Can you please give me brainiest.
Responder:
- Volumen del bloque = 60cm³
- Densidad = 5g / cm³
Explicación:
Dada la dimensión del bloque
AB = 4 cm, BC = 2.5 cm y BF = 6 cm
Volumen del bloque = Largo × Ancho × Alto
Volumen del bloque = AB × BC × BF
Volumen del bloque = 4 × 2.5 × 6
Volumen del bloque = 60cm³
Dada la masa del bloque = 300 gramos
Densidad = Masa / Volumen
Densidad = 300g / 60cm³
Densidad = 5g / cm³
Algunos materiales que tienen una densidad de 5g / cm³ o cercanos son radio, germanio y europio con densidades de 5g / cm³, 5.3g / cm³ y 5.24g / cm³ respectivamente.
Answer:
58.9 N
Explanation:
The wood is buoyed up by the mass of the water is displaces
wood volume = .030 m^3 = 30 000 cm^3
mass of water displaced = 30 000 g = 30 kg
wood mass = 800 kg/m^3 * .030 m^3 = 24 kg
so tension in string = mg = ( 30 kg - 24 kg) * 9.81 m/s^2 = 58.9 N
