancing biodegradation.
Bioventing - In bioinventing process low air flow rates are used that provide enough oxygen to sustain microbial activity in the soil and remove other contamination form the soil.
Natural attenuation - Natural attenuation is a natural process of environmental remediation which reduce the toxicity, mass, or concentration of contaminants in soil without human intervention.
