The ball rolled for 13.2 s
<h3>Further explanation</h3>
Speed is scalar and no direction
![\tt avg~speed=\dfrac{total~distance}{elapsed~time}=\dfrac{\Delta x}{\Delta t}](https://tex.z-dn.net/?f=%5Ctt%20avg~speed%3D%5Cdfrac%7Btotal~distance%7D%7Belapsed~time%7D%3D%5Cdfrac%7B%5CDelta%20x%7D%7B%5CDelta%20t%7D)
A bowling ball rolls 33 m, with average speed = 2.5 m/s
So elapsed time :
![\tt t=\dfrac{33~m}{2.5`m/s}=13.2~s](https://tex.z-dn.net/?f=%5Ctt%20t%3D%5Cdfrac%7B33~m%7D%7B2.5%60m%2Fs%7D%3D13.2~s)
Answer:
opposite the sun. between the Earth and the sun. rising perpendicular to the sun.
Explanation:
<span>An example of a high energy electromagnetic wave is "X-Ray"
When car runs, it's chemical energy (gasoline) converts into mechanical energy
Temperature is the measure of hotness or coldness of the body, so when heat expose to a substance, it's degree of hotness increases & it's temperature increases
Hope this helps!

Answer:
a. 1.027 x 10^7 m/s b. 3600 V c. 0 V and d. 1.08 MeV
Explanation:
a. KE =1/2 (MV^2) where the M is mass of electron
b. E = V/d
c. V= 0 V (momentarily the pd changes to zero)
d KE= 300*3600 v = 1.08 MeV
Answer:
first blank is chemical second blank is kinetic energy
