Question

Какое давление оказывает клей на железную скрепку, находящуюся на дне банки? Плотность клея 1500 кг\ м³.Высота банки 8 см

Answer 1

Дано:
ρ = 1500 кг/м³
h = 8 см
g = 10 Н/кг
p - ?
Решение
8 см = 0,08 м
p = ρgh
p = 1500 * 10 * 0,08 = 1200 (Па)
Ответ: p = 1200 Па

Answer 2

Дано   p=1500 кг/м3     h=0,08 м       P - ?
 
P=p*g*h=1500*10*0,08=1200 Па

Answer 3

Calculating Pressure Exerted by Glue on the Iron Staple

To calculate the pressure exerted by the glue on the iron staple at the bottom of the jar, we can use the formula for pressure:

Pressure (P) = Density (ρ) × gravitational acceleration (g) × height (h)

Given: - Density of the glue (ρ) = 1500 kg/m³ - Height of the jar (h) = 8 cm = 0.08 m - Gravitational acceleration (g) = 9.81 m/s² (standard value)

Calculation

Using the given values, we can calculate the pressure exerted by the glue on the iron staple:

Pressure (P) = 1500 kg/m³ × 9.81 m/s² × 0.08 m

Pressure (P) ≈ 1178.4 pascals

So, the pressure exerted by the glue on the iron staple at the bottom of the jar is approximately 1178.4 pascals.
