So the equation for angular velocity is
Omega = 2(3.14)/T
Where T is the total period in which the cylinder completes one revolution.
In order to find T, the tangential velocity is
V = 2(3.14)r/T
When calculated, I got V = 3.14
When you enter that into the angular velocity equation, you should get 2m/s
A- hypothesis
You usually write hypothesis in science it’s something that can usually be tested.
B- prediction
Made before you do an science experiment, they’re usually like what you think could happen or will happen.
C- theory
Theses aren’t used with scientific evidence, they’re usually things that people believe happened. Example: Some believe Big Foot is real. But no one will ever know because its a theory
D- is already been eliminated, not all are right.
Answer is A
Hope this helped :)
Answer:
It is B
it is called a jumper cable because it jumps the power from one car to the other
