The answer to this item is rondo, letter A. As already mentioned in the above's definition, this has a recurring or repetitive lead them two contrasting sections. The contrasting sections are more commonly referred to as "episodes" and occasionally as "digressions" or "couplets".
Answer:
1.8 m
Explanation:
Given: Glass falls from a table, smashes 0.6 seconds later
To find: How high a table is
Formula: Vv=gt, dv=1/2gt^2, t=2d/g
Solution: A table's <em>height</em> is measured from the top of the edge down to the floor. The tables are shown both have a height of 30 inches, which is common for many tables.

- d = 4.905 (0.6²)
- d = 442.676
Hence the table is 1.8 m high
Answer:
Explanation:
90 rpm = 90 / 60 rps
= 1.5 rps
= 1.5 x 2π rad /s
angular velocity of flywheel
ω = 3π rad /s
Let I be the moment of inertia of flywheel
kinetic energy = (1/2) I ω²
(1/2) I ω² = 10⁷ J
I = 2 x 10⁷ / ω²
=2 x 10⁷ / (3π)²
= 2.2538 x 10⁵ kg m²
Let radius of wheel be R
I = 1/2 M R² , M is mass of flywheel
= 1/2 πR² x t x d x R² , t is thickness , d is density of wheel .
1/2 πR⁴ x t x d = 2.2538 x 10⁵
R⁴ = 2 x 2.2538 x 10⁵ / πt d
= 4.5076 x 10⁵ / 3.14 x .1 x 7800
= 184
R= 3.683 m .
diameter = 7.366 m .
b ) centripetal accn required
= ω² R
= 9π² x 3.683
= 326.816 m /s²

I believe this is right but double check to make sure :)
Responder:
43.84 m²
Explicación:
Dada la dimensión de una placa rectangular como:
Longitud (L) = 8.430 m
Ancho (W) = 5.201 m
El Área de una placa rectangular se puede obtener usando la fórmula:
Área = Largo × Ancho
Área = 8.430m * 5.201m
Superficie = 43.84443 m²
Área = 43.84 m²
