current passes through a filament of an incandescent bulb, thereby increasing
it temperature. When current flows, it contains electrons through the filament
to produce light. The answer is c. Typically, incandescent light bulb consists
of a glass enclosure that contains tungsten filament. The glass enclosure contains
either a vacuum or an inert gas that serves as the filament protection from
evaporating. Incandescent light bulbs contain a stem attached at to its base to
allow the electrical contacts to run through the envelope without gas or air

V=v0+at=38m/s;
v^2=v0^2+2ad=>d=(v^2-v0^2)/2a=544/4=68m
Answers:
A) 0.204 m
B) 0.285 s
Explanation:
<h2>Answer A:</h2>
This described situation is free fall, this means the initial velocity of the fly is zero, and the equation that will be used is:
(1)
Where:
is the final height of the fly
is the initial height of the fly
is the initial velocity of the fly
is the time
is the acceleration due to gravity
(2)
(3) This is the distance at which the fly would begin to beat its wings
<h2>Answer B:</h2>
In this part we will also use equation (1), but we will find the time:
(1)
Where:
is the final height of the fly
is the initial height of the fly
is the initial velocity of the fly
is the time we need to find
is the acceleration due to gravity
(4)
Isolating
:
(5)
(6) This is the time it would take for a fly to hit the bottom of the box
False. solar comes from the sun while wind energy comes from the wind. hope this helps!
Answer:
1 mm^3 = 1.0 x 10^-9 m³
Hence;
5.23 x 10^-6 kg/mm^-3 = (5.23 x 10^-6 kg)/ 1x10^-9 m³
= 5230 kg/m³
