Explanation:
It’s atoms thank me later (give me brailiest)
same, stapler, gravity, motion, acceleration
Answer:
A) It will move at a different speed (i.e slower)
B) A vacuum
Explanation:
For A), Light moves at a different speed as it starts to interact more with the particles in said medium (in this case, water) than the earlier medium.
For B), Light propagates using its own particle, i.e the photon whereas sound is more of a transmission of energy from the particles it originates from. In a vacuum, there are no particles to transfer energy to, that is why light can travel in a vacuum and sound cannot
Answer:
1) El diámetro es de aproximadamente 913,987 cm.
2) La fuerza del cilindro es 5576850 kgf
Explanation:
1) Los parámetros dados son;
El volumen del aire = 13,122 litros = 13122000 cm³
La presión de trabajo = 8.5 kgf / cm²
La longitud del cilindro = 20 cm.
Por lo tanto, tenemos;
El área de la base del cilindro = π · r² = 13122000 cm³ / (20 cm) = 656100 cm²
r = √ (656100 / π) ≈ 456,994 cm
El diámetro = 2 × r ≈ 2 × 456.994 ≈ 913.987 cm
El diámetro ≈ 913,987 cm
2) La fuerza del cilindro = El área de la base del cilindro × La presión de trabajo
∴ La fuerza del cilindro = 656100 cm² × 8.5 kgf / cm² = 5576850 kgf
La fuerza del cilindro = 5576850 kgf
