Question 1 (1 point)

Physics
1 answer:
velikii [3]3 years ago
3 0

Answer:

zirconium

Explanation:

in a liquid, the distance between particles is usually greater than in a solid (with the notable exception of water). Nevertheless, the forces of attraction between particles make liquids, like solids, virtually incompressible. However, the freedom of movement of the particles of liquids is greater than that of the particles of solids.

As his socks tumbled in the dryer, they became charged. If a small piece of lint with a charge of +1.25 E -19 C is attracted to
qwelly [4]

Answer:

2.4\cdot 10^{10}N

Explanation:

When an electric charge is immersed in an electric field, it experiences a force given by the equation

F=qE

where

q is the charge

E is the magnitude of the electric field

In this problem, we have:

q=+1.25\cdot 10^{-19}C is the charge on the small piece of lint

F=3.0\cdot 10^{-9}N is the force experienced by the  charge

Therefore, we can find the magnitude of the electric field by re-arranging the equation and solving for E:

E=\frac{F}{q}=\frac{3.0\cdot 10^{-9}}{1.25\cdot 10^{-19}}=2.4\cdot 10^{10}N

A subtence floats or sinks in onother becauseof its relitivity
Helga [31]
No.  A substance floats or sinks in another substance because of
the densities of both of them.

If the density of the substance is more than the density of the other
one, it will sink.  If less than the density of the other one, it will float.

1. A plane mirror has a<br>surface​
kenny6666 [7]

Answer:

A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface).

Why is it necessary to centrifuge out any precipitate formed in the unknown solution and continue testing the remaining unknown
jonny [76]

Answer:

Precipitation is the formation of a solid from a solution. It is necessary to centrifuge the precipitate to exert sufficient forces of gravity to bring the solid particles in the solution to come together and settle

Explanation:

When you centrifuge precipitate it enables the nucleation to form.

Centrifuging the precipitate helps in determining whether a certain element is present in a solution or not.
