Answer:

Explanation:
First of all let's define the specific molar heat capacity.
(1)
Where:
Q is the released heat by the system
n is the number of moles
ΔT is the difference of temperature of the system
Now, we can find n with the molar mass (M) the mass of the compound (m).
Using (1) we have:

So in a fluorescent light bulb the mercury atoms release the UV light. This UV light is absorbed by the phosphorous powder coating inside and this releases the visible light.
So your answer is phosphorous powder.
Answer:
(a)
(b) I =428 
(c)
Explanation:
GIVEN
mass = 18.2 kg
radial arm length = 3.81 m
velocity = 49.8 m/s
mass of arm = 22.6 kg
we know using relation between linear velocity and angular velocity


for angular acceleration, use the following equation.

since 
here for one circle is 2 π radians. therefore for one quarter of a circle is π/2 radians
so for one quarter 

on solving

(b)
For the catapult,
moment of inertia


For the ball,



so total moment of inertia = 428 
(c)


The amplitude is changed.
