Answer:

Generally, these models have shed more light on the field of atom by describing the composition of atoms and how the atom functions . The competition of these models have been able to modify atomic model to it actual description, modification and functionality.      

Explanation:

There have been different models of atoms overtime . The competition between the various models of atom have been able to shed more light on atom and create more theory on the subject of atoms. The well known models of atom are Dalton's atomic model, Thomson's model of the atom , Ernest Rutherford model of atom, Niels Bohr's model and Schrödinger's model of atoms.

Dalton stated that atoms are indivisible and he was able to realize atom of a particular element different from others . That means atoms of the same element are identical. J.J Thompson was able to recognized electrons in atoms  he drew a plum pudding model  of an atom. It shows electron revolves around a positive charge through out a spherical cloud. Rutherford was able to detect positive charge of an atom found in the nucleus of an atom. Bohr's model modified Rutherford's model . He was able to recognized that the electron move or orbit around the nucleus. Schrödinger's  believes electrons moves around the nucleus in cloud and has an uncertain position.

Generally, these models have shed more light on the field of atom by describing the composition of atoms and how the atom functions . The competition of these models have been able to modify atomic model to it actual description, modification and functionality.

A 3.75 kg ball is lifted from the floor to a height of 1.5 m above the floor. What is its increase in potential energy?
inysia [295]
<span>We can use a simple equation to calculate the increase in gravitational potential energy. PE = mgh m is the mass of the object g is the acceleration due to gravity h is the change in height PE = mgh PE = (3.75 kg) (9.80 m/s^2) (1.5 m) PE = 55.1 Joules The increase in gravitational potential energy is 55.1 Joules.</span>

Approximately how much heat energy does it take to raise 1 kg of water by 1 k?
Sidana [21]

Answer:

4186 Joules

Explanation:

The specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 kg of the substance by 1 Kelvin. In formula,

C_s = \frac{Q}{m \Delta T}

where

Q is the amiunt of heat needed

m = 1 kg is the mass

\Delta T = 1 K

is the variation of temperature of the substance

For water, the specific heat capacity is 4186 J/(kg K). This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.

What type of potential energy is a 9 volt battery an example of?
Scilla [17]

Answer:

chemical potential energy​

Explanation:

A 9v battery comes in different formats, such that the most common one is the carbon-zinc and alkaline chemistry, so these are alkaline batteries (there are also rechargeable or lithium batteries, these also depend on chemical interactions).

These batteries "draw" the energy from chemical interactions of the materials inside of it, so the type of potential energy that is stored in a battery is actually chemical (regardless of the fact that the energy can be transformed into electrical energy later) the "potential" refers to how the energy is stored.

Then the correct option is chemical potential energy​

Force f⃗ =−10j^n is exerted on a particle at r⃗ =(7i^+5j^)m. part a what is the torque on the particle about the origin?
cluponka [151]

Answer:

Torque, \tau=0i+0j-70k

Explanation:

It is given that,

Force acting on the particle, F=-10j\ N

Position of the particle, r=(7i+5j)\ m

We need to find the torque on the particle about the origin. It is equal to the cross product of position and the force. Its formula is given by :

\tau=r\times F

\tau=(7i+5j)\times (-10j)

The cross product of vectors is given by :

\tau=\begin{pmatrix}0&0&-70\end{pmatrix}

or

\tau=0i+0j-70k

So, the torque on the particle about the origin 0i+0j-70k. Hence, this is the required solution.
