Answer:
ω₂ = 13.09 rad/s
Explanation:
given,
small disk rotating speed = 500 rpm
radius of small disk = R
radius of larger disk = 2 R
rotational speed of larger disk = ?
using the law of conservation of angular momentum, we get
I₁ ω₁ = I₂ ω₂
moment of inertia for solid disk
now,
ω₂ = 125 rpm
and
ω₂ = 13.09 rad/s
the rotational speed of larger disc is equal to ω₂ = 13.09 rad/s
I think it’s c sorry if wrong
<h2>Answer: in a gaseous state
</h2>
The average kinetic energy of the water molecules is greater in its gaseous state (in the form of water steam).
This is because in the gaseous state the water molecules are well separated from each other and can move freely in all the available space they have; because there are no cohesion forces that bond them.
In contrast to the liquid and solid state, in which the molecules have less movement.
Explanation:
A wave having a frequency of 200 Hz means that 200 such waves pass through a point per second.
