Answer:

Cubic meters is the unit of volume.

Explanation:

Volume :

Volume is the multiplication of height, width and length of the solids.

In mathematically term,

$V = w\times l\times d$

Where, w = width

h = height

l = length

Put the unit into the formula

$V = m\times m\times m$

$V =m^3$

This is the unit of volume.

We know that,

Square meters is the unit of area.

Liters per cubic gram is the unit of density.

Gram per cubic centimeter is the unit of density in CGS.

Hence, Cubic meters is the unit of volume.

What is the current in the 10.0 , resistor?

In-s [12.5K]

Answer:

B. 12.0A

Explanation:

The circuit shown in the image is a parallel circuit which mean that the voltage of the source is equal across each resistance in the circuit because they are directly connected to the terminals of the voltage source.

The voltage across the 10 Ohms resistor is 120V

So, let's proceed to calculate the current

By using Ohm's Law

$I=\frac{V}{R} \\I= \frac{120.0V}{10.0Ohm} \\I= 12.0A$

12A is the amount of current flowing through the 10 ohms resistor.

The river narrows at a rapids from a width of 12 m to a width of only 5.8 m. The depth of the river before the rapids is 2.7 m;

Alisiya [41]

Answer:

7.89 m/s

Explanation:

Given that

Width of the river, b1 = 12 m

Width of the river, b2 = 5.8 m

Depth of the river, d1 = 2.7 m

Depth of the river, d2 = 0.85 m

Speed of the river, v1 = 1.2 m/s

Speed of the river, v2 = ?

Area of the river before the rapid, a1 = 12 * 2.7 = 32.4 m²

Area of the river after the rapid, a2 = 5.8 * 0.85 = 4.93 m²

To solve this question, we use a relation between the speed of the river and the volume of the river. We say,

Area1 * velocity1 = Area2 * velocity2, and when we substitute the values for each other we have

32.4 * 1.2 = 4.93 * v2

38.88 = 4.93v2

v2 = 38.88 / 4.93

v2 = 7.89 m/s

Therefore, the speed of the river after the rapid is 7.89 m/s
