I don't know the choices but...

Answer:

Sedimentary rock is a rock formed underground, usually under a source of water too. The rock is made up of smaller rock that, over the years, fused together and solidified.

Explanation:

sedimentary rocks are the type of rocks which are formed by the accumulation or the deposition of the small particles and cementation of organic particles on the floor of the oceans or the other bodies of the water at earth's surface.

Rock material from pre-existing rocks such as metamorphic and igneous rocks that make up sedimentary rocks after some times. Types of sedimentary rocks are; Sandstone, siltstone, shale, breccia etc. formed from weathering of rocks.

1. What is the momentum of a 0.15 kg arrow that is traveling at 120 m/s?
Korvikt [17]

For this case we have that by definition, the momentum equation is given by:

p = m * v

Where:

m: It is the mass

v: It is the velocity

According to the data we have:

m = 0.15 \ kg\\v = 120 \frac {m} {s}

Substituting:

p = 0.15 * 120\\p = 18 \frac {kg * m} {s}

On the other hand, if we clear the variable "mass" we have:

m = \frac {p} {v}

According to the data we have:

p = 250 \frac {kg * m} {s}\\v = 5 \frac {m} {s}\\m = \frac {250} {5}\\m = 50 \ kg

Thus, the mass is 50 \ kg

Answer:

p = 18 \frac {kg * m} {s}\\m = 50 \ kg

Liquid water at 120 kPa enters a 7-kW pump where its pressure is raised to 5.6 MPa. If the elevation difference between the exit
ziro4ka [17]

Answer:

The answer is given below

Explanation:

Things provided in the statement:

Pressure <em>P1</em> = 120 kPa and <em>P2</em> = 5.6 MP or 5600 kPa

Power, <em>W</em> = 7 kW

Elevation difference = ∆z = 10 m

Mass of flow = m˙

So potential energy changes may be significant

Specific volume of water V= 0.001 m³/kg

Now putting the values in the formula

Power, <em>W </em>= m˙  x V (<em>P1 - P2</em>) + m˙ x g x ∆z

             7 = m˙  x 0.001 (5600 - 120 ) + m˙ x 9.8 x 10 x (1 kJ/kg/ 1000 m^2/s^2)

             7 = m˙ x 5.48 + m˙ x 0.098

             7 = m ˙x 5.38

            m˙ = 7/5.38

          So mass flow m˙  =  1.301 kJ/s

A graduated cylinder contains 62 ml of water. When a small metal block is added to the water, the volume of the water increases
lawyer [7]

Answer:

The density of the block is 7.4g/ml.

Explanation:

We can determine the volume of the metal block by taking the difference between the volumes measured in the graduated cylinder:

V_{block}=65.5ml-62ml\\\\V_{block}=3.5ml

Now, as we know that the average density of an object is calculated dividing its mass by its volume, we can calculate the density ρ of the metal block using the expression:

\rho_{block}=\frac{m_{block}}{V_{block}}\\\\\rho_{block}=\frac{26g}{3.5ml}\\\\\rho_{block}=7.4\frac{g}{ml}

Finally, it means that the density of the metal block is 7.4g/ml.
