Answer:

P = 1.44 Watts

Step-by-step explanation:

We know that the relation between voltage and current in a simple circuit with a resistor is

V = I.R

Where

V = the voltage of the source

I = current of the circuit

R = resistance

The power is defined as

P = V.I

Which is the same as

P = V.(V/R)

P = (24 v)^2 / (400 ohm)

P = 1.44 Watts

PLEASE HELP!!! I will give brainliest answer!!! Find the volume and surface area of these.
k0ka [10]

Answer:

(I only have the answers for 3 and 4) 3. Volume: 192 Surface Area: 16 4. Volume: 1,200 Surface Area: 100

Step-by-step explanation:

3. Volume: 4 x 4 = 16 x 12 = 192 Surface Area: 4 x 4 = 16 4. Volume: 10 x 10 = 100 x 12 = 1,200 Surface Area: 10 x 10 = 100

The total weight of a rock depends on its size and is proportional to its density. In this context, density is the weight per cu
kow [346]

Answer:

d = \frac{w}{48}

If  \frac{1}{48} \\ is constant, say k

Then,

d = kw

∴ d ∝ w

Hence, weight is proportional to the density

Step-by-step explanation:

From the question,

Let w denote the weight of the rock in pounds

s denote the size of the rock in cubic inches and

d denote the density of the rock in pounds per cubic inch.

First, we will write the equation connecting w, s, and d.

We get

density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }

That is,

d = \frac{w}{s}

Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write

d = \frac{w}{48}

If  \frac{1}{48} \\ is constant, say k

Then,

d = kw

∴ d ∝ w

Hence, density is proportional to the weight OR weight is proportional to the density

A submarine was in a resting position 400 m below sea level. It rose 225 m. Determine its new depth?
Arturiano [62]

Answer:

175 meters, since its below sea level it would be- -400m - (-225m), subtracting with negative # and negative # is the equivalent of getting closer to zero, just figure out 400 - 225, and put a - symbol at the beginning of the number
