The appropriate response is infrared waves. Indeed, even in the darkest of conditions, there are modest bits of light present. Some of this light might be the infrared light that isn't obvious to the stripped eye. Night vision goggles utilizing picture upgrade innovation gather all the accessible light, including infrared light, and open up it with the goal that you can without much of a stretch see what's happening oblivious.
Answer:
6.54% is the required concentration of lithium in an alloy (Al–Li).
Explanation:
Suppose 100 grams of an alloy of aluminium and lithium.
Density of an alloy = d 
Volume of an alloy = V
Volume of aluminum = 
Mass of aluminum = x
Density of aluminum = 
Volume of lithium = 
Mass of lithium = y
Density of lithium= 
..[1]
..[2]
Solving [1] and [2] :
we get :
x = 93.46 g
y = 6.54 g
Concentration of Li (in wt%) that is required:
Answer:
the strength of gravitational force between two objects depends on two factors,mass and distance. the force of gravity the masses exert on each other. if one of the masses is doubled, the Force of gravity between the object is doubled. increases the force of gravity decreases.

Answer:
Contributes to the membrane potential.
Explanation:
Sodium-potassium pump: In cellular physiology, a protein which is identified in many cells that helping in to maintain the higher concentration of potassium ions inside than that is in the surrounding medium and maintain the lower concentration of sodium ions inside than that of the surrounding medium.
This unbalanced charge transfer contributes in the separation of charge across the cell membrane. Sodium-potassium pump is known for important contributor to action potential which is produce by nerve cells.
