Is it possible to estimate densities of liquids in a container by holding them in your hand? Explain.

Answers

Answer 1
Answer: No, Because if u do that it wouldn't be the right amount of density. So therefore your density will be wrong.

Give two reasons why we feel earths gravity more strongly than the moons gravity

Answers

Answer:

Explanation:

The force of gravity is the physical force exerted by the mass of a planet on the objects that are within its gravitational field. In other words, this law establishes that bodies, by simply having mass, experience a force of attraction to other bodies with mass.

The force of gravity depends on the mass of each object. The force with which two objects are attracted is proportional to their mass and decreases rapidly with distance:

F=G*(m1*m2)/(r^(2) )

where G is the universal gravitation constant, whose value is

G=6.673*10⁻¹¹ (N*m^(2) )/(kg^(2) )

This expression indicates that the gravitational force that a point mass M exerts on another point mass m that is at a distance r from the previous one is directly proportional to the product of the masses and inversely proportional to the square of the distances that separates them.

Given the above, it is possible to say that two reasons why we feel the Earth's gravity more strongly than the moon's gravity are:

  • Being the mass of a person the same, the mass of the Earth is greater than the mass of the Moon
  • The distance r between the Earth and us is much closer than the distance r between the Moon and us (remember that the Earth exerts its force of gravity from the center)

This causes the force exerted by the Earth on us to be much greater.

1).  The Earth has about 80 times as much mass as the Moon has.

2). The Earth is closer to many of us than the Moon is.

John and Daniel are playing tug-of-war together. John is exerting 10 N of force. Daniel is exerting 12 N of force. What is their net force

Answers

We assume that they're pulling in opposite directions ...
that's how this game works.

Daniel completely cancels out John's whole 10N, and he
still has 2N left over.

The NET force on the rope is 2N in the direction of Daniel.
So the rope accelerates in Daniel's direction.

an unbalanced force moving everyone in Daniel and Maria's direction
