The statement that describes an insulator is A. It has a high resistivity because it opposes the movement of electrons.
Insulators simply mean the electrical equipment that are used to support electrical conductors as well as separate them as they do not allow the passage of current.
In an electrical insulator, the electric current doesn't flow freely. It possesses a high resistivity because it opposes the movement of electrons.

I have to get this done today How does the thermal energy of a swimming pool compare to the thermal energy of a lake at the same temperature? A.Thermal energy is the total kinetic energy of the particles in a substance. The lake is more spread out, so it contains fewer total particles than the swimming pool. Therefore, the thermal energy of a lake is less than that of a swimming pool.B.Thermal energy is the total kinetic energy and potential energy of the particles in a substance. The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger.C.Thermal energy is the total potential energy of the particles in a substance.

The phase is frequently used to describe transitions between the three fundamental states of matter. Condensation is the phase change in the atmosphere forms clouds.
What is phase transition?
The physical process of changing a medium's state from one to another is known as a phase transition in the domains of chemistry, thermodynamics, as well as other related sciences. The phase is frequently used to describe transitions between the fundamental states of matter.
The physical characteristics of a phase of such a thermodynamic system as well as the states of matter are constant. Some properties of a particular medium change throughout a phase transition as a result of a change in the environment, including such temperature or pressure. Condensation is the phase change in the atmosphere forms clouds.
Therefore, condensation is the phase change in the atmosphere forms clouds.

Answer:
a) = -30 m/s
b) = 30 m/s
Explanation:
a)
Consider the car A travel at a velocity of = 90 km/h and the car B travel at the velocity of
= 120 km/h. As the velocity of the car B is greater than the car A, So it cross the car A. Consider The velocity of car A relative to car B is
and it is equal to the velocity of car A minus the velocity of car B.
=
-
= 90 - 120
= -30 m/s
b)
Consider The velocity of car B relative to car A is and it is equal to the velocity of car B minus the velocity of car A.
=
-
= 120 - 90
= 30 m/s

Jenny's acceleration was negative during the intervals of time when her speed was decreasing.
That's really all we can tell, because you really haven't given us any information except her name.
Final answer:
Negative acceleration refers to times when Jenny was slowing down in her motion. Exact intervals cannot be given without further information on her motion timeline or graphical representation.
Explanation:
The periods during which Jenny was negatively accelerating would be the time intervals during her motion when her speed was decreasing. In a physics context, negative acceleration (or deceleration) means that the object (in this case, Jenny) is slowing down. For instance, if Jenny was running and began to slow down, the period from when she began slowing to when she stopped would be an interval of negative acceleration. However, without specific timelines or a graphical description of Jenny's motion, it's impossible to determine the exact intervals of negative acceleration.
