Nutka1998 [239]

Answer:

TERMINUS ANTE QUEM

Explanation: Terminus ante quem is an Archeological an a Latin term used to describe the date before which an event or events took place,it is also used to show the date before which Archeological works have been deposited in a given area.

Example, a pottery dating to the 4th century AD found on a surface would give that pottery with a terminus ante quem of the 4thcentury AD.

This type of cross dating can either be TERMINUS ANTE QUEM OR TERMINUS POST QUEM.

Wire A and wire B are made from the same material and are under the same tension, but waves travel along string B at one-third t

Ahat [919]

Answer:

0.3 mm

Explanation:

$\rho$ = Density of material

$\mu$ = Linear density of the material = $\rho A$

Area = Area = $\pi r^2$

r = Radius

The velocity of a wave is given by

$v=\sqrt{\dfrac{T}{\mu}}\\\Rightarrow v=\sqrt{\dfrac{T}{\rho A}}\\\Rightarrow v=\sqrt{\dfrac{T}{\rho \pi r^2}}$

It can be seen that the velocity is inversly proportional to the radius

$v\propto \sqrt{\dfrac{1}{r^2}}\\\Rightarrow v\propto \dfrac{1}{r}$

So,

$\dfrac{v_a}{v_b}=\dfrac{r_b}{r_a}$

From the question

$v_b=\dfrac{1}{3}v_a$

$\\\Rightarrow \dfrac{v_a}{\dfrac{1}{3}v_a}=\dfrac{r_b}{0.1}\\\Rightarrow 3=\dfrac{r_b}{0.1}\\\Rightarrow r_b=3\times 0.1\\\Rightarrow r_b=0.3\ mm$

The radius of wire B is 0.3 mm

Which component is transferred between substances in an oxygen-reduction reaction?(1 point)

vlada-n [284]

Answer:

electrons

Explanation:

You might mean an "oxidation-reduction" reaction, also known as a redox reaction, in which electrons are transferred between chemicals (i.e. the oxidation number changes).

An "oxygen-reduction" reaction is a very specific reaction where oxygen gas is reduced to water or hydrogen peroxide.
