Answer: If i'm not mistaken I think it A) potential
Answer:
force on larger piston = <em> </em>
Explanation:
we label the pistons as piston A and piston B
small piston A:
area = a
force = f
large piston B:
area = A
force = ?
<em>Pascal's law of pressure state that the pressure delivered to a liquid is transmitted undiminished to every portion of the fluid.</em>
we know that pressure = force ÷ area
pressure of piston A =
pressure of piston B =
obeying Pascal's law, the system pressures must be equal. Therefore
force on large piston (B) = F =<em> </em>
You use the equation potential energy= mass x gravity x height. 10x2x9.8=196.
Answer:
Explanation:
moment of inertia of the disc I = 1/2 m r²
= .5 x 8 x .25²
= .25 kg m²
The wok done by force will be converted into rotational kinetic energy
F x d = 1/2 I ω²
F is force applied , d is displacement , I is moment of inertia of disc and ω
is angular velocity of disc
41 x .9 = 1/2 x .25 ω²
ω² = .25
ω = 17.18 rad / s
Answer:
W = 200 J
Explanation:
Work will be equal to the change in kinetic energy
W = ½mv² - 0
W = ½(0.010)200²
W = 200 J
