What produces the distinctive flame color of different substances when they are ignited?
shepuryov [24]

Answer:

Electrons in different metals

Explanation:

When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy.  The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.

A fighter jet is launched from an aircraft carrier with the aid of its own engines and a steam-powered catapult. The thrust of i
kirza4 [7]

Answer:

2.5 x 10⁷ J

Explanation:

F = thrust of the engine = 2.3 x 10⁵ N

d = distance traveled = 87  m

Work done by the engine is given as

W = F d =  (2.3 x 10⁵) (87) = 200.1 x 10⁵ J

W' = Net work done

W'' = work done by catapult

KE₀ = initial kinetic energy = 0 J

KE = final kinetic energy = 4.5 x 10⁷ J

Net work done is given as

W' = KE - KE₀

W' = 4.5 x 10⁷ J

We know that

W' = W + W''

4.5 x 10⁷ = 2.001 x 10⁷ + W''

W'' = 2.5 x 10⁷ J

A cylinder with rotational inertia I₁ = 2.4 kg · m² rotates clockwise about a vertical axis through its center with angular spee
miv72 [106K]

Answers :

Explanation:

Given that.

First cylinder data

Inertial I₁ = 2.4 kgm²

angular speed ω₁ = 5.8 rad/s.

Second cylinder data

inertia I₂ = 1.3 kgm²

angular speed ω₂ = 7.0 rad/s.

If the cylinders couple so they have the same rotational axis, what is the angular speed of the combination (in rad/s)?

So, the cylinder couple and move together with the same angular speed

Then, using conservation of angular momentum

L(final) = L(initial)

(I₁ + I₂) • ω = I₁•ω₁ + I₂ω₂

(2.4+1.3)•ω = 2.4 × 5.8 + 1.3 × 7

3.7•ω = 23.02

ω = 23.02 / 3.7

ω = 6.22 rad/s

The combine angular speed of the cylinder is 6.22 rad/s
