During anomalous expansion of water ,heat transfer is limited to conduction and radiation only ,explain.
Heat transfer is limited to conduction and radiation only in anomalous expansion of water simply because of the temperature at which the expansion occurs and density
What is anomalous expansion of water?Anomalous expansion of water is a property of water in which water expands instead of contracting.
Anomalous expansion of water makes water less dense. The major effect of this anomalous expansion it will still remain less dense and at the surface of water.Interestingly, this expansion occurs when it is cooled from 4°C to 0°C.Learn more about properties of water:

How many electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form? 1 3 4 8
Answer:
8
Explanation:
It is because the outermost energy level carries a maximum of 8 electrons
8 electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form
What is a covalent bond?The interatomic bond is formed when two atoms share an electron pair. The electrical attraction of their nuclei for the identical electrons causes the binding.
When the total energy of the bound atoms is lower than that of widely spaced atoms, a covalent bond is formed.
When an atom's outermost electron shell is full, it is the most stable and least reactive. The octet rule states that most key biological elements require eight electrons in their outermost shell to be stable.
Hence 8 electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form

If carrots have 80j of energy how much energy will a rabbi get from eating the carrot
Answer:
8
Explanation:
According to the 10% law of energy transfer,
only about 10% of energy will be transferred to
the successive level from the previous trophic
level. Therefore according to this law carrot will
have the highest energy level as it is present at
the lowest trophic level.
Then it will transfer 10% of its consumed energy
to the rabbit and then snakes will get 10%
energy of rabbit after consuming it. Therefore if
the energy amount is given it can be calculated
by dividing it by 10 for upper trophic level.
So if a rabbit receives 80 calories of energy
from eating carrots it will pass only 8
(80/10=8) calory of energy on to a snake.
Therefore the correct answer is 8 calories

If the temperature of water in which the sound wave travels
decreases from 90°C to 50°C, then what will happen to the
velocity of the wave?
till
The sound wave travels faster at higher temperatures and slower at lower temperatures.
What will happen to the velocity of the wave if the temperature decreases?At a lower temperature, particles of the medium are moving more slowly as compared to higher temperature. Due to lower temperature, longer time is required to transfer the energy of the sound waves.
So we can conclude that sound travels faster at higher temperatures and slower at lower temperatures.

Can someone help me, I'll give you brainliest!!! (For Dark Paradox)
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
What Daryl said is correct and the relationship among them is a causation than a correlation, because we know that high pitched sound wave has more frequency than that of low pitched sound wave. and we also know that if the medium is same then velocity of wave is same* so if there is high pitched sound wave, it has shorter wavelength and if there's low pitched sound wave it has longer wavelength. since there's an inverse relationship between wavelength and frequency.

During which phase of the moon can a lunar eclipse happen?.
can someone please tell me how to calculate the initial kinetic energy
In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2

Which of the following is a consequence of the special theory of relativity?
A) A moving object's mass is constant regardless of its speed.
B) Time slows as the speed of an observer's frame of reference increases
C) A stretching of time due to a moving object can be seen under normal conditions
D) It is possible for an object with mass to travel at the speed of light.
Answer:
D.
Explanation:
Specifically, Special Relativity showed us that space and time are not independent of one another but can be mixed into each other and therefore must be considered as the same object, which we shall denote as space-time. The consequences of space/time mixing are: time dilation. and length contraction.

These brown dwarfs can be distinguished from other star-like objects because they exhibit absorption lines from the ammonia molecule in the spectra.
What are brown dwarfs?Brown dwarfs are star-like (small) objects in the external space that exhibit very low cold temperatures.
Brown dwarfs are not only small stars but also huge gaseous planets such as Saturn and Jupiter.
In consequence, brown dwarfs are a wide category that includes both planets and star-like objects.

A solid cylindrical disk has a radius of 0.15 m. It is mounted to an axle that is perpendicular to the circular end of the disk at its center. When a 50-N force is applied tangentially to the disk, perpendicular to the radius, the disk acquires an angular acceleration of 110 rad/s2. What is the mass of the disk?
Answer:
Torque = I α = 1/2 M R^2 α where α is the angular acceleration
Torque = F R where F is applied to a distance R from center
F R = 1/2 M R^2 α
M = 2 F / (R α) = 2 * 50 / (.15 * 110) = 6.06 kg
