Please show work. A 150 kg steel rod in a building under construction supports a load of 6050 kg. During the day, the rod’s temperature increases from 22°C to 47°C. This temperature increase causes the rod to thermally expand and raise the load 5.5 mm.

a. Find the energy transferred as heat to or from the rod. (Hint: Assume the specific heat capacity of steel is the same as for iron.)

b. Find the work done in this process. Is work done on or by the rod?

c. How great is the change in the rod’s internal energy? Does the rod’s internal energy increase or decrease?

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
