Answer:
3.8 kg
Explanation:
The torque, <em>τ</em>, due to the force, <em>F</em>, is given by
where <em>r</em> is the radius.
This torque is also given by
where <em>I</em> and <em>α</em> are respectively the moment of inertia and the angular acceleration.
For a solid disk, its moment of inertia for an axis though its centre and perpendicular to its face is given by
where <em>m</em> is its mass and <em>r</em> is its radius.
Hence, we have
<u>Answer</u>:
Yes, there are differences between supersonic planes and concorde planes
<u>Explanation</u>:
The supersonic planes moves faster than the speed of sound. But these flights are banned because it is economically non-starter. It has more loud sound equivalent to the explosion. The banned was elevated in 2003, due to new aviation law. The concords travel twice the speed of sound. This planes holds the record for the fastest planes but seen to be fleet long back i.e. in 2003. These were banned when a fatal crash had been reported. And now are only found in the museums.
Psychological disorder is a kind of disease, related to brain functioning, they are very different, but can't be distinguished at high level so they are not extremely different
In short, Your Answer would be: "False"
Hope this helps!
Answer:
1. The speed of infrared radiation is greater than radio wave radiation
2. The wavelength of infrared radiation is less than the radio wave radiation
Explanation:
Given:
The radio wave radiation N₁ is 3x10⁵ to 3x10⁷ Hz and the infrared radiation N₂ is 3x10¹¹ to 3x10¹⁴ Hz. The speed is:
1. The speed of infrared radiation is greater than radio wave radiation
2. The wavelength is:
λ = C/N
where more C, less λ
Then, the wavelength of infrared radiation is less than the radio wave radiation
