Question

1.Визначте масу тiла, якщо на поверхнi Мiсяця на нього дiє сила тяжiння 8,64Н.Яка сила тяжiння дiятиме на це тiло на поверхнi Землi?Прискорення вiльного падiння на Мiсяцi-1,7м/с2.(33.1) ​

Answer 1

Ответ: 50,8Н

Объяснение:

Дано:

Р1=8,64Н

g1=1,7м/с²

g2=10м/с²

-----------

Р2-?

P1=mg1

m=P1/g1=8,64/1,7=5,08кг

Р2=mg2=5,08*10=50,5Н

Answer 2

To determine the mass of an object, we can use the formula:

Weight = mass x acceleration due to gravity

Given that the weight of the object on the Moon is 8.64 N and the acceleration due to gravity on the Moon is 1.7 m/s^2, we can rearrange the formula to solve for mass:

mass = weight / acceleration due to gravity

Substituting the given values, we have:

mass = 8.64 N / 1.7 m/s^2

Calculating this, we find that the mass of the object on the Moon is approximately 5.08 kg.

Now, let's determine the weight of the same object on Earth. The acceleration due to gravity on Earth is approximately 9.8 m/s^2. Using the same formula:

Weight = mass x acceleration due to gravity

Substituting the mass we just calculated (5.08 kg) and the acceleration due to gravity on Earth (9.8 m/s^2), we have:

Weight = 5.08 kg x 9.8 m/s^2

Calculating this, we find that the weight of the object on Earth is approximately 49.784 N.

Therefore, the force of gravity acting on the object on the surface of the Earth is approximately 49.784 N.
