Answer:

0.13

Step-by-step explanation:

change of heat: 35-25 =10 degrees

mass=20

energy=26

c =??

c = Q / (m * ΔT)

=26/20*10= 26/200=0.13 J/g*k

A meteor crater is 3400 feet in diameter. Approximate the distance around the crater. Use 3.14 for piπ.

pishuonlain [190]

$\bf \textit{distance around the crater, or Circumference of a circle}
\\\\\\
C=2\pi r\qquad 
\begin{cases}
C= circumference\\
r=radius=\frac{diameter}{2}\\
--------------\\
diameter=3400\\
r=\frac{3400}{2}
\end{cases}
\\\\\\
C=2\pi \cdot \frac{3400}{2}$
