Answer:
the answer is mechanical energy
Explanation:
A water wheel converts the kinetic energy of moving or falling water into mechanical energy. This mechanical energy is used for powering the mill.Water wheels have wooden or metal wheels that have buckets or blades attached around them. They are placed in a river or lake. The force of the water rotates the wheel. As the wheel moves, it turns an axle attached horizontally to the wheel. The axle in turn moves the system of gears that operate the functioning of mills. Waterwheels were used for preparing fiber and crushing ore.
The solution of which contains of PH 3 called acidic medium which is more stronger acid called HCl when reacts to the stronger base base NaOH forms the acid base reaction .
According to acid base equation you consider ph5 as PH 9 if you understand it then tell me below
Answer: The new volume of the balloon is 33 liters while T2 is 301K
Explanation:
Initial volume of helium V1 = 31 liters
Initial temperature T1 = 9°C
Convert temperature in Celsius to Kelvin
( 9°C + 273°C = 280K)
Final temperature T2 = 28°C
( 28°C + 273°C = 301K)
Final volume V2 = ?
According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.
Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2
31/280 = V2/301
To get the value of V2, cross multiply
V2 = (31 x 301) / 280
V2 = 9331 / 280
V2 = 33.325 liters (approximated to 33liters)
Thus, the new volume of the balloon is 33 liters while T2 is 301K
Answer:As an ice cube melts, its shape changes as it acquires the ability to flow. However, its composition does not change. Melting is an example of a physical change .
Explanation:
The correct answer is the combination of a metal with another element.
An alloy is a combination of two or more metallic elements to make a stronger material. For instance, there are bronze alloys, brass alloys, and coin alloys.
We can confirm that an alloy is a combination of one metal with another metal because stainless steel is made of an iron and chromium alloy (iron is a metal; chromium is also a metal). Therefore, we can confirm that option C is the best choice.
