Answer:
sorry I didn't know the answer
Explanation:
ok
Physical change because it's only changing the shape of the gold.
This problem can be solved by using ideal gas equation PV=nRT. The unit used in the pressure is kPa so you will need to convert it. The temperature also use Kelvin, you will need to convert it if you want it in C.
The calculation would be:
PV= nRT
16.4 atm * (101.35kPa/atm) * 18.35 L = <span>12.2 </span>mol *T * (8.314 L*kPa/mol*K)
T=30500 /101.4308
T= 300.70 °K = 27.55 °C
Answer:
98.356 ohms is the answer
Answer:
The angle at which the light from the ray box strikes the mirror
Explanation:
The independent variable is the variable that the investigator changes. The question states that Alice "changed the angle at which the light from the ray box struck the mirror."
The light box and the direction of the ray are wrong. They are controlled variables.
The angle of the reflected light is wrong. It is the dependent variable.
