The answers to your questions are as written below:
- The objects that represents a negatively charged particle is : Image B
- The object that represents a positively charged molecule is : Image A
- The object that represents an uncharged molecule is : Image C
- The object the will not move when in an electric fied is : Image C
<h3>Different types of charges molecules</h3>
A negatively charged molecule move inwards when placed in an electric field while positively charged molecule placed in a electric field will move outwards the electric field.
A neutral/uncharged molecule will remains still when placd in an elctric field due to the absence of charges.
Hence we can concude that the answers to your questions are as listed above.

The energy of a single photon is given by:
where
E is the energy
h is the Planck constant
f is the frequency of the light
The light in our problem has a frequency
, so the energy of each photon of that light is:
Answer: It formed when lava cooled quickly aboveground.
Explanation: Cause its right
Each of the choices may be considered right depending on the use
of context or on how terms are defined, but the one that is most correct is:
"Controlled experiments
produce valid data"
Controlled experiments are experiments in which factors which are
not the interest of the study or which are not being studied are controlled or
accounted for in the design, so that resulting data are less likely to be
caused by some anomaly or by some variable other
than those being
studied. In usual research scenarios it is not the data itself that
is acted upon in the <span>experiment - it is the experiment itself, the
factors and the physical processes that will eventually yield data.</span>
<span>Human ear can hear the lowest frequency about 20 Hz, this is 20 vibrations per second. Vibrations of pendulum are very small and frequency is less than 20 Hz, so we can't hear it.</span>
