Answer:

Thermocline.

Explanation:

The sunlight does not reaches deep inside the water called as the deep layer in which the temperature of water is low and it is cold. These two layers are separated by the middle layer called as the thermocline, which is warm at the top and cold at the bottom.

You have a battery marked " 6.00 V 6.00 V ." When you draw a current of 0.383 A 0.383 A from it, the potential difference betwee

Archy [21]

Answer:

V = 4.81 V

Explanation:

As the potential difference between the battery terminals, is less than the rated value of the battery, this means that there is some loss in the internal resistance of the battery.
We can calculate this loss, applying Ohm's law to the internal resistance, as follows:

$V_{rint} = I* r_{int}$

The value of the potential difference between the terminals of the battery, is just the voltage of the battery, minus the loss in the internal resistance, as follows:

$V = V_{b} - V_{rint} = 5.03 V = 6.0 V - 0.383 A* r_{int}$

We can solve for rint, as follows:

$r_{int} = \frac{V_{b}-V}{I} =\frac{6.0V-5.03V}{0.383A} = 2.53 \Omega$

When the circuit draws from battery a current I of 0.469A, we can find the potential difference between the terminals of the battery, as follows:

$V = V_{b} - V_{rint} = 6.0 V - 0.469 A* 2.53 \Omega= 6.0 V - 1.19 V = 4.81 V$

As the current draw is larger, the loss in the internal resistance will be larger too, so the potential difference between the terminals of the battery will be lower.

What is the velocity of a wave that has a wavelength of 20 meters and frequency of 0.5 Hz?

k0ka [10]

Answer:

v = 10 m/s

Explanation:

recall that velocity is related to wavelength and frequency by the formula

v = fλ

where v = velocity, f = frequency and λ= wavelength

Simply substitute these into the formula:

v = fλ

v = (0.5)(20)

v = 10 m/s

A water heater that has the shape of a right cylindrical tank with a radius of 1 foot and a height of 4 feet is being drained. h

Natali5045456 [20]

For any prism-shaped geometry, the volume (V) is assumed by the product of cross-sectional area (A) and height (h).

V = Ah

Distinguishing with respect to time gives the relationship between the rates.
dV/dt = A*dh/dt

in the meantime the area is not altering

dV/dt = π*(1 ft)^2*(-0.5 ft/min)

dV/dt = -π/2 ft^3/min ≈ -1.571 ft^3/min

Water is draining from the tank at the rate of π/2 ft^3/min.
