Answer:
Mass = 386 kg
Explanation:
<u><em>Density = Mass / Volume</em></u>
Mass = Density × Volume
Where D = 19300 kg/m³ , V = 0.02 m³
<em>Putting the given in the above formula</em>
Mass = 19300 × 0.02
Mass = 386 kg
Answer:
Angular speed ω=3771.4 rad/min
Revolution=5921 rpm
Explanation:
Given data
To find
Angular speed ω
Revolution per minute N
Solution
First we need to convert the speed of truck to inches per mile
as
1 mile=63360 inches
1 hour=60 minutes
so
Now to solve for angular speed ω by substituting the speed v and radius r in below equation
To solve for N(revolutions per minute) by substituting the angular speed ω in the following equation
Can't

Answer:
Ultra violet rays and infrared rays
Explanation:
The electromagnetic radiation in the order of increasing wavelength is given as
Gamma rays
X rays
Ultra violet rays
Visible radiation
Infrared rays
Microwaves
radiowaves
So, the radiations having wavelength more than the visible radiation are infrared radiations and the radiations which having the wavelength less then the visible radiation is Ultraviolet rays.
So, we observe ultra violet radiations and infrared radiations.
