At the top, the roller coaster has a very large amount of potential energy. This amount of potential energy is present because the roller coaster is at a elevated place with respect to the ground. While the roller coaster goes down some of the potential energy is lost depending on the change in height and is converted to other energy. As the roller coaster is losing the potential energy, it gains some kinetic energy since this type of energy is dependent on the speed of the object moving and the mass. Therefore the answer i believe is where potential energy is converted to kinetic energy.
Answer:
electron shell
Explanation:
the proton and nucleus are inside the electron shell so the arrow is point on the outer shell which is the electron shell.
Answer:
20 m/s
Explanation:
First, you have to convert kilometers (72) to meters (72.000) then do the same with hours (1 hour) and seconds (3.600) Divide this numbers and you will get a result.
Answer:
i hope it help
Explanation:
It's possible to step 12 volts down to 6 volts by incorporating a pair of 10,000-ohm resistors into the circuit. Cut two lengths of wire, and strip each wire of 1/2 inch of insulation at each end. Attach one end of the first wire to the positive terminal on the power supply.
Answer:
both side charges will exert force on central charge towards left so the two forces add up. Thus resultant force on centre charge is
F = 9×10^9 x 8×10^-6×10×10^-6/16
+
9× 10^9 × 10×10^-6×12×10^-6/64
= 9× 10^9 × 10^ -12/16 (80+30)
=6.18 × 10^-2 N
or
= 0.06 N
