Answer:
m = 3,265 10⁻²⁰ E
Explanation:
For this exercise we can use Newton's second law applied to our system, which consists of a capacitor that creates the uniform electric field and the drop of oil with two extra electrons.
∑ F = 0
- W = 0
the electric force is
F_{e} = q E
as they indicate that the charge is two electrons
F_{e} = 2e E
The weight is given by the relationship
W = mg
we substitute in the first equation
2e E = m g
m = 2e E / g
let's put the value of the constants
m = (2 1.6 10⁻¹⁹ / 9.80) E
m = 3,265 10⁻²⁰ E
The value of the electric field if it is a theoretical problem must be given and if it is an experiment it can be calculated with measures of the spacing between plates and the applied voltage, so that the system is in equilibrium
We can make the claim that light can be reflected, which is justified by the reflection seen on the water as well as the colors seen in the photo.
<h3>How can we tell that light is being reflected?</h3>
We can claim that light can and is being reflected in this image due to the reflection in the water as well as the colors. As the light traveling in the air collides with the water, it abruptly changes speed, causing a portion of these waves to be reflected back, thus creating a mirror image on the surface of the water. This is also the case with colors, which are caused by a material reflecting all but one wavelength of light.
Therefore, we can confirm that it is possible to make the claim that light can be reflected, which is justified by the reflection seen on the water as well as the colors seen in the photo.

Answer:
yes
Explanation:
By definition, the speed of an object is the rate of change of its position.Velocity, on the other hand, is the measurement of the rate and direction of change in the position of an object. Since it is a vector physical quantity, both magnitude and direction are required to define it
After equal masses absorb equal amounts of heat, the substance
with the greatest 'specific heat capacity' will have the smallest change
in temperature.
The specific heat capacities of those substances are ...
Water . . . . . 4,181 joules per kilogram-°C
Lead . . . . . . . . 125.6
Iron . . . . . . . . . 460.5
Basalt . . . . . . . . . 0.84
It looks like water is the easy winner.
THAT's why, in the days before electric blankets, hot-water bottles
were used to warm up a cold bed ... not hot-iron bottles or hot-basalt
bottles. A pound of hot water brings much more heat to the sheets
than a pound of any of those others.
A carbon sink is a depository for carbon dioxide and tripical forests are very efficient.
