The answer is Gravity

There's always a gravity between any 2 objects in this universe. between you and your computer, between you and the floor, between your chair and your table, etc.

We just dont feel it because we live in earth which negates all of those gravities with its own.

What does the negative sign in F = –kx mean?
VashaNatasha [74]

It says that the force of a spring is always opposite to the direction in which you stretch it or compress it. (the direction of 'x')

In other words, a spring that's disturbed always tries to put itself back to it's normal length, where x would be zero.

What 2 kinds of substances does convection occur ?
ch4aika [34]

Liquids and Gases

Explanation:

Convection is a form of heat transfer that is predominant in liquids and gaseous substances. This form of heat transfer is driven by density differences between gases and liquids.

  • Convection involves the actual movement of the particles of a medium.
  • Boiling of food is clinical example of convection in liquids. Hot part of the food in contact with the heat source becomes less dense and more buoyant. They rise to the top of the medium and are replace by the denser and colder part of the food.
  • Land and sea breeze is an example of convection in gases. The land warms the air around it during the day. It is hotter and less dense. The air mass moves to replace the ones on the sea where the air is relatively cold due to high specific heat capacity of water.
  • The reverse process occurs at night.

A wire has a length of 0.50 m and measures about 0.50 mm in its cross-sectional radius. At normal temperature, what is its resis
miv72 [106K]

Answer:

Explanation:

For resistance , the expression is as follows .

R = ρ L / S where ρ is specific resistance , L is length of wire and S is cross sectional area .

cross sectional area = π x ( .5 x 10⁻³ )²

S = .785 x 10⁻⁶ m²

Putting the values

R = 2.82 x 10⁻⁸ x .50 / .785 x 10⁻⁶

= 1.796 x 10⁻² ohm .
