Mu as in the coefficient of friction?
The equation is
Ff = Fn x mu
Rearrange with the force of friction and normal force
Answer: 34%
Explanation: eff = (Eout/Ein) *100(for % form)
1200/3500 * 100 = 34%
Answer:
Final volume, V2 = 24.62 L
Explanation:
Given the following data;
Initial volume = 40 L
Initial pressure = 80 Pa
Final pressure = 130 Pa
To find the final volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
Final volume, V2 = 24.62 Liters
Answer:
An opaque object is an object through which the light rays can not be passed and we can not see from that object while transparent object allows the passage of light. Hence red apple is unable to pass light, so it is a opaque object. Hence red apple looks red because it absorbs all color except red.
