Answer:

Explanation:

In Bohr’s atomic model electrons move in discrete orbits around the nucleus of an atom. The energy of the electrons are quantized. Bohr’s model explained that electrons move with a certain angular momentum in discrete orbits. Bohr’s model explained why electrons do not spin into the nucleus and thus proved the stability of atoms.

A discus thrower throws a 1.6kg discus at 25m/s what's the kinetic energy?

Ilya [14]

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

$k = \frac{1}{2} m {v}^{2} \\$

where

m is the mass

v is the velocity

From the question

m = 1.6 kg

v = 25 m/s

We have

$k = \frac{1}{2} \times 1.6 \times {25}^{2} \\ = 0.8 \times 625 \\ = 500$

We have the final answer as

Hope this helps you

How to solve 2=-log(x)

ch4aika [34]

First, you want to extract the negative from -log(x).

So now you have log(x) = -2

Now you have to use the property loga(x)=b is the same as x=a^2

So now, it is x = 10^-2. Remember that when there is just a log, it is implied that it is ‘a’ is 10.

Then you evaluate the negative square to 1/10^2

Answer is 1/100

What are nanochemicals and what are there uses?

NARA [144]

Nanochemicals can be defined as chemicals generated by using nanomaterials (materials that possess of size on nanometer dimensions). The nanochemicals are used in multiple different applications including chemical warfare, bicycle making, armor design and military weapons crafting. The most commonly used and observed nanochemicals are carbon nanotubes that are used a ton in industry for applications such as stronger materials (stronger bicycles).

Smart materials are exquisitely designed materials whose property(ies) can be modified with the use of an external stimulus such as temperature, stress, pH, and so on. Some examples of smart materials include shape memory materials, piezoelectric materials, ferrofluids, self-healing materials, and such. Applications involve memory pillows, memory based solar panels (for satellites), light sensitive glasses, and so on.

Specialized materials are made specifically to perform a specified task or function. Applications involve electronic equipment (high purity silicon & germanium), machine tools (high tungsten high carbon steel), dental filling (dental amalgam), and so on.

What is the transition element which despite its strength (rigidity), it is characterized by being ductile, and by its high resi

uranmaximum [27]

Titanium is ductile and has high resistance for heat despite its strength.

Titanium (Ti), is a Group 4b chemical transition element, it has a silvery gray appearance. Its characteristics are as follows

known as the strongest metal with high rigidity
low-corrosion resistance
low density
heat resistance.

Because of these features, Titanium is widely used in building aircraft, missiles, and ships and also in the production of prosthetics.
