The correct option is (a).

Explanation:

One Atomic mass unit is the mass of an atom. It is defined as the mass of a single carbon -12 at rest.

The relation between amu and kg is given by :

[tex]1\ amu=1.66\times 10^{-27}\ kg[/tex]

Hence, one amu is equal to the mass of a single atom of carbon.

Answer:

Explanation:

Average velocity is found in the total displacement experienced in the trip divided by the total time it took to make this trip. If, for the first 2.0 hours, the car travels at 60 km/hr, then in 2.0 hours the car can travel 120 km; if it then travels for 3.0 at 85 km/hr, it can travel 255 km in the same direction. The total time this took was 5.0 hours. So doing the math and rounding correctly by following the rules for the adding and subtracting of sig fig's:

[tex]v=\frac{120+255}{5.0}=\frac{380}{5.0}=76\frac{km}{hr}[/tex]

If you do not round when you add, the average velocity is 75 km/hr

Answer:

La opción correcta es la A) 22 km y 78 km.

Explanation:

Dado que el desplazamiento (D) es un vector, su valor viene dado por la suma algebraica de los vectores del desplazamiento de ambos tramos.

Como en el primer tramo movil se mueve en la dirección de x-positiva y en el segundo tramo se mueve en el sentido de x-negativo, tenemos:

[tex] D = (60 km - 10 km) - (60 km - 32 km) = 22 km [/tex]  

Ahora, la distancia (d) es una magnitud escalar, por lo que su valor viene dado por la suma del desplazamiento de ambos tramos:

[tex] d = (60 km - 10 km) + (60 km - 32 km) = 78 km [/tex]                

Por lo tanto, la opción correcta es la opción A) 22 km y 78 km.

Answer:

0.25 m

Explanation:

Given that,

The speed of sound, v = 330 m/s

The frequency of the note of the instrument, f = 1320 Hz

We need to find the wavelength of the sound wave.

We know that,

Wavelength, [tex]\lambda=\dfrac{v}{f}[/tex]

Put all the values,

[tex]\lambda=\dfrac{330}{1320}\\\\\lambda=0.25\ m[/tex]

So, the wavelength of the sound wave is equal to 0.25 m.

Answer:

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Volume of value V = 0.5333 [tex]m^{3}[/tex]  is below the water line .

Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.

F(b) = rho*g*V

F(b) = buoyant force

rho = fluid density

g = acceleration due to gravity

V = fluid volume

given

density of raft = 373 kg/[tex]m^{3}[/tex]

volume of raft = 1.43 [tex]m^{3}[/tex]

since, density  = mass / volume

mass of raft = density * volume

                    = 373 * 1.43 = 533.3 kg

using Archimedes principal

Force = density of liquid * volume of liquid displaced * acceleration due to                gravity

  mg        = 1000 * V * 9.8

  533.3 * 9.8 = 1000 * V * 9.8

  V = 0.5333 [tex]m^{3}[/tex]

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti

Explanation:

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti. Most of the buildings in Haiti do not fit in the building byelaws norms as most of them were constructed in a short period of time with less engineering and at cheaper rate. While building in Chile were built adhering to the building codes and byelaws.

The base of the building is Chile were separated from each other using the “base isolation” technology and the were also more flexible as compared to the buildings in Haiti.  

The skyscrapers in Chile were constructed in a way that they can float on the arrangements of ball bearings and padded cylinders

Answer:

When the apple falls from the tree, it has some gravitational potential energy due to its height. Now, When it starts falling, the Gravitation Potential energy will starts converting into the Kinetic Energy. When the apple is about to strikes the ground, the Gravitational Potential energy have been converted into the Kinetic Energy.

Explanation:

The potential energy will be low when its kinetic energy is high and vice versa. But the mechanical energy remains conserved.

Mechanical energy can be explained as the sum of kinetic energy and potential energy that can be used to do work. Mechanical energy can be described as the energy of a body due to its motion or position.

The total mechanical energy of a physical system is conserved as the energy can not be created or destroyed. The mechanical energy of a physical system can only be transformed from one form to another when the forces acting work are conservative in nature.

Each force is related to potential energy form and the energy changes between different kinds of potential energy and kinetic energy but the total energy remains constant.

The mechanical energy of the apple remains conserved. As the apple falls its potential energy is converted into kinetic energy.
