Ideal Mechanical Advantage (IMA) can be found by using the formula:

IMA = ID/OD

ID = Input Distance

OD = Output Distance

In the question, we are given:

ID = 150

OD = 75

Now, solve the expression with what we have.

IMA = 150/75

IMA = 2

Therefore, the IMA is 2.

Indicate what a specific property of matter is. Also explain why the specific properties of matter are useful compared to the general ones.

Solution

The specific properties of matter are properties that describes the intensive properties of the system. They are properties that do not depend on or change with the extent or size of the system. They are usually obtained by dividing the generalised properties or extensive properties by the extent or size of matter to make them independent of size/extent/Mass.

Examples of specific properties include specific heat capacity, specific volume etc. They usually have units of general units/Mass units.

The specific properties of matter are more important than the general ones because

- They help in general comparisons of the properties of different materials. They are used to rank, classify and compare properties of different materials.

- They are used in reference table/data to easily record easily accessible properties of matter. It helps to record standards that are general and independent of sizes/extents/Mass, thereby keeping the reference table/data/chart precise and concise.

- They provide us with values that are easy to memorize and remember, unlike trying to cram the different properties of different masses/sizes of matter.

In Spanish/En español

Las propiedades específicas de la materia son propiedades que describen las propiedades intensivas del sistema. Son propiedades que no dependen ni cambian con la extensión o el tamaño del sistema. Por lo general, se obtienen dividiendo las propiedades generalizadas o las propiedades extensivas por la extensión o el tamaño de la materia para hacerlas independientes del tamaño / extensión / masa.

Los ejemplos de propiedades específicas incluyen capacidad calorífica específica, volumen específico, etc. Usualmente tienen unidades de unidades generales / unidades de masa.

Las propiedades específicas de la materia son más importantes que las generales porque

- Ayudan en las comparaciones generales de las propiedades de diferentes materiales. Se utilizan para clasificar, clasificar y comparar propiedades de diferentes materiales.

- Se utilizan en la tabla / datos de referencia para registrar fácilmente propiedades de materia fácilmente accesibles. Ayuda a registrar estándares que son generales e independientes de tamaños / extensiones / masa, manteniendo así la tabla / datos / tabla de referencia precisa y concisa.

- Nos proporcionan valores que son fáciles de memorizar y recordar, a diferencia de tratar de agrupar las diferentes propiedades de diferentes masas / tamaños de materia.

Answer:20kgm/s

Explanation:

Mass=10kg

Velocity=2m/s

Momentum=mass x velocity

Momentum=10 x 2

Momentum=20

Momentum=20kgm/s

The object with mass m when moving with the velocity, its momentum can be calculated. The momentum of the object A is 20 kg.m/s.

Momentum is the product of mass and velocity of a moving object.

If the momentum is p, the mass of the object is 10 kg and the velocity is 2.0 m/s, then the momentum will be

p = 10 × 2.0

p = 20 kg.m/s

Thus, the momentum of the object A is 20 kg.m/s

Answer:

A rectangle has two dimensions:we can measure its length and,perpendicular to that,its width.

Explanation:

When using the lens equation, a negative value as the solution for d baseline i indicates that the image is Virtual. The correct option is B.

When a light strikes on a shiny surface, it reflects back the light ray in the same medium. The phenomenon is called reflection and the ray is called the reflected ray.

From the Len's maker formula, e have

1/f = 1/u + 1/v

where f = radius of curvature /2

So, the negative value as the solution for d baseline i indicates that the image is Virtual.

Thus, the correct option is B.

Answer:

The answer is "C. 3.0 ohms". 

Explanation:

Ohm's law states the following:,

V = IR

where:

Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts

Current (I) = 2.0 amps

Resistance (R) = ? ohms

To solve for Resistance (R) the equation must be rearranged this way:

 R = V / I

Then, the variables must be replaced with the known values:

 R = 6.0 volts / 2.0 amp

R = 3.0 ohms

The answer is  C. 3.0 ohms.

Answer:

45 cm ( in my opinion)‍♀️

Explanation:

( Using the mirror formula)

1/ u + 1/v = 1/f

( introducing magnification; m into the formula )

u( 1/u  + 1/v ) =u×1/f

1 + u/v =u/f

( But u/v =1 ÷v/u= 1/m)

1 +1/m =u/f

1 + 1/2 =u/30

2+1= u/15

3=u/15

3×15=u

Answer:

white

Explanation:

This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.

Now, in diffraction fo a single slit we always have a central maximum (for all the colors)

This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white

The first and second velocities of the car, with four washers attached to the pulley, are both 0.125 m/s.

We must apply the following calculations to determine the car's first and second velocities with the four washers attached to the pulley:

v1 = 0.25 m / t1

v2 = 0.25 m / (t2 - t1)

Here, t1 denotes the typical time needed for the car to go 0.25 metres, and t2 is the typical time needed to travel 0.50 metres.Let's say that t1 and t2 are the typical times, each lasting two seconds on average.The first formula allows us to determine v1:

v1 = 0.25 m / 2 s = 0.125 m/s

Using the second formula, we can calculate v2:

v2 = 0.25 m / (4 s - 2 s) = 0.125 m/s

Table E can be used to record these values as the velocities at the relevant distances.

Answer:

velocity term

Explanation:

Answer:velocity term

Explanation:

Answer: 366.56 meters.

Explanation:

Velocity of the cannon ball = 425m/s

Velocity of sound = 345 m/s

For the "position" of both, we have the equation:

Pc = 425m/s*t

Ps = 345m/s*t

Where t is time in seconds.

If the position of Chris is X, we have that if the ball reaches the position of Chris in T seconds, then the soundwave reaches the position of Chris in T + 0.20 seconds, we can write this as:

425m/s*T = X

345m/s*(T + 0.20s) = X

Now we can solve this system of equations. First we can replace the first equation in the second equation and get

345m/s*(T - 0.20s) = 425m/s*T

Now we solve this for T.

345*T + 69 = 425*T

69 = (425 - 345)*T = 80*T

T = 69/80 = 0.8625 seconds.

Now we replace this in the first equation and get:

X = 425m/s*T = 425m/s*0.8625s =  366.56 meters.

Answer:43.6°

Explanation:

Refractive index=n=1.45

Critical angle=c

n=1/sinc

1.45=1/sinc

Cross multiply

1.45sinc=1

Divide both sides by 1.45

(1.45sinc)/1.45=1/1.45

sinc=0.6897

c=sin(inverse)(0.6897)

c=43.6°

Critical angle is 43.6°
