Answer:
4. Becomes softer as temperature rises
Explanation:
An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.
We already know the formula:
Voltage = Current * Resistance
In the given question, there are numerous information's that are already given.
Current = 6.2 A
Resistance = 18 ohms
Then
Voltage = 6.2 * 18 Volts
= 111.6 Volt
So, the voltage in the circuit will be 111.6 volts. I hope it helps you.
The correct answer is - c. escape.
The word ''escape'' means to get away from something. This word can be used for multiple different situations, and it can refer to both physical and psychological matters.
In a physical sense it can be used to escape from certain unpleasant, or dangerous situation. Example: I have to escape from this prison.
In a psychological sense it can be used to escape, move away, from a certain state of mind. Example: I have to find an escape from my depressive thoughts.
Answer:
The potential energy of the rock = 10.5 kN
Explanation:
Mass of rock = 25 kg
Acceleration due to gravity = 10 m/s²
Height = 42 m
Potential energy, PE = mgh, where m is the mass, g is acceleration due to gravity and h is the height.
PE = 25 x 10 x 42 = 10500 N = 10.5 kN
The potential energy of the rock = 10.5 kN
The physical law that explains that is the law of conservation of energy which states that he energy of an isolated sistem remains constant
