W = 980N. The weight of an object of 100Kg in the Earth is 980N.

The weight is a measure of the gravitational force acting on an object, the weight is equivalent to the force exerted by a body on a point of support, caused by the action of the local gravitational field on the mass of the body.

it can be defined as the product of mass by the acceleration of gravity, w = mg. Since weight is a force, its unit is the Newton N.

If the mass of an object on earth is 100 kg, then is weight is:

W = (100Kg)(9.8m/s²) = 980N.

The type of chemical bond that involves the transfer of electrons between atoms is a(n) bond.

GaryK [48]

<h3>Answer;</h3>

<em>-Ionic bond</em>

<h3>Explanation;</h3>

<u>Ionic bond</u> is a type of bonds that results from transfers of electrons from one atom to another. This types of bond is formed between metals and non metals.
Metals lose electrons to form cations (positively charged ion) and non metals gain electrons forming anions, negatively charged ion.
For instance; between sodium and chlorine element; sodium donates a single electron to attain a stable configuration while chlorine gains an electron to achieve stable configuration, thus forming an ionic compound sodium chloride.

What is the energy of a 4kg apple that is sitting on a 2 m high tree branch?

miv72 [106K]

78.4 joules is the energy of a 4 kg apple that is sitting on a 2 m high tree branch.

<u>Explanation: </u>

When an apple falls to the ground from a tree, its positional energy (stored as potential gravitational energy) turns into kinetic energy, during a fall. Chemical potential energy is chemical energy because it is food and potential energy as it can still have ability to move. So, in the given case, kinetic energy is zero.

To find potential energy, the formula would be

$\text { potential energy }(P . E)=m \times g \times h$

Where, given

m – Mass – 4 kg

$g-\text { Earth'sgravity }-9.8 \mathrm{m} / \mathrm{s}^{2}$ (Known value)

h – Height - 2 m

Substitute these values, we get

$P . E=4 \times 9.8 \times 2=78.4 \text { joules }$

What is the difference between condensation and conduction

aniked [119]

Answer:

Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle.

Their a difference....... A huge One
