Answer: Thermal energy from the fire moves to the water in the form of heat.

Because according to second law of thermodynamic, heat flows from higher to lower temperature region. Heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects

Sayyid drew a diagram to compare the gravitational and

Jlenok [28]

Gravitational: A.is attractive only

Electromagnetic: C.attracts and repels

Both: D.has an infinite range

Explanation:

The two forces mentioned in this problem are:

- Gravitational force: this force is the force that is exerted between any object with mass. The magnitude of the force is given by

$F=G\frac{m_1 m_2}{r^2}$

where

G is the gravitational constant

m1 and m2 are the masses of the two objects

r is the distance between the objects

This force is always attractive and it has an infinite range.

- Electromagnetic force: this is the force exerted between electrically charged objects. The magnitude of the force is given by

$F=k\frac{q_1 q_2}{r^2}$

where

k is the Coulomb's constant

q1 and q2 are the charges of the two objects

r is the distance between them

This force is attractive when the charges have opposite sign and repulsive when they have the same sign. It also has an infinite range.

Therefore, we can conclude that:

Gravitational: A.is attractive only

Electromagnetic: C.attracts and repels

Both: D.has an infinite range

Answer:

Associative learning may be defined as a type of learning in which the new response gets easily associated with the stimulus. Except habituation learning all simple learning procedure are included in this learning.

In the associative learning, reactions of an individual are based on there spank. George learns to cry on being spanked this is because this stimulus of sister cries gives response. Crying do not show any effect on ken because he does not know about his sister crying.

What are fossils and how do scientists use them to understand evolution.

bonufazy [111]

Hello User!

Answer:

Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.

Explanation:

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms

Jason most likely has Bipolar Disorder.

Explanation: Manic episodes may include symptoms such as high energy, reduced need for sleep, and loss of touch with reality. Depressive episodes may include symptoms such as low energy, low motivation, and loss of interest in daily activities. Mood episodes last days to months at a time and may also be associated with suicidal thoughts.
