a) many people think that no energy or matter exists outside the universe.
An isolated system is defined as a system that does not interact with its surroundings. This is the reason that its total energy and mass remains constant. Moreover, t<span>otal</span><span> momentum in a system is conserved for collisions occurring in </span><span>isolated systems.</span>
Answer:
Radius of the salami = 9.9 cm
Explanation:
The formula for calculating the radius is given below:
a = v^2/r
where a represents acceleration
v represents velocity
r represents radius
As hungry mouse ran around the salami's circumference with a tangential speed of 0.17 m/s so that means velocity = 0.17 m/s.
The centripetal acceleration of the mouse = 0.29 m/s^2
putting these values in the above formula, we get
0.29 = 0.17^2 / r
After rearranging, we get,
r = 0.17^2 / 0.29
r = 0.099 m
r = 9.9 cm
so the radius of the salami = 9.9 cm

Answer:
C) Plastic
Explanation:
Copper, silver, and gold all conduct electricity. Therefore, the material that would provide the most resistance for electricity would be plastic.
