Answer:
Left amount of Polonium-210 after 115 days will be 4.5927 microgram
Explanation:
We have given initial mass of Polonium-210
Decay rate x= 0.502% = 0.00502
Time t = 115 days
We have to find the left amount of Polonium -210 after 115 days
We know that left amount is given by
So left amount of Polonium-210 after 115 days will be 4.5927 microgram
Answer:
When the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Explanation:
According to the Nernst equation the potential of the membrane for a two-compartment model of a cell for positive gradient of K⁺ ions is V = - 60 mVlogK'/K where K' = inside concentration of K⁺ ions and K = outside concentration of K⁺ ions. For a 10 fold excess of KCl in the inside compartment, K'/K = 10. So,
V = - 60 mVlogK'/K = - 60 mVlog10 = -60 mV.
For a negative gradient of Na ions is V = + 60 mVlogK'/K where K' = inside concentration of Na⁺ ions and K = outside concentration of Na⁺ ions. (Since the cell is selectively permeable to Na⁺ ions. So, Na ions to not flow out but in.)For a 10 fold excess of NaCl in the inside compartment, K'/K = 10. So,
V = + 60 mVlogK'/K = + 60 mVlog10 = +60 mV.
So, when the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Answer:A,B,D,E,F
Explanation:
Stock can be transfer depending on the organization.
The movement of stock is divide into three broad categories
Stock transfer from Plant to plant- movement of stock from a plant to another plant
Stock transfer from Company code to company code- movement from ome company code to another
Stock transfer from Storage location to storage location
Between different plants within the same storage - stock can be moved from one plant to another within the same storage this will lead to a change in quantity in both plant and it should be noted
Between storage locations within one plant- stock location can be change in a plant but it doesn't affect the quantity.
Between plants in different company code- stock can also be moved from one company code to another this requires adequate documentation when the stocked are moved.
I’m pretty sure the C molecules are carbon dioxide? And the O molecules are Oxygen? yeah.. I’m pretty sure
The answer is Llanos. Llanos or in Spanish it is called plains. These are wide grasslands stretching across northern South America and inhabiting western Venezuela and northeastern Colombia. The Llanos have a region of approximately 220,000 square miles, surrounded by the Andes Mountains to the north and west, the Guaviare River and the lower Orinoco River and the Guiana Highlands to the east, and the Amazon River basin to the south.
