The solution for this problem would be:(10 - 500x) / (5 - x)
so start by doing:
x(5*50*2) - xV + 5V = 0.02(5*50*2)
500x - xV + 5V = 10
V(5 - x) = 10 - 500x
V = (10 - 500x) / (5 - x)
(V stands for the volume, but leaves us with the expression for x)
Answer:
Energy lost due to friction is 22 J
Explanation:
Mass of the ball m = 4 kg
Initially velocity of ball v = 6 m/sec
So kinetic energy of the ball
Now due to friction velocity decreases to 5 m/sec
Kinetic energy become
Therefore energy lost due to friction = 72 -50 = 22 J
Answer:
close to the mirrors surface
Explanation:
this is because angle of incidence equals angle of reflection
Answer:
3.16 × W/
Explanation:
β(dB)=10 ×
= W/
β=55 dB
Therefore plugging into the equation the values,

I= 3.16 × W/
Answer:
Explanation:
The equation relating the the enthalphy, pressure and temperature is expressed as
Where P is the pressure, H is the enthalphy, and T is the temperature.
since the given values are
if we insert values, we arrive at
