Answer:
p = 120000 kg · m/s
Explanation:
p = mv
p=momentum
m=mass
v=velocity
p = (4800)(25)
p= 120000 kg · m/s
Answer:
[tex]momentum = mass \times velocity \\ = 4800 \times 25 \\ = 120000 \: kgm {s}^{ - 1} [/tex]

Jerome has a tow truck, and he is in charge of moving several vehicles for the city. He wants to explain to his niece how towing vehicles relates to Newton's second law. Which statement should he use?
Answer:
Force = mass x acceleration
Explanation:
According to the Newton's second law, the net force acting on the object is proportional to the rate of change of momentum of the body.
So, Force is given by
F = m a
where, F is the force, m is the mass and a is the acceleration.
when the mass is more, the acceleration is less as the force applied by the truck is same.
The lower the pH number is, the more ______ the solution.
Answer:
more acidic (less base)

Señala cual de las siguientes propiedades de una sustancia son propiedades características= masa densidad volumen belleza conductividad eléctrica
Answer:
i) densidad
ii) conductividad eléctrica
Explanation:
Las propiedades características de una sustancia se denominan también propiedades intrínsecas. Estas son propiedades que no dependen de la cantidad de sustancia presente.
Las propiedades características se pueden utilizar para identificar una sustancia porque son propiedades que siempre debe exhibir la sustancia.
Entre las opciones, podemos encontrar las siguientes sustancias características;
i) densidad
ii) conductividad eléctrica

Explanation:
4) The net torque on the on the meter stick is equal to zero in order to have no rotation.
[tex]\tau_{1} = \tau_{2}[/tex]
[tex]F_{1}d_{1} = F_{2}d_{2}[/tex]
[tex](8 \:N)(0.3\: m) = F_{2}(0.1 \:m)[/tex]
[tex]F_{2} = \frac{(8 \:N)(0.3 \:m)}{(0.1 \:m)} = 24 \:N[/tex]
5) We are going the same equations in #4 here.
[tex]F_{1}d_{1} = F_{2}d_{2}[/tex]
[tex](500 \:N)(2.4 \:m) = F_{2}(3.0 \:m)[/tex]
[tex]F_{2} = \frac{(500 \:N)(2.4 \:m)}{(3.0 \:m)} = 400 \:N[/tex]
Si un automóvil logra una potencia util promedio de 250kw y se sabe que tiene un rendimiento energético del 25%. ¿Cuanta energia total consume en 1 min? Exprese el resultado en kj
Answer:
W = 3.75 kJ
Explanation:
Power is defined by the relational
P = W / t
W = P t
the yield is 25% = 0.25
W = 0.25 Wo
W = 0.25 250 60
W = 3750 J
W = 3.75 kJ
The speed of light in vinegar is 2.30 x 10^8 m/s. Determine the index of refraction. (2
Answer:
[tex]n _{v} = \frac{c}{v} \\ = \frac{3 \times {10}^{8} }{2.30 \times {10}^{8} } \\ = 1.30[/tex]
This question involves the concept of refractive index.
The refractive index of the vinegar is "1.3".
What is the Refractive Index?The refractive index is defined as the ratio of the speed of light in air and the speed of light in the given medium which is vinegar here.
[tex]\eta = \frac{c}{v}[/tex]
where,
[tex]\eta[/tex] = refractive index = ?c = speed of light in air = 3 x 10⁸ m/sv = speed of light in vinegar = 2.3 x 10⁸ m/sTherefore,
[tex]\eta = \frac{3\ x\ 10^8\ m/s}{2.3\ x \10^8\ m/s}[/tex]
η = 1.3

Arches National Park is a desert landscape located in Utah. The park is filled with arches that have been formed by nature. The arches were once solid rock. Over time, extreme temperature changes and windy conditions have caused pieces of rock to crumble and blow away, leaving holes in the rock and forming the arches. Which of these processes is responsible for the formation of the arches?
a.cooling magma
b.weathering and erosion
c.compaction and cementation
d.increased geological pressures

1. Mineral in the earth's crust exists naturally in form of solid elements or compounds *
True
False
Answer:
True
Explanation:
Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Furthermore, the chemical composition (property) of a mineral reflect the presence and arrangement of atoms in each.
Due to the fact that these molecules are structurally arranged (ordered) and are repeated by different symmetrical and translational operations, they determine the shape of minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
Additionally, inorganic-crystalline solid substances which are found naturally within earth are referred to as minerals.
In conclusion, a mineral in the earth's crust exists naturally in form of solid elements or compounds.

Mike roller skates with a constant speed of 10 miles per hour. How long will he take to travel a distance of 15 miles.
Answer:
So every hour he makes 10 miles. So he would take 1 and a half hours to go to Mcdonalds 15 miles away.
Explanation:
[tex]\huge\boxed{{\textsf{90 minutes}}}[/tex]
We know that Mike's speed is [tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}[/tex] since there are [tex]60[/tex] minutes in an hour, and we know that MIke needs to travel [tex]15[/tex] miles. We'll model this using fractions:
[tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}=\dfrac{15\ \text{miles}}{x\ \text{minutes}}[/tex]
We can see that there is a [tex]2:3[/tex] ratio here, so we'll divide the left fraction by [tex]2[/tex] and multiply it by [tex]3[/tex] to get the right fraction.
[tex]\dfrac{10}{60}\Rightarrow\dfrac{5}{30}\Rightarrow\dfrac{15\ \text{miles}}{\boxed{90\ \text{minutes}}}[/tex]
