Use the information from the graph to answer the question. What is the acceleration of the object

Answer:

True

Explanation:

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them

Explanation:

According to the question, the refractive index of the solid is approximately 2.42.

The refractive index may be defined as the measure of the bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance, n = c/v.

The Refractive index for a medium may be defined as the ratio of the speed of light in a vacuum to the speed of light in that particular medium. It is a pure ratio and hence it does not have a unit.

According to the question,

The speed of light in a solid = 1.24 × 10⁸ m/s.

The refractive index of the solid = ?

The formula for the Refractive index of a medium = (Speed of light in vacuum) / (Speed of light in the medium).

The Speed of light in vacuum = 3 × 10⁸ m/s

[(3 × 10⁸)m/s] ÷ [(1.24×10⁸)m/s]

= (3×10⁸)/(1.24×10⁸)

= 3/1.24

≈ 2.42

Therefore, the refractive index of the solid is approximately 2.42.

At different points on Earth's surface, the free fall acceleration ranges from 9.764 m/s2 to 9.834 m/s2[2] depending on altitude and latitude, with a conventional standard value of exactly 9.80665 m/s2 (approximately 32.17405 ft/s2). Locations of significant variation from this value are known as gravity anomalies.

Explanation:

The water table maybe defined as the boundary between groundwater saturated spaces and the soil surface. In more explicit terms, the table table is the water level in shallow dug wells. That is when a well is dug, the position of water in the well is called the water table. The water table may rise during the rainy season or areas of high water volume such that the water table meets the the land surface, when this occurs, we have the formation of a spring. This flow is the channeled to streams, rivers or lakes.

Lakes are generally a body of water surrounded by land.

Additional comment

This is physics, not math. In the physical sciences, most numbers must be considered to be measurements. (A few are definitions.) Hence, the rules of significant figures and precision apply to the results of arithmetic operations. This problem is a good illustration of what happens when computing small differences of large numbers. We start with 3 significant figures in 0.205, and end up with 1 significant figure in 0.004.

Las limitaciones de un modelo o prototipo son;

1) Los parámetros ambientales (donde se opera el modelo, prototipo o producto) son diferentes y, por lo tanto, pueden producir relaciones y factores ambientales que serán diferentes de los factores ambientales y las relaciones del objeto real.

2) El análisis del problema puede ser inadecuado

3) La posibilidad de falta de satisfacción del cliente con un modelo, preferencia por la demostración real del producto.

4) Reproducción inexacta del entorno del producto durante la prueba del modelo

5) El factor de costo del modelo

6) Mayor complejidad introducida por el modelo / prototipo al análisis de la solución

El modelo o prototipo es la presentación del diseño articulado, construido para demostrar el producto real con el propósito de encontrar la existencia de errores en el diseño que serían corregidos, antes de que se realice la producción real

When the brake is applied to the car and comes to rest after some time is an example of an object that is slowing down.

The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.

1. When the brake is applied to the body and comes to rest after some time is an example of an object that is slowing down.

2. When a person accelerates the car and the velocity is increasing is an example of speeding up.

3. An object moves in a circular motion moving at a constant speed but changing direction,

4. Acceleration is the rate of change of velocity. If the change in the velocity is constant the acceleration is zero is an example of moving at a constant velocity with zero acceleration.

Complete question:

A college dormitory room measures 14 ft wide by 13 ft long by 6 ft high. Weight density of air is 0.07 lbs/ft3. What is the weight of air in it under normal conditions?

Answer:

the weight of the air is 76.44 lbs

Explanation:

Given;

dimension of the dormitory, = 14 ft by 13 ft by 6 ft

density of the air, = 0.07 lbs/ft³

The volume of the air in the dormitory room = 14 ft x 13 ft x 6 ft

                                                                          = 1092 ft³

The weight of the air = density  x  volume

                                   = 0.07 lbs/ft³  x  1092 ft³

                                   = 76.44 lbs

Therefore, the weight of the air is 76.44 lbs

Answer:

only long-range force that affects all particles is the gravitational force.

Explanation:

In nature there are four fundamental forces: nuclear, weak, gravitational and electrical.

The last two are long-range, that is, the forces are zero for infinite distances, the current gravitational on all the particles and the electric one acts on the charged particles, without the chosen charge it is zero, the forces is also zero.

Consequently the only long-range force that affects all particles is the gravitational force.

Answer:

1. The tightness of the wire has no effect on the strength of the electromagnet

2. The strength increases with the number of coils

3. The strength of the electromagnet increases with the number of dry cells used

4. The strength of the electromagnet increases with the wideness of the nail but not the length of the nail

Explanation:

The strength of an electromagnet is given by the following relation;

[tex]B = \dfrac{\mu_0 \cdot K \cdot N \cdot I}{L}[/tex]

Where;

B = The magnetic field strength at the center

μ₀ = The magnetic permeability of free space = 4·π × 10⁻⁷ N·A⁻²

N = The number of loops formed by the conductor around the core

I = The current flowing through wire coiled around the nail

K = The magnetic permeability of the nail

L = The length of the coil

Therefore, we have;

1. From the above equation, the tightness of the wire coil around the nail (or the radius, 'R', of the wire) does not does not affect the magnetic field strength

2. The number of coils, 'N', is directly related to the magnetic field strength, 'B', and therefore, increasing the number of turns or coils around the nail, increases the magnetic field strength

3. The current in the circuit is directly related to the magnetic field strength and the number of dry cell used increases the current in the circuit and therefore, can increase the magnetic field strength

4. The size of the nail used in a solenoid and the magnetic field strength are directly related. The wider the nail, the stronger the magnetic field

Answer:

The velocity of an object thrown straight up would be zero at maximum height (just before it starts falling)

Find the initial velocity:

Time = speed/gravitational constant.

Speed = gravitational constant * time

Initial speed = 9.81*3.16

Initial speed = 30.9996

Maximum height:

h = Vinitial^2/ 2g

h = 960.9752/ 2*9.81

h = 48.979368
