Answer:
P.E.=29.4Nm
Explanation:
given data
m=1kg
h=3m
g=9.8m/s²
to find
gravitational potential energy=P.E.=?
solution
P.E.=mgh
PUTTING VALUES
P.E.=1kg×9.8m/s²×3m
P.E.=29.4Nm
Power in a wire where current is flowing can be calculated from the product of the square of the current and the resistance. Resistance is equal to the product of resistivity and length divided by the area of the wire. We do as follows:
Resistance = 2.44 × 10-8 ( 0.11) / (π)(0.0009)^2 = 1.055x10^-3 <span>Ω
P = I^2R = .170^2 (</span>1.055x10^-3 ) = 3.048x10^-5 W
Answer:Whenever a moving object experiences friction, some of its kinetic energy is transformed into thermal energy. Mechanical energy is always transformed into thermal energy due to friction. Mechanical energy is always transformed into thermal energy due to friction.
