AnnZ [28]

Answer:

Hello your question has some missing parts attached below is the complete question

answer : 4 μm

Explanation:

since the scale bar works the same way as a scale on a map , each bar will therefore represent 1 μm and the mature parent cell's is about 4 times the labeled value hence the Mature parent cell diameter will approximately be : 4 μm

Lithium is a metal with an oxidation number of 1+ and oxygen is a nonmetal with an oxidation number of 2-. Which chemical formul
Feliz [49]

The answer is Li2O.

Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides.

What is the passengers velocity on the vertical drop of the tower of terror at Disney world if the distance for the drop is 50m,
andrey2020 [161]

Assuming constant acceleration due to gravity of a=9.8\,\dfrac{\mathrm m}{\mathrm s^2}, and assuming the passengers start at rest, so that v_0=0\,\dfrac{\mathrm m}{\mathrm s}, we have

v=v_0+at\implies v=\left(9.8\,\dfrac{\mathrm m}{\mathrm s^2}\right)(5.5\,\mathrm s)=53.9\,\dfrac{\mathrm m}{\mathrm s}

or 54 m/s if taking significant digits into account.

8. How many calories of heat energy (Q) would be released as a 2,500 g iron (Fe) frying pan at 190˚C cools to 25˚C?
Sedaia [141]

Answer:

Q=197505J

Explanation:

From the question we are told that:

Mass m=2500g=2.5kg

Initial heat of pan i_h=190 \tetxtdegree

Final heat of pan f_h=25˚C \tetxtdegree

 

Generally the equation for Heat energy released is mathematically given by

 Q=mC \triangle T\\\\Q=2.5*462 *(190-26)\\\\Q=1155 *(190-26)\\\\Q=1155 *(171)\\

 Q=197505J
