My science teacher said that there is no equivalent unit to a newton
This means it doesn't change its velocity and it doesn't have momentum. 3. Examples of Newton's 1st Law If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice. It will also stop if it hits something, like a player's stick or a goalpost.
The answer is: To have easy access to a coolant for the reactor.
Hope this helps!:)

This is what I found online: "<span>For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That’s about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz. While 20 to 20,000Hz forms the absolute borders of the human hearing range, </span>our hearing is most sensitive in the 2000 - 5000 Hz frequency range<span>." So i'm guessing it's 100,00 since none of those are lower than 20

Answer:
Fc = 1.7x10^-4 N
Explanation:
Convert everything to proper units:
m = 25mg = 2.5x10^-5 kg
r = 17.6cm = 0.176m
v = 110cm/s = 1.1m/s
the formula for centripetal force is Fc = mv^2 / r
Plug everything and solve for Fc;
fc = (2.5x10^-5)(1.1^2) / 0.176
Fc = 1.7x10^-4 N
