The sequence of energy transformations associated with a hydroelectric dam is: B) gravitational potential energy into kinetic energy into mechanical energy into electrical energy

Explanation :

A hydroelectric dam is used to produce electricity. The transformation of energy that is associated with a hydroelectric dam is :

Since the water is falling from a height so at that point the potential energy of water converts into kinetic energy. The turbine attached is used to convert the energy in the water to mechanical energy.

Finally, the mechanical energy is converted to electrical energy with the help of a generator.    

Hence, the correct option is (B) " gravitational potential energy into kinetic energy into mechanical energy into electrical energy ".

Biologists use ball-and-stick models to study complex molecules by representing atoms with balls and bonds with sticks. DNA is a
AleksAgata [21]
One of the major limitations of using the ball and stick model for DNA, is that within a single double stranded segment of DNA, one would have to use many many balls to represent atoms that are present in the sugar phosphate backbone, along with all of the main atoms that compose the nitrogenous bases of DNA, we also cannot construct or show the helical form of DNA, by using balls and sticks as well.

What is the longest wavelength of light that will emit electrons from a metal whose work function is 3.70 eV
SSSSS [86.1K]

Answer:

h f = Wf + K

where the total energy available is h f, Wf is the work function or the work needed to remove the electron and K is the kinetic energy of the removed electron

If K = zero then hf = Wf

Wf = h f = h c / λ    or

λ = h c / Wf = 6.63E-34 * 3.0E8 / (3.7 * 1.6E-19)

λ = 6.63 * 3 / (3.7 * 1.6) E-7 = 3.36E-7

This would be 3360 angstroms or 336 millimicrons

Visible light = 400-700 millimicrons

An inductor is connected in series to a fully charged capacitor. Which of the following statements are true? Check all that appl
Luba_88 [7]

Answer:

As the capacitor is discharging, the current is increasing

Explanation:

Lets take

C= Capacitance

L=Inductance

V=Voltage

I= Current

The total energy E given as

E=\dfrac{IL^2}{2}+\dfrac{CV^2}{2}

We know that total energy E is conserved so when electric energy 1/2 CV² decreases then magnetic energy 1/2 IL²  will increases.

It means that when charge on the capacitor decreases then the current will increase.

As the capacitor is discharging, the current is increasing
