when waterways are polluted it affects all forms of life in the area - including us
expression:
for example when Lakes streams and ponds are polluted it can kill or harsh fish and other Wildlife that lives there!
hope that helps !
Answer:
ammonia can be produced at ambient pressure from, air water and concentrated sunlight as a renewable source of process heat via nitrogen reduction with a looped metal nitride followed by separate hydrogenation of the lattice nitrogen into ammonia
Explanation:
nitride redox materials for solar driven ammonia systhesis
Answer: A. It consists of cranial and spinal nerves that spread throughout the body.
Explanation:
The peripheral nervous system (PNS) is made up of all nerves outside the central nervous system (CNS); includes all the cranial nerves that carry impulses to and from the brain and all the spinal nerves that carry messages to and from the spinal cord. This includes long nerve fibers as well as ganglia made of neural cell bodies. <em>The peripheral nervous system connects the central nervous system (CNS) to various parts of the body.</em>
The part of the body that constitutes the upper and lower extremities of the body along with the shoulder and pelvic girdles is the <em>appendicular skeleton.</em>
The part of the body that supports, protects, and allows bodily movement is <em>the skeleton</em><em>. </em><em>The skeleton</em> also provides the shape and form of the human body.
Answer: Density is defined as the mass per volume of a substance. Thus, air density is defined as the mass of air per unit volume. Using... Air pressure, or atmospheric pressure, is defined as the weight of air in Earth's (or another planet's) atmosphere.
Explanation:
Answer:
2 and 0.6 ohms = 1.8A
4ohms = 1.08A
6 ohms = 0.72 ohms
Explanation:
With the help of the given diagram calculate the current through each resistor.
According to ohms law
E = IRt
E is the electromotive force = 9V
I is the total current in the circuit
Rt is the total equivalent resistance
Get Rt
1/R = (1/4+1/6) (parallel resistors)
1/R = 3+2/12
1/R = 5/12
R = 12/5
R = 2.4 ohms
Rt = 2 + 0.6 + 2.4
Rt = 5 ohms
Get the total current
I = E/Rt
I = 9/5
I = 1.8A
Since same current flows in a series connected resistors
Current in the 2 and 0.6 ohms resistors will be 1.8A
For the 4 and 6 ohms resistor:
Voltage across them is expressed as:
V = IR
V = 1.8(2.4)
V = 4.32Volts
The current in 4 ohms resistor
I = 4.32/4
I = 1.08A
The current in 6 ohms resistor
I = 4.32/6
I = 0.72A
