Question

Step gently onto a bathroom scale, read the dial, and then jump from a chair onto the same scale.

Answer 1

Answer:

1)The second is correct. The scale shows a higher value initially and after a short time it shows the same value of rising gently

2) The correct answer is the first does not change

Explanation:

1) Let's look for the solution of the problem before seeing the statements given

We use Newton's second law

     Fb - w = ma

     Fb = ma + mg

     Fb = m (a + g)

When you go up smoothly, the acceleration a is zero, but when you go up sharply it is different from zero, after a short time it reaches zero and the strength of the bastecía is the same as at the beginning.

Affirmations

The second is correct. The scale shows a higher value initially and after a short time it shows the same value of rising gently

2) changes the value of g

The value of the acceleration of gravity depends on the mass and radius of the Earth only, not the conditions or movements of the person. The value of g does not change

The correct answer is the first does not change
