With arms outstretched,
Moment of inertia is I = 5.0 kg-m².
Rotational speed is ω = (3 rev/s)*(2π rad/rev) = 6π rad/s
The torque required is
T = Iω = (5.0 kg-m²)*(6π rad/s) = 30π
Assume that the same torque drives the rotational motion at a moment of inertia of 2.0 kg-m².
If u = new rotational speed (rad/s), then
T = 2u = 30π
u = 15π rad/s
= (15π rad/s)*(1 rev/2π rad)
= 7.5 rev/s
Answer: 7.5 revolutions per second.
Answer:
C. Access to the Aegean Sea was important for trade and transportation.
Explanation:
"Macedonia" <em>(ancient) </em>was a small kingdom located in the north of Greece. Its region is located near communication routes, such as the <u>Danube River</u> and the<u> Aegean Sea.</u>
In the past, it had access to the Aegean Sea which facilitated trade and transportation between people coming from different areas. This is also the reason why many of the ports are currently located along the Greek coasts of the Aegean Sea.
The Greek region of Macedonia is called <em>"Aegean Macedonia."</em>
So, this explains the answer.
Answer:
The removal of heat energy slows the speed of particles
Explanation:
When you add heat to a substance, the heat energy gets transferred to kinetic energy, and the molecules began to move a greater distance at a greater speed. When you remove heat, the opposite happens.
At a given moment in time, the instantaneous speed can be thought of as the magnitude of instantaneous velocity.
Instantaneous speed is the magnitude of the instantaneous velocity, the instantaneous velocity has direction but the instantaneous speed does not have any direction. Hence, the instantaneous speed has the same value as that of the magnitude of the instantaneous velocity. It doesn't have any direction.
