Answer:
<em>The hang time is 2.04 seconds</em>
Explanation:
<u>2-D Motion
</u>
It referred to as a situation where an object is launched in such a way it describes a curve, reaches a top height and then returns to ground level after traveling a certain distance x away from the launch point.
Let be the launching speed forming an angle with the horizontal reference. The hang time (time the object remains in the air) is given by
Since
Then
We'll use the given values
The hang time is 2.04 seconds

Answer:
497.143 nm.
Explanation:
Diffraction grating experiment is actually done by passing light through diffraction glasses, the passage of the light causes some patterns which can be seen on the screen. This is because light is a wave and it can spread.
The solution to the question is through the use of the formula in the equation (1) below;
Sin θ = m × λ. ---------------------------------(1).
Where m takes values from 0, 1, 2, ...(that is the diffraction grating principal maxima).
Also, m × λ = dc/ B -------------------------------------------(2).
We are to find the second wavelength, therefore;
λ2 =( m1/c1) × (c2/m2) × λ1 ------------------------(3).
Where c1 and c2 are the order maximum and m = order numbers. Hence;
λ2 = (1/ .350) × (.870/3) × 600 = 497.143 nm.

Answer:
The Reynolds number determines what type of regime is laminar or turbulent in a flow pattern.
Explanation:
The Reynolds number determines what type of regime is laminar or turbulent in a flow pattern.
In the laminar regime R_D <2300 the flow is ordered and has an envelope predicted by the expressions
In the turbulent regime R_D> 2900 the flow has vortices and is extremely irregular
in the intermediate values it is in a transition regime
