Answer:
16.7
Explanation:
Mechanical advantage is the ratio of the output force to the input force.
MA = Fout / Fin
MA = 2000 N / 120 N
MA ≈ 16.7
is our feeling depend or electrostatic force
no our feelings doesn't depends on electrostatic force
Answer:
Decrease
Explanation:
Working at a constant temperature when more pressure is exerted, the volume decreases.
This is known as Boyle's law.
According to Boyle's law;
"the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states.
#3). c
#4). b
#5). d
Does it mean as much as you thought it would ?
Answer:
Explanation:
A solid is Sphere is somehow place inside a solid cube and the system is heated .
Material of cube and Sphere is same therefore coefficient of volume expansion is same for both shapes.
change in volume is given by
where
As initial volume of Cube is more than the sphere therefore Cube will expand more keeping other two factors same.
