( 1.05 x 10¹⁵ km ) x ( 1 LY / 9.5 x 10¹² km ) x ( 1 psc / 3.262 LY ) =
(1.05) / (9.5 x 3.262) x (km · LY · psc) / (km · LY) x (10¹⁵⁻¹²) =
(0.03388) x (psc) x (10³) =
33.88 parsecs
Answer:
D) 8.0 s.
Explanation:
(The following exercise is written in Spanish. Hence, explanations will be held in such language.)
La energía requerida para elevar el ascensor es el cambio en la energía potencial gravitacional, cuya magnitud es:
Ahora, la potencia media es el resultado anterior dividido por el tiempo. Se despeja el tiempo de la ecuación:
La opción más aproximada es D.
In a science experiment, the dependent variable is the thing that will change based on what else is happening in the experiment. The independent variable is the thing that stays the same every time.
A shuttle stays in orbit because of the gravitational pull of earth its just like how the moon is able to orbit the earth
<span>Young modulus E = stress/strain where E is the elastic modulus. We seek to calculate the the strain.
But we would have to get the stress first. Tensile stress = Force/Area. Force = 20100N. And the Area = 9.54* 13.9 = 132.606Nm^2.
Strain = stress/E.where E = 79. Hence we have 132.606/79 = 1.67</span>
