(C)

Explanation:

t = 2\pi \sqrt{ \frac{l}{g} }

If g is only 1/6 on another planet, then

t = 2\pi \sqrt{ \frac{l}{ \frac{g}{6} } } =  2\pi \sqrt{ \frac{6l}{g} }

=  \sqrt{6} \: (2\pi \sqrt{ \frac{l}{g} } ) = 2.4  \times t(on \: earth)

How do u calculate momentum
Helga [31]

Answer:

Explanation:

To calculate the momentum of a moving object multiply the mass of the object times its velocity. The symbol for momentum is a small p. So, the momentum of the object is calculated to be 8.0 kg-m/s. Note the unit for momentum.

If the work required to stretch a spring 1 ft beyond its natural length is 12 ft-lb, how much work is needed to stretch the same
Angelina_Jolie [31]

Answer:W=\frac{3}{4} ft-lb

Explanation:

Given

Work required to stretch 1 ft is 12 ft-lb

and we have to find work required to stretch 3 in.

i.e. \frac{1}{4} ft

12=\frac{1}{2}K\left ( 1\right )^2 ------(1)

W=\frac{1}{2}k\left ( \frac{1}{4}\right )^2-----(2)

divide (1)&(2)

\frac{12}{W}=\left ( \frac{4}{1}\right )^2

W=\frac{12}{4\times 4}

W=\frac{3}{4} ft-lb

cogeneration plants are different from regular commercial generating stations because the heat, after it generates electricity,
statuscvo [17]

Answer:

Central heating plant or manufacturer.

Explanation:

Co generation plants are useful in the sense that they do not let the thermal energy wasted for heating, they utilize it. They use that heat to drive the steam or gas turbine- powered generators. However the regular commercial generating stations do not do that.

A note is played on a flute. Which of the parts of the wave would be affected by playing a higher pitch note and how? A) D, the
blagie [28]

Answer: The frequency would get higher and wavelength would get shorter.

Explanation:

Pitch is directly related to frequency. Frequency is perceived in the form of pitch. High pitch means high frequency and low pitch means low frequency. When a note is played on the flute, playing it on a higher pitch would affect the frequency and wavelength. Frequency would get higher and because wavelength is inversely proportional to the frequency, it would get shorter.
