In 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.

97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.) m/s2 Compare your answer with the free-fall acceleration, 9.80 m/s2 (i.e. how many times stronger than gravity is this force?). g

Answer:

The unrealistically large acceleration experienced by the space travelers during their launch is 2.7 x 10⁵ m/s².

How many times stronger than gravity is this force? 2.79 x 10⁴ g.

Explanation:

given information:

s = 220 m

final speed, vf = 10.97 km/s = 10970 m/s

g = 9.8 m/s²

he unrealistically large acceleration experienced by the space travelers during their launch

vf² = v₀²+2as, v₀ = 0

vf² = 2as

a =vf²/2s

  = (10970)²/(2x220)

  = 2.7 x 10⁵ m/s²

Compare your answer with the free-fall acceleration

a/g = 2.7 x 10⁵/9.8

a/g = 2.79 x 10⁴

a = 2.79 x 10⁴ g

Which of the following most easily transfers charge?
raketka [301]
A. Conductors. Because in conductors, gap between valence band and conduction band is negligible. Due to this electrons from valence band moves spontaneously to conduction band and on small heating the conductors.

Una pelota de voleibol de 0.45 kg es impactada (golpeada) por una fuerza de 80 N. ¿ Cuál es la aceleración que experimenta la pe
KIM [24]

Answer:

a = 177.77 [m/s^2]

Explanation:

Este es un problema relacionado con la segunda ley de Newton. La cual nos dice que la sumatoria de fuerzas aplicada sobre un cuerpo debe ser igual al producto de la masa por la aceleración.

De esta manera tenemos:

F = m*a

F = fuerza = 80 [N]

m = masa = 0.45 [kg]

80 = 0.45 * a

a = 80 / 0.45

a = 177.77 [m/s^2]

The complete process for learning through repetition is to read, write, say, rest and revisit the information. T or F.
Dima020 [189]

Answer: The given statement is True.

Learning means change or modification in the behavior of an individual that is obtained by getting new information, knowledge, skills or different experiences throughout the life.

There can be different learning styles like visual ( using pictures and images), verbal ( like repetition or rehearsal), social ( in groups), logical ( using reasoning) that could be adopted by different individuals.

The information can be memorized through repetition of the information by continuously reading, writing, speaking, and revisiting it.
