Answer:
c.exists as a crystalline solid
Explanation:
Amongst all the three phases, it is solid phase which is the most compact because the atoms within the solids are bound with a very strong force of attraction. But, solids can exist as either crystalline solid or amorphous solid. Between these two type of solids, it is crystalline solids which are very well packed and the inter atomic distance between their two atoms is the least. It is due to the reason that the atoms within a crystalline solid are arranged in proper order in the form of stacks. But, in amorphous solids the atoms are not arranged properly i.e. their arrangement is random which leads to the increased inter atomic distance. Second comes liquid phase, in liquids the inter atomic forces are intermediate between solids and gases. Atoms in a gas are bound with the weakest force of attraction known as van der Waals that is why the distance between the atoms of a gas is the highest.
Explanation:
The amount of matter contained inside a body is called its mass while the weight of a body is the gravitational force with which it is attracted towards the earth.
Weight, W = mg
m is the mass and g is acceleration due to gravity
The mass of the object on the moon remains the same but the weight of the body is reduced to one sixth. This is because the moon's gravity is less than the earth's gravity.
Hence, this is the main difference in the weight of the object on the earth and on the moon.
B. It increases the potential energy of electrical charges to produce a current.
C. It increases the kinetic energy of electrical charges to produce a static discharge.
D. It transfers electrons through induction so they generate electrical energy.
Answer:
B. It increases the potential energy of electrical charges to produce a current.
Explanation:
Battery is a source of constant potential difference
When a charge is passed through the battery then its potential energy changes by
here we know that
= potential difference of battery
so as the charge is passing through the terminals of battery its potential energy is changed by above value.
Now by the conservation of energy principle we know that this change in potential energy will convert into kinetic energy of charge and then the flow of charge will produce current in the circuit.
So battery is used to maintain a constant current in the circuit by giving potential energy to the charge.
b. light wave
c. longitudinal wave
d. water wave
This question comes along with four answer choices:
a) the thermal energy moving from the coffee to her tongue
b) the thermal energy moving from her tongue to the coffee
c) her coffee
d) her tongue
Answer: a) the thermal energy moving from the coffee to her tongue.
Explanation:
Heat, heat energy and thermal energy are terms to refer the same thing.
Heat is the kinetic energy of the molecules or particles in a substance wich is transferred from hot substances to cool substances.
In the example, the coffe is hot and Ixchelt's tongue is cool, so the heat is the thermal energy transferred from the hot coffe to Ixtchel's tongue.
The thermal energy (heat) always flows from the hot to the cold, never the other way around.
