Higher frequency,higher energy,shorter wavelength
Position, speed, direction, and acceleration
Answer:
17.71 kgm²s⁻¹
Explanation:
<em>Angular momentum </em>is the rotational momentum , which is quite similar to linear momentum.main difference is that here we consider a rotational motion.
*The total angular momentum of a closed system remains constant.
by definition ,
angular momentum = moment of inertia (I) × angular velocity (ω)
where
<em>ω = 2π × frequency (f)</em> = 2π × 6
<em>angular momentum = 0.47 × 12π = 17.71 kgm²s⁻¹</em>
This one is complicated. Not hard, but several steps. The two 5-ohm resistors in series have a total resistance of 10 ohms. 1.6 A through 10 ohms means the battery is (1.6 x 10)=16 volts. Then ... 16 volts produces 2A of current through (16/2)=8 ohms of resistance. If 3 identical resistors in parallel look like like 8 ohms, then each one is (8 x 3)= 24 ohms. That's D.
<span>We are using the formula: v = rω
Please consider that they have the same tangential velocity at their edges.
Therefore we can equate: r1 ω1 = r2 ω2
And re-arrange: ω1 / ω2 = r2 / r1</span>
