A student made an Arrhenius graph of Ln(k1/k2) versus 1/T (K-1). However she erroneously plotted 1/T on the Y axis instead of plotting 1/T on the X axis. She displayed the linear trendline to her graph in Excel. The equation of the trendline was Y = -0.000084*X - 0.047. What was the value of the slope had she plotted the data correctly?
DEMONSTRATE:
As of Jan 18 2021, the 7-day average new COVID case number
for Oregon was 1035. On October 17 2020, the comparable
value was 342.
a. What was the relative change?
One-Step Calculation (Don't forget grouping):
1035 – 342

342
Answer:
b. Pick all of the following that are true.
The number of new cases has increased by
about 2% since October.
The number of new cases has increased by
about 3% since October.
O The number of new cases has about tripled in 3
months.
The number of new cases is about 300% more
than it was in October.
The number of new cases is about 200% more
than it was in October.
The number of new cases has about doubled in
3 months
The number of new cases is about 33% more
than October.

- As we discuss in class, the radius of the Earth is approximately 6370 km. Theradius of the Sun, on the other hand, is approximately 700,000 km. The Sun is located,on average, one astronomical unit (1 au) from the Earth. Imagine that you stand near Mansueto Library, at the corner of 57th and Ellis.Mansueto’s dome is 35 feet (10.7 meters) high. Let’s imagine we put a model of theSun inside the dome, such that it just fits — that is, the model Sun’s diameter is 35 feet The nearest star to the Solar System outside of the Sun is Proxima Centauri,which is approximately 4.2 light years away.
