Question

На долоні лежить яблуко масою 200 г. (1б) А. Якщо долоня перебуває в спокої, вага яблука менша за 3 Н. Б. Якщо долоню рухати з прискоренням, напрямленим угору, то сила тяжіння, що діє на яблуко, збільшиться. В. Якщо долоню різко висмикнути, то вага яблука дорівнюватиме силі тяжіння. Г. Якщо долоню рухати з прискоренням, напрямленим униз, то сила тяжіння, що діє на яблуко, зменшиться.​

Объяснение:

А. Якщо долоня перебуває в спокої, вага яблука менша за 3 Н.

Б. Якщо долоню рухати з прискоренням, напрямленим угору, то сила тяжіння, що діє на яблуко, збільшиться.

Г. Якщо долоню рухати з прискоренням, напрямленим униз, то сила тяжіння, що діє на яблуко, зменшиться.​

Answer 2

The weight of an apple on the palm of a hand

The weight of an apple on the palm of a hand can be affected by various factors, such as the position of the hand and the presence of external forces. Let's examine each statement and determine its accuracy based on the search results.

A. If the palm is at rest, the weight of the apple is less by 3 N.

There is no information available in the search results to support or refute this statement.

B. If the palm is moved upwards with acceleration, the gravitational force acting on the apple will increase.

When the palm is moved upwards with acceleration, the gravitational force acting on the apple remains constant. The weight of the apple is determined by the gravitational force, which is approximately 9.8 m/s^2 on Earth. Therefore, the statement is incorrect.

C. If the palm is jerked suddenly, the weight of the apple will be equal to the gravitational force.

When the palm is jerked suddenly, the weight of the apple remains the same. The weight of an object is the force exerted on it due to gravity. It is independent of the motion or acceleration of the object. Therefore, the statement is incorrect.

D. If the palm is moved downwards with acceleration, the gravitational force acting on the apple will decrease.

When the palm is moved downwards with acceleration, the gravitational force acting on the apple remains constant. The weight of the apple is determined by the gravitational force, which is approximately 9.8 m/s^2 on Earth. Therefore, the statement is incorrect.

In summary, statements B, C, and D are incorrect based on the search results. Statement A does not have enough information available to determine its accuracy.
