Vadim26 [7]4 years ago
4 0

Answer:

The final angular speed of the carousel is 1.68 rad/s.

Explanation:

This is simply a conservation of angular momentum problem.

\vec{L}_0 = \vec{L}_1\\L_0 = I_0\omega_0 = 125*3.14 = 392.5\\L_1 = I_1\omega_1 = (mR^2 + I_0)\omega_1 = (48*1.5^2 + 125)\omega_1 = 233\omega_1

Combining the two equations yields the angular momentum of the carousel after the man climbs.

392.5 = 233\omega_1\\\omega_1 = 1.68~rad/s

Explain why an electromagnetic wave is a transverse was and not a compressional wave
arlik [135]
Electromagnetic waves are transverse because the particles that are moving are perpendicular to the wave motion while compressional (also known as longitudinal) wave particles move parallel to the wave motion

A radio wave has a frequency of 4.40 × 108 hz. what is the energy (in j) of one photon of this radiation? enter your answer in s
LiRa [457]
The energy of a single photon is given by
E=hf
where 
h=6.6 \cdot 10^{-34} Js is the Planck constant
f is the frequency of the wave (of the photon)

In our problem, the radio wave has a frequency of f=4.40 \cdot 10^8 Hz, so if we put this value into the previous formula, we can find the energy of a single photon of this electromagnetic wave:
E=hf=(6.6 \cdot 10^{-34} Js)(4.40 \cdot 10^8 Hz)=2.9 \cdot 10^{-25} J

A turtle accelerates from a stop at 3m/s/s to the South for 8s. What is the turtle’s final velocity? Show your work and include
andrey2020 [161]

He's accelerating at 3 m/s² .  That means his speed is increasing by 3 m/s every second.At the end of 8 seconds, his speed is (8 x 3 m/s)  =  24 m/s .He's been moving south for the whole 8 seconds.So at the end of that time, his velocity is                          24 m/s south .
