Action at a distance, such as is the case for gravity, was once thought to be illogical and therefore untrue. What is the ultima

te determinant of the truth in science, and why was this action at a distance ultimately accepted?

Answer:

The ultimate determinant of truth in science is the execution of scientific experiments that prove or discredit a certain scientific statement. It was through scientific experiments that gravity was accepted scientifically.

Explanation:

Gravity was first observed by Isaac Newton, who quickly created theories and calculations to prove it and show that it exists, in addition to showing the influences it has on life and on the planet.

However its existence was discredited by several people, including men of science. Therefore, it was necessary to search for facts, calculations and evidence of its existence, so that it could be accepted and studied more and more deeply. The result of this, was the elaboration of diverse experiences that submitted the gravity to the most different tests until its existence was impossible to be denied.

(20 points) You are at the center of a boat and have been rowing the boat for a long time. You weigh only 80 kg and your 120 kg
valina [46]

Answer:

Explanation:

From the given information:

Let the first weight be m_ 1 = 80 kg

The weight of the buddy be m_2 = 120 kg

The weight of  Bubba be m_3 = 60 kg

Also, since you and Budda are a distance of 4m to each other, then the length to which both meet buddy will be:

x_1 = x_3 = \dfrac{4}{2} \\ \\ = 2

The length of the boat be x_2 = 4 m

∴

We can find the center of mass of the system by using the formula:

X_{CM} = \dfrac{m_1x_1+m_2x_2+m_3x_3}{m_1+m_2+m_3} \\ \\ X_{CM} = \dfrac{(80 \times 2)+(120\times4)+(60\times2)}{80+120+60} \\ \\ X_{CM} = \dfrac{160+480+120}{260} \\ \\ \mathbf{X_{CM} = 2.923}

Which of the following statements about Gaussʹs law are correct? (There may be more than one correct choice.) Question 3 options
irina1246 [14]

Answer:

If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface.

Explanation:

Option A is incorrect because, given this case, it is easier to calculate the field.

Option B is incorrect because, in a situation where the surface is placed inside a uniform field, option B is violated

Option C is also incorrect because it is possible to be a field from outside charges, but there will be an absence of net flux through the surface from these.

Hence, option D is the correct answer. "If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface."
