Question

Определить силу тяжести и вес , действующие на тело массой 4,5т

Answer 1

Ответ: 45кН

Объяснение:

Дано:

m=4,5т=4500кг

------------------------

F-?; Р-?

Сила тяжести — это сила, с которой Земля действует на тело, а вес — сила, с которой тело действует на опору. Это значит, что у них будут разные точки приложения: у силы тяжести к центру масс тела, а у веса — к опоре. По величине сила тяжести равна весу тела:

F=P=mg=4500*10=45000Н=45кН

Answer 2

Determining the Force of Gravity and Weight on an Object with a Mass of 4.5t

To determine the force of gravity and weight acting on an object with a mass of 4.5t, we can use the following formulas and principles:

1. Force of Gravity: - The force of gravity acting on an object can be calculated using the formula: F = m * g, where: - F is the force of gravity, - m is the mass of the object, and - g is the acceleration due to gravity.

2. Weight: - The weight of an object can be calculated using the formula: W = m * g, where: - W is the weight of the object, - m is the mass of the object, and - g is the acceleration due to gravity.

Now, let's calculate the force of gravity and weight for the given mass of 4.5t.

Calculations

1. Force of Gravity: - Using the formula F = m * g, where m = 4.5t and g is the acceleration due to gravity.

2. Weight: - Using the formula W = m * g, where m = 4.5t and g is the acceleration due to gravity.

Results

1. Force of Gravity: - The force of gravity acting on the object with a mass of 4.5t is calculated to be F = 44.1 kN.

2. Weight: - The weight of the object with a mass of 4.5t is calculated to be W = 44.1 kN.

Therefore, the force of gravity and the weight acting on the object with a mass of 4.5t are both approximately 44.1 kN.
