Refer to the diagram shown below.
The following discussion assumes a simplistic analysis that ignores air resistance and variations in the terrain that the missile travels over.
Let the launch velocity be V₀ at an angle of θ relative to the horizontal.
The horizontal component of velocity is V₀ cosθ.
If the time of flight is
, then
where r = the range of the missile.
Also, the time, t, when the missile is at ground level is given by
where g = acceleration due to gravity.
t = 0 corresponds to when the missile is launched. Therefore
Therefore
Typically, θ=45° to achieve maximum range, so that
This analysis is more applicable to a scud missile rather than a powered, guided missile.
Answer:
Usually, θ=45°
Yes I'm pretty sure you can
Answer:
Ampere
Explanation:
The ampere is the unit of measurement in the international system. Its equal to a coulomb/second. It can be describe as the rate of charges flowing throught a conductor
Answer: The correct answer is option(d).
Explanation:
The light given by the combination of the all the seven colors is white color.
Generally white light splits into the band of seven colors when passed through the prism which is known as spectrum.
When the Anna shines a beam of light that includes all the wavelengths of visible light onto the wall she will observe the white light on the wall of the darken room.
Hence, the correct option is (d).
