Answer:
By putting something like a sheet of glass in the water.
Explanation:
Putting a sheet of glass in the water will make the ripples move slower because the speed of a wave depends on the depth of water.
It's 30 AU extending from the ordit of Neptune to approximately 50 AU from the sun
Hopefully this help
Answer:

Explanation:
Take at look to the picture I attached you, using Kirchhoff's current law we get:

This is a separable first order differential equation, let's solve it step by step:
Express the equation this way:

integrate both sides, the left side will be integrated from an initial voltage v to a final voltage V, and the right side from an initial time 0 to a final time t:

Evaluating the integrals:

natural logarithm to both sides in order to isolate V:

Where the term RC is called time constant and is given by:

If the pressure acting on a given sample of an ideal gas at constant temperature is tripled, the volume is reduced to one-third of its original value. <em>(a)</em>
Answer:
7506 cal
Explanation:
Given: Mass of water = m = 13.9 grams.
Heat energy required to determine the conversion of 13.9 grams of water to steam or vapor is m L,
where L = Latent heat of vaporization of water=540 cal/g.
Q = mL = (13.9)(540) = 7,506 cal.
